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.

Make a Medical Alert Fall Detector

Science Fair Project Idea

Engineering Design Process

Have you ever wondered what someone would do if they fell, got hurt, and could not get up on their own? What if they were home alone and could not reach a phone to call for help? Or, what if they lost consciousness - is there any way to automatically detect that they fell and needed help? In this project, you will program your own fall detector, a device that can automatically detect when someone has fallen over, then sound an alarm or even send a message to someone else. Devices like these are… Read more

Make a Model Rocket Land Vertically

Science Fair Project Idea

Engineering Design Process

Companies like SpaceX and Blue Origin are dramatically lowering the cost of space flight by designing reusable rocket boosters that land back on Earth. Getting a rocket to land vertically without any damage - and without using a parachute to slow it down - is quite a tricky physics problem! In this project you will modify your own model rocket so it can land vertically. Read more

Make a Pomodoro Study Clock

Science Fair Project Idea

Engineering Design Process

The Pomodoro technique is a popular study method consisting of alternating study sessions and breaks. In this engineering project you will build your own customized Pomodoro timer or clock using an Arduino. In addition to displaying the time, you can use your clock to display messages or get the user's attention using lights, sound, or even moving parts. Can you work more efficiently with a Pomodoro timer at your side? Build one and find out! Read more

Make Your Own Piezoelectric Pickup for Acoustic Guitar

Science Fair Project Idea

Scientific Method

In this project you'll learn how to make a piezoelectric pickup for acoustic guitar using inexpensive components. You can then connect your acoustic guitar to an amplifier, and record your own music. If you are interested in electronics and like playing acoustic guitar, this could be the perfect project for you. 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

Make Your Own Wireless Alarm System

Science Fair Project Idea

Engineering Design Process

Have you ever wished you could have an alarm to prevent your little brother or sister from sneaking into your room? How about an alarm to prevent someone from stealing your favorite toy or from taking cookies out of the cookie jar? In this project you will learn how to program your own customized, wireless alarm systems to send you alerts about whatever you want! Read more
