Static Electricity Science: Weekly Science Project Idea and Home Science Activity Spotlight

Blog Post

In this week's spotlight: an electricity project and family activity that takes the zap out of static electricity. What causes the buildup of static electricity and may cause you to get "shocked" when wearing, rubbing up against, or touching certain materials or objects? What does what the object is made of have to do with static electricity? In this project, you and your family can build a cool tool, an electroscope, to detect electric charges and test to see how different materials… Read more

Have you ever helped your parents cook a pot of spaghetti? Strands of spaghetti are pretty long, so sometimes people break them in half so they fit into the pot more easily. How exactly does the spaghetti break? And what does this have to do with science? It turns out engineers and materials scientists study how materials break when they are bent. While professional engineers might be more concerned with steel beams in a bridge, you can still do a fun experiment with some pasta in your kitchen. Read more

Strength of an Egg: Weekly Science Project Idea and Home Science Activity Spotlight

Blog Post

In this week's spotlight: a materials science family experiment and science fair project that asks you to rethink what you know about eggs. Are they fragile? Or are they strong? If you've ever accidentally stuck your finger through one in the kitchen, you may think you know the answer! But the shape of an egg can support a surprising amount of mass. It is a shape, in fact, that can be found in architecture. How much mass can eggshells hold? Put it to the test with a… Read more

Have you ever noticed that some objects tend to expand when they get hot, and contract when they cool down? For example, you might run hot water over the lid of a jar that's stuck - this causes the lid to expand, making it easier to twist off. Does this effect work the same way for all materials? Try this fun activity to find out! Read more

Balloons are fun and come in a variety of sizes, colors, and forms that makes them well suited for decorations, water play, modeling, and other creative activities. But balloons also have uses outside of recreation; weather balloons, balloons used to widen obstructed arteries, and balloons that provide transportation are just a few examples. The first balloons were made of animal bladders or intestines. This made way for the latex, rubber, and nylon fabric balloons we see today. Have you ever… Read more

Stretchy Dough and the Science of Gluten

Blog Post

In this family STEM activity, students mix up dough in the kitchen to explore the role of gluten in making doughs stretchy and elastic. The Science of Dough Preparing many baked goods involves first mixing up a dough that is then kneaded (or not kneaded), left to sit for a certain amount of time (or not), and stretched or rolled during the process (like a pizza crust) before it is baked. Depending on the desired texture of the dough and the ingredients used, the steps of the recipe will… Read more

Study Chirality with a Homemade Polarimeter

Science Fair Project Idea

Scientific Method

Some molecules can be either left- or right-"handed." The left- and right-handed molecules have the same number and type of atoms, and their chemical structures look identical, but they are actually mirror images of each other. Many naturally occurring molecules have this property, called chirality. Chiral molecules can interact with polarized light in an interesting way—they rotate the plane of polarization. This chemistry science fair project describes how to make a homemade polarimeter… Read more

Superbugs and Antibiotics: Explore with a Dice Game

Blog Post

Stopping the course of an antibiotic early is one way that bacteria develop greater resistance to available medicines. A new classroom activity, sponsored by Cubist Pharmaceuticals, helps students see how populations of bacteria respond to antibiotics. Using a colorful dice game, students roll the dice to see how many bacteria respond to treatment each day. How much harder is it to kill off a superbug? At the end of the game, the students can tell by looking at the dice that… Read more

Sustainable Construction: Building with Mushroom Roots

Science Fair Project Idea

Scientific Method

Does growing your own house sound futuristic? If so, this project might surprise you! An overlap of biology, material science, and environmental science has resulted in some intriguing self-assembling materials. In this project, you will grow one of these materials: mycelium composite. It is made of agricultural waste and mushroom roots. You will explore two ways to grow your own construction material. Try it out and see which method proves to be the strongest! Read more
