This activity is a field investigation where students gather temperature and weather data in the a.m and p.m. and develop a new, experimental question to predict temperature over the course of the year.

This activity is a lab investigation in which students design and conduct experiments using pineapple juice containing the enzyme bromelain and its affect on the substrate gelatin found in Jell-O. The focus of student driven investigations are on enzyme specificity, activity and the impact of environmental factors on enzyme functioning. Based on the original activities from School Improvement in Maryland; "Pineapple/Jell-O Lab," Access Excellence Activities Exchange; "Enzyme Labs Using Jell-O" by Anne McDonald and Michael O'Hare, and AP & Regents Biology; "Lab 8: Pineapple Enzymes and Jell-O Molds" by Kim B. Foglia.

Spreadsheets Across the Curriculum module. Students use Polya's problem-solving heuristic to find the distance of a peak using vertical angles sighted from a wagon train heading toward the peak.

Use an astrolabe to measure the height of objects, and see seasonal changes over time.

Spreadsheets Across the Curriculum module. Students build spreadsheets to calculate the edge length of cubes and diameter of spheres of various rocks starting with their mineralogic composition.

Spreadsheets Across the Curriculum module. Students calculate the volume of the Great Pyramid and, following Napoleon, estimate whether its volume is large enough to make a wall around France.

This activity provides an opportunity for the student to collect data on their individual water use to set the stage for a unit on water resources.

Spreadsheets Across the Curriculum module/Geology of National Parks course. Students calculate an answer from a bathymetric map by summing volumes of vertical prisms.

This classroom activity presents Calculus II students with some Flash tutorials involving work and pumping liquids and a simple question concerning the amount of work involved in pumping water out of two full containers having the same shape and size but different spatial orientations.

This activity is an observational activity where students observe differnt fossils and predict what they are seeing and how old it might be.

There are 1 billion (1,000,000,000) nanometers in a meter. In this classroom activity students will gain an understanding of what that statement means.

Spreadsheets Across the Curriculum module. Students build a spreadshet to calculate grams solute to add to liters solvent to produce solution of desired concentration (mol/L).

This is an activity where students learn about inquiry by designing an experiment on bean plants with the goal of growing the tallest plant. Students work in groups to plan the growing conditions of the control and three experimental plants. Students collect data for about three weeks and analyze their data to see if their hypothesis is correct or not. The end product can be a report presented in a number of ways.

This activity is a center investigation where students learn about wind force using a fan/wind tunnel and objects.

Students explore a variety of objects to discover the many ways the objects move and what force makes them move.

SSAC Physical Volcanology module. Students build a spreadsheet to calculate velocity of rising magma in steady-state Plinian eruptions using conservation of mass and momentum.

This inquiry lab activity involves students working to understand the characteristics of electrically charged objects using common materials. Students will develop new testable questions.

Astronomy students learn how to use the Hertsprung-Russel diagram by plotting stellar data. HR diagram then reveals evolutionary stage of stars.

This film chronicles the introduction of the hula hoop, a toy that set off one of the greatest fads in United States history. According to Wham-O, the manufacturer of the hoop, when the toy was first introduced in the late 1950s, over 25 million were sold in four months. This short scene illustrates the difference between a movement along a demand curve and a shift of the entire curve, a subtle point that many students struggle with.

This lesson guides students to learn the science behind cloning, explore the benefits and consequences of human cloning, and communicate their knowledge and points of view. Students begin by reading an article titled Primer on Ethics and Cloning by Dr. Glenn McGee, available for free on the AIBS's ActionBioscience.org website. The lesson provides questions for the instructor to guide a class discussion about the article. Instructors can then choose from different activities to engage students further in this issue. One activity has students role play advisory teams providing information to a committee on the ethical issues of human cloning. The teams conduct research online, keep a journal recording their research paths, and answer questions in presentation format. Another activity has students researching and presenting information on human cloning. Through their research students can learn about cloning technology and related laws, as well as the perspectives of groups or individual scientist's viewpoints. Included are web site evaluation worksheets that are useful for student internet searches on any topic.
