Timing the Tides

Science Fair Project Idea

Scientific Method

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 low tide. How much time does each zone spend out of water during a tidal cycle? Read more

NGSS Performance Expectations:

4-LS1-1. Construct an argument that plants and animals have internal and external structures that function to support survival, growth, behavior, and reproduction. [Clarification Statement: Examples of structures could include thorns, stems, roots, colored petals, heart, stomach, lung, brain, and skin.] [Assessment Boundary: Assessment is limited to macroscopic structures within plant and animal systems.]
4-LS1-2. Use a model to describe that animals receive different types of information through their senses, process the information in their brain, and respond to the information in different ways. [Clarification Statement: Emphasis is on systems of information transfer.] [Assessment Boundary: Assessment does not include the mechanisms by which the brain stores and recalls information or the mechanisms of how sensory receptors function.]

Want to Warm Up or Cool Down? Go Underground!

Science Fair Project Idea

Scientific Method

Have you ever been so cold sitting in your house in the winter that you feel like icicles could grow off your nose, and your feet could turn into blocks of ice? Or have you ever been so hot in your house in the summer that sweat just drips off you? Making yourself comfortable can mean turning on the heater or the air conditioner, but that costs money. Being cozy or cool does not have to cost a lot of money if you use a geothermal heat pump. In this project, you will build a model geothermal… Read more

Wave Blockers

Science Fair Project Idea

Scientific Method

What do the radio, TV, radio controlled cars, and cell phones all have in common? They all use invisible waves to transmit information. Find out which materials block radio waves, and which materials allow radio waves to pass through by doing this experiment. Read more

Weather and Climate in Your Neighborhood

Science Fair Project Idea

Scientific Method

Do you live in an area where the weather changes a lot from season to season throughout the year? Or do you live in a place where the weather stays pretty much the same all year long? How dynamic is the weather, and how does it compare to climate? In this experiment you can use the Internet to conduct your own investigation about how climate and weather in your local area change over time. Read more

What Are You Blubbering About?

Science Fair Project Idea

Scientific Method

Baby Beluga may swim in the deep blue sea, but the song does not mention how cold it is out there! Find out in this science project how a bit of blubber can be a useful adaptation when the water is ice cold. Brrrr! Read more

Where Did All the Stars Go?

Science Fair Project Idea

Scientific Method

One of my favorite things to do when I was a kid was to go outside and look at the stars. As an adult, I moved to a major city and the stars seemed to vanish from the sky. Where did they go? Read more

Where Do Earthworms Hang Out When Food Is Around?

Science Fair Project Idea

Scientific Method

Earthworms are important for the soil and fun to study. In this science project, you will find where earthworms like to stay when food is around. Will they gather around the food, take food with them in their tunnels, or not be attracted to the food at all? You will fill four pots with dirt, add food and worms, and track their activity over one week to find out! Read more

Who Has the Biggest Genome?

Science Fair Project Idea

Scientific Method

Humans are complex creatures, but do we have the biggest genome? All living things, from humans to worms to bacteria have genomes. In this experiment you will compare the genome sizes of different organisms to find out who has the smallest and the largest genomes. Where will we fit in? Read more

Have you ever noticed that the dried fruits or nuts in your breakfast cereal are not evenly spread out inside the box, or that in a container of mixed nuts Brazil nuts gather at the top? This phenomenon is commonly called the "Brazil nut effect," and the science behind it is surprisingly complex and far-reaching. This phenomenon can be a nuisance when you want to fill silos, bags, or bins with different types of materials. It can also be used to our advantage: an avalanche airbag uses the… Read more
