Do you love playing on a seesaw? Why is it that depending on where you sit on the beam, and the weight of the person on the other side, you either fly up into the air or fall down to the ground? And why is it so difficult to perfectly balance the seesaw? It can all be explained with physics! In this activity, you will investigate the balancing forces of a seesaw—with a seesaw made of candles! Read more

How does light interact with matter? In this fun hands-on lesson, your students explore how different materials transmit, absorb and/or reflect light. They create their own experiments to demonstrate these phenomena and use a phones' built-in light sensor and a sensor app to add quantitative data to their arguments. Read more

NGSS Performance Expectations:

MS-PS4-2. Develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials.

"Diver and Lemon shark" © 2004 Hpm~commonswiki What helps SCUBA divers, sharks, fish, and other marine organisms stay in the water column? In this hands-on investigation, students will explore the concepts of buoyancy and mass to create a device to help an action figure stay neutrally buoyant, just like a scuba diver. 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.

Do you feel like it is always too loud in your classroom? In this lesson you can find out exactly how loud it is. Using a mobile phone and a sensor app, your students will measure and graph the sound levels in your classroom for different working scenarios. How loud are your students when doing independent work, having a group discussion, or listening to their teacher? Based on your students' data, you will determine as a class which sound levels are ideal for each scenario and create a… Read more

NGSS Performance Expectations:

MS-PS4-1. Use mathematical representations to describe a simple model for waves that includes how the amplitude of a wave is related to the energy in a wave.

Come One, Come All! Explore the Effect of Light on the Speed of the Amazing Rotating Radiometer!

Science Fair Project Idea

Scientific Method

Radiometers are fun-to-watch novelty items, but they also have a distinguished scientific history, having been studied by James Clerk Maxwell and Albert Einstein. A radiometer has a set of four vanes (like small sails) connected to a spindle that is free to rotate. When the radiometer is placed in bright light, the vanes and spindle start to spin. It looks like a magic trick, but there is a scientific explanation for this weird behavior. In this science fair project, you will experiment with… Read more

Cricket Wicket Knockdown Challenge for Grades 6-8

Lesson Plan Grade: 6th-8th

Teach your students about the engineering design process with this fun lesson plan. They will design and build a ball-launching machine to knock down a target. Optionally, they can enter their designs in the 2020 Engineering Challenge for a chance to win a cash prize for your school! Teachers, note that elementary school and high school versions of this lesson plan are also available. 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.
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-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.

Do you ever wonder why we perform tasks in a particular way? Very often, we learn by copying someone and never stop to question if there is a more efficient or easier way to do something. This activity is about the tricky task of pouring from a full container. Could there be an easier way to do it? Read more

Did you know that airplanes and sound have something in common? Can you guess what it might be? Air pressure! It is fascinating how air—something that is so fluid and invisible—can power an amazing number of fascinating phenomena. In this activity you will use your own breath to blow a small paper ball into an empty bottle. It sounds simple, but is it? Try it out and see for yourself! Read more
