In this lab, students will demonstrate observation skills as they design an experiment to separate colors of various water-based pens in order to learn about mixtures and solutions. Students will determine a variable to test and complete...

This site provides a pair of activities to demonstrate convection currents in air and water. Encourages students to view air as a fluid.

Sixth graders predict if different types of coke will float or sink.

The atmosphere forces the ocean in three ways: addition and removal of heat, precipitation and evaporation, and wind stress. The former two processes influence the density of sea water. Gravity acts on these density differences to cause...

Extensive site for teachers provides some helpful resources that pertain to plant and animal cells. Includes a microscope diagram as well as plant, animal and pond labs. Also contains links to structures and mechanisms, matter and...

For this activity, students will investigate how temperature and currents affect the salinity of ocean water, making predictions after studying ocean maps. It is recommended that teachers do the experiment themselves before presenting it...

An experiment to determine if either a regular or a diet can of soda will float or sink when placed in water, and what causes this.

In this activity, students will observe that a change in the temperature of air will determine its place in the atmosphere. Water, which behaves very similarly to air, is used in this demonstration. It flows in fluid currents in a visual...

[Free Registration/Login Required] This flipchart is a multi-subject themed primary unit around the concept of oceans. Reading, Math, Science and Social Studies activities revolve around an ocean theme. In Part 5, students work on...
