Students determine the meanings of concentration, surface area, and catalysis through an experiment. In this lesson about chemical reactions, students participate in an experiment. Students complete three different parts of the...

Students build simple stream tables and vary the angle of the stream tables in order to simulate different flow rates and compare the results. They observe various features formed in a stream table by flowing water and compare these to...

High schoolers calculate how much mass is lost and gained by Antarctica yearly. In this earth science lesson, students graph and analyze data from the given handout. They explain how this affects the world climate.

Science students apply dimensional analysis to relate quantities in six different problems. They consider the cost of steak, a young man's growth rate, a medicine prescription, fuel efficiency, and more. This worksheet is a great way to...

In this geography worksheet, students read an excerpt about how scientist are examining changes in the Arctic and Antarctic ice caps. They use the information in the excerpt and any other references listed to answer the three questions...

Students plot the current distribution of glaciers around the Earth and see if there any major trends where glaciers appear to be either growing or shrinking at abnormally high rates.

Getting kids thinking about climate change now, will hopefully push them into action when they become adults. Young environmentalists discuss the evidence and causes of climate change seen in the state of California. They brainstorm ways...

Seventh graders research about the effect of climate on different ecosystems. In this life science lesson, 7th graders present their research by creating a poster, infomercial, skit or song. They discuss how organisms adapt to climate...

In this chemical reactions worksheet, students read about the differences between physical and chemical changes in substances. Then students identify situations as either an example of physical or chemical change. Students learn how to...

In this chemical and physical change worksheet, learners read about the differences between substances going through physical changes vs. chemical changes. They are given examples of each and evidence to look for in chemical changes....

Students predict what will happen to ice when salt is put on it. They make observations and discuss what actually happened to the ice. They relate their experiment to the salt trucks they see on the street.

In this environmental science lesson, learners study data and animation on global temperature increase to complete 8 short answer questions that follow.

Students explore the natural distallation process that occurs in the water cycle. They use plastic cups and cotton swabs to observe the condensation process that is evident in the water cycle.

In this Global Warming activity, students read the article, answer true and false questions, complete synonym matching, complete phrase matching, complete a gap fill, answer short answer questions, answer discussion questions, write, and...
