Kindergarten Science Experiments (Page 87)

Science Fair Project Idea

Scientific Method

Does listening to classical music help or hinder concentration and performance on cognitive tasks? You'll need help from a teacher to design two short, age-appropriate worksheet tests for this experiment. The tests should be of equal difficulty. You'll also need the cooperation of several additional classroom teachers in order to test enough students (at least 50-100, see the Science Buddies resource: How Many Participants Do I Need?). Half the students will take test A while listening to… Read more

Classify Spam Emails with Natural Language Processing

Science Fair Project Idea

Engineering Design Process

Have you ever wondered how your phone or email automatically detects and filters junk messages into spam? This feature helps ensure you focus on the messages that truly matter. In this project, you’ll build your own spam detector using natural language processing (NLP) techniques. Read more

Click a Button Without Your Hands: Design a Puff Switch

Science Fair Project Idea

Engineering Design Process

Have you ever wondered how you could push a button without using your hands? How would you type on a computer or play a video game? You could use a puff switch - an electronic switch activated by blowing into a straw. This type of assistive device can help users with limited mobility or physical disabilities do everything from using a computer to steering a wheelchair. In this project, you will design, build, and test a puff switch that is connected to a tiny programmable board that you can use… Read more

Climb Every Mountain with Your Own LEGO® Cable Car

Science Fair Project Idea

Engineering Design Process

If you ever rode in a cable car, ski lift, or gondola, you know they make moving over obstacles like lakes, valleys, rivers, or even up steep mountains seem easy. Though it would be pretty difficult to build a full-size cable car in your home, if you have a Mindstorms® kit, you can build a working-model cable car of your own. The engineering challenge is to build a LEGO® cable car that can travel across a string you have suspended somewhere in your house (between two pieces of… Read more

Have you ever tried to guess the temperature of the water in the pool? On a hot day, the water might feel chilly at first, but once you’re in, you don’t notice the temperature as much. On a cool day, though, the pool water that is the same temperature often feels quite comfortable. Is it all relative? Is our body equipped to tell absolute temperature? The question might make you curious about how our body collects information about our environment, processes it and forms our… Read more

Cold Room? Heat It Up with A Homemade Solar Air Heater

Science Fair Project Idea

Scientific Method

What do humans need to survive? We need food, water, and warm shelter. We all need a warm place to live, particularly when it's chilly outside. How do many of us warm our houses or apartments? We depend on fossil fuels to supply gas and electricity to our heaters. But burning fossil fuels to create energy is harmful to the environment. What if there was a way to warm our homes without burning fossil fuels and it was free? In this science fair project, you will build a solar air heater and see… Read more

Color Profiles

Science Fair Project Idea

Scientific Method

Did you know that the same digital photo you see on a computer monitor may not look as good in print? When it comes to color profiles, there are a lot of options: RGB, CMYK, grayscale and indexed color! How do you choose the right color profile for the job? Read more

Color Theory

Science Fair Project Idea

Scientific Method

Advanced students might want to look for an experiment in the areas of color theory or gamma and light curves. Following web page can help you get started: Color Theory Fundamentals for Digital Photography Read more

Colorizing Images from the James Webb Space Telescope

Science Fair Project Idea

Engineering Design Process

The James Webb Space Telescope (JWST) has shown us some amazing images of space, like its first "deep field" image (Figure 1). The JWST sees the universe in the infrared part of the electromagnet spectrum, which is not visible to the human eye. How, then, does it produce color images like the one in Figure 1? Scientists must colorize the images, or apply "false color." They map different bands of the infrared spectrum to colors of visible light, resulting in an image humans can view. Luckily,… Read more

Column Chromatography: Can you Separate the Dyes in Grape Soda Using Space Sand™?

Science Fair Project Idea

Scientific Method

What color is grape soda? If you pour it into a clear glass you can easily see it is purple, but that is usually not its natural color. Manufacturers add red and blue dye to the soda. The dyes mix together and you get purple soda. What if you wanted to un-mix the dyes, could you? Yes! In a chemistry laboratory, using a technique called column chromatography, you could separate the two dyes again. But what about at home, can you use low-tech supplies to do the same thing? In this science… Read more
