Fourth graders graph the percentages of the materials that make up the Earth and complete computations based on their results.  For this topsoil lesson, 4th graders diagram the different layers of Earth's composition.

Students discuss caves. In this science lesson, students experiment with how dissolution, a chemical weathering process, leads to the formation of caves. Once the cave is finsihed students draw a picture or describe in writing what it...

Pupils 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...

Second graders conduct experiments with rocks to observe weathering. They read books, examine websites and watch a video to examine how rocks break down into soil.

In this reading comprehension worksheet, students read the noted section in their science textbooks and respond to 4 short answer and 3 fill in the blank questions regarding fossils embedded in rock formations.

Students identify plants parts and their functions.  In this plant cycle lesson, students examine parts of plants and how the parts help them survive in its environment. Students use graphic organizers, the internet, books and...

This PowerPoint provides a multiple choice and fill-in-the-blank format for reviewing vocabulary and related content following an "earth's crust" science unit. The information is concise and age-appropriate and the font and colors are...

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 research about the chemical processes involved in cave formation. In this chemistry activity, students draw or find a cave picture with stalagmites and stalactites online. They write a brief caption and share them with the class.

Young geographers examine how Crowley's Ridge was formed. This is one Arkansa's six natural geologic divisions. The history of Crowley's Ridge is important in that the first settlers of the state were attracted to this region, and it...

Learners sample goodies from an unseen ocean floor and try to accurately describe their composition. This simulation helps students explain the limitations of sampling and the problem of obtaining representative samples of sea floor...

Students study the change in land formations due to water erosion. They work in groups to build a model of a mountain that will be composed of materials that will best withstand water erosion.

Students propose and perform an experiment using the scientific method. The purpose of the experiment is to discern some earth materials or combinations of earth materials that best increases the pH of "acid rain". From the results of...

Students explore botany by participating in a calendar class activity. In this plant observation lesson, students examine a diagram of a Brassica plant and identify its anatomy before planting their own seeds and viewing the changes over...

Pupils take plants of their own choice and pollute the soil with a pollutant of their own choice or one assigned by the teacher. They regularly record observations such as plant growth, health, and soil pH.

Fourth graders make a detailed observations about non-native and native grasses. They define reasonable policies that they expect to follow while working in the CRWA. Students list, in small groups, two treatments that have been used in...

Students describe the movement of water within the water cycle and identify the states of water as it moves through the water cycle.

Fourth graders explore insect life by viewing a soil presentation in class. In this composting lesson plan, 4th graders read assigned text about the process of composting soil and the necessity of soil in plant life. Students view video...

An extensive investigation of the Earth's climate changes awaits your environmental science classes. This top-notch presentation begins by looking at the history of Earth's climate and then predicts the impact on each major terrestrial...

Young gardners read and listen to books about seeds, plants, and the growing process. They plant seeds in plastic cups to observe the process of root-growing and plant formation. The whole class walks through a field to collect seeds...

Pair earth scientists up to use an amazing online arctic portal mapping tool and Google Earth to analyze permafrost changes. They compare changes to data on atmospheric concentrations of methane to see if there is a correlation. Then...

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...

This slide show progresses through a comprehensive review of the grounding principles of earth science. Get down and dirty with the details of fossil fuels! Help your geologists to have a rock solid understanding of the rock cycle. The...

This clever activity combines elements of geography, art, literature, and storytelling. Pupils take a close look at the six geographical regions of Arkansas, and pay close attention to Crowley's Ridge - which is one of the six. In...
