The difference between stalactites and stalagmites, and how both are formed, is the subject of a cross-curricular reading comprehension worksheet that asks kids to read the passage and then respond to comprehension questions based on the...

Class members explore the carbon cycle in the final installment of the 10-part Discover Your Changing World series. They play a simulation game where they walk through the steps carbon takes as it cycles through the different layers...

General facts about Earth's water sources, human use, and the water cycle are outlined by this presentation. Slide three has a grammatical error and slide nine refers to the local watershed of the author, so you will need to make a few...

With almost half of Americans relying on groundwater supplies, it is more important than ever to protect aquifers from possible contaminants. Working in small groups, young environmentalists explore this problem as they create an aquifer...

Get your hands dirty with a set of earth science activities! Class members delve into a hard-boiled egg to find the similarities to the earth's layers, create a papier-mâché model of the earth, craft a simulation of the earth's...

Ever wondered how an aquifer works? Introduce your class to the amazing way many people get water by exploring how underground aquifers work. Two fun hands-on activities are used to help kids understand what an aquifer is, how it works,...

There is the same amount of water on earth now as there was when it was formed. The water from your faucet could contain molecules that dinosaurs drank! Young scientists build their own hydrologic cycle model and observe...

Using a stream table, erosion enthusiasts examine how the density of sediment and how the slope of land contribute to the amount moved by waves. You will not be able to use this entire resource as is; there are teachers' names and...

In this reading comprehension learning exercise, students read a selection about dirt and soil characteristics. They answer 10 matching questions and 5 multiple choice questions based on the information given in the non-fiction article.

Fourth graders brainstorm the differences between the fossil fuels that people use in their transportation now and what they could use to minimize greenhouse gas emissions. They use a variety of techniques from webquests to writing...

Students examine rocks and minerals. Using the internet, students research rocks and how they are formed. They use word processing software to list minerals and materials that form specific rocks.

Students find the percent of oxygen in potassium chlorate. In this percent composition lesson plan, students heat a solution of potassium chlorate using a catalyst, manganese dioxide, to decompose the potassium chlorate and release...

Students investigate the three types of material stress related to rocks. They identify the three types of stress, conduct a simulation by breaking bars of soap using only their hands, and complete a worksheet.

Young scholars simulate the search for water in Mars using simple apparatus. In this space science lesson, students explain how soil temperature affects the cooling of probes. They graph the data collected from the simulation.

Students investigate questions centered around force and motion by going through the scientific process and creating fair tests and experimentation. In this instructional activity about forces-in-action, students diagram their findings...

Students compare and contrast the movement of objects on different surfaces, experimenting with friction and forces of motion. This friction lesson has numerous online tools including worksheets and virtual activities; the option is also...

Fourth graders explore the agents of erosion. They observe rocks that are rough and unweathered and record observations. They investigate rocks rubbed with sandpaper and ones that are not and the effects that the sandpaper has on the...

Students design and conduct an experiment to compare the water-holding capacity of sand, soil, and moss. They measure the change in weight for each material after adding the same amount of water to each material.

Students examine soil erosion and what causes it.  In this soil instructional activity students complete several experiments on soil erosion and the weathering process. 

Students examine soil. In this science lesson, students examine the layers of soil. Students collect soil from various locations and separate the layers. Students record and chart their findings.

Students compare the weathering of materials. in this weathering lesson, students experiment with the chemical and physical weathering of different materials. Students use salt and water as an example of how weathering occurs.

Students read and discuss the information that they read on the "Kentucky Coal, Reclamation and Subsidence." They then answer questions in reference to the reading. Some questions that students answer are: What is reclamation?, Name...

Students recognize different types of movement and causes that my affect the movement. They know that pushes and pulls are types of forces.

Learners investigate melting and cooling in a range of materials.
