Mathematicians look at the world around them in terms of numbers and formulas, and now, you can discover the formula for Pi too! In this science activity you will examine circular objects and see what you can discover about their sizes. As you explore, you might be surprised at how useful the results can be—maybe it will inspire you to save up for a bike with bigger wheels! Read more

Coastal and Marine Geology

Science Fair Project Idea

Scientific Method

You can study hazards that affect coastal areas. What geological forces cause a tsunami? A tsunami (Japanese for 'harbor wave') is a wave generated by an undersea earthquake, landslip, or volcanic eruption. You can demonstrate what causes a tsunami by simulating an undersea earthquake with a water table. How does the depth of water effect the height of the wave? Do different slopes of bottom change the speed of the wave? Visit the USGS Coastal and Marine Geology Program to find out about… Read more

Color Mixing with Red, Green, & Blue LEDs

Science Fair Project Idea

Scientific Method

This is a good project for someone who is interested in both electronics and color vision. The equipment needed is on the expensive side, but if you continue studying electronics, you can use it again and again. Read more

Color Saturation

Colorizing Images from the James Webb Space Telescope

Science Fair Project Idea

Engineering Design Process

The James Webb Space Telescope (JWST) has shown us some amazing images of space, like its first "deep field" image (Figure 1). The JWST sees the universe in the infrared part of the electromagnet spectrum, which is not visible to the human eye. How, then, does it produce color images like the one in Figure 1? Scientists must colorize the images, or apply "false color." They map different bands of the infrared spectrum to colors of visible light, resulting in an image humans can view. Luckily,… Read more

Compare Circumference and Diameter with String

Blog Post

Things that are circular in shape surround us. From quarters to wheels to the openings of cups and bottles, circles are abundant, and they come in all sizes. In this week's family science activity, students explore properties of a circle, just like mathematicians do, to see if they can identify the relationship between the diameter of a circle and the circumference. This hands-on math activity turns these measurements (and the concept of Pi) into something that can be visualized with… Read more

Comparing Vocal Ranges: How High and Low Can Your Voice Go?

Science Fair Project Idea

Scientific Method

What is the highest note you can sing? How about the lowest? Do you think males and females can reach the same notes? How about children and adults? Find out the answers to all these questions in this "note"-worthy science fair project! Read more

Compost Creativity: Try Various Methods and Test Soil Fertility

Science Fair Project Idea

Scientific Method

Make your own fertile soil using kitchen scraps, manure, leaves, grass clippings, and other compostable materials. Which materials make the best compost? How does the amount of nitrogen change the rate at which the compost forms? How does a 'hot' compost pile compare to a 'cold' compost pile, or how does traditional composting compare to worm composting, or vermiculture? Figure 1. Different composting methods yield different soils. In this picture, the soil on… Read more
