Power Play: How Does Animation Timing Affect Your Perception of Game Action?

Science Fair Project Idea

Scientific Method

"Pow!" Wow, what an awesome punch that character has! Ever wondered what goes into making a punch look good in a video game? Or any other character motion sequence, for that matter? Try this science fair project for a firsthand look at how art and timing can create memorable game action. Read more

Primary Productivity and Plankton

Science Fair Project Idea

Scientific Method

Have you seen plankton? I am not talking about the evil villain trying to steal the Krabby Patty recipe from Mr. Krab. I am talking about plankton that live in the ocean. In this experiment you can learn how to collect your own plankton samples and see the wonderful diversity in shape and form of planktonic organisms. Read more

Are you curious about how public health officials think about and model how diseases like flu and COVID-19 move from one person to another? In this activity, you will use the kid-friendly programming language Scratch to write a simulation that uses bouncing dots to represent healthy and sick people. The simulation will show how we can take measures to slow the spread of a transmissible disease. Read more

Projectile Physics and Catapult Science

Blog Post

Explore the physics behind a catapult with a simple DIY catapult at home. Catapults have been used throughout history as a way to launch something from point A to point B, sometimes over castle walls and sometimes into things. Experimenting with a catapult and launching objects at a target can be fun for families or classes, and a catapult activity invites discussion of both the physics and math at work in the way a catapult operates and in how… Read more

Protein Fingerprinting

Science Fair Project Idea

Scientific Method

First came the Human Genome Project and now (drum roll please) the Human Proteome Project. Confused? Not surprising as the Human Proteome Project has not received the kind of press that the Human Genome Project did. Nonetheless it is a major, and potentially important, scientific undertaking. Just as the genome is the complete set of an organism's DNA, the proteome is all the proteins expressed in an organism. Why study the proteome? It is because proteins are the work horses of biological… Read more

Protein Structure and Function

Science Fair Project Idea

Scientific Method

How a biological system functions is a consequence of the 3-D structures of biological macromolecules like proteins and protein complexes. Proteins can be categorized into different protein families based upon sequence, structure, and function. Typically, proteins in the same family have similar biochemical functions. You can investigate the structure of a protein by using protein databases (Entrez Protein, SwissProt, PDB) and 3-D computational models. You can compare the structures of… Read more

Did you know we use our side vision for many daily activities, like riding a bike, reading or playing basketball? Few people realize they are even using it. Our survival once depended on the quick response of our peripheral vision. A detailed picture, created by our central vision, is only useful in situations where time allows us to focus on the details. But our side vision can help us avoid dangers quickly. In this activity, you will find out how specialized our peripheral, or side vision, is. Read more

Quick Draw McPaws: Teach A Computer Kitty How to Draw Shapes

Science Fair Project Idea

Scientific Method

Have you ever played a computer game in which a cartoon character, like a dog or a cat, moves or turns when you click on it? Have you ever wondered how characters know how far to move or how far to turn? In this computer science project, you will learn how with a simple (and free) program called Scratch, which will let you write your own computer program that tells a cartoon kitty how to draw shapes.
