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...

You can eat a solar cell? A unit on solar energy begins with a discussion about organic solar cells, followed by directions on how to build your own. After following the teacher's directions to build an anthocyanin...

High schoolers conduct an experiment using the reaction of hydrogen and oxygen. After pairs balance the chemical equation for making water, they mix different ratios of hydrogen and oxygen in a chemical reaction. Classmates...

Whose home is it anyway? Design teams plan a housing development in which they must also protect a native species. The teams consist of a project manager, civil engineer, environmental engineer, and graphic designer. Teams present their...

I can get more water to stay on a penny than you can! Collaborative pairs determine the volume of liquids that can be contained on the surface of copper pennies and plastic coins. The pairs analyze their results using graphs and go on to...

Learners with special needs discuss the importance of fire safety. They visit smokey.com, discuss where fires commonly occur, and how to prevent them. They then practice responding to a fire-related emergency.

Creating buildings that reach hundreds of feet into the sky is no easy task. The third instructional activity in this series begins with four activities that engage young architects in exploring the major challenges that are faced when...

With rising oil prices and increasing concerns over global warming, the pressure is on for engineers to develop alternative sources of energy. Among the new technologies being developed are hydrogen fuel cells, which young scientists...

Wave goodbye to the same old demonstrations for alternative energy sources, and wave hello to this one investigating ocean waves! Using a water bottle to create an oscillating water column, learners see and possibly hear how the...

Make electromagnetic eddy currents evident with this demonstration. You will need to gather a few materials from the local hardware store and a strong neodymium magnet, but the visual value is well worthwhile.

Discuss different sources of energy and how much greenhouse gas each might emit. The six sources are then ranked according to emissions from greatest to least. Finally, the true cumulative emissions are revealed to show the class how...

Readers use context to determine the meaning of words found in a short article about earthquakes and the movement of the earth's crust.

What happens in the muscles during anaerobic and aerobic exercise, and how does this affect the heart and our overall health? A cross-curricular lesson that introduces learners to the lifelong benefits of exercise, including the...

What is the difference between a form of energy and a source of energy? This first activity in a series of 19 lessons uses demonstrations and discussions to introduce energy to the class. Through using hand-generator flashlights,...

Students identify the different types of batteries available in the market. For this science lesson, students discuss how to select the right batteries for a car.

Instructions for building a simple electromagnetic motor are provided for the teacher. Aside from some sketchy background information and a list of content standards to be met, that is about all you will find in this resource. The motor...

Reinforce the neural connections in the brains of your young biologists with a simple anatomy worksheet. Looking at the provided diagram of a neuron, students are asked to correctly identify and describe the function of...

In this science worksheet, pupils are involved in questions about the events that cause and sustain fires. The chemistry of fire is the primary focus.

Students use a shower curtain to represent a coordinate plane and then physically demonstrate their understanding or ordered pairs as they move from place to place.

Eighth graders examine a free-form sculpture technique and produce a sculpture of wire, pantyhose and plaster.

If your future physicists know how to construct simple circuits, include resistors, and use a multi-meter to measure voltage, then you might employ this lesson on Ohm's law. Each lab group investigates the relationships among...

Young learners participate in activities which help them understand analog clocks, and the vocabulary of telling time. They examine the values of the intervals of minutes and hours by making a human clock.

Are your English language learners using Spanglish when they don't know the appropriate word? Have them study the chart at the top of the page. First they match the Spanglish phrase to its proper English meaning, and then they translate...

Most of these questions are actually not numeric in nature as the title indicates, but they are pertinent to a high school physics curriculum covering magnetic fields. Young scientists must be adept at handling the right hand rule in...
