Image Compression vs. Image Quality: Finding the Best Tradeoff

Science Fair Project Idea

Scientific Method

In this project you'll learn about how digital image files are encoded, and how digital images can be compressed so that the files take up less storage space and can be transmitted more quickly. You will also measure the quality of compressed and uncompressed images, which will give you important insights into the tradeoffs between file size and image quality. Read more

Killing 'Vampires': Saving Money and Power by Turning Off Computer Peripherals

Science Fair Project Idea

Scientific Method

What do you think about killing vampires? No, no, not the kind that drink people's blood, but the kind that suck your power and money away. Equipment like televisions, computers, printers, and fax machines all use electricity to operate, of course, but do you realize that this equipment might still be sucking electricity from the wall, even when you think it's turned off? These electricity-suckers are called vampire loads. In this science project, you will investigate how much power these… Read more

Printing Power! Save the Environment, One Printer Page at a Time

Science Fair Project Idea

Scientific Method

Do your parents ever get upset with you for "wasting" paper and ink from your printer? Maybe you wanted to print a comic you found online, or a whole bunch of pictures of you and your friends being goofy, or all the instructions on how to put together that really awesome LEGO® castle. But 20 pages of text and pictures later, your mom or dad is yelling at you. Why do they even care how much you print? And why do people say it is a "waste" of paper? Try this printer-saving science project to… Read more

How do driverless cars know how to recognize different road signs? They use something called machine learning. In this activity you will teach a computer to recognize different road signs using photos that you take yourself and a tool called Teachable Machine by Google®. The better the training data, the more accurately the program will be able to recognize different types of signs. Read more

Send That Signal!

Lesson Plan Grade: 4th

Here is a challenge for your students: you need to send a number to someone on the other side of the classroom. The twist? You are not allowed to talk, write the number down, or use gestures or sign language! How would you do it? In this project, your students will explore different means of transmitting information by sending a message to a phone that can graph light, sound, and vibrations using a specific sensor app. They will learn about different sensors and interpreting graphs, and use the… Read more
