Enjoy It Now... Or Enjoy It Later? Understanding Delayed Gratification
Science Fair Project Idea
Scientific Method
Have you ever thought to yourself, "I have got to have that new video game right now?" Or maybe there's a new shirt at the store that you just have to have. So you rush home, break into your bank, and gather all of your money, even though you have been saving to buy your mom a gift. But wait! Maybe if you do a few more chores and save for just a few more days, you can gather enough money to buy your mom a gift and buy what you want. This behavior is called delayed gratification and it's what… Read more
Estimation and Population Size
Science Fair Project Idea
Scientific Method
Have you ever wanted to take a short cut? How about when doing your math homework? In this experiment you can learn how estimation can save you time doing math calculations. But beware, some estimations are better than others! Can you match this sample size with the best population? How accurate are your estimation skills? Read more
Expanding and Contracting Gases: Weekly Science Activity
Blog Post
In this week's spotlight: a chemistry family science experiment that guides students and families in an exploration of how gases behave, especially when they are cooled or heated. Many gases are invisible, but they are everywhere around us. By trapping gas in a balloon, you can investigate how the kinetic energy of a gas changes in response to temperature and how the change in the motion of the gas molecules makes the balloon shrink or expand. With some hands-on measurements, a bit of air… Read more
Explore Diabetes with Student STEM Projects
Blog Post
November is National Diabetes Awareness Month. Students interested in science related to diabetes can learn more with hands-on science projects and activities. Exploring Science Questions Related to Diabetes When faced with a science project or science fair project assignment, students who have Type 1 Diabetes, or have a family member of friend with diabetes, often immediately think about exploring a science question related to diabetes. Diabetes… Read more
Explore Interplanetary Spacecraft Maneuvers with FreeFlyer®
Science Fair Project Idea
Scientific Method
If you are interested in space travel and willing to do some coding, this project is for you! It uses FreeFlyer®—powerful software that allows you to simulate space travel—to explore essential mission questions. Space travel is complex. Many factors influence the trajectory of a spacecraft. Simulations like the ones generated by FreeFlyer are powerful, as they allow you to analyze each factor in isolation, and then visualize the effects in various ways. Once you familiarize… Read more
Explore Magnification with a Drop of Water: Weekly Science Spotlight
Blog Post
What happens when you look through water at something below it? Does the object (or image) appear larger? Does it appear smaller? How much larger or smaller? It may depend on the shape of the water. Viewing something through a drop of water may make the object or image appear larger. Viewing through a layer of water in a container like a cup, on the other hand, may have a different effect because the curvature of the water is different. (The size of the drop of water may also make a… Read more
Explore Nanotechnology with Paper: Weekly Science Activity
Blog Post
In this week's spotlight: a materials science activity that gives families a hands-on look at nanotechnology. Materials coming out of nanotechnology research are often lighter and stronger than traditional materials. Nanotechnology scientists are working with matter at the nanoscale, which means they are working with individual atoms and molecules. By altering the structure and arrangement of particles, scientists are creating and discovering new materials that have exciting new… Read more
Explore Radioactive Decay with Coins
Blog Post
Explore the science of radioactive decay with a safe hands-on family STEM activity. As radioactive materials decay, or break down, they emit radiation that may be harmful. Unfortunately, the amount of time it takes for a radioactive material to decay varies. Scientists talk about the rate of decay in terms of the material's "half-life." Some materials have a very short half-life and others have a very long half-life. In this week's family science activity, students can simulate… Read more
Explore Satellites with Powerful Simulation Software
Science Fair Project Idea
Scientific Method
The first man-made satellite, the Sputnik 1, was launched in 1957. As of late 2020, more than 2,600 man-made satellites orbit Earth, with a little over 70% of them in low Earth orbit. If you would like to delve into how satellites and their sensors are configured, or into how their orbits are planned—and do not shy away from a little programming—this project is for you! With the help of FreeFlyer®—powerful software that allows you to simulate satellite orbit and… Read more
Explore the Science Behind Self-Driving Cars
Blog Post
Use these free STEM lessons and activities to help K-12 students think about and experiment with designing and training self-driving cars and autonomous vehicles. Teach About Self-Driving Cars Once thought of as something only in science fiction or the future, technologies that support self-driving cars and autonomous vehicles are in development. While fully autonomous vehicles are not yet mainstream, the number of cars being produced with… Read more
