How many ball sports can you name? How many of those have several balls at once in the game? Almost none, right? Games that do use several balls at a time most likely use balls of the same mass, volume, and material. Would having two balls of a different mass make a game very difficult? In this activity, you will explore what might happen if you were to add a tennis ball to a basketball game, or a tiny ping pong ball to a tennis game, or any other combination. Ready to be surprised? Try it out! 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

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 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

Exploring Bridge Beams with Spaghetti

Blog Post

How do engineers ensure that bridges and other structures can support weight properly so that they don't collapse? In this week's materials science-themed family science activity, families can use uncooked spaghetti noodles to explore the forces that come into play when weight is applied to a beam. What happens when the spaghetti bends in response to weight? If the noodles break, where do they break? Was the breakage the result of compression or tension? Does using more pieces of… Read more

Exploring Surface Tension: Doing Fun Science at Home during School Closures (Activity #18)

Blog Post

Follow along with a Science Buddies parent who is using family STEM activities to keep her kids learning at home during the COVID-19 school shutdown. New posts every Monday, Wednesday, and Friday. Today's adventure... exploring surface tension by making wire water striders. A Spill Leads to Exploring Surface Tension What happens when you put a freshly laundered tablecloth on the table? Well, in my house, it immediately triples the chance that someone… Read more

Factors that Affect the Transfer of Force through Saturated Soil

Science Fair Project Idea

Scientific Method

Soil liquefaction is a phenomenon where soil that is saturated with water suddenly loses its strength and behaves like a liquid. This usually occurs due to sudden, large stresses on the soil — for example, from an earthquake. This can be very dangerous for buildings sitting on top of the soil, as they can suddenly sink into the ground! The embedded video explains soil liquefaction in more detail. Is there a way to prevent soil liquefaction? Do you think adding certain materials to… Read more
