Sliding and Friction: Weekly Science Activity

Blog Post

In this week's spotlight: a fun physics activity that turns exploring the relationship between friction and sliding into a cool hands-on exercise. With a rubber band and a stack of coins, families can slingshot the coins on various surfaces to see how the surface affects how the coins slide. This science activity may feel like a game, but there is great science to be observed, so grab a rubber band, make a finger-based slingshot, and let the coins slide! Effect of Friction on… Read more

Slinking Slinkies

Science Fair Project Idea

Scientific Method

Want to do a project with a toy your parents, or even grandparents, might have played with? Slinkies are fun toys that also make great physics and engineering projects. In this science project you will investigate how changing the angle of an inclined plane affects how the Slinky walks down it. What angle will enable the Slinky to go for the best walk? Read more

Have you ever seen a real virus? Probably not—they are so tiny that it is impossible to see them with your naked eyes. But how big or small are viruses really? The coronavirus Sars-Cov-2, which causes COVID-19, is about 120 nanometers in size. One nanometer is equal to one billionth of a meter! How many of these tiny coronaviruses do you think can you line up inside a pencil dot? In this activity, you will find out by creating a scale model that allows you to compare the size of many… Read more

Sniffing Out the Science of Smell

Blog Post

These science projects help students explore smell-based questions related to human biology and food science. Sometimes, great science is right there at the tip of your nose. Like taste, how intensely or how accurately we smell things around us varies from person to person. You may even find that your sense of smell is stronger at certain times than others. Are you the first in your house to pick up the smell of a skunk in the area? Do you walk into… Read more

Soil and Earthquakes

Science Fair Project Idea

Scientific Method

Is soil structure an important factor in earthquake dynamics? Investigate soil liquefaction and how different soil types respond to earthquake movements. Are movements more dramatic in sandy/loamy or clay type soils? Which soil structures are most stable? Which are the most volatile? (MCEER, 2005) Read more

Solar Speedway

Science Fair Project Idea

Scientific Method

Solar power is hot these days. Gleaming, black solar panels soak up rays on more and more rooftops of homes and businesses providing a clean, alternative source of heat and electricity. You might guess that different times of the day yield different levels of solar power. But just how much does the sun's position in the sky affect the power that solar cells and panels can generate? That's the question this project is all about. Read more

Solid Ground? Measuring Soil Bearing Capacity

Science Fair Project Idea

Scientific Method

Foundations for many types of structures rest on soil. This project shows how you can investigate the bearing capacity of different types of soil. Read more

Something's Fishy About That Fertilizer

Science Fair Project Idea

Scientific Method

Did you know that when you use fertilizer in your garden, it can eventually reach a lake, stream, or pond? There are many different chemicals present in fertilizers. How will they affect the aquatic organisms in the ecosystem? In this science project you will get to find out! Read more

Have you ever seen news coverage or other pictures of an oil spill in the ocean and wondered how all of that oil could be cleaned up? Oil spills can devastate wildlife by covering them with oil, and they can damage our precious water resources by contaminating them with oil. Part of the problem of managing oil spills is that the oil can be challenging to clean up. In this science activity, you can test the absorptivity of different materials (called sorbents) to discover which ones are best at… Read more

Sorting Out Sedimentation

Science Fair Project Idea

Scientific Method

Sedimentary rock forms in layers that are deposited one after the other over long periods of time. Oftentimes, sedimentary rock contains fossils and other debris that are deposited within the layers. How do sediments form? How are sediments of different shapes, sizes, and types sorted during the process of sedimentation? Find out in this science fair project! Read more
