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 Perceptrons: A Simple Type of Neural Network
Science Fair Project Idea
Engineering Design Process
Have the phrases "machine learning" or "neural network" caught your interest, but you are not really sure how to use them in a science project? This project is a great place to start for beginners. You will learn about a very simple type of neural network—a computer program modeled after the human brain—called a perceptron. The perceptron can make a simple yes/no decision based on several inputs. You can "train" your perceptron to improve its decision-making abilities. Try it and… 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
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
Expression Cloning
Science Fair Project Idea
Scientific Method
What is expression cloning and how is it used in the biotechnology industry? How are plasmids constructed for use in a bacterial expression system? You can investigate these questions and more using bacterial expression kits meant for high school classes. You will need a laboratory space equipped to grow bacteria and carry out simple molecular biology. A kit with plasmids and bacterial cells to transform are also needed. Here are two possibilities: BioBuilder What a Colorful World Kit … Read more
