Students design and create a LEGO structure that will house and protect a temperature sensor. They leave the structure in a safe spot and check the temperature regularly and chart it. After the students have built their structures, the...

Students discover which properties of solids lend themselves to building a tower through hands on trial and error and observation of others as they are building. They write down the steps it took them to build the tower and label an...

Explore osmosis through art. Learners use paper towels and markers to create beautiful designs. Although a simple activity, the results are quite remarkable. Your class will love this lesson!

A collection of ideas for creating a science fair project on the water cycle.

By comparing the feet of different water birds you can discover how they propel the birds through the water. This Science Buddies project show you how to modify swim fins to simulate ducks' feet, greebes' feet, and the feet of...

Amaze your friends and family by moving water with just a few turns of your wrist, this is known as an Archimedes screw. In this science project, you will build a very simple Archimedes screw, to transfer water from a low-lying location...

If you look carefully, you could find dozens of similar interesting phenomena that are all linked to the surface tension of water. Here is a project that will help you understand and measure the properties of water surface tension.

Have you ever wondered how a ship made of steel can float? In this project you'll investigate how much weight boat hulls of various shapes and sizes can support without sinking.

We know that plants, and even bouquets of cut flowers need water to survive, but we often do not think about how water moves within a plant. In this science project, you will use colored water and carnations to discover how water travels...

Whether a chick can breathe inside its shell is an interesting question. Every animal needs oxygen to survive, so the chick must get air somehow. Try this science project to discover if the pores in a chicken egg shell allow water to...

You know that water can exist in three separate phases: solid (ice), liquid (water), and vapor (steam). To change from one phase to another, you simply add (or remove) heat. When water boils, what happens to molecules (for example sugar...

Chances are, you have several materials around your house made of gelatinized materials. Gels are used in all kinds of products and materials: pudding, diapers, insoles, packaging, ice cream, toothpaste, and much more. In this project,...

Iron is an important mineral essential for good health. Iron deficiency can be a problem. In this science fair project, use a simple iron test kit to measure the concentration of iron in water. This experiement is explained clearly and...

Have you ever been to a tide pool during low tide? Some intertidal animals in the low tide zone are left in a tiny pool of water when the tides go out. Other intertidal animals that live in high tide zones may be left to dry out during...

Though rock candy seems to be a simple enough treat, it is also pretty interesting to make. Crystallized sugar that can be grown from a sugar-water solution is just how rock candy is made. In this experiment, you will learn to make your...

Baby Beluga may swim in the deep blue sea, but the song doesn't mention how cold it is out there. Find out in this short project how a bit of blubber can be a useful adaptation when the water is ice cold.

We all know that plants need sunlight and water to grow big and tall. But did you know that inside seeds are baby plants, and that the fragile baby plant inside the seed needs to be protected? If you've ever had a sunburn, you also know...

What is a colloid? If you have made Oobleck out of corn starch and water, then you know that a colloid is a mixture that acts like a solid and a liquid at the same time. This activity helps you determine the critical factors that...

Have you ever been swimming at the beach and gotten some water in your mouth by mistake? Then you know that the ocean is very salty. Bodies of freshwater also contain some salt, but much less compared to oceans. In this experiment you...

Water creates a lot of energy, just look at the Grand Canyon. In this science fair project, you will demonstrate the power of water by converting the kinetic energy in moving water to mechanical energy, which will lift a small weight.

In this science fair project, use a calorimeter with an attached heating element to measure how water responds to added thermal energy.

Watch out. It's Eddy Vortex, Superhero. He swirls, he tumbles, he churns up air and water. OK, maybe eddies and vortices aren't exactly superheroes, but they are powerful regions of air and water flow that you have to watch out for in...

In this environmental science fair project, students will build models of fields prepared by plow-based and no-till methods, and see which ones are best at retaining soil moisture and preventing surface runoff.

You might know that lead can be toxic, and that you can get lead poisoning from eating or inhaling old paint dust. Lead is called a heavy metal, and there are other sources of heavy metals that can be toxic, too. Silver, copper, mercury,...
