Cha-cha-cha by Latitude

Science Fair Project Idea

Scientific Method

You probably know that where you live on Earth affects your weather. If you live in a far northern or far southern latitude, you experience colder temperatures than people who live near the equator at latitudes close to zero. Your latitude on Earth affects many aspects of your culture, like how you dress, what kind of house you live in, what foods you eat, and even how your day is structured: what time you go to school, to dinner, and to sleep. Some cities at latitudes closer to the equator,… Read more

Chain Reaction: Inversion and the Pappus Chain Theorem

Science Fair Project Idea

Scientific Method

Here is a challenging problem for anyone with an interest in geometry. This project requires background research to solve it, but it is an excellent illustration of visual thinking in mathematics. Figure 1 below shows a series of circles (iC₁, iC₂, iC₃, ..., iC₃₀), inscribed inside an arbelos. What is an arbelos? The arbelos is the white region in the figure, bounded by three semicircles. The diameters of the three semicircles are all on the same line segment, AC,… 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

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

Colorful Walking Water Science Activity

Blog Post

This simple STEM activity turns capillary action and "siphoning" into an exciting rainbow-colored demonstration! Try this colorful "Walking Water" science activity How can you move water from one cup to another without pouring it? A simple hands-on experiment with a series of clear cups and paper towels lets students explore this question. When they see water move up and then down the paper towels, there will be plenty of opportunity for… Read more
