Showing Results for ocean

4th graders construct an ocean food web to learn about consumers and trophic levels, food webs, and food chains in this cool ecology science fair project.

This science fair project idea demonstrates sonar mapping of the ocean floor.

Why doesn't the ocean freeze? Students answer this question by simulating the chemical composition and temperature of arctic waters in their own home.

Science fair project which simulates the global conveyor belts on a small scale, and observes the effects of wind, density and temperature on water movement.

This science fair project examines whether ocean water can be made safe to drink.

In this experiment, you'll make a seafloor spreading model to learn more about how plate tectonics work and create mid-ocean ridges.

In this project, you'll build a model of the earth, complete with all seven continents and four major oceans.

You've heard all about oil spills, but can they really be that bad? After all, vegetable oil is in almost every yummy baking good from cookies to brownies.

Science fair project that explores the natural process of limestone formation.

This science fair project idea compares biodiversity between drops of water.

This science fair project idea investigates how a bottom keel helps keep a boat from rocking back and forth.

This science fair project examines how tsunamis travel by simulating a tsunami moving around an island. You will generate a pretend tsunami in a swimming pool.

How does water pressure change with depth? Kids learn how pressure works underwater with this cool and easy demo.

This science fair project idea uses the process of chemical weathering to change a mineral.

Will increasing the amount of salt in water effect how slow or fast the water freezes?

This science fair project idea models industrial oil spills and determines if they have an impact on wildlife living beneath the surface of the water.

In this experiment we use Scotch Guard to make sand that resists water.

Examine the influence of the phase of the moon on moisture capillarity in garden soil. Measure and record the depth at which water is first detected.

How do animals keep warm? In this experiment, find out whether fat insulation resists cold temperatures and learn how this works in the animal kingdom.

What heats up fasterâwater or soil? 5th grade students test the specific heat of water against the specific heat of sand in this great science fair project.

Using an empty tennis ball can and a swimming pool, you will determine if it's possible to have a conversation under water.

This science fair project will help learners determine whether algae can be made to grow by feeding it supplementary carbon dioxide.

This project examines the concentration of dissolved oxygen in water, with and without oil.

This experiment will explore the possibility of a connection between lunar cycles and how humans are affected.

Brine shrimp usually live in saltwater. Investigate how salt concentration (salinity) affects the rate at which brine shrimp eggs hatch.

Determine how salinity affects the circulation of warm and cold water. Note whether the warm water mixes or forms a layer with cold water.

Science fair project about different digital image file types, compares different encoding algorithms used to compress the data.

Free science fair project idea examining how different types of water affect plant germination and growth.

In this free science fair project, learn how to separate salt from water using heat. A great science project for elementary school kids.

In this science fair project, students will create a model of a shoreline, observe erosion and examine how jetties prevent erosion.
