This activity provides a visual example of convection in fluids. Students will record their predictions and observations on diagrams of the experimental set-up showing convection currents. Materials required include hot and cold colored water,... (View More) thermometers, stopwatch, and index cards. This activity is part of the MY NASA DATA Scientist Tracking Network unit, designed to provide practice in accessing and using authentic satellite data. (View Less)
In this inquiry exploration, student design an experiment to test the absorption of heat by different earth materials. Materials required include plastic water bottles, soil, sand, water, thermometers, lamp with 60 watt bulb, and stopwatch. This...

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) other end. Resources needed include a piece of wood, two rubber balloons, two large paper clips, ruler, nail, hammer and tape. The resource includes background information, teaching tips and questions to guide student discussion. This is chapter 7 of Meteorology: An Educator's Resource for Inquiry-Based Learning for Grades 5-9. The guide includes a discussion of learning science, the use of inquiry in the classroom, instructions for making simple weather instruments, and more than 20 weather investigations ranging from teacher-centered to guided and open inquiry investigations.

In this hands-on activity, students create a model soil profile in a two-liter beverage bottle, time the movement of water through different soils and observe the amount of water held in these soils. They observe the filtering ability of soils by... (View More) noting the clarity of the water before and after it passes through the soil. The activity is supported by a student data sheet. This is a learning activity associated with the GLOBE soil investigations and is supported by the Soils chapter of the GLOBE Teacher's Guide. GLOBE (Global Learning and Observation to Benefit the Environment) is a worldwide, hands-on, K-12 school-based science education program. (View Less)

This learning activity engages students in measurement of pH in water and soil samples, plants and other natural materials. By mixing different substances, they observe how pH changes, and become familiar with the pH of common household products.... (View More) Through discussion, they learn how pH can be modified in the environment. (View Less)

This is an activity about magnets and magnetism. Learners first make predictions about magnets, such as a list of the types of materials a magnet will pick up, how a magnet can be made, and how a compass can be made. Next, learners test their... (View More) predictions using simple experiments, and, finally, reflect on their predictions. This is the second activity in the Mapping Magnetic Influence educators guide. (View Less)
In this introductory classroom activity, students exercise their scientific skills of observation and deduction as they use their senses and simple laboratory assays, such as pH indicator paper, to identify mystery pollutants in water samples.... (View More) Activity includes a student worksheet. This is a learning activity within the Hydrology chapter, GLOBE Teacher's Guide. (View Less)
Learners will understand some of the geological processes and the structures that form as lava flows across planetary landscapes by using mud as an analog for lava. This activity is in Unit 2 of the "Exploring the Moon" teachers guide, which is... (View More) designed for use especially, but not exclusively, with the Lunar Sample Disk program. Note a large piece of plexiglass or other non-porous surface is required. (View Less)
