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

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

Does your family have jellied cranberry sauce with Thanksgiving dinner? Jellied cranberries are thick and retain the shape of the mold in which they are placed, which might mean a turkey-shaped mold or even the shape of the can if you use a canned version. Taking a bite of jiggly jellied cranberries can be a fun addition to a delicious meal, but cranberries can also be served as a liquid-like sauce. Both versions use the same ingredients, so what makes one turn into a gelatin while the other… Read more

Do you like to preserve a moment with a photo, tell a story with pictures? It can feel very rewarding to capture an experience in a compelling photo; it can also be disappointing when the photo does not convey what you were seeing or what you had in mind. You might wonder what makes some photos mesmerizing and gripping, while others look dull, empty, or unappealing. If you could only create those perfectly balanced compositions. Maybe it is easier than you think. Some easy composition rules,… 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
