Species Science: Weekly Science Project Idea and Home Science Activity Spotlight

Blog Post

In this week's spotlight: a pair of science projects for buggy, backyard exploration. What does it mean for an area to be have a lot of biodiversity? Why is this important to the health of an ecosystem? How do scientists measure biodiversity? You can explore by doing a study of the biodiversity of insects in your own backyard using a homemade bug collector. This week's hands-on science project and activity guide either an independent project or a family investigation. How many types of… Read more

Sprouting Sweet Potatoes Slips

Science Fair Project Idea

Scientific Method

Have you ever enjoyed eating a tasty sweet potato? They can be served as yummy mashed sweet potatoes with melted butter, turned into golden-brown sweet potato fries, or prepared in many other scrumptious ways. Did you know that you can make a sweet potato grow into a sweet potato plant, and grow several sweet potatoes this way? In this science project, you will grow your own sweet potato plants and investigate what part of the sweet potatoes is needed to grow the plants. Read more

Stop Slumping: What Makes Foams Stand Up Straight

Science Fair Project Idea

Scientific Method

Here's a riddle for you: What would a latté be without a froth of bubbly milk on top? Answer: Black coffee! And how about a pumpkin pie without the whipped cream? Answer: Sad. Delicious, edible foams are everywhere, from sodas, meringues, and soufflés to mousses and whipped creams. They provide a delicious, spongy contrast to the foods they accompany, and their airiness releases aromas that enhance the eating experience. So, what makes a good foam? One with high volume and lots of… Read more

Study Bottle Rocket Performance with Electronic Sensors

Science Fair Project Idea

Scientific Method

Rocket design and operation is a fascinating field and analyzing the flight path provides insight into the rocket's performance. In this project, you will take measurements of the flight path to evaluate how a change in the rocket design or launch procedure impacts the rocket's performance. Initially, while the bottle rocket expels water (or the rocket expels exhaust), the rocket gets a boost. This push is referred to as thrust and projects the rocket forward. Earth's gravity pulls the rocket… Read more

Sweaty Science: Weekly Science Project Idea and Home Science Activity Spotlight

Blog Post

In this week's spotlight: a sports science project and family activity that lets you experiment to find out how different activities affect your heart rate. Exercise is important, but do all forms of exercise make your heart work the same? Does your heart work as hard when you are walking as it does when you are jumping on a trampoline or playing a game of basketball? Which activities and exercises really get your heart going? What does it feel like when your heart starts working harder?… Read more

Talk About a Bad Hair Day!

Science Fair Project Idea

Scientific Method

Did you know that you can make a simple hygrometer (a device for measuring the relative humidity of the air) with hair? Search online for instructions to build one. Does the type of hair used in the hygrometer affect the accuracy of the results? Do some types of hair respond faster than others? Do some types of hair give a larger (or smaller) response? You could get hair samples from classmates, or a local beauty shop. Use hair samples of equal length to construct each hygrometer. To force… Read more

Test and Change the Air Quality of Your Environment

Science Fair Project Idea

Scientific Method

Do you ever wonder if the air inside is cleaner or dirtier than the air you breathe outside? In this science experiment, you will test it using an air quality monitor. Have you ever wondered how lighting a candle in your room impacts your air quality? Did you cook and not turn on the fan? How did it affect your breathing, and how did it impact the air quality? In this project, you can see how these environmental factors can improve or worsen the air you breathe every day. Read more

Test the Webb Space Telescope's Amazing Multiple Mirrors and Sunshield

Science Fair Project Idea

Scientific Method

Can you imagine designing and building a space telescope the size of a tennis court? Believe it or not, that is someone's job! Hundreds of engineers were involved in getting the James Webb Space Telescope (JWST) into space. This telescope has the potential to enable astronomers to see light from when the Universe was first formed. No one knows what amazing discoveries this might lead to, but already, JWST has delivered astounding deep space images that offer an unprecedented look at… Read more
