In this soil learning exercise, students find words that represent soil words in a word search. Students search for 9 words in this word search.

Students examine the most common characteristics of clay and sand, and to understand how the properties of these materials affect the erosion of the landscape and the formation of the many landforms. They explore clay and sand through...

Fourth graders observe and identify the effects of geological activities and weathering on Earth's surface. They also take a look at reports of events such as storms, earthquakes, floods, and volcanoes. There is a hefty hands-on activity...

Learners discover soil characteristics and how it is formed on Earth and the Moon by examining local samples to a lunar simulant. They replicate the effects of wind erosion by scraping dry bread with sandpaper. Students use rocks and...

Students use stream trays covered in different types of rocks or soil to investigate infiltrates and runoff. In this water pollution instructional activity, students work in groups with stream trays that have different substrates. They...

Students simulate some of the Pathfinder experiments by devising methods of collecting and measuring magnetic substances in pseudo-Martian soil. The efficiency of each of the methods used to collect materials is evaluated in this lesson.

Fourth graders investigate how glaciers cause the weathering of landforms. They observe a brick that has been placed on a frozen slab of ice, and discuss the results, comparing them to the movements of a glacier. In small groups, they...

Students investigate craters and marea. In this crater and marea instructional activity, students conduct an experiment to create craters. Students participate in a dance activity.

Students understand the dynamics of acid rain and its impact on the living and non-living environment. They hypothesize how acid rain affects water pH levels in two lake systems with differing watershed features.

Students relate the states of matter and clouds.  In this environment lesson, students create a chart of information they know about clouds.  Students put an ice cube in a bag and tape to a window. Students watch for...

Students discuss the causes of global warming. For this earth science lesson, students examine how global warming is connected to the arctic and world climate. They write a paragraph about their interconnection.

Learners watch a classroom demonstration, and experiment to discover the five ways that Earth's crust shifts along a fault.

Students explain how the earth makes fossils and how dinosaur remains become fossils. In this Bringing Dinosaurs Back to Life instructional activity, students solve paleo-puzzles which ask students to solve problems as if they were...

First graders listen to the book The Story of Sand and make predictions about an investigation based on soil, sand, and silt. In this sand lesson, 1st graders work in groups to discuss their observations about sand and answer higher...

Students identify and count Macroinvertebrates at a Hydrology website.  In this macroinvertebrates lesson students collect, sort and identify Macroinvertebrates.

Students predict from a rock sample whether a water well could be drilled in that type of rock. They predict what conditons would be necessary for the well to produce water.

Pupils explore the process of estivation, hibernation and torpor and the ways that frogs adapt to seasonal weather changes.

In this tundra worksheet, students read about tundras and the plants and animals that live in tundras. They then use what they learned to answer the 10 questions on the page. The answers are on the last page.

This PowerPoint provides a game show format with multiple choice questions about fresh and salt water. Topics include sources of water, water geography, uses of water, and the water cycle.

Students create a web connecting global warming, the Arctic, and wold climate. They write a paragraph explaining the role of the Arctic in world climate.

Learners sequence the steps leading to the formation of rain, and design a model to represent these steps. This task assesses students' abilities to classify, generalize, infer, interpret and communicate data, and construct a pictorial...

Students discuss global warming, greenhouse effect, permafrost and other key words.  In this climate instructional activity students create a web that connects global warming, the Arctic and world climate then write a paragraph...

Students explore the Earth and its ability to support life. They discuss the geosphere and the water cycle and complete the Water Wonders activity. After completing the activity, they respond in their journals and reflect upon the...

Students use counting skills to decide who wins the Classroom Winter Games. They use numeral writing and tally marks to keep score. Students have an opportunity to pretend they are competing for medals in the Winter Games while using...
