Does your hair go frizzy during "April showers," when the weather turns damp? Strands of hair can relax and lengthen when the humidity (or the amount of water vapor in the air) increases, and then contract again when the humidity decreases. In fact, the rate of change in the length of hair strands is so dependable that they can actually be used as the basis for a hygrometer, a device that measures the humidity level in the air.

Get creative with your students in this hands-on lesson plan! Students will use mostly natural materials to build a shoebox habitat that mimics a real-life habitat for an animal of their choice. As they present their miniature habitats to each other, students realize that not all habitats are suitable for all animals. Each animal species needs the resources of a specific habitat to survive.

You might know that sound is caused by vibrations, but did you know that sound can also make things vibrate? You might have noticed this if you have ever been at a concert or in a car with the stereo booming. Sometimes the sounds are so loud that you can feel the vibrations! However, sounds that loud can damage your hearing, so in this project you will investigate them using something safer. Read more

Make Your Own Stethoscope

Science Fair Project Idea

Scientific Method

Doctors use many complicated tools to check the health of patients. But you can make some medical tools at home—like a stethoscope! A doctor uses a stethoscope to listen to a patient's heart. In this science project, you will make three of your own homemade stethoscopes and figure out which stethoscope design works best and why. Read more

Have you ever blown across a bottle's top and made a pleasant, resonant sound? If so, have you wondered how that note is made exactly? The exact note you hear depends on the resonant frequency of the air in the bottle. Musical instruments like ocarinas operate based on a similar principle. In this science activity, you will use bottles to investigate how the volume of the air in the bottle affects the pitch of the note that it makes. Read more

Save Those Spoiling Strawberries!

Your students might know that plants need water to survive. But how does a plant "drink" and get water from the soil all the way up to its' leaves? In this lesson plan, students will observe how plants (flowers and celery) suck up dye-stained water, which makes the petals and leaves change color! This allows students to visualize the process of how water moves through a plant. Read more

NGSS Performance Expectations:

2-LS2-1. Plan and conduct an investigation to determine if plants need sunlight and water to grow.

A Solar-Powered Robot Bug

Science Fair Project Idea

Scientific Method

"How do you frighten a grasshopper? And what does that have to do with light?" These are a couple of questions you're probably asking yourself after reading the title. Well, The Frightened Grasshopper Solar-Powered Bug is actually a toy grasshopper that vibrates when it is placed in sunlight or near a lightbulb. It stores up the energy from light, and converts it into motion. You will use this fun toy to explore how the brightness of the light affects the motion of the solar-powered insect. Read more
