Is electricity created in the outlet? Using posters of several energy systems, collaborative groups identify and describe the parts of their systems. The groups also look at the environmental impacts of the systems and present...

How does the dirt get out of your drinking water? A hands-on activity introduces the use of flocculants to help clear solid particles out of water. The plan walks learners through the process of setting up an experiment that...

All of the people in your class would agree that life would be different without the invention of the telephone! Study Alexander Graham Bell's most famous and influential invention through the primary source document of his...

Back to the basics (of surface tension). The first installment of a nine-part series teaches young scholars about the basics of surface tension and how it relates to water droplets. They also learn how this concept allows for the...

Are you eukaryotic? (Answer: Yes.) The first of six installments in the Cells units teaches pupils about the similarities and differences of prokaryotes and eukaryotes. It also covers the functions of various cell components in both...

What a bright idea! Young scientists conduct an experiment on flowers to finish the last of a six-lesson unit on Cells. Putting the stems into dye-injected water and leaving it overnight results in flowers that glow. This is to simulate...

Introduce your class to the steps that occur in the manufacturing of parts, the assembly, and the testing of a Mars rover. Pupils learn about fabrication techniques and tolerances in the manufacturing process. 

You've got to pump it up! Using the equations for projectile motion and Bernoulli's Principle, class members calculate the water pressure in a water gun. The pupils collect data on the number of pumps and distance traveled in order...

My, what big energy potential you have! Scholars learn about the energy potential of using algae as a biofuel. A PowerPoint presentation first describes the structure of algae and then how researchers use algae as biofuel to produce energy.

Can corn power the world? Young scientists learn about how corn and other plants can provide renewable biofuels in the second of nine lessons. They set up an experiment to investigate how different variables affect plant growth. All of...

Make Newton proud. Scholars apply their understanding of forces and energy to an engineering design challenge. They learn about simple machines, create a presentation on Newton's laws, and develop a balloon-powered car.

Water is a powerful force; harness it through watermills. The task at hand is to create a simple watermill that functions in flowing water for at least three minutes. Scholars work together in teams to design and construct such a...

What is this thing called the Internet? A KWL activity elicits what the class knows about how the Internet works. Then pupils read a copy of a memo about the need to keep the Internet open and accessible by everyone. 

Sometimes, taking things apart is more fun than putting things together. Groups of learners participate in a reverse engineering activity. They dissect a device of their choosing to see how it works—great hands-on learning from the...

Textbooks are heavier than a sheet of paper, so how can paper hold up a textbook? Young engineers create a structure out of paper that can support a textbook. To add another wrinkle, they must stay within budget and time constraints.

Let the good times roll as young thrill seekers build a roller coaster on school grounds. Future engineers design and build a roller coaster from flexible tubing. The roller coaster is for a marble, so there will be plenty of room to let...

Think you can solve the energy problem? You'll first need to know about current energy use. Analyzing a set of circle graphs lets scholars see where energy consumption is the greatest, both by sector and by household use. They develop a...

You won't regret being stuck with this activity. By mixing a variety of household items, pupils create their own glue. They test the tensile strength of their glue and compare it to that of other adhesives.

You're on solid ground if you decide to use the resource. A simple activity has young engineers investigate the problem of liquefaction. A battery placed on dry sand will stay standing—but not if scholars add water to the cup.

Future engineers design and build structures out of toothpicks and marshmallows. They then make sure the structures can withstand an earthquake simulator!

Train your pupils to be master engineers. Young learners design a train that travels along a fishing line. The train needs to safely carry pennies as passengers without falling out.

Eureka! Using the clay boats made in the previous lesson, learners investigate the idea of buoyancy and water displacement to finish the last installment of five in a Floaters and Sinkers unit. Their observations during the activity...

Dust is everywhere around us; it's unavoidable. But what exactly is dust and are certain locations dustier than others? These are the questions students try to answer in an interesting scientific investigation. Working independently or...

How do engineers determine the most efficient highway designs? Introduce young scientists to the world of topology, the branch of mathematics that examines how things are connected. Teams use model highways to create the most...
