Ever wonder why most people love patterns? We see patterns in art and music, and also in our daily lives. Patterns can provide a sense of order and can make a hectic-looking world a little more manageable. They are the basis of many assumptions and predictions. We assume we will have lunch at noon, as that is what we always do; we predict thunderclouds will bring rain, as these clouds always bring rain; and you might expect your parents to get mad when you disobey, as that is what has followed… Read more

Investigate the 'Death' of an Orange: How is Rate of Heat Loss Based on the Surrounding Temperature?

Science Fair Project Idea

Scientific Method

Imagine that you are a detective investigating a murder. You have a body that was found in a swimming pool, and someone reported hearing an argument near the pool at 10:00 PM the night before. Your first question might be "Was this person killed around 10:00 PM last night, or at some other time?" One way to answer this question is to measure the internal temperature of the body. The longer ago the killing occurred, the colder the body. But can you assign a specific time of death to a specific… Read more

Is your Physics Textbook Lying? Linear & Nonlinear Springs

Science Fair Project Idea

Scientific Method

Spoiler alert: Your physics textbook might contain an inaccurate equation. Are you shocked? Let us explain — many questions in your physics textbooks are simplifications of how things behave in the real world. For example, in physics textbooks, springs are usually modeled with the equation Force = stiffness x displacement: Equation 1: [Please enable JavaScript to view equation] … Read more

Did you know that you can use your phone as a scientific instrument to explore the world around you? Your phone contains tons of built-in electronic sensors that can measure things like sound, light, motion, and more! In this project you’ll use your phone’s microphone to examine the loudness of different sounds in your environment. How quiet is a library? How loud is that truck roaring by? Try this activity to find out! Read more

Do you enjoy getting together with family and friends to sing familiar holiday songs? It can be fun to do this time of year, gathered around a piano with a warm fireplace nearby, or bundled up together outside. Have you ever wondered what the highest note is that you can sing? How about the lowest? Or what about other people – do you think males and females can reach the same notes? How about children and adults? In this “note”-worth science activity, you’ll get to… Read more

Skiing and Friction: How Does Ski Wax Affect the Sliding Friction of Skis?

Science Fair Project Idea

Scientific Method

You can model this with an ice cube sliding down a plank: how high do you need to lift the end of the plank before the ice cube starts to slide? Try this with one side plain wood and the flip side waxed wood (use paraffin wax, candle wax or ski wax). Make sure both sides are equally smooth to start with. Do at least three trials. More advanced: using what you know about the forces acting on the ice cube, derive equations to calculate the coefficient of friction for each case. Variation: chill… Read more

Have you ever watched a Slinky "walk" down a flight of stairs and wondered how it works? It's a fascinating thing to see and a big part of the Slinky's appeal. These spring toys have been popular for well over half a century; your parents, or even grandparents, may have played with them. Slinkies not only make fun toys, they are also great for doing physics and engineering activities. In this activity you will investigate how the angle of an inclined plane affects how well a… Read more
