This is a hands-on lab activity about evaporation. Learners will conduct experiments to observe the process of evaporation. They will then describe the process of evaporation, and the general water cycle, through discussion and pictures. Background... (View More) information, common preconceptions, a glossary and more is included. This activity is part of the Aquarius Hands-on Laboratory Activities. (View Less)
This is a hands-on lab activity about seawater density. After developing a hypothesis, learners will conduct a simple investigation of density. They will discuss changes in density observed and describe how salt affects the density of water.... (View More) Background information, common student preconceptions, a glossary and more is included. This activity is part of the Aquarius Hands-on Laboratory Activities. (View Less)
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) buoyancy. They will also examine the effect of salinity on density. Background information, common preconceptions, a glossary and more is included. This activity is part of the Aquarius Hands-on Laboratory Activities. (View Less)
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) and this difference affects air's vertical movement in the atmospheric column. Resources provided to students for this challenge include a homemade balance beam made of wood, two paper bags, a desk lamp, paper clips, tape and a thermometer. The resource includes background information, teaching tips and questions to guide student discussion. This is the chapter 8 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.

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 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 a lesson about infrared radiation. Learners will investigate invisible forms of light as they conduct William Herschel's experiment and subsequent discovery of infrared radiation. They will construct a device to measure the presence of... (View More) infrared radiation in sunlight, explain that visible light is only part of the electromagnetic spectrum of radiation emitted by the Sun, follow the path taken by Herschel through scientific discovery, explain why we would want to use infrared radiation to study Mercury and other planets, and explain how excess infrared radiation is a concern for the MESSENGER mission. This is activity 1 of 4 at the Grade 5-8 band of "Staying Cool." (View Less)
In this activity, learners will determine the factors affecting the appearance of impact craters and ejecta on the Moon. Extensions are listed. This activity is in Unit 2 of the Exploring the Moon teachers guide, which is designed for use... (View More) especially, but not exclusively, with the Lunar Sample Disk program. (View Less)

This is a lesson about planet formation. Learners will observe and describe differentiated samples in the Meteorite Sample Disk (or photographs), conduct experiments to model the separation of light and heavy materials within a planetary body,... (View More) relate meteorites to the core, mantle and crust of asteroids, and model the break-up of differentiated planetary bodies to expose the interior layers. Materials lists, and advanced preparation and procedural tips are included. This is lesson 11 of 19 in Exploring Meteorite Mysteries. (View Less)
Materials Cost: $5 - $10 per group of students
This is a lesson about the connection between meteorites and asteroids, focusing on remote-sensing techniques using light. Learners will make and record observations and measurements; analyze data and draw analogies; compare samples; measure and... (View More) record the brightness of spectral light; discover the composition of white light; participate in introductory quantitative spectroscopy experiments; set up, conduct and analyze a reflected light experiment; and recognize/discover that different materials reflect different proportions of incident light. Activities, vocabulary words, and experimental extensions are included. This is lesson 5 of 19 in Exploring Meteorite Mysteries. (View Less)
