The purpose of this resource is to understand what causes the Earth's seasons with a focus on the Earth's tilt and spherical shape. Students learn how sunlight spreads over the Earth at different times of the year, emphasizing the solstices and the equinoxes. Students investigate the effect of the Earth.s tilt on the spread of sunlight by modeling different tilts using a three-dimensional polyhedron ... Full description.

This Internet-based collaborative project will allow students to share information about water usage with other students from around the country and the world. Based on data collected by their household members and their classmates, students will determine the average amount of water used by one person in a day. They will compare this to the average amount of water used per person per day in other ... Full description.

This on-line project is part of the Center for Improved Engineering and Science Education (CIESE) program, which has developed internet activities for the elementary, middle, and high school level student. Students measure the temperature, record the number of minutes of sunlight per day over a predetermined week, and determine their global coordinates. Each class then posts their data to this web ...

In this activity, students will become familier with the rock cycle. During the first part of the lesson, students work in small groups, each group having a copy of the rock cycle on a sheet of paper and a selection of small-scale samples and photographs that represent the products of the rock cycle. The students lay out their samples and photographs next to what they consider to be the correct boxes ... Full description.

This lesson uses a discrepant event to pique curiosity and provide an excellent metaphor for a problem in science that can be addressed in a scientific way. Water is poured into a magic box, and out comes a much larger volume of water (or other liquid). Students will learn that science is uncertain because scientists can make more than one workable model to explain their observations. Full description.

In this activity, students will learn to measure the density of various minerals. The activity will reinforce the usefulness of density as a physical test for identification of minerals. Using a selection of mineral specimens of varying densities, they will weigh each one in air, immerse it in a graduated cylinder of water, and measure the amount of water displaced by the specimen. Dividing the weight ... Full description.

In this lesson, students explore how groundwater contamination can spread through aquifers by participating in a groundwater plume simulation. They will learn how to determine the source of groundwater contamination, explore the possible contamination of Nevada groundwater by a major nuclear test site, and write a persuasive essay from the point of view of a Nevada resident living close to a groundwater ...

In this lab activity using M&M candy, students will explore the concepts of radioactive decay and dating. Students generate a radioactive decay table to simplify the math, use their data to plot a decay graph, develop the concept of half-life, and then use the graph to find the age of a mummified seal in Wright Valley, Antarctica. In a follow-up exercise, students will solve a mysterious Arctic ... Full description.

In this activity, students will be reminded that when sunlight strikes the Earth's surface, energy is absorbed and the surface material is heated. But although the same amount of sunlight strikes different materials at a given location, they heat up at different rates. Students will use models to demonstrate conduction, convection, and radiation and to gain an understanding about what happens to create ... Full description.

In this activity students design and execute an experiment through which they will learn the distinctions between density, buoyancy, and volume. Students are asked to imagine a staysail schooner loaded with mid-ocean ridge basalt as it floats in a swimming pool in Woods Hole. They must determine what will happen to the water level if all the basalt is dumped over the side into the pool. Posing an ... Full description.
