Easy Egg Science Projects

In this article we will look at some interesting experiments and science fair projects you can easily do with eggs from the refrigerator. You will discover that the common egg has some amazing properties you might not be aware of.

There are a number of egg science projects you can do but I will mention just a few here to spark your interest. I’m sure you will be able to think of many more by using a little imagination.

The Egg Drop Science Experiment

For this experiment you will come up with a way to cushion an egg in a small container so it doesn’t break when dropped from a certain height. You can use something like a small coffee can that leaves enough room for your packaging around the egg to protect it from the fall.

You will need to do a little research to determine what might be suitable materials to keep the egg from breaking. Lots of room to experiment here for sure with different materials and arrangements of the egg in the container.

Do all your drop tests from a set height such as six to eight feet. Also drop the container on the same surface each time to keep your results consistent. As always with any science project, keep records of what you did and the results of each drop test.

The Crushing Strength Egg Science Project

One very interesting feature of eggs is their strength. That strength though is very dependent on the orientation of the egg to the force or weight that is applied to it.

So for this experiment you will determine if eggs are stronger lying flat or standing upright. You may also get an idea of how much stronger they are in one postion than the other. I think you will find this very surprising just how much a difference the position of the egg makes.

What you will need for this egg science project:
1. An empty egg carton
2. Some books
3. A couple of small trash bags
4. Some tape
5. A scale to weigh the books(optional)

Remove the top from the carton and place four eggs toward the center and in a rectangular arrangement. Leave a space between them on each row. Place a plastic bag on the table under the carton. Place the other bag over the eggs.

Now start placing books on the eggs one at a time. Make sure they are even and don’t tip over. See how many you can place before an egg breaks. Weigh all the books used if you have a scale. You now have an idea of their strength end-to-end.

Test their strength lying flat:

Place a bag on the table and make four loops of tape with the sticky side out. Place the tape on the bag in about the same arrangement as the eggs were in the carton. This is to keep the eggs from rolling around.

Place another bag over the eggs and then start placing books. How many books did it take before an egg broke. Weigh the books if you have a scale. You now know whether eggs are stronger upright or lying flat. And you have an idea how much stronger they are in that one position than the other.

I hope you enjoyed these experiments and use your imagination to develop even more interesting egg science projects you can do at home.

Easy Science Fair Porjects – Great Topics

What to do and what is the easiest science fair project? Picking a topic for easy science fair projects is a huge deal for a kid, no matter what the age. There are so many different topics and ideas for all grades; you can find a great one for any child, with almost any interest!

When thinking about easy science fair projects, take into consideration your child’s interests, does he or she love birds, or hate them?

Science fair projects are easy If your child loves the topic so if your budding young scientist loves the outdoors, hiking, camping, and nature, then you might want to consider projects that relate to that. “What is Lightening” is often fun for the child whose imagination is often captured during thunder storms. Depending on the time of year, your child could build his or her own snow gauge and use it. Making a barometer is often a favorite, too.

For older children it is a bit harder. Learning about the body and how it works is something that a lot of children like to do, considering at that age many aspire to be doctors or nurses – learning about the cardiovascular system is educational, and making a scale model of a heart can be tons of fun. Also, learning about blood and studying blood related diseases is very popular, you just might surprise yourself and find that it is in fact easier that you think.

For the little computer whiz in the family, there are hundreds of easy science fair projects that tailor to their interests. In most large bookstores there is a section on building your own robot, and some are rather cheap (The robot, not the books. Although if you shop around you might find that the books are cheap too). A small, electronic gadget that your child has made is something that they will always have, and it will help build confidence in them that they can do something important, involving what they love.

A classic, but still a fun and easy activity, is making a model of the solar system using fruit – orange for the sun, apple for Mars, etc. The local library would have tons of information on this subject – just make sure there is no Pluto, who is not considered a planet anymore, but a piece of something that got caught in our solar systems gravitational field.

Projects with magnets are a favourite – making your own magnet is a very inexpensive and simple project that looks impressive. Your child could study the effects that magnets have on seedlings and their growth, or on healing.

As a parent, I am sure you want to help your child as much as possible to complete their science project – but remember that it is their project, and it is not your place to do their work for them, no matter how much you might want to.

Easy Science Fair Projects Kids Can Do

Doing science fair projects should be fun for the kids. Here is one of our easy science fair projects kids can do that is fun. It needs very little supplies, it also needs very little work, but it will need a little time. It is very easy though and if you have the time the kids will get a trill out of it.

In this experiment kids are going to look at how organic matter decomposes. Your kid will see that soil teems with life such as worms, slugs, millipedes and beetles that feed on the decaying matter. The decomposers are microscopic bacteria, fungi, woodlice, mites and small insects. This decomposing is the process where all organic material is turned into rich fertilizer for the growing plants in the soil.

This project actually consists of two easy science fair projects for the kids to do. The first your kid is going to look at the conditions needed for the decomposing process and in the second your kid is going to look at the decomposers.

Remember to make meticulous notes from your hypothesis to your conclusion and for your display purposes it is a good idea to take photos of each step as you go.

Having a look at the optimal conditions for the decomposing process:

What you need:

* A trowel
* Good soil
* Dead leaves
* Water and a watering can
* Two clean plastic containers, one with a tight lid
* Tags
* Pen
* Note book
* Camera
* Plastic gloves

This is what you have to do:

Wear your gloves for both of these experiments

1. Remember your notes and photos
2. Using your trowel fill the two plastic containers three quarters full with dry soil
3. Place a layer of dead leaves on top of the soil in both containers
4. Mark the container with the lid “A” and the other “B”
5. Now you water the soil and the leaves in your container marked “A” thoroughly and press the lid on
6. Keep the soil and leaves in the container marked “B” dry, do not add any water to it
7. Place both containers in a dry place and wait a few weeks
8. Have a look at both and you will notice that the leaves in the wet soil will have begun to rot while the leaves in the dry soil has dried and shriveled.

In the next experiment that is the second of our easy science fair projects for kids to do we are going to look at the decomposers.

What you will need:

* Once again your plastic gloves
* A plastic funnel
* A large clear jar with a neck into which the funnel will fit
* Some rotting leaves from a compost heap
* Black paper
* Sticky tape
* A desk lamp
* A magnifying glass
* A field guide
* A notebook
* A pen
* A camera

This is what you have to do:

1. The plan is to see the insects on the rotting leaves
2. You are going to separate them by using a lamp, a funnel and a large jar
3. Place the funnel in the jar
4. Wearing your gloves loosely fill the funnel with your rotting leaves
5. To keep out the light, you have to tape the black paper around the sides of the jar so it is dark inside the jar
6. Now you place the lamp in such a position that it shines onto the leaves in the funnel
7. What you want to happen is for the insects on the leaves to move away from the heat and light from the lamp
8. While doing so they will fall down the funnel and into the jar.
9. After an hour, take a way the lamp and remove the black paper from the jar
10. There will be several insects in the jar
11. Identify them by looking at them with the magnifying glass and the field guide
12. When you are finished, return them to where you found them and be careful not to kill them. These creatures are very important in the eco system of the earth!

As you can see, kids will be able to the most of the work in these two easy science fair projects for kids to do. The two combines should give you enough material for a good display.

There are things you need to know about doing a science fair project in the correct way. For all the info have a look at Magriet’s Squidoo Lens: Good Science Fair Projects and for another one on the role of decomposers have a look at her site Easy Science Fair Projects.

Easy Science Fair Projects To Do On Short Notice

Maybe you have left it too late and now you need science Fair Projects you can do quickly. Well, you’re in luck, here is a fun and easy one you can do in less than 24 hours! This is one of our many easy science fair projects to do on short notice

This experiment is about heat absorption. You are going to try and find out which colors absorb more heat than other.

Here are the questions you should be able to answer after you have completed this science fair project:

  1. Which ice cube melted the most?
  2. How did the colors effect the melting of the ice cubes?
  3. What does this fact tell you about the heat absorption of colors?
  4. Do dark colors absorb more heat than light colors?

Now we have to start our experiment:

Do you know what the first thing is you need to do? Yes, you have to formulate your hypothesis! In doing this experiment to see which ice cube, covered in different colors, melts the most, what do you think your hypothesis should be? Okay it is: Do dark colors absorb more heat than light colors.

What you need for this easy science fair project (it is called the materials):

  • Several different colors of fabric about 6 or 7 inches square, as many as you can but at least 5 different colors
  • A pair of scissors
  • An ice cube for each color of fabric, the ice cubes must be more or less the same size
  • A good food scale that can weigh very small differences
  • A large cookie sheet or a tray
  • A pen
  • A note book
  • A camera

How you have to do this experiment (it is called the procedure):

  1. Cut the pieces of fabric to a size a little larger than the tops of the ice cubes
  2. Now you have to weigh each ice cube and make a note of the weight
  3. Place the ice cubes on the cookie tray
  4. Take a photo for your display
  5. Cover each ice cube with a piece of fabric
  6. Make sure you write down which color you placed over which ice cube as you have to work out the percentage of weight each cube lost late on.
  7. Once again take a photo for your display
  8. Place the cookie tray in direct sunlight
  9. Leave it for 15 minutes, if it is not too hot. If it is very hot and the cubes are going to melt very fast you have to check on them sooner. This you will have to work out for yourself
  10. Take a photo for your display
  11. Bring the ice cubes back in and take a photo for your display
  12. Weigh each ice cube as fast as possible to prevent further melting
  13. Write down each one’s weight
  14. Now you have to determine the percentage of weight each cube has lost. This is how you do it: you take the beginning weight of the ice cube and you subtract the end weigh of the ice cube from it. This amount you divide by the beginning weight multiplied by a hundred to get the percentage. A formula to show you this will be easier:

(Beginning weight) – (final weight)/ Beginning weight X 100 = percentage melted

Can you think of what else you can do for your display now? Yes, you have to make a graph to show the differences in percentage each ice cube melted.

Now you can come to your conclusion about the difference in heat different colors absorbs.

If you have more time for science fair projects to do, you can take this experiment further by doing the same, but placing the tray in the fridge or by covering it with a cardboard box to see if it makes any difference to the results and to formulate why you think it makes a difference. For instance, does the heat absorption of the cardboard box play any role in it?

Do you still need more science fair projects to do? Magriet’s site “Easy Science Fair Projects” has many more Elementary Science Fair Projects and others. You will also find lots of good ones on her blog KnackTrack.ScienceProjects.

Easy Science Projects For Kids

It’s important for kids to get involved in science from an early age, as exposure to scientific ideas and the world of exploration as soon as possible is the best way to foster a love for learning in your children that will last a lifetime. At the same time, scientific knowledge is cumulative, so kids have to start with a solid foundation if they are to develop the necessary scientific skills to succeed in school, and perhaps in a future career. Of course, when doing science projects with kids the most important thing to remember is to have fun! Youth science fair projects aren’t meant to transform your child into a scientist – they are meant to get the creative juices flowing within your child and help him or her continue to explore the natural world and make use of the imagination.

So where do you find ideas for science projects, if you want to get your child started on something at home? Luckily, these days you don’t have to look far to find science projects for your children – simply do an online search and you should be able to find tons of websites containing information and ideas pertaining to science fair projects and science for children in general. These websites list science projects and tell you exactly how to do them and what to do, so the process of helping your child discover science or prepare science fair projects for school is made easy.

In the past, it was easy for parents to become frustrated when helping kids with homework and coming up with ideas for science fair projects – now it’s easy to help them out and you don’t have to be a science whiz yourself! And if your child demonstrates a natural interest in science, it’s even more important that you encourage it from an early age. Whether or not you have to do a project for school, or complete a homework assignment, kids getting involved in science at home is a great idea!

In fact, doing their own science experiments at home is a great way to supplement the regular educational exposure your kids get during the day in the classroom. And if you home school your children coming up with fun and educational science experiments that are easy to recreate at home is the perfect way to help your kids exercise their minds and learn about science while having a lot of fun at the same time.

When you set up science projects for your kids to do at home, it makes learning fun – this will carry over to the child’s classroom experience and may even improve their grades overall. Of course, that is not the main goal of doing science experiments at home. Again, do these projects with your children as a fun activity and the learning will spring from that organically. Specifically, when searching for science projects for your kids to do at home it’s a good idea to find something your children, and maybe even their friends, will enjoy. Figure out what interests your child and go from there. Involving them in the process will help them naturally discover where their interests are and what type of experiments they’ll gain the most from.

You can find the instructions for these experiments for free, although you will have to purchase some basic supplies in most cases. At the same time, materials used in most of these projects are relatively inexpensive and not difficult to find.

Finding Good Ideas for the Science Fair Projects

Finding good ideas when it comes to playing with the periodic table of elements and creating an interesting science project is very important because such ideas may motivate you in order to develop interesting theories by yourself. Every project is a genuine travel that is led by curiosity; this curiosity should result into positive effects on the student scientific research because even the simplest project is likely to be interesting if created in a provocative and challenging manner. The project may start with simple questions but it may also end up with interesting discoveries that will be demonstrated in a scientific manner by using the required methods. The simple questions can actually be developed in order to create a real experiment or even a procedure that is to be applied in order to demonstrate the final conclusions.

If the Science fair projects are good, they will not consume your money and time. They will not be transformed into daunting tasks either and you may be able to have some fun while creating these projects. But every projects is likely to require a well thought plan in order to work in the desired manner. Bright ideas are also expected to come from every student who is interested in demonstrating his projects by using the periodic table of elements. The project may become a frustrating task if you leave it for the last minute; you have to avoid this condition because time is required when it comes to creating a successful science project that involves various experiments. Therefore, every project should be made to happen according to scientific methods and the results are likely to be improved as well especially if you are interested in learning more about a certain chemistry experiment or knowledge.

There are various ways when it comes to improving the direct results of the Science fair projects; for instance, the project will direct every student who is involved towards prospects or specific results that are to be obtained through the specific theories and experiments. These experiments must be directed in order to become scientific ones because the undirected and uncontrolled experiment is not likely to lead to a scientific result that may be demonstrated according to the existing methods that are used in the chemistry field. The background research is another key element when trying to conduct a scientific experiment or project; the specific procedure will be developed in order to investigate the direct hypothesis that is the center of the entire project.

The student needs to learn how to collect and experiment the necessary data in order to conduct the entire experiment. After the necessary analyzing process, you will be able to derive the conclusion because this conclusion must be based on scientific research and experiment. The entire project should be displayed in a well thought manner in order for every person to understand its main course. The means that are used during the project are to be explained as well in order for the audience to have a clear picture of everything that has happened along the process.

You should not rely on the fact that every person is likely to be pretty familiar with the periodic table of elements because this knowledge can be missing. You will have to describe the entire process in a clear manner and you will have to develop the direct results in order to reach the necessary scientific conclusion. The basic process and its main levels are to be followed in order for the project to be a successful one that may convince the audience. The basic process should be reached in the right manner because this is the key element when it comes to providing the audience with a clear picture of the Science fair projects. The right order is to be obeyed in order for the student to make a clear presentation of his project; you have to stay away from constant improvising because this is not the right moment to demonstrate your imaginative skills that are not related to the project itself.

The display of a certain project is everything that really matters when judging the process; the judges are likely to pay attention to the way in which a particular project is being displayed in order to understand the inner mechanism that has helped the student in order to reach the final scientific conclusions. Memorized speeches and descriptions are to be avoided because they can frustrate the judges. Certain questions are also to be practiced in order for the student to correctly answer them when asked by the judges.

The Science fair projects must be developed according to an established scheme and the student must stay away from improvising when it comes to the periodic table of elements

Fun & Easy Science Fair Projects Kids Can Do

Science fair projects kids can do needs to be fun and easy. In this, one of our science fair projects kids can do, we are going to have a look at water and water evaporating and condensing. The kids will be able to see what happens in each step even though they will have to practice a little patience as things takes a little while to happen.

These two projects will teach kids very good basics to let them understand why they have to do their bid for nature and help slow down global warming by caring for our plant life.

Here is the first one:

Automatic irrigation:

What you will need for this experiment:

• A large rectangle flower box with a few plants growing in it

• A bottle

• Water

What you have to do:

1. Fill the bottle with water

2. Push it, upside down, into the soil in the flower box

3. You will notice a air bubble rising in the bottle as the plants use the water.

4. The water in the bottle will only keep on running into the soil until the soil is completely whetted.

5. Only once the plants have used some more water in the soil and air can escape through the dry soil into the bottle

6. How long the water will last will depends on the weather, how hot it is, how humid it is etc.

7. Now repeat this experiment, but first loosen the soil around the plants a little, being careful not to damage or expose the roots.

8. You will notice that the loosened soil absorbs the water easier.

9. Can you think why?

10. Now explain what you have done and what the conclusion is concerning water and air.

11. You have to explain why the water stops seeping into the soil once it is completely whet and why it starts again once the plants have used some of the water and some of the water in soil have evaporated into the air.

Now for the second of our science fair projects kids can do:

Rain in a flask:

Here we are going to show that water evaporates through small pores in leaves.

What you will need for this experiment:

• A green leaf

• A glass filled with water

• Oil

• A glass flask big enough to fit over the glass of water with the leaf in it

What you have to do:

1. Place the leaf in the glass with water

2. Throw a thin layer of oil on the water

3. Cover the glass and leaf with your glass flask

4. Wait a little while and observe what starts to happen

5. Why does it happen?
