Earth Science Projects – Ideas that Are Down to Earth

earth science projectEarth science projects are an amazing way for kids to become interested in science as well as the earth around them. There are a lot of “earth sciences”, giving kids lots of cool possibilities for experiments and demonstrations. Here are five down to earth ideas for your project:

1. Find out if salt affects the boiling point of water. Using distilled water, measure the temperature at which water boils with different amounts of salt added. This easy experiment can be done fast – in under an hour!

2. Test types of insulation to see which works best. Freeze bottles of water, insulate them with various building materials, and see which one stays frozen the longest. This is science project is great for students concerned about our environment.

3. Make a tornado. Simply half fill a clear 2 liter soda bottle with water, and swirl it until it makes a tornado. This is an easy elementary demonstration, that probably won’t win the science fair, but will fascinate younger students while allowing them to observe swirling currents. (We bet you’ll get a kick out of it, too!)

4. Measure the amount of oxygen that is in air. Put duct tape on a hand warmer, activate it, and quickly tape it to the bottom of a tall jar. Invert the jar and put the mouth into a pan of water. As the hand warmer heats up, it will use up the oxygen in the glass, causing the water level to rise. If you’re traveling to and from the mountains and compare the amounts of oxygen, this is a great experiment. Otherwise, it’s a cool demonstration.

5. Compare brands of toilet tissue to see which is most biodegradable. Weigh samples of different brands of tissue, place them in water and allow them to break down. After a day, ‘flush’ the samples through a funnel, then weigh what is left. Your results may change your shopping habits! Get the instructions for this earth science project here.

Easy Science Projects – Guest Author

Easy science projects with elementary kids aren’t always done for the science fair. Sometimes, you’re just looking for something for fun. Here is a guest writer to share some easy science project ideas that you probably can’t take to the fair, but that are a whole lot of fun!

If you do need an easy science project for school, check out 24 Hour Science Projects.

Most parents and especially homeschoolers are always on the lookout for easy science fair projects to do with the kids. Here is one of our very easy science fair projects to do with the kids. In this project you are going to look at how ships float.

Simple boats such as rafts float because they are made of material that is lighter than the water. Usually materials such as light wood or reeds that are less dense than water are used.

Heave boats works differently as they float because of the upthrust of the water that occurs because of them pushing on the water. The upthrust is their pushing force. By putting something on the water and letting it go, you will see that it is pushing the liquid out of the way. The further it goes the more water it pushes up. Now, when this upthrust becomes the same as the objects weight, the object will float. This is the principle uses for boats.

Now, here is a very simple experiment to test upthrust:

What you will need for your project:

2 polystyrene blocks, one double the size of the other
A tank or a bowl of water
A wooden block
A Marble

Method for this easy science fair project to do with the kids:

Place the two polystyrene blocks in the water
Notice that they float because they are made of very light material
So, for them to float only a small amount of upthrust is needed
Now you can try and push them under the water
You should be able to feel the upthrust pushing back
Place the wooden block in and you will notice that it floats deeper in the water because it is heavier or denser than the polystyrene blocks
Now drop the marble in, you will notice that it sinks immediately as the upthrust is not enough to keep it floating

When doing a project such as this, remember to make notes of all your steps and to take photos for your display. It is also important to make use of the proper scientific method to ensure you do a good project.

In this project, what would you say is your hypothesis?
Which part of this experiment is your control?
How would you describe your method?

These are some of the things you will have to know in order to do a winning science fair project. Even easy science fair projects to do with the kids, needs to adhere to this as they have to learn from the very beginning to do it correct.

The next easy science fair project to do with the kids..

Making use of the upthrust with a hollow hull

What you need for this experiment:

A pair of scissors
Kitchen foil about 20cm X 15cm
Kitchen paper towels
The same tank of water
Marbles

How to do this easy science fair project:

First of all place the flat piece of kitchen foil in the tank
Give it a slight push and notice that it sinks with the slightest push because it does not replace a lot of water, so the upthrust in minimal
Remove the foil from the water and carefully dry it with the kitchen paper without tearing it
Now you have to carefully, without tearing the foil, model it into a simple boat shape with your fingers
Place your boat in the water
What happens?
Why does it happen?
Now start filling your boat with marbles, as your cargo
What happens now?
Why does it happen?
How many marbles can you place in your boat before it sinks?
Why does it eventually sink?

In answering these questions, think of the experiment above. Now you have demonstrated how a boat works. Even though it is made of metal, it is filled with a lot of air and this creates enough upthrust to make it float. If the boat is overloaded though, it will eventually sink.

These is only two very simple examples of Easy Science Fair Projects To Do with kids, working with boats.

More Winning Science Fair Projects

winning science projectJust got a note from yet another mom whose kids have won with our science project guides! Note that she’s used them for more than one year – and she only purchased once!

I want to let you know that my boys and I absolutely love these projects. I have two boys who have competed in the science fair for the past four years. Every year but one both of my boys have won and gone to regional, including this year as well. We have fun and enjoy doing the experiments!

Your child can have one of these winning science fair projects from 24 Hour Science Projects. Of course, we can’t guarantee that your project will win, but we do guarantee that you’ll be 100% satisfied with your guides.

Writing about Science Projects

guest scientistFour articles of mine have recently been posted online:

Middle School Science Projects: Finding a middle school science project that meets all these criteria has always been a challenge for our family. Our teachers wanted an experiment based, investigative project for the science fair. Middle School science teachers want creative ideas, specific elements, in depth research, and detailed logs of the whole science fair process.

Fifth Grade Science Projects that Rock: A Fifth Grade Science Project can be one of the most fun school projects that a parent and child can do together. Here are some really good science project ideas that are easy enough to do, yet meet the requirements of most science fairs and most fifth grade teachers. These are investigative science projects, which involve a science experiment.

Science Project Boards that Aren’t Boring: Kids’ science projects aren’t finished until the last letter is glued onto the science board. After the science project is finished, you want it to look its very best for the science fair! You really want the project to reflect how hard your kids have worked.

Science Fair Projects to Make Everybody Happy: Science fair projects – Kids think they should be fun. Teachers think they should be educational. Parents just want them to be fast and easy. Since students, teacher and parents are all involved in the process of getting ready for the science fair, most of the time, science projects have to be all of the above!
