Pop Goes the Metal: How Temperature Affects Snap Time of a Jumping Disc

Science Fair Project Idea

Scientific Method

Jumping discs can be a fun toy to play with, and with their sudden POP!, they can even be a good way to startle people who have never heard them before. Jumping discs use a neat trick to jump. They are made of two different types of metal, and these metals expand when they heat up (or shrink when they cool down), but not by exactly the same amount. In this science project you will explore how temperature affects the reactions of your jumping discs— and how to get the timing right if you… Read more

4 reviews

Don't just teach your students about Newton's laws of motion using diagrams in a textbook—try something hands-on! In this project, students will build their own cars using craft materials and explore the relationship between force, mass, and acceleration. Students can graph data and make observations in real-time using a mobile phone and a sensor app or use a low-tech approach with a meter stick and stopwatch. Read more

NGSS Performance Expectations:

MS-PS2-2. Plan an investigation to provide evidence that the change in an object’s motion depends on the sum of the forces on the object and the mass of the object.

In this fun engineering lesson plan, your students will build a rocket-catching device to help a falling rocket land vertically without crashing, using simple and readily-available materials. Elementary and high school versions of this lesson plan are also available. This lesson was part of the 2025 Science Buddies Engineering Challenge. Read more

NGSS Performance Expectations:

MS-ETS1-2. Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.

Have you ever played with your food, creating funny faces or colorful edible artworks? In this activity, you can do just that, but with results you might not expect! You will learn a fascinating way to cook and shape boiled eggs, and explore some interesting chemistry about cooking an egg along the way. While exploring the flexibility of hard-boiled eggs, you will create a delicious, odd-shaped reward! Read more

Simulate Microchip Clean Room Contamination with Crayon Leaf Rubbings

Science Fair Project Idea

Scientific Method

Have you ever made a leaf rubbing or imprint using paper and crayons? What do you think would happen if you got dirt or sand on the leaf? Would it mess up the result? In this project you will find out and learn about how this is related to the process of making the microchips that run our phones, computers, and other electronic devices. Check out this page for more science projects related to this process. 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

Solar Sails: The Future of Space Travel

Lesson Plan Grade: 6th-8th

Working as if they were engineers, students design and construct model solar sails made of aluminum foil to move cardboard tube satellites through "space" on a string. Working in teams, they follow the engineering design thinking steps—ask, research, imagine, plan, create, test, improve—to design and test small-scale solar sails for satellites and space probes. During the process, learn about Newton's laws of motion and the transfer of energy from wave energy to… Read more

NGSS Performance Expectations:

MS-ETS1-4. Develop a model to generate data for iterative testing and modification of a proposed object, tool, or process such that an optimal design can be achieved.
MS-PS2-2. Plan an investigation to provide evidence that the change in an object's motion depends on the sum of the forces on the object and the mass of the object.
MS-PS2-1.. Apply Newton's Third Law to design a solution to a problem involving the motion of two colliding objects.

This activity demonstrates how potential energy (PE) can be converted to kinetic energy (KE) and back again. Given a pendulum height, students calculate and predict how fast the pendulum will swing by understanding conservation of energy and using the equations for PE and KE. The equations are justified as students experimentally measure the speed of the pendulum and compare theory with reality.Engineering Connection Mechanical engineers design a wide range of consumer and… Read more

NGSS Performance Expectations:

MS-PS3-5. Construct, use, and present arguments to support the claim that when the kinetic energy of an object changes, energy is transferred to or from the object.
MS-PS3-2. Develop a model to describe that when the arrangement of objects interacting at a distance changes, different amounts of potential energy are stored in the system.

The Joly Photometer: Measuring Light Intensity Using the Inverse Square Law

Science Fair Project Idea

Scientific Method

You have probably seen light bulbs with different wattages, for example 50 W or 100 W. Higher-wattage lights are brighter but they also consume more electrical power. Are some bulbs more efficient than others, meaning they produce more light per unit of electrical power? You can find out for yourself by making a simple photometer to compare the light output from different bulbs. This project shows you how. Read more
