Students gather information from a variety of texts- literary and informational- to describe the connection between people, events, ideas, and pieces of information. Students are introduced to life cycles by learning about how a plant...

[Free Registration/Login Required] Through this unit, children learn that plants and animals reproduce as part of their life cycle and that in every life cycle there are distinct processes and stages. They should begin to understand how...

[Free Registration/Login Required] The teacher will use this lesson plan to review the life cycle of an apple.

Photorespiration is a wasteful pathway that competes with the Calvin cycle. Explore why photorespiration happens, when it's most likely to take place, and how it actually works.

Students explore what kind and how much bio-mass can be produced in an area around your city or town. They figure how many gallons of fuel can be expected from one acre of crop land, and how much carbon can be sequestered in the local area.

Site covers all aspects of plant reproduction such as life cycles, angiosperms and flowers. Provides links to other sites to aide in research.

Students analyze and explore visualizations and graphs that show the annual cycle of plant growth and decline. They investigate several regions in each hemisphere that have different land cover and will match graphs that show annual...

During this lesson, the classic story of Jack and the Bean Stalk will spark an interest in plants with students. Students will explore the Internet, take a nature walk, and make observations to learn more about plants. A brochure will...

This site traces the life cycle of the monarch butterfly and contains links for more in depth study of the terms presented.

Find out about the essential role energy plays in cell function and in sustaining life. Trace energy transformations as they pass from one living thing to another.

This is a good explanation of plant water balance issues and carbon fixing cycles. Transpiration processes are explained well with links to additional information.

This downloadable article addresses all aspects of nuclear energy. Visual charts make understanding of cycles and concepts easier. Most useful for older students and educators. PDF (requires Adobe Reader).

The engineers at Splash Engineering (the students) have been commissioned by Thirsty County to conduct a study of evaporation and transpiration in their region. During one week, students observe and measure (by weight) the ongoing...

Lots of information about the black carpenter ant. Learn about their physical characteristics, colonies, life cycle, food sources, and predators. A detailed chart listing many plants and animals permits exploration of their relationships...

Through multi-trial experiments, students are able to see and measure something that is otherwise invisible to them- seeing plants transpire. This information will allow students to consider how a plant's unique characteristics (leaf...

An activity where students observe the grounds around their school to study the plant and animal life cycle. Students will make a map of the school to keep track of their observations. Students will also compare their phenology calendar...

Article explaining what viruses are, their evolution, taxonomy, morphology, and replication. Also covers mechanisms by which viruses cause disease, how they can impact on plants, and the potential and real benefits we get from...

Extensive article on mangroves. Covers classification, physical characteristics, life cycle, habitat, economic value, and natural and human threats to their survival.

Background information on the history of photosynthesis. An explanation for how light is used to assist in making food for plants as the transfer of electrons allows energy to flow through the system.

This article discusses how plants and microorganisms, until recently, have mostly controlled how much carbon dioxide is released into an ecosystem, and explains how this process works. Humans' burning of fossil fuels has upset the...

This resource explains how the alternation of generations occurs in a plant's life cycle where sporophytes and gametophytes each play a role in plant reproduction.

A very simple introduction to the various types of growth and reproductive styles of common plants.

A great review for understanding life cycles and many aspects of living things. Find topics and their main ideas, vocabulary review, quizzes, and complementary activities for teachers to use.

In this self-directed activity, students use graphs and maps of lilac phenology data to determine the best time to host a lilac blossom festival in their area. A handout with everything the student needs to complete this lesson is...
