Students experience and study cause and effect as they assess the consequences man faces when time travel is attempted. They determine, in their imaginations, what time period they would like to visit. Each student then listens to,...

High schoolers listen to a short story, A Sound of Thunder, and retell parts of the story which is about time travel. They respond to the story by writing cause/effect outcomes about the ecosystem using a handout.

Many of us focus on the causes and effects of the Dust Bowl as it relates to people. Why not shift the focus of cause and effects to how the Dust Bowl affected the environment. Here is a different take on the tried-and-true Dust Bowl...

Is qualitative or quantitative research more convincing when it comes to climate change? In the eighth lesson during this 21-part series, scholars begin by performing a quantitative analysis of deforestation and urbanization. Then, they...

This well-organized lab activity introduces earth science pupils to the greenhouse effect. They will set up two experiments to monitor temperatures in an open jar, a closed jar, and a closed jar containing water. Ideally, you would have...

Let's talk about earthquakes .... Using the Internet, pupils research what causes earthquakes, how scientists measure them, their locations, and their effects. The resource is not only informative, but it also builds crucial...

Open this lesson by demonstrating the production of acidic carbon dioxide gas by activated yeast. Emerging ecologists then experiment with seashells to discover the effect of ocean acidification on shelled marine organisms. They measure...

We can learn from the past to protect the future. Pairs look at two historical earthquakes: San Francisco, Calif., and Kobe, Japan. Pupils compare the two earthquakes and their impacts, then determine how engineers may use the...

Make sure your scientists are reporting their work effectively by providing them with a reference for their lab reports. The first few pages of this resource detail each element of a lab report, and the last few pages provide an example...

Human impacts on the environment can sometimes be difficult to measure, especially under water! An activity centered on ocean acidification gives science scholars the opportunity to examine the effects of carbon dioxide on marine life....

Students examine data to investigate the impact of lead shot pellets on waterfowl populations. They graph their findings and discover how lead in ingested by birds and poisons them. As an extension, students research legislation and...

Students reflect upon the causes and effects of light pollution in the night skies. First, they read articles provided and then do worksheets that are provided. They work in groups to discuss their conclusions.

Students are given some components of an experiment, where they are able to identify and fill in missing parts, such as hypothesis, conclusion, results, etc. They form a hypothesis given general scientific facts. Students apply the...

Learners examine pollution and how it affects the environment. They discuss how human activities lead to more pollution. They talk about the importance of recycling. There is a skit, resource links, and activities provided to make this a...

Students examine the causes and effects of alterations in a forest ecosystem and evaluate how human actions may only seem to have minor consequences, but can lead to extinctions of large numbers of populations. Students produce an...

Pre-assessments are great to help teachers determine what information their classes lack, what misconceptions they have, and how in depth to teach specific concepts. The first in a five-part series is a pre-assessment of middle...

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...

The I-STOP law was designed to regulate the distribution and tracking of prescription drugs. After reading an article about its signing and implementation, middle and high schoolers work together to come up with their own ideas for an...

First graders consider the problem of too much garbage in America. In this garbage use activity, 1st graders discuss ways to decrease garbage in the United States and complete a coloring sheet. 

A video and laboratory investigation are highlights to this lesson on acidification of ocean water due to increased atmospheric carbon dioxide. Using bromothymol blue (BTB) as an indicator, pupils analyze the amount of carbon dioxide...

High schoolers will examine how floods work and why they can cause so much damage and destruction. They use a stream table to observe the processes that lead to flooding and the effects of floods on human-made structures. Includes a...

Students explain how melting glaciers affect global warming. In this earth science lesson, students investigate the change in ice density as it melts. They discuss the human and environmental impact of rising sea levels.

Students explore different natural and manmade disasters through a webquest. In this earth science lesson, students explain their causes. They also discuss how disasters affect society.
