Ice is nice, and its condition on the planet has a significant effect. Junior geoscientists experiment with ice melting in both water and on land to discover how each affect the rising sea level. This detailed lesson outline even...

Introducing enzymes and the controlling factors of a reaction this slideshow displays the typical rate of reaction graph and labels the main sections. The summaries of ways to measure reaction rates are valuable and the examples of...

Based on the rate of melting observed from 2003-2007 in Greenland, it would take less than 10 minutes to fill the Dallas Cowboys' Stadium. The 17th instructional activity in a series of 21 has scholars use the ICESat data to understand...

In this slope of a line worksheet, students read about line graphs and plotting the slope of a line. They read about the rate of change which is represented by the slope. Students practice finding the slope of lines.

A hands-on lesson using the TI-CBR Motion Detector to provide information to graph and analyze. The class uses this information to calculate the slope of motion graphs and differentiate scalar and vector quantities. There is a real-world...

How does a hot air balloon fly? An experimental lesson has scholars build a balloon from a garbage bag and monitor the movement of air. As the temperature of the air in the balloon increases, gravity moves the denser cool air down,...

Investigate the relationship between temperature and pressure. Learners change the pressure of a sample of air and monitor its temperature. They learn that as air decreases its pressure, its thermal energy converts to kinetic energy.

How quickly do enzymatic reactions occur? Assist the class as they examine heat and pH change to determine the rate of chemical reactions using catalase as an enzyme. Watch them "glow" with excitement!

Biology classes will bubble with excitement as they complete this assignment. Beginning with an informative overview of cellular respiration and fermentation processes, the highlight comes as an experiment in determining the rate of...

Students read two different articles which present the scientific issue of asthma, the causes, and the rising rates in our society. Students read for facts and examine whether or not the scientists have a political point of view....

If the Greenland ice sheet melted, sea levels would rise by about 20 ft; if the Antarctic ice sheet melted, sea levels would rise by 200 ft. Scholars explore ice melting through the analysis of different ice samples, clean and dirty ice....

"Waiting to Move," a photo essay by Ciril Jazbec, brings into sharp focus the threats posed by climate change. Class members examine images of Shishmaref Island and the Native Alaskan Inupiate coastal villages that are impacted by rising...

Oh, no! An asteroid is on a collision course with Earth!. Class members must rise to the challenge of designing a shelter that will protect people from the impact and permit them to live in this shelter for one year. In this first lesson...

Due to the isolation of seamounts, their biodiversity offers a great deal of information on the development of biological and physical processes. Pupils use simple cluster analysis to rate the similarity and differences in biological...

The climate at the equator is hotter than the climate at the poles, but why? The instructional activity goes in depth, explaining how the angles of illumination relate to the heating rate at different latitudes and seasons. Scholars use...

Students read an article about cancer in the United States. They research a cancer of their choice along with possible treatments. They identify types of cancer that are on the rise and decline for both men and women. They examine the...

Biochemists experiment with the oxothermic decomposition of hydrogen dioxide by adding manganese dioxide. They observe how pepsin enhances the action of acid on the digestion of egg white proteins. They use yeast to make bread rise. All...

Using a colorful infographic handout and a guide sheet, hold a class discussion about how a bathtub can serve as a model for the greenhouse effect created by Earth's atmosphere. Participants will understand that as energy or matter is...

An informative presentation covers motion, metric system, conversions, graphing of coordinates and lines, speed, velocity, and acceleration problems, as well as mean calculations. This is the first lesson in a 26-part series.

Students explore population growth. They calculate how long it takes a country's population to double in size and to investigate factors affecting growth rate. In addition, they list of factors they think might affect growth rate

Students are introduced to chemical reactions, reaction rates, chemiluminescence, fluorescence and bioluminescence. They use glow sticks are used to demonstrate the effect of temperature on the rates of chemical reactions. Pupils recall...

Students investigate photosynthesis in water plants. For this photosynthesis lesson plan, students use the elodea plant and observe gas bubbles released to determine the rate of photosynthesis. They vary the light intensity and the...

Scholars use their communication skills to express their take on climate change in the ninth installment of the 10-part Discover Your Changing World series. They create ways to deliver their messages on a specific aspect of climate by...

Students explore visosity of matter. They run tests of various liquid substances to observe and compare rates of flow of different substances. In addition, they relate viscosity to distance travelled by sample substances.
