Introduce your class to air masses and how they affect the weather with a lesson that focuses on the differences between high and low air pressure systems. The class explores actual weather data using archived weather data.

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...

How many humans does it take to power a light bulb? The 10th part of a 25-lesson Energy Systems and Solutions unit has learners conduct an experiment to calculate power. They then use the results to determine how many classmates they...

Present the class with a question on whether the water level of a pond will rise they take a large rock out of a boat and drop it into the pond. Groups come down on all sides of the question and try to justify their answers. The activity...

Our young scientists have now specifically identified a problem, and this step helps them think of possible solutions. An outline, including guidelines, for brainstorming helps scholars stay on the right path. The resource includes...

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...

Let's hope that your soap is doing what it's supposed to! The second of six installments in the Cells unit has scholars perform an experiment cultivating bacteria in Petri dishes. They test soaps and detergents to see which is most...

Clay's as good a material as any to build a boat, right? An introductory lesson sets the stage for two activities associated with buoyancy. The first involves building boats out of clay, while the second uses these boats to measure the...

Even magicians can't make energy disappear. In a discussion-based lesson, young scientists learn about energy forms and conversions. They see how energy is neither created nor destroyed; it just changes forms. This is the 11th...

The data says ... the resource is great to use. Using Microsoft Excel, pupils analyze data from the US Department of Energy in the fifth lesson of a 25-part Energy Systems and Solutions unit. Each group looks at a different data set and...

Sometimes it's okay to eat your science experiment. A hands-on activity has pupils create models for algae to learn about its cellular structure. The best part of the experiment? The resulting juice-filled gels are edible—yum!

A long-term project has scholars consider ways in which sensors help monitor physiological stress levels of rescue workers. They design and create a portable device for this purpose. Techies to the rescue!

We've talked a lot about energy, but where does energy come from? Pupils brainstorm different energy sources through a class discussion to kick off the 14th installment of a 25-part Energy Systems and Solutions unit. They then research...

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. 

The liquids did not mix — so what do density columns have to do with it? The seventh part in a series of nine provides the theoretical explanation of why density columns do not mix. The instructional activity covers the topics...

Paper is made from paper, right? Future scientists take bits of paper and produce sheets of recycled paper. The only drawback? It has to dry overnight.

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...

Introduce your class to map projections and coordinates, the basics for the work done in a GIS, with an activity that uses Google Earth to challenge learners to think about the earth's shape. 

Everything in moderation, especially candy. Scholars design and build a dispenser for candy. But, they can't get too carried away—only three or four pieces of candy can come out of the dispenser at one time.

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...

Class members use mathematics in order to better understand magnetic forces and their interaction on charged particles. After a demonstration of the interaction between a magnet and an electron beam using a CRT computer monitor,...

Using the resource is probably the most efficient way to learn about efficiency. The 18th installment of a 25-part Energy Systems and Solutions unit has pupils investigate energy efficiency through discussions and associated activities....

Use food coloring in electrophoresis. The last segment in a four-part series mimics DNA fingerprinting by using chromatography. Teams conduct chromatography on food coloring to find colors that use similar pigmentation in their makeup.

It's time to slow your roll! Can your class create a track that allows a marble to roll as slowly as possible? Teams of science scholars collaborate to design, build, and test their tubes while learning about gravity and friction.
