Students examine a frog's life cycle. In this amphibians lesson, students read a book about frogs and discuss how frogs are born and how they grow.  Students complete worksheets on the life cycle of the frog, and hold a discussion...

Learners examine the life cycle of the butterfly through literature. In this butterfly life cycle lesson, students listen to a read aloud of Eric Carle's, The Very Hungry Caterpillar, and discuss the life cycle shown in the story. They...

Second graders study Earth's materials. In this air and weather lesson, 2nd graders note changes in the weather and examine tools that help us study the weather. Students analyze how changes in the environment make changes in the...

This project is designed so students can learn about the sources of water, the path it takes to get to homes and businesses, and the ways we use water. Students will begin by expanding their awareness of the hydrosphere as they research...

Third graders discuss the sources of water, the path it takes to get to homes and businesses, and the ways we use water. Students begin by expanding their awareness of the hydrosphere as they research the water cycle, the sources of our...

High schoolers use a digital atlas to explore the effects of water on landscapes. They view view pictures and complete worksheets to study the properties of water. Students study the water cycle and the chemical role it plays in living...

Learners observe the amount of water in an open container over time, and they observe the amount of water in a closed container over time. They compare and contrast the sets of observations over time.

A lab activity is a great way to incite thoughtful questioning and scientific processes. Pupils will collect organisms with a Petri dish, make observations, sketch the organism, ask questions, then attempt to identify the specimen...

The Very Hungry Caterpillar is the inspiration for this project-based learning activity. Kindergartners create a lifecycle chart for a butterfly with four sections: egg, caterpillar, pupa, and butterfly. It is a three-dimensional...

After a reading of Lois Ehlert's Planting a Rainbow, class members plan a rainbow garden, research growing cycles of the fruits and vegetables in their section, and then plant and maintain the garden.

Students explain that ants are an important element of nature's balance. Ants eat many insects and are food to other animals. They watch a video and conduct hands-on activities that give them an excellent overview of the ants role in...

This project provides students the opportunity to investigate parasites as a possible cause of the observed frog deformities. It asks students to view web-based evidence and interpret whether it supports the parasite hypothesis. Students...

Take a field trip to observe Koalas, absolutely! Budding scientists become familiar with the Koala's position in the food chain. They answer questions based on what they see and draw a food chain explaining the Koalas position. Tip: A...

Fish are no different when it comes to a living being's primary objective—to reproduce. They do differ, including from fish species to fish species, in their life cycles, survival tactics and reproductive strategies. After discussion of...

Second graders receive an introduction to the rock cycle. They dicuss the geologic rock cycle. They create a simulation of a sedementary rock.

Middle schoolers identify local watersheds and drainage areas by using maps and other resources. They are given copies of the water cycle. Students discuss the movement of water in the environment. They observe, record and transfer...

Learners experiment to discover how different variables affect the water cycle. They do hat flow experiments and construct a computer heat flow model.

Third graders observe various demonstrations dealing with the water on our earth, such as a comparison of the amount of salt water and fresh water on earth, then participate in a role playing activity in which they become a molecule of...

Students bag trees to determine the mass of the water given off in the evapotranspiration process.

Students participate in a hands-on activity that demonstrates how the water cycle functions. Students look specifically at condensation and evaporation during the recycling of water.

Students examine how natural processes change the earth by identifying their local water cycle. Individual students complete a cloud journal over a specific period of time. They observe clouds daily and take photographs of the clouds...

Students study the meaning of a water table and how it contributes to the existence of streams, swamps, and lakes in Nebraska. They conduct an experiment and complete a diagram of the hydrologic cycle.

Sixth graders identify the steps of the different cycles of matter, while learning to use WP utilities.

Second in a three-part instructional activity on rivers, this instructional activity focuses on the flooding that occurs in riparian locations. First, learners take a look at facts about the Amazon River. They read online materials and...
