It might seem impossible to estimate how many different bugs live in a nearby field, or how many types of birds live in a forest, but wildlife biologists often have to try to determine the number of different species in a given habitat. This plays an important role in helping us understand how healthy the environment is. In this activity, you will get to take on the role of a wildlife biologist by examining the biodiversity of bugs and other small invertebrates (such as spiders, centipedes,… Read more

Summer is the perfect time to take a stroll at the beach and walk barefoot along the shoreline. While doing that, have you ever looked at your footprints in the wet sand? If so, you might have noticed that with every step it looks like the sand around your feet dries out. Why is that? These dry footprints are caused by the pressure of your feet. You will find out exactly how this happens by doing this beachy activity! Read more

Exploring Nanotechnology: Fold, Roll, & Stack Your Way to Super-Strong Materials

Science Fair Project Idea

Scientific Method

Advertisements for high-tech sports gear or the latest and greatest outdoor material promise lighter and stronger products every season. Is it a scam? How can engineers keep creating materials that are both lighter and stronger than anything known so far? The answer is in the nanoscale! Using nanotechnology, scientists can play around with the detailed structure of matter, leading to a whole new range of materials, some with amazing qualities. In this science project, you will get a glimpse… Read more

Exploring the Uncanny Valley

Science Fair Project Idea

Scientific Method

What do you consider creepy? Clowns? Zombies? Video game characters with jerky movement? In 1970, a roboticist by the name of Masahiro Mori suggested that people are "creeped out" by robots that are almost, but not exactly, humanlike. He called this phenomena the uncanny valley. But researchers are still exploring and defining the uncanny valley. In this science project, you can do your own exploration—just try not to creep your friends out too badly! Read more

Field Goal! The Science Behind a Perfect Football Kick

Science Fair Project Idea

Scientific Method

Did you know that throwing, kicking, and punting a football all involve the science of projectile motion? A star NFL® quarterback, kicker, and punter each need to have a very good understanding of how a football moves through the air in order to help them win games. In this science project, you will set up a rubber band-powered catapult to represent a field goal kicker, and study how changing the distance from the goalposts affects how hard it is to accurately kick a field goal.

Fighting the Flu: How Your Immune System Uses Its Memory

Science Fair Project Idea

Scientific Method

Being sick is no fun, especially when your friends are doing exciting activities that you have to miss out on. Thankfully, common illnesses usually last for just a few days, and then you start to feel better. Why is this? It is thanks to the immune system, which is a group of special organs and cells in your body that constantly work to keep you healthy. In this science project, you will make a simple model to investigate how the immune system defends the human body from common illnesses, and… Read more

Find the Horsepower of a Toy Car

Science Fair Project Idea

Scientific Method

Have you ever heard someone describe how much horsepower a car has? Why do we use horses to measure how powerful cars are? What exactly is horsepower? How is horsepower related to things like speed and torque? Find out in this fun science project as you use a simple setup to find the horsepower of a battery-operated toy car. Read more

NGSS Performance Expectations:

3-LS1-1. Develop models to describe that organisms have unique and diverse life cycles but all have in common birth, growth, reproduction, and death.
4-LS1-1. Construct an argument that plants and animals have internal and external structures that function to support survival, growth, behavior, and reproduction.
MS-LS1-4. Use argument based on empirical evidence and scientific reasoning to support an explanation for how characteristic animal behaviors and specialized plant structures affect the probability of successful reproduction of animals and plants, respectively.
