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

Have you ever wondered what keeps you in your seat when you are riding a giant loop-de-loop roller coaster? Surprisingly, it is not the seat belt! You are kept in your seat because of something called centripetal force. Centripetal force actually does much more than make a ride on a roller coaster's loop possible — it keeps a satellite in orbit and you in your bicycle when taking a tight curve! In this science activity, you will use marbles and Jell-O® to investigate centripetal… Read more

You might have heard the saying “not everything is as it seems.” Something might look great from far away, but when you take a closer look, it might not turn out to be as beautiful as you thought! In this activity, you will create the opposite experience—you will turn a spoon blackened with soot into shiny silver. Even though it is only an illusion, you will not know it when you see it. Try it out for yourself! Read more

You are probably used to seeing things float, be it a boat on the water, or a rubber duck in your bathtub. But did you ever wonder how the same water that you drink, splash, and dive into – how can that support the weight of giant boats? In this activity we’ll learn about surface tension and how it helps us keep afloat! Read more

Volleyball Machine Challenge for Grades 3-5

Lesson Plan Grade: 3rd-5th

Teach your students about the engineering design process with this fun lesson plan. They will design and build two "volleyball machines" that launch a ping pong ball back and forth over a net. While the 2019 Engineering Challenge is over, your students can still try this project and compare their scores to top scores from around the world! Teachers, note that middle school and high school versions of this lesson plan are also available. Looking for this year's challenge? Check out our… Read more

NGSS Performance Expectations:

3-5-ETS1-3. Plan and carry out fair tests in which variables are controlled and failure points are considered to identify aspects of a model or prototype that can be improved.

Lightning is a powerful display of static electricity in nature. But what is static electricity? In this lesson, students will learn about static electricity and electric fields by building a device that can detect electrical charges, called an electroscope. They will use their electroscope to investigate how well different materials can build up electric charges by rubbing them against wool. During their experiments, students will be able to demonstrate how electric fields exert forces on… Read more

NGSS Performance Expectations:

MS-PS2-5. Conduct an investigation and evaluated the experimental design to provide evidence that fields exist between objects exerting forces on each other even though the objects are not in contact.

Have you ever wondered how fish hear the sounds we make when we splash into the water or pass by in a motorboat? Now that the summer vacation is here, you might be spending more time in the water: an ideal occasion to investigate how we hear in the water! Maybe you will feel inspired to research how that transfers to aquatic animals, too! Read more
