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
Clean Water and Aquifer Science
Blog Post
Is rainwater that seeps into the ground and passes through layers of soil clean or dirty? In this week's family science spotlight, kids explore how the passage of water through underground layers can result in storages of groundwater that are surprisingly clean! Above: students can explore aquifers and filtration with simulated "dirty water" and model collection bins. Natural Water Filtering In this week's family-friendly science activity, students experiment to see how the process of… 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
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
Collide Head On with this Toy
STEM Activity
Did it ever occur to you that tennis, bowling, Newton’s cradle, and cars bumping into each other all revolve around collisions? It is fascinating how a few rules of physics can predict the outcome of these collisions. You can discover these rules yourself with a fun homemade toy. Do the activity, play with the toys you make and be one step closer to understanding what happens when you shoot a marble into another! Read more
Color Mixing and Family Physics
Blog Post
Put on a colorful nighttime light show with this family STEM experiment! With inexpensive flashlights and colored cellophane papers, kids can experiment with additive color mixing. The results might surprise you! Mixing Colors From the time they are little, most kids learn about color mixing. In craft and art projects using colorful crayons, markers, and paint, kids are encouraged to explore how primary colors can be combined to make secondary and tertiary colors. In this week's… 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
Science Fair Project Idea
Scientific Method
Lively, vivid colors can add pizzazz and turn a dull photo into a work of art. Learn how changing the saturation levels of the colors in your photo can really make it pop! Read more
