Remind your middle school scientists how fox ear size varies depending on the climate they live in; large ears allow heat loss while small ears keep heat in. Discuss how a cold-blooded animal might try to regulate body temperature. Then...

Take a "conservative" approach to planning your next unit on mass and matter! What better way to answer "But where did the gas go?" than with a lab designed to promote good report writing, research skills, and detailed observation....

Third graders discovver what causes the dramatic colors of a sunset by seeing the changing color of light as it passes through a clear container of water to which milk is gradually added. They measure the liquids and observe what happens...

Learners study a way to quantify the process of photosynthesis during a given time using the Elodea plant. They design a hypothesis that they test in the hands on activity. They compare the amounts of photosynthesis that occur during low...

Referring to the periodic table of elements, nuclear physics learners determine the resulting elements of alpha and beta decay. Answers are given in atomic notation, showing the atomic symbol, mass, atomic number, and emission particles....

Look beyond the light! An engaging activity introduces young scholars to the application of a spectroscope. The instructional activity is the fifth in a series of six and focuses on the analysis of the elements of the sun.

Young scholars demonstrate understanding of food chain by assuming roles of animals, playing tag, and simulating feeding relationships.

Learners explore the many different food chains. They participate in a game in which the class is divided into the different parts of the food chain.

Stars exist from a few million years to over 10 billion years, depending on their mass. Scholars perform a play acting as stars to learn about their different life cycles. They develop an understanding of many of the fundamental concepts...

How many parts make up the water cycle? How many things on Earth rely on water as a system? Learn more about the water cycle in an informative and colorful poster. Print and hang, or project the graphic in the classroom for optimal use.

It may not stand as a cohesive presentation, but individually you may find a use for these slides. One slide describes how civilization began once man learned to plant and harvest food. Another explores the population growth over time....

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...

Beginning with a general discussion about natural gas, methane, and hydrocarbons, a few videos and diagrams are projected to support the lecture. Individuals participate in a brief activity by drinking juice through a straw, and then...

Ninth graders discuss the principal source of energy entering the marine ecosystem. They name some of the autotrophs at the Maui Ocean Center. Students name some of the heterotrophs at Maui Ocean Center. They are taught that plants are...

Students study day-lighting and other types of light bulbs that are used for energy efficiency.  In this engineering lesson students study the light bulb parts and the light wavelength.

Young atmospheric scientists create models of an atmosphere with and without clouds to determine the effect of cloud cover on Earth's temperatures, as well as figuring out whether dark or light surfaces absorb more energy. You may wish...

Young scholars list sources of phosphorus in soil. They explain how phosphorus is removed from the soil and used by plants. Students list the symptoms of insufficient or excess phosphorus. Young scholars perform experiments to examine...

Students examine the carbon cycle and how carbon atoms travel through it.  In this energy cycles lesson students describe how human activities affect the carbon cycle. 

Students learn about the kinds of fossils and what scientists can learn from them.  In this earth science lesson, students are told how engineers and paleontologists work together.  Then students create a "fossil fondue" and...

Written for an exploration of shoreline ecosystems on Sheffield Island, this gives ecology or marine biology buffs a hands-on experience. Using GPS or visual triangulation techniques, they lay transect lines on a high and a low energy...

Here's a fine instructional activity on renewable and non-renewable sources of energy for your 5th graders. In it, learners list a number of natural resources on the board, then try to sort the resources into appropriate categories. This...

Students examine the radiation budget and the launching of the Budget Satellite. They role-play as designers of the satellite and construct one with a power source, instruments, and sensors. they explain how their satellite functions...

I scream, you scream, we all scream for ice cream! Even high schoolers enjoy making ice cream. This laboratory exercise has them record the temperature changes throughout the process of liquid becoming solid, graph the results, and...

Third graders explore the sources of the various foods they eat. They examine how everyone is intricately connected to the ecosystems in which natural resources are produced. Students observe how the lives of people living in those...
