This is a hands-on lab activity about the chemical composition and conductivity of water. Working in groups, learners will: conduct an experiment involving the process of electrolysis, prepare an experiment to better understand the process of ion... (View More)

Keywords: Electrolytes; Salinity
Audience: High school
Materials Cost: $1 - $5 per group of students

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 educational wallsheet illustrates Newton's First Law of Motion. In the related activity, students will discover the properties of inertia and motion, and see how they have very important real-life applications. The activity includes background... (View More)

This educational wallsheet illustrates Newton's Third Law of Motion. The accompanying activity is an experiment in which students create a balloon and straw rocket. Students must figure out how to shoot the balloon from the back of the classroom and... (View More)

In this activity, students learn about the molecular techniques used to study picoeukaryotes, and are led through a paper and pencil simulation of a Denaturing Gradient Gel Electrophoresis (DGGE) procedure performed on picoeukaryote DNA. The lesson... (View More)

In this lab activity, students examine phytoplankton and picophytoplankton under a microscope and learn how to use a stage micrometer to measure microscopic specimens. Resources needed include a microscope, slides, coverslips, a stage micrometer,... (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)

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)

In this 2-part inquiry-based lesson, students conduct a literature search to determine the characteristics of the atmospheres of different planets (Venus, Mercury, Mars and Earth). After collecting and analyzing data, student teams design and... (View More)

Students will time the flow of water through soils with different properties and measure the amount of water held in these soils. They will also experiment with the filtering ability of soils by testing the pH of the water before and after it passes... (View More)
