Plastic Deformation: Glass Transition of Some Plastics

Science Fair Project Idea

Scientific Method

Some plastics undergo an unusual transition, from a hard, glassy state to a soft, rubbery state, with increased temperature. For this project, you should do background research on the effects of temperature on different types of plastics. Make sure that you understand the difference between thermosetting and thermoplastic polymers. You should also look for information on the glass transition temperature (Tg) for different plastics. Pure polyvinyl acetate has a Tg of 28 C (about… Read more

Playing the Angles: The Physics of Balls Bouncing Off of Surfaces

Science Fair Project Idea

Scientific Method

Think of hitting a baseball, heading a soccer ball into the net, or hitting a tennis ball with a racquet. Where the ball goes depends on...what? You can set up a simple model to start your investigation. You'll need a marble, a flat piece of wood, a flat piece of cardboard, a pencil, a ruler, a protractor, and a level surface. Lay down the cardboard down on a level surface and set up the flat piece of wood at one edge. The wood will act like a wall, and you're going to roll the marble at… Read more

Porosity

Science Fair Project Idea

Scientific Method

Soils are made of particles of different types and sizes. The space between particles is called pore space. Pore space determines the amount of water that a given volume of soil can hold. Porosity is the percentage of the total volume of soil that consists of pore space. Compare the porosity of different types of soil. Which types of soil hold the most water? Can you see this under a microscope? Read more

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

Practice

Science Fair Project Idea

Scientific Method

We've all heard that "practice makes perfect," but what is the best way to practice? For example, does "mental practice" do any good? You'll need at least 9 volunteers for this project. Pick a well-defined sports activity, with a measurable outcome, such as shooting basketball free-throws (measure number of shots taken and number of shots made), or balancing on one foot on a slightly raised beam (measure how long you can do it; if it's too easy, try closing your eyes). Test all volunteers… Read more

Pretty Packaging: Can Attractive Packaging Lead to Healthier Eating?

Science Fair Project Idea

Scientific Method

Have you ever bought or tried something new, just because of the way it looked, or the nice box that it came in? On your birthday, which present do you pick to open first? The one that looks big and colorful and exciting or the one that is wrapped in old tissue paper? The way that something is packaged and wrapped often advertises what is inside. But can attractive, exciting packaging convince you to try something that might not be very exciting, but is, perhaps, something that is good for you?… Read more

Processed Cheese, Please! Get Your Grilled Cheese Oooey Gooey Instead of Oily and Gloppy

Science Fair Project Idea

Scientific Method

A delicious and quick lunch is a cup of tomato soup and a grilled cheese sandwich. Biting into the toasty, butter-soaked bread and gooey cheese is very comforting. But what makes the cheese melt so nicely? Do all cheeses melt this way? In this cooking and food science fair project, you will experiment with making and determining the best recipe for processed cheese. Read more

Program to Check (or Solve) Sudoku Puzzles

Science Fair Project Idea

Engineering Design Process

Sudoku is an extremely popular puzzle game. You start with a 9x9 grid of squares, which contains three smaller 3x3 subgrids. Some of the squares are filled in with numbers 1 through 9. Your goal is to fill in the remaining blank squares such that each column, each row, and each 3x3 subgrid contains the numbers 1-9. No number can appear more than once in any column, row, or subgrid. For a given starting puzzle, can you write a program to check if a Sudoku solution is valid using a programming… Read more

Purposeful Packaging

Lesson Plan Grade: 6th-8th

Students will play the role of packaging engineers, exploring how to protect shipped items in innovative ways. Students will use data analysis of consumer surveys to inform the iteration of their materials and designs. Learning Objectives Students will: Design a more sustainable way of packing items for shipment. Collect consumer feedback using surveys. Calculate averages, analyze survey data and evaluate the effectiveness of their design. NGSS Alignment The 3 dimensions… Read more
