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

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
