Everything can be reduced to atoms. The first installment of a six-part Mixtures and Solutions unit focuses on the building blocks of matter. Scholars review basic atomic structure, including protons, neutrons, and electrons, in...

Teams must determine the size of cavern needed to house the citizens of Alabraska to protect them from the asteroid impact. Using scaling properties, teams first determining the number of people that could sleep in a classroom and then...

Time is growing short. Teams work together to identify physical properties of rocks in order to determine the properties that would best suit their cavern shelter design.

Are your household devices eating up a lot of energy? Pupils investigate household energy efficiency through a set of activities. They find ways to improve energy efficiency and reduce consumption. This is the 21st installment of a...

Math rocks! Cavern design teams determine the rankings of rock types based upon desirability points. The points are connected to the properties of the rocks and their usefulness in building a cavern. 

Oh, no! An asteroid is on a collision course with Earth!. Class members must rise to the challenge of designing a shelter that will protect people from the impact and permit them to live in this shelter for one year. In this first lesson...

Stick this resource in the "Use" column. In the second installment of a six-part series, learners use glue sticks to demonstrate forces. Using glue sticks, instructors can demonstrate tension, compression, and torsion.

Did you know that there are over 200 different types of cells in the human body? One type, the stem cell, is the focus of the fifth of six installments in the Cells unit. The lesson asks the class to discuss stem cells and their...

What are the trade-offs when looking to get the most benefit from an energy source? Small groups compare the cost-to-emission levels of several energy sources by looking at the information graphically. The groups utilize this...

Can you design the perfect chair? Scholars apply the engineering design process to design and build a prototype of a new type of chair from wires. They test their designs with a wooden artist model or stuffed animal.

Here's your chance to save the world. The eighth lesson in a 25-part Energy Systems and Solutions unit has young scientists come up with ideas for individual or group projects. They identify ways to solve the energy crisis. Hope they...

Don't drop the ball on the resource ... drop an egg instead! A teacher-led demonstration has the class consider how to drop eggs into glasses when a tray is in the way. Hint: If you've ever seen a magician pull a tablecloth off a table,...

Need some activities to go along with your unit? A collection of hands-on activities from PBS offers opportunities to add to your electricity, sound, and force units. The electricity activities revolve around building a...

Keep everything under control. The lesson, the 16th segment in a 22-part unit, provides a more detailed look at the parts of a plane, specifically the control surfaces. Pupils learn about the construction of the wings and the tails and...

Too much material will weigh you down. The sixth segment in a series of 22 highlights how weight affects a plane. Pupils learn that engineers take the properties of materials, including weight, when designing something. 

Bend it, but don't break it. Groups investigate the strength of different materials. Using a procedure in the seventh segment of a 22-part series on aviation, pupils determine how far a rod will bend. They determine the strength-to-mass...

Which modification is the best? Using the scientific method, pairs determine the effects of each control surface on the distance of a glider's flight. The activity, section 16 in a 22-part unit on aviation, allows pupils to gain a better...

Clay itself sinks, but clay boats float. Why? Young engineers build clay boats to learn about buoyancy. They test the weight the boats can hold using washers and then tweak their designs to make improvements, following the engineering...

Reduce the pressure in the classroom. The second instructional activity in an Airplanes unit of 22 introduces the class to Bernoulli's Principle. Pupils demonstrate the principle by blowing between different objects causing a reduction...

Do not let the pressure get to you. The first lesson in a unit of 22 introduces the concept of air pressure. Using background knowledge, the resource gives teachers the information they need to discuss how people measure air pressure and...

Do not let friction drag you down! The 11th segment in a series of 22 focuses on the fourth force acting upon an airplane—drag. Pupils learn about the effects and causes of drag.

Get the class up and going with a lesson that discusses how airplane wings provide lift. Pupils use their knowledge of Bernoulli's Principle to develop an explanation of how it creates lift on airplane wings.

To go or to not to go — the question for a mission to Mars. This resource provides details for a possible manned mission to Mars. Details include a launch schedule, what life would be like on the surface, and how the astronauts would...

Force the plane through the air. The lesson introduces the force on an airplane that makes it go forward. Pupils learn how Newton's laws of motion apply to flight in the eighth segment of a 22-part unit on flight.
