Cellphone Microscope: Turn a Phone Into a Functional Piece of Scientific Medical Equipment (Science-hack Your Phone: Part 1)

December 30, 2013 7:13 AM

Cellphones do a great job of helping us capture funny and memorable moments that we can share through our favorite social media sites, text messages, and email. That same imaging technology can be used as a tool for medical and scientific field work—or just for fun at home or in the classroom with a stack of science slides. A homemade cellphone microscope brings small things into new focus! (Plus, it's super cool to say you turned a phone into a functional microscope!) One more week of… Read more

Cornbread Science: Weekly Science Project Idea and Home Science Activity Spotlight

December 30, 2013 7:00 AM

In this week's spotlight: a food science project and family activity that explores the role of baking powder in baking. In this pair of projects, experiment to see the affect of baking powder on corn bread muffins for a clear visual look at what happens when you use more or less in your recipe. Does a light and airy muffin indicate one with or without baking powder? How does the density or weight of a muffin change in relation to the amount of baking powder used? What happens if you use… Read more

Memory Science: Weekly Science Project Idea and Home Science Activity Spotlight

December 19, 2013 10:00 AM

In this week's spotlight: a human behavior science project and family activity that explores memory and how using a mnemonic device can help you remember a string of words or the items in a list. Have you ever used the HOMES acronym to help you remember the names of the Great Lakes or ROYGBIV (or Roy G. Biv) to remember the order of the seven colors in a rainbow? In this science project, you conduct a controlled experiment to see whether or not a mnemonic device makes a difference in… Read more

Football Science: Distance and Field Goal Kicking—Increasing the Odds of Scoring

December 17, 2013 11:30 AM

Making it to the end zone on a last-second Hail Mary pass is one way to score in football, but when it's 4th and 30, a well-executed field goal for three points can be the game-tipping, winning play. What's the secret to a successful field goal? Students can put the science and math involved in one aspect of field goal kicking to the test with a sports science project that places a rubber-band catapult on the field as the team's football kicker. After seeing how your kicker does at varying… Read more

Family Robotics: Toothbrush Bots that Follow the Light

December 12, 2013 10:00 AM

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
