Falling Objects: Weekly Science Project Idea and Home Science Activity Spotlight

Blog Post

In this week's spotlight: a pair of physics science projects that encourage families and students to put a classic question to a hands-on test. Does a heavier object fall faster than a lighter one if both are about the same size? What role do gravity and inertia have in explaining what happens when two objects of differing weights are dropped at the same time from the same height? Put it to the test!

Families and Fingerprints: Weekly Science Activity

Blog Post

Experiment to find out if fingerprint patterns are inherited or not! In this week's spotlight: a genetics and genomics family science experiment for Father's Day. Fingerprints are unique, but do family members share fingerprint characteristics? Are there patterns of inheritance that come into play when it comes to fingerprints? Put the question to the test with a visual examination of fingerprints among siblings and between different family… Read more

Family Robotics: Toothbrush Bots that Follow the Light

Blog Post

Building light-tracking robots as a family activity lets you and your kids take next steps in electronics and circuitry! My kids and I had a great time over the summer whetting our teeth on basic robotics and electronics by transforming toothbrushes into cute little Bristlebot robots that look and work very much like commercially-available nano or hex bugs. The basic Bristlebots robotics engineering project is a fun hands-on activity and one that works for a wide range of ages. You can… Read more

Fantastic Fossilization! Discover the Conditions For Creating the Best Cast Fossils

Science Fair Project Idea

Scientific Method

Have you ever stood close to a fossilized T. rex skull and counted its razor-sharp teeth? Or, have you seen a fossilized stegosaurus skeleton and thought about how it defended itself with tail spikes and armored plates? A trip to a natural history museum lets you imagine what dinosaurs looked like and wonder what life with them on Earth was like. Fossils give us information about animals and plants that lived long ago. Certain places around the world contain more fossils than others. Why?… Read more
