A full-fledged practice final prepares pupils for their general chemistry final exam. If they complete these 57 multiple-choice questions correctly, they will be well-prepared. Note: even though the questions are multiple-choice, there...

Sixth graders explore ways to analyze the properties of water and examine the chemistry of water.  For this water lesson students work in groups and complete several activities. 

Students research bears and their characteristics with a specific study on North American bears and polar bears. In this bear study lesson, students read books about polar bears and wild bears. Students complete activities to further...

Pupils observe and describe, both orally and in writing. the different forms of water on the surface of the Earth and measure the approximate size of an iceberg. They also estimate and measure the amount of ice that floats above the...

Students explain the importance of water in our daily lives. In this aquatic science lesson, students identify different ways to purify water and make it potable. They design and construct a water filter based on researched information.

Young scholars explore the unique behaviors of water. They investigate surface tension using water drops on a penny and pennies dropped in a cup.

Students predict the shape of molecules using VSEPR theory. In this chemistry instructional activity, students differentiate a polar and nonpolar molecule. They discuss why water's polarity is very important.

Radioactive decay, pH, properties of elements, organic compounds, and stoichiometry are all touched upon through this practice chemistry exam. It always helps learners to take a practice test in preparation for the actual exam. This...

The instructions for demonstrating ocean turnover are provided in this resource. You could set this up for your earth science class as part of a lecture on convection currents or as an explanation of how ocean currents form. An animation...

Although biochemistry of the human body is a vital topic, it doesn't have a chapter dedicated to it in many biology textbooks. If that's the case with your text, you can use this resource as a guide for designing your own lecture and as...

There is not much information in this presentation. It serves more as a guide to direct the flow of your introductory chemistry lecture. Each slide displays a large title and a smaller phrase meant to explain it. For example, one title...

Ninth graders examine the electrolysis of water by completing an experiment.  In this water lesson students will explain how hydrogen can be extracted from water and how energy flows through an electrolysis system. 

Knowing about the hydrologic cycle is the first step to understanding the carbon cycle. Upper graders discuss the earth's water content, polar ice caps, and the concept of the ecological cycle as it applies to carbon, nitrogen, and other...

In this solubility worksheet, learners test a variety of polar and non polar substances to determine which ones will dissolve in vegetable oil and which ones will dissolve in water. Students collect data and answer 2 questions about...

Young scientists explore some of the scientific equipment that is used by explorers during expeditions to the North or South Pole. Then, they have a relay race! All of the equipment is lined up at a spot 25 yards away from the lines. The...

Physics lab groups finagle with laser lights to determine the critical angle of refraction for both water and Lucite. Because there are no detailed steps or an answer key for this enlightening exercise, an inexperienced physics...

Use a container full of water as a prism and show that as light is bent, the individual colors from different wavelengths become visible. This explains why the sky appears to be blue midday, and why as the sun nears the horizon, it looks...

Your older elementary students investigate electromagnetic energy and the electromagnetic spectrum. They will observe 7 items represented in the electromagnetic spectrum and make a poster of all the things the items have in common. After...

Students explore how an oil spill is contained and cleaned up. They investigate an oil absorbing polymer that is hydrophobic, absorbs up to 19 times its own weight in nonpolar liquids, floats on water, and can be reused or disposed of by...

What an exciting lab experiment to conduct with your high school chemistry class! Crystals are formed naturally in the environment. However, allow your blossoming chemists to create their own unique crystals using alum and...

Beyond the phases of the moon, this comprehensive lesson plan covers geologic history and geology. Amateur astronauts examine photos of the lunar landscape, experiment with the creation of craters, and delve into information about the...

Students study the sources for the water they use. They determine their town's major water supply and how many gallons per day does the population use.

For this molecular model worksheet, students use a molecular model kit to construct 13 different molecule models. After constructing the molecules, the students complete 32 short answer questions.

In this animals' adaptation to their environment worksheet, students read for comprehension and ability to apply knowledge. In this T-Chart and creative activities worksheet, students answer three questions.
