Learners describe how water exists on earth in three states. They trace the path that rain water follows after it falls. Students describe various forms that water takes on the earth's surface and conditions under which they exist....

First graders compare and contrast water from different sources. After collecting water from various sources, 1st graders create a list of observable properties of the water. Students then pour the water into a filter and observe the...

Students examine how global wind and water patterns aid in the spread of worldwide pollution. In groups, they read articles about the domino effect of pollution and create posters displaying its journey. On blank world maps, students...

Third graders investigate the stages of animal life cycles. They examine an egg and compare it to an inanimate object, read a booklet about the life cycle and define key vocabulary terms, and observe a mealworm. Students then design a...

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.

High schoolers gather mosquito eggs to record the mosquito life cycle using drawings, descriptions, and any other appropriate means. In small groups, they analyze and describe the process of complete metamorphosis. They classify...

Students perform several water quality tests on groundwater from their area. They use test strips to determine the pH, hardness, alkalinity, nitrates, iron and chloride levels.

First graders discuss the book The Lorax and research what living things need. In this environmental lesson, 1st graders investigate how humans affect the growth of plants. Students conduct an experiment with sunflowers.

Students complete a series of activities in which they study atoms, molecules, and the presence of atmosphere. They study the water cycle and the Greenhouse Effect by investigating and completing handouts.

Even rivers have tides. Older elementary schoolers will discuss the Hudson River and how weather, water craft, and the ocean cause tidal fluctuation. They will examine a series of line graphs that depict tidal fluctuation, then analyze...

Students draw and label the four parts of a plant. They describe changes that are part of the common life cycle. Students follow various one and two step directions. They are asked to discuss that they can recall about plants.

Student learns about the life cycle of plants by watching a time-lapse video. This activity provides learners with further evidence that all living things grow and change as they progress through their life cycle.

Students explore the physical properties of water. In this water lesson, students explore water as it changes states. They observe, measure and use communication skills to describe change.

Students participate in numerous activities to gather information about parts of the life cycle. In this life science lesson, the teacher choose from a number of activities to create or support an interdisciplinary unit about the life...

Pupils measure the heat of physical and chemical changes in reactions.  In this chemistry lesson students determine at what extent changes emit or absorb heat. 

In this water and Earth activity, students read a 2 page article on water and the Earth, name the clouds in 2 pictures and then list 4 sources of water in nature.

Sixth graders study the effect of pollution in our food chains. In this plant biology lesson, 6th graders first experiment with pollution by placing a carnation in colored water. Next they use a food chain triangle to see the...

Take an in-depth look at nutrient loading, eutrophication, and hypoxia using data on The Chesapeake Bay as an example. This comprehensive presentation includes detailed graphs, photos, and details about the changes in marine organism...

Guide your students through the process of opening up a frog. The resource provides step-by-step instructions for dissecting a frog, as well as guiding questions to answer throughout the lab.

Students investigate the weather by reading children stories.  In this weather observation lesson plan, students read Cloudy With a Chance of Meatballs and several other stories about weather before they create a KWL chart....

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

In this science learning exercise, students read about temperature and thermal energy in a hurricane. Students also draw their own hurricane and label 5 different parts.

High schoolers examine the hydrologic impacts of drought. Humans can change the course of the water cycle, to some extent, to meet their needs, but can they do so without imposing risks on the plants and animals?

Students explore how temperature affects the processes of evaporation and condensation.
