Chemical Analysis of Rainwater

Science Fair Project Idea

Scientific Method

Here is an interesting project that could be approached from several different scientific angles: Environmental Science, Weather & Atmosphere, Chemistry, or Plant Biology. You can probably think of your own variations to emphasize the scientific area that most interests you. Read more

Choosing the Best Gear Ratio for Maximum Bike Speed

Science Fair Project Idea

Scientific Method

Are you into cycling and speed? Then this is the science fair project for you! In this science fair project, you will determine the best gear ratio for your bike, to get the highest speed after a curve and onto a straightaway. You will learn a lot about applied mechanics and gears, all while having fun riding your bike. Read more

Do you feel like it is always too loud in your classroom? In this lesson you can find out exactly how loud it is. Using a mobile phone and a sensor app, your students will measure and graph the sound levels in your classroom for different working scenarios. How loud are your students when doing independent work, having a group discussion, or listening to their teacher? Based on your students' data, you will determine as a class which sound levels are ideal for each scenario and create a… Read more

NGSS Performance Expectations:

MS-PS4-1. Use mathematical representations to describe a simple model for waves that includes how the amplitude of a wave is related to the energy in a wave.

"Surprise Glacier" © 2010 Jiuguang Wang Do sea levels rise when ice melts? Does it matter whether the ice is on land or in the ocean? Students design an experiment to find out. They collect data, graph their results, and interpret their findings. Along the way, they learn about density, displacement, and climate change. Read more

NGSS Performance Expectations:

5-PS1-2. Measure and graph quantities to provide evidence that regardless of the type of change that occurs when heating, cooling, or mixing substances, the total weight of matter is conserved.
MS-PS1-5. Develop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved.

Climb Every Mountain with Your Own LEGO® Cable Car

Science Fair Project Idea

Engineering Design Process

If you ever rode in a cable car, ski lift, or gondola, you know they make moving over obstacles like lakes, valleys, rivers, or even up steep mountains seem easy. Though it would be pretty difficult to build a full-size cable car in your home, if you have a Mindstorms® kit, you can build a working-model cable car of your own. The engineering challenge is to build a LEGO® cable car that can travel across a string you have suspended somewhere in your house (between two pieces of… Read more

Coffee Buzz: How Does Caffeine Affect the Physiology of Animals?

Science Fair Project Idea

Scientific Method

Caffeine is a type of chemical called a stimulant. When you drink a caffeinated beverage, the caffeine enters into your blood stream dilating the capillaries and causing blood to flow more quickly. This gives your body a feeling of speeding up which can cause the jitters and wakefulness. How does caffeine affect the physiology of other animals? You can use over-the-counter caffeine supplements, like Vivarin, to test the effects of caffeine on animals. Try dissolving the caffeine in… Read more

Color Profiles

Science Fair Project Idea

Scientific Method

Did you know that the same digital photo you see on a computer monitor may not look as good in print? When it comes to color profiles, there are a lot of options: RGB, CMYK, grayscale and indexed color! How do you choose the right color profile for the job? Read more

Come One, Come All! Explore the Effect of Light on the Speed of the Amazing Rotating Radiometer!

Science Fair Project Idea

Scientific Method

Radiometers are fun-to-watch novelty items, but they also have a distinguished scientific history, having been studied by James Clerk Maxwell and Albert Einstein. A radiometer has a set of four vanes (like small sails) connected to a spindle that is free to rotate. When the radiometer is placed in bright light, the vanes and spindle start to spin. It looks like a magic trick, but there is a scientific explanation for this weird behavior. In this science fair project, you will experiment with… Read more

Compression of Wet Sand

Science Fair Project Idea

Scientific Method

Did you ever notice the cool patterns around your footprints when you take a walk in the wet sand at the beach? The pressure of your feet has effects far outside your footprints. Here's a project that uses a simple experimental apparatus to investigate how the volume of wet sand changes under pressure. Read more

Construct a Carnival Buzzer Game with a Raspberry Pi

Science Fair Project Idea

Scientific Method

Have you ever played a game that tested the steadiness of your hands? Operation® is a popular board game that requires you to perform "surgery" without bumping a tool against the edges of the game. There are also popular amusement park or carnival games where you try to move a metal loop along a wavy metal wire without letting the two touch. You can build your own version of these games using a Raspberry Pi. Check out the video to see what this simple, but fun, project looks… Read more
