In this worksheet, students complete 11 multiple choice questions about gorilla's physical characteristics, life span, and weight. Answers are provided.

How does a change in pH affect the ocean ecosystem? Scholars explore the idea by making an acid-base indicator in part seven of the 10-installment Discover Your Changing World series. First, they explore impacts of carbon dioxide in...

Students explore how and why local convective, possibly severe, storms develop. They examine how hailstones form and the conditions under which they form. They test mock hailstones of varying sizes to investigate the impact and damage...

Students test water to determine the dissolved oxygen content while displaying the proper use of testing instruments while visiting water testing sites. They determine if the amount of dissolved oxygen is appropriate for the tested...

Learners observe water samples and measure the samples' water quality. Students develop their own criteria for measuring water quality and test for temperature, acidity, oxygen levels, turbidity, conductance, sediment and hardness.

Eleventh graders are introduced to the effect of gravity on plant growth. They describe the major processes and mechanisms by which plants grow, develop, and supply various products, including energy and nutrition, needed by other...

It may be time to get to know the skeletons in your family. The first instructional activity in a series of 5, introduces the class to the concept of osteoporosis. The class members brainstorm possible causes and whether the family...

Challenge young astronomers to demonstrate their knowledge of the solar system with this fun open-ended science project. Provided with a short list of requirements, students are given the freedom to use their creativity and whatever...

Sixth graders study the formation of convective storms and test mock hailstones. they graph and analyze collected data.

Pupils study about natural resources and the decreasing amount. They observe the need for trained scientists and engineers. Finally, they take a small test to determine the areas of science they find most interesting.

Learners use standard rulers to measure the length of common classroom items - such as pencils, books, desk tops - in inches and centimeters, and measure weight in pounds. They also answer math questions, such as "How long is the front...

Young engineers are instructed to design and build their own solar water heaters. Then, they calculate the efficiency and cost and compare them to commercially available models. This is a full unit for pupils to apply their knowledge.

The size of a nanoparticle is difficult for pupils to grasp. A hands-on experiment is designed to give your classes perspective. Learners analyze different sports drinks for the content of electrolytes as an introduction to nanoscale....

I can move about freely, but you cannot. The class models the movement through cell membranes by way of passive and active transport. Members of the class play the roles of various proteins, atoms, compounds, and cell actions and mimic...

What happens to light as it passes through a hole? This is the main question centered around the designing of a solar eclipse dynamic art piece that uses a solar eclipse and paper to create a pinhole projection of the art.

Build a sculpture that moves on its own; no power source required! The second installment of a five-part series has individuals create a sculpture that moves with the wind. It can't topple over though, so some type of support is necessary.

"If you can't explain it simply, you don't understand it well enough" - Albert Einstein. The sixth installment of a seven-part series teaches young scientists about the importance of being able to communicate scientific research and...

Students design and create their own heart valves out of a variety of materials. Their heart valves are one way valves designed for water flowing through a tube representing blood moving through the heart.

Young scholars discover that recycling is using a product more than once so that natural resources can be saved and so that we won't need so many garbage dumps and landfills. They see that there are different ways to recycle. Students...

Students perform mathematical calculations to design safety device or enclosure to protect an egg as it is rolled down a ramp at increasing slopes.

Students explore the challenges astronauts face while eating in outer space. In small groups, they design and construct an original model device to assist astronauts eat in a microgravity environment.

High schoolers are given a science reading assignment outside the text followed by a discussion on the content. The reading is augmented with a series of thought questions for students to consider prior to class discussion. They direst...
