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.

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 construct a barometer to use in an experiment that they design to measure the air pressure on a daily basis. These observations of air pressure allow students to determine how weather is affected when a storm is approaching and...

Pupils explore Marjory Stoneman Douglas and her contribution to the ecosystems and National Parks.

Students observe and identify the changes that occur in the life cycle of a butterfly. They view photos of each stage of the life cycle, create an art project of the butterfly cycle, and illustrate a book titled "The Life of a Butterfly."

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 possible sources of water pollution, and explain the effects that water pollution can have on the food on the food chain. They Name human and other animal (i.e. fish) illnesses that can be contracted from drinking polluted...

The balance of nature can be a wondrous thing! With the 19th lesson of the 21-part series on systems, learners explore the cycle of photosynthesis and cellular respiration using a lab-based activity. Groups set up different test tubes...

Get your class outside to observe their surroundings with a lesson highlighting weather patterns and seasonal changes. First, learners take a weather walk to survey how the weather affects animals, people, plants, and trees during...

Young scholars identify the changing states of water, water vapor and ice in the water cycle They investigate how each of these stages can be reversible. Students complete a worksheet describing the water cycle.

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.

Fifth graders practice interpreting line graphs of the Hudson River water levels to assess the tides and tidal cycles in the estuary. They explore how weather can affect water levels and tides and observe that high tides and low tides...

Students are introduced to the processes of evaporation and condensation as they observe physical changes in water. They observe how matter changes from a solid to a liquid state. Students are explained that steam is water in its gaseous...

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 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...

In this life cycle worksheet, 9th graders complete 3 different procedures that distinguish viruses and bacteria and inherited characteristics. First, they read the background excerpt given about bacteria and viruses. Then, students cut...

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 investigate the cycle of life by observing tadpoles.  In this biology lesson, students utilize the Internet to read stories, observe pictures, and listen to sounds of frogs.  Students create a poster board collage...

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?

Using computers, Students work in small groups and progress through the roles of Explorer, Researcher, Designer, and Evaluator as they study the life cycle of plants, insects, butterflies and frogs.

Students study the nitrogen cycle and construct a diagram.  In this Earth Science lesson students use role play to see the various paths. 

Learners explore snow. In this forms of water lesson, students read a story about snow, identify the types of snow found in Alaska, and learn Inuit words for snow. The lesson calls for an Intuit Elder to visit the classroom as a guest...

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

Students explore the concept of the water cycle and how it affects flowing rivers. In this water cycle instructional activity, students talk about the effects that the water cycle and rainwater has on roads and sidewalks. They also...
