Bring on the lights! Using an interactive, characters try to figure out how to light a skate park by examining area and ratios to determine the number of solar panels needed to power them. Pupils design a house with a roof to hold solar...

Learners compare graphs of their data that was generated on a NASA website.  In this seasons lesson students complete a lab activity. 

Middle schoolers discover scales for both the solar bodies' relative sizes and their distances from the sun. They find equatorial circumference and volumes of their solar bodies. Students apply estimation strategies and proportioanl...

Another A+ lesson on the impact of climate change comes to you from the National Earth Science Teachers Association. In this installment, learners model the stratification of water in lakes due to temperature differences. The lab also...

I love lessons that incorporate the arts, they're so engaging and address a more diverse set of learners. Your class will investigate the reasons fish from the coal reef have adapted such colorful fins. They design a fish that uses color...

Young scholars employ poetry as a medium to relay information and express views about significant environmental issues that exist today and to assess their effects on The State of the Planet as we enter the next millennium.

A math and science worksheet prompts learners to simulate how scientists determine populations of animals out in the wild. They use goldfish crackers, paper bags, and a styrofoam cup as their tools. An excellent cooperative group activity!

The reason people first began trading was because of their desires for objects other societies possessed. In the activity, classes discuss why exploration has been a common thread in all societies and where these desires have taken...

Sixth graders conduct a controlled investigation to determine the length of the sun's shadow on a fixed object (i.e., flagpole, telephone pole, etc.) over a three-day period (one day in the fall, one in the winter, and one in the...

Students explore the concepts of float and sink by playing a game where they build things on mud, water, rock and jelly. In this Anthony's sink or float game lesson, students discover what materials remain strong in various conditions....

Young biologists discuss the reasons behind the current use of the plant identification system. They get into groups and identify the characteristics of each species of plant which is described. The keys needed for groups to make...

Seventh graders give examples of local sources of pollution and postulate reasons as to why local sources of pollution can harm the ecosystem. They address the following question in short answer form: "Why is litter/chemical pollution...

Use the classic density demonstration of placing a cola, a clear soda, and a diet soda into a tank of water. Then let learners attempt to pour some of the soda into layers in a clear container. The procedure explains a thermocline, and...

Three steps are needed to extract DNA from learners' inner cheek cells. The procedure and reasons for each step are explained. As enzymes work on the cells, a series of questions are answered regarding the structure of the DNA molecule....

Convection is offered as the reason behind our weather phenomena. This presentation assumes that viewers are familiar with the methods of heat transfer, and is therefore more geared toward middle-school meteorologists. The focus is on...

In a neat and straightforward manner, this PowerPoint delivers basic introductory information on the properties of matter, physical and chemical changes, and pure substances vs. mixtures. It also defines the states of matter. For some...

A wonderful lesson incorporating math and physics skills along with specific details about the planetary bodies. The cross-curricular approach makes for a valid activity to challenge multiple ages and abilities. Your class could work in...

Students develop a strategy list for problem solving by working with different types of problems. They recognize problems that may be solved using deductive reasoning and solve deductive reasoning problems.

Students investigate the reasons why wetlands are threatened especially by people. They study the wise use of water to preserve wetlands.

Review the 5 branches of chemistry and related terms with this worksheet. The focus of these activities is on terms and definitions. Learners answer questions about the study of chemistry, reasons to study chemistry, and pure and applied...

Students explore how climatic factors influence the growth of plants. They create an experiment to find how variations in water, light, and temperature affect plant growth and describe how precipitation and geography can affect the...

What can one learn about a planet based on a small surface sample? Learners will explore artifacts from a mystery planet and see what they can determine about the planet based on the evidence in front of them. 

Students study the concept of animal migration with the change of seasons. They discover that migration can be hazardous, and the distance migrated can be short or long.

If you chew or make a "raspberry" while viewing an LED light source, the light will appear to wiggle or flicker. It is not because of the light itself, but because of the vibration of your skull! Have your physics class give this a try...
