This is a hands-on lab activity about the composition of salt. Learners will explain the general relationship between an element's Periodic Table Group Number and its tendency to gain or lose electron(s), and explain the difference between molecular... (View More)

In this laboratory activity, students experiment with becomes CO² concentrations in water as a prelude to investigating the marine carbon cycle. The activity includes a worksheet and assessment questions. Tap water, ocean water (real or simulated),... (View More)

This is a hands-on lab activity about seawater density, specifically the relationship between density of fluid, weight of an object, and buoyancy. Learners will develop hypotheses and observe a demonstration of density to understand its role in... (View More)

These two hands-on labs are about the role of temperature and salinity in governing the density of seawater, a major factor controlling the ocean's vertical movements and layered circulation. In the first activity students work in groups to... (View More)

Students are introduced to classification through progressive activities. Initially, the teacher models the task by classifying buttons. Students then devise a classification scheme for paper clips. Subsequent activities use objects brought from... (View More)

This activity has two purposes: challenge the learner to develop a procedure for investigating a research question and to learn more about factors affecting the dynamics of air in motion. It demonstrates that warm air and cold air differ in weight... (View More)

In this activity, students will record a list of things they already know about hummingbirds and a list of things they would like to learn about hummingbirds. Then they will conduct research to find answers to their questions. Using their new... (View More)

The purpose of this investigation is to understand how the amount of water vapor in the air at various temperatures affects the way the human body responds. This is an important basic concept for understanding why one might feel either comfortable... (View More)

This experimental activity is designed to develop an understanding that air has mass. Students conduct an investigation and observe the change in the position of a bar balancing a balloon inflated with air on one end and a uninflated balloon on the... (View More)
