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.]

Understand Shock Levels and Packaging Principles

Science Fair Project Idea

Scientific Method

When you open up your presents on your birthday, you probably don't spend a lot of time admiring the wrapping—you'd much rather see what's inside. It can be the same way with the packaging that products come in, but packaging is important for protecting the things we buy as they make their way from the factory to our homes. How much shock force is produced when a box gets dropped accidentally? What kinds of materials work best to protect products from damage? This project can show you… Read more

Veggie Snap! Modifying Bending Stresses in a Flexible Rod

Science Fair Project Idea

Scientific Method

Have you ever broken a fishing rod? Or seen a treetop bend over and touch the ground (or even snap off) during an ice storm? These are examples of the effect of bending stresses on flexible rods. There are scientists who actually study this phenomenon and discover ways to prevent breakage, which leads to stronger fishing rods, building materials, car parts, and more. In this science project, you'll explore the bending stresses in flexible rods by testing asparagus stalks. Read more

Volleyball Machine Challenge for Grades 3-5

Lesson Plan Grade: 3rd-5th

Teach your students about the engineering design process with this fun lesson plan. They will design and build two "volleyball machines" that launch a ping pong ball back and forth over a net. While the 2019 Engineering Challenge is over, your students can still try this project and compare their scores to top scores from around the world! Teachers, note that middle school and high school versions of this lesson plan are also available. Looking for this year's challenge? Check out our… Read more

NGSS Performance Expectations:

3-5-ETS1-3. Plan and carry out fair tests in which variables are controlled and failure points are considered to identify aspects of a model or prototype that can be improved.

Watch Out! That Wild Animal Might Be Rabid!

Science Fair Project Idea

Scientific Method

The word rabid often makes people think of an animal that is extremely violent, crazy, and maybe even foaming at the mouth. But not all animals infected with the rabies disease fit that description. Nevertheless, it is important to avoid animals that have rabies so that you don't get infected. So which wild animals are likely to carry rabies? This science fair project will help you discover the answer! 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

Wind is a part of our everyday weather. Its strength can range from a soft breeze to a violent storm. In this lesson, students learn how to measure wind speed by building anemometers (wind speed meters) from paper cups and straws and experimenting with them. Read more

NGSS Performance Expectations:

3-ESS2-1. Represent data in tables and graphical displays to describe typical weather conditions expected during a particular season.

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
