Probability and Playing Cards: Hands-on Family Math

Blog Post

A deck of cards provides a concrete look at probability and chance in a hands-on math activity that easily scales up and down in difficulty to match the experience of your students. A Deck of Cards Four suits. Thirteen cards in each suit. Twelve face cards. Four aces. Twenty-six red cards. Twenty-six black cards. Using these simple facts about a deck of cards, many math questions and scenarios rise to the surface! How likely is it that you will draw an ace from a full deck of cards?… Read more

Program a Sound Level Meter to Help Protect Your Hearing

Science Fair Project Idea

Engineering Design Process

Have you ever said, "That hurt my ears!" when someone yelled loudly right next to you? Do you cover your ears when a fire truck drives by with the sirens blaring? It is good to protect your ears—even sounds that do not "hurt" can cause hearing damage if you are exposed to them for too long. In this project, you will program a device that alerts you when sounds have exceeded safe levels long enough to cause hearing damage. 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

Programming NANORGs in a Virtual World

Science Fair Project Idea

Scientific Method

Imagine yourself as a software engineer, a decade and a half from now. You are called upon to help solve the world energy crisis by programming nano-organisms (NANORGs) to extract energy from industrial sludge. Your program must be small enough to fit in the NANORGs' tiny processors, yet at the same time meet several challenges. First and foremost, your NANORGs need to navigate on their own, extract energy from the sludge, and find collection points to deliver the harvested energy. Second,… 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 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

Explore alternative energy and electronics with the Veggie Power kit -- and a pumpkin (or other fruits and vegetables). Hands-on STEM with Science Buddies. Pumpkin Patch Science With Halloween just around the corner, pumpkin-based science can be a fun way to get hands-on during science class or at home. With… Read more

Puppy Proportions: Comparing Growth Spurts and Weight Gain in Your Dog's Early Months

Science Fair Project Idea

Scientific Method

Planning on getting a new puppy soon? Why not use some of your play time with puppy to study growth rates and puppy development? You can easily chart a young puppy's weekly weight and growth over several months to compare how quickly body dimensions and bone lengths change. While this project may take some time, it's well worth the effort. You might be amazed at the dramatic growth of your "canine kid," and what other project combines science with as much fun, or a more adorable subject? Read more
