Don’t Forget! A Memorization Exploration

STEM Activity

What did you have for breakfast last Monday? What color is the floor in your favorite classroom? If you don’t remember the answer to these questions, that’s ok! Your brain is doing exactly what it is supposed to do. Our brains are nearly perfect storage devices, and part of their perfection is that they know which information to store, and which to throw away. Imagine your house if you never threw anything away – how quickly would it become full of garbage and waste? Your… Read more

If someone tells you to remember a phone number or address, it can feel like an easy task at first. You repeat the numbers to yourself, either aloud or in your mind. But after just a few seconds, you may find yourself starting to doubt your own memory. Was it 5-7 or 7-5? Our minds are always seeking new and useful information, and as a result, it will try to ‘throw away’ information that seems old or irrelevant, such as a random string of numbers or an address. However, there are… Read more

Don't Get Burned! Measure the UV Index at Different Times of the Day

Science Fair Project Idea

Scientific Method

It's true that the light from the Sun provides the heat and light we need to survive here on Earth, but it also poses a threat. Ultraviolet (UV) rays in sunlight cause damage that can lead to early skin aging and even skin cancer. In this science fair project, find out when you need the most protection from UV rays by using a personal UV monitor to measure how the level of ultraviolet light changes during different parts of the day.

Don't Stand So Close To Me! An Investigation into Personal Space

Science Fair Project Idea

Scientific Method

How do you feel when a friend comes too close to you? How far away or close do you think is necessary to have a conversation with someone? The answers to these questions are dependent upon the size of your personal space. Some people like to be within a foot of each other when having a conversation and others feel that being 3 feet apart is still just a little too close for comfort. Personal space is defined as the protective area surrounding a person's body (not necessarily spherical in… Read more

Draw a Spirograph with a Raspberry Pi

Science Fair Project Idea

Scientific Method

Have you ever used a toy like a Spirograph® to draw precise, repeatable patterns on a piece of paper? What if you could use a computer to automatically draw the patterns for you? This project will show you how to do just that using a Raspberry Pi. Check out the video to see what this simple, but fun, project looks like. IMPORTANT: The instructions for this project were originally written using Scratch 2 on a Raspberry Pi 3B+. If you are using a newer Raspberry Pi running Scratch 3, you… Read more

Dry Spells, Wet Spells: How Common Are They?

Science Fair Project Idea

Scientific Method

Can you remember what the weather was like last week? Last year? Here's a project that looks at what the weather was like for over a hundred years. You'll use historical climate data to look at moisture conditions in regions across the continental U.S. You'll use a spreadsheet program to calculate the frequency of different moisture conditions for each region and make graphs for comparison. Which part of the country has the most frequent droughts? The most frequent periods of prolonged… Read more

Earth Surface Dynamics

Science Fair Project Idea

Scientific Method

Think about mountain ranges, canyons, sand dunes, or any other interesting geological feature you may live near enough to visit. The surface of the Earth is always changing due to a balance of forces both above and below the surface. Below-surface forces cause the Earth's crust to be faulted, folded, tilted, and lifted. Above-surface forces are primarily due to the natural processes of weathering and erosion. Can you show the effects of these forces using scale models, demonstrations,… Read more
