Central to good science are accurate observations, testable hypotheses, well-designed experiments or other tests, and reasonable data analyses. The purpose of this activity is to introduce the basics of designing and analyzing experiments. This is accomplished by using a computer simulation that involves the real-world industry of farming fish. The two laboratory exercises include further steps in ... Full description.

High levels of ultraviolet light can be harmful to many biological systems, as this higher energy radiation has a mutagenic effect on plant and animal cells. This activity studies the relationship between the amount of ultraviolet (UV) radiation that gets to Earth's surface and the amount of stratospheric ozone overhead. Users plot remote sensing data from the NASA Total Ozone Mapping Spectrometer ... Full description.

Discussion of holes in the stratospheric ozone layer usually revolves around investigations of the thickness of the layer near the South Pole. This online activity allows users to study the thickness of the ozone layer over any location on Earth to see how it has changed over time. This is done by plotting historical data from the Total Ozone Mapping Spectrometer (TOMS) Program, which has been in ... Full description.

Statistics play a vital role in the scientific enterprise. This activity provides background information and tutorials on basic statistics (mean, median, standard deviation, etc.) used in science. Topics include descriptive statistics (measures of central tendency and dispersion) and presenting data (tables, figures, and graphs). Sample datasets from actual scientific experiments are used to illustrate ... Full description.

This two-part activity provides an introduction to the basics of measurement (linear, mass, volume, density) and discusses the role of inferential statistics in comparing any two measurements. The concept of random variations in measurements is introduced, which leads to a discussion of binomial distributions and probability in comparing measurements and results. Students will use online databases ... Full description.

In this activity, students investigate the effects of automobile pollution on plant growth by making measurements on two populations of leaves, one from within 10 meters of a busy road and a population of the same species situated more than 20 meters away. They will choose a method for measuring the leaves, create a table for their data, and test their hypotheses by performing a t-test. Full description.

This hands-on activity covers the basics of rock identification. After a brief discussion of the terms 'rock' and 'mineral', students will study the characteristics and classifications of the three major rock groups (igneous, metamorphic, and sedimentary). Using an online tutorial to test their knowledge and to learn more about rocks, they will identify 10 different specimens, record their observations, ... Full description.

Obesity is on the rise in the United States, due primarily to the size and composition of the American diet. Discussion topics include lack of exercise, changes in calorie intake over time, and environmental impacts of these increases in consumption. Each student will particpate in an activity in which they investigate how their own diets affect the agricultural demands of a hypothetical country. ... Full description.

This exercise is intended to reinforce the importance of Earth's atmosphere to living organisms. Topics include our bodies' interactions with the atmosphere; its composition and structure; and natural changes in the atmosphere (weather). Students will perform an actvity in which they are asked to observe and record weather conditions for four days, answer questions about their observations, and respond ... Full description.
