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.

Students 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 mosquitoes...

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 pupils 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 plan, 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...

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

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...

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

Students 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...

Students 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.

Students are shown how dissolved oxygen enters the water. They are taught the difference between a water sample that has been exposed to the air and one that has not. Students brainstorm what organisms need to survive. They use dissolved...

Third graders investigate the life cycle of the Monarch butterfly. They experiment with various tools to simulate the mouth parts of insects, conduct research, record their observations of butterflies hatching, write a play, complete...

Students chart how milkweed bugs grow and change.  In this growth and life stages lesson, students read two stories and discuss how and why things grow.  Students brainstorm what can be measured about humans, review and discuss...

Learn about the factors that affect the way oxygen dissolves in salt water with a chemistry lab. After studying the molecular structure of water, young scientists figure out how aeration, temperature, and organic waste affect...

Students conduct experiments designed to detect the presence of CO2 by using a BTB that changes color (blue to yellow) in the presence of CO2. First, students experiment with the CO2 from combining vinegar and baking soda. In part two,...

Students determine

Tenth graders study the major hurricanes of the Atlantic Ocean. In this weather lesson, 10th graders read an article and answer various questions. Students discuss their findings with their classmates.
