Coffee Buzz: How Does Caffeine Affect the Physiology of Animals?

Science Fair Project Idea

Scientific Method

Caffeine is a type of chemical called a stimulant. When you drink a caffeinated beverage, the caffeine enters into your blood stream dilating the capillaries and causing blood to flow more quickly. This gives your body a feeling of speeding up which can cause the jitters and wakefulness. How does caffeine affect the physiology of other animals? You can use over-the-counter caffeine supplements, like Vivarin, to test the effects of caffeine on animals. Try dissolving the caffeine in… Read more

Engineering Design Process

Have you ever wondered how your smart devices can recognize and distinguish your face from that of others? In this project, you will explore how to create and modify a facial recognition model using a type of artificial intelligence known as neural networks. This project is designed for beginners and requires little to no coding experience. Ready to give it a shot? Read more

Create and View Your Own 3D Models in Virtual Reality

Science Fair Project Idea

Engineering Design Process

Virtual reality (VR) headsets are becoming increasingly popular. Video game designers use a variety of programs to create the amazing 3D worlds that you see when you turn on your favorite video game, and many of those worlds are now also designed to be compatible with VR headsets. Can you use a computer-aided design (CAD) program or video game engine to design your own virtual world that can be viewed using a VR headset? Table 1 lists several CAD programs and websites that you can use to make… Read more

Creating a Video Game for Players with Visual Impairments

Science Fair Project Idea

Engineering Design Process

Do you enjoy playing video games? Do you like the challenge of reaching a difficult game level and scoring lots of points? Video games include many graphic elements that are great to watch, but did you know that not only sighted people enjoy video games? Blind and visually impaired players can also play video games by relying on sound cues — the pings, pops, bangs, and bursts of music that make a game fun or exciting. When building a game that will be accessible to differently abled… Read more

Crystal Ball Math: Predicting Population Growth with Models

Science Fair Project Idea

Scientific Method

When is an animal considered endangered? When will it become extinct? What happens when a population has reached the limits of its resources? What happens to a population when a habitat changes? These are some of the questions population biologists try to answer. They use population models, created from math equations, to predict what will happen to a population over time. If you want to see how modeling is done and make some predictions of your own, you certainly won't need a crystal… Read more

Dancing Water Droplets

Blog Post

With this week's fun family science activity, you can create an exciting visual display using water and food coloring! How do water droplets react on a surface material? Do they roll off? Do they disperse? Do they move together? How do they react to each other? Depending on the surface material and the liquid, you may find that droplets move in a variety of different ways. These patterns of movement demonstrate several different science principles. What determines whether droplets spread… Read more

Decisions, Decisions: Judging a Book by Its Cover?

Science Fair Project Idea

Scientific Method

This project challenges you to think like a politician (and a scientist!), and try to ascertain what factors are most important as individuals make their decision on how to vote. For example, is it what is being said, or who is saying it? Read more
