When it comes to the carbon cycle, the sky really is the limit. The lesson begins with observing a closed ecosystem in a bottle. Then, scholars discuss and answer questions on the carbon dioxide and oxygen cycles. 

Learners recognize that all living things are made up of cell and that they cannot easily be seen by the naked eye. Students become familiar with the use of microscopes as a tool for investigation.

Students examine climatic effects on ecosystems. They plant tomatoes and observe the differences in plant growth with differences in light. They create picture collages of plants, animals, and insects found in each climate of the U.S.

Students explore the function and structures of cells, including plant and animal cells. They explore cell parts including cell wall, ribosomes, chromosomes, nucleoid, plasmids, flagella, pilli, and plasma membrane, cel

Seventh graders analyze and identify the role of the cell membrane and nucleus. They create flash cards to help them review cell structures. They also compare plant and animal cells.

Students apply skills they have learned to construct an accurate model of the Brassica and then work together on a group project. They analyze how the parts of a system go together, and how these parts depend on each other. Finally,...

Students investigate living organisms and define the properties of a living species.  In this life characteristic lesson, students examine plants in their class and discuss whether or not they are alive.  Students create a...

Fourth graders explore the pollination process. In this plant biology lesson, 4th graders dissect a flower to identify the parts of a flower and watch a video to see seed dispersal. Students write about the pollination process.

Students create a miniature rainforest ecosystem, a terrarium. Students then explain how the continuous flow of energy and food in the ecosystem allows it to sustain itself.

In this cell learning exercise, students access a given website to compare the cell organelles and their functions to jobs in a factory. This learning exercise is a graphic organizer.

Students explain how the components of a cell operate as a system. Students examine a bicycle and find out if parts were arranged differently, could the system still be carried out. They look at cells as well and see what function they...

Students discover how environmental factors impact the survival of a population. In this landscape design lesson, students create a new animal and discuss the relationship between the animal and its environment before creating a habitat...

Students create simple 2D concept driven visualizations of cells and cell organelles and organize them into an effective presentation.

In this science worksheet, students learn facts about plankton by reading two pages of factual information. Students read about the different kinds of plankton and how it is classified. Detailed drawings are included. There are no...

In this online interactive science quiz worksheet, students respond to 4 multiple choice questions about stem cells and their functions.

Students explain the difference between dominant and recessive genes, identify what causes differences in the traits of parents and their offspring, and explain how sex is determined. They will also improve their reading and...

Young scholars complete internet research in small groups to identify types of water pollution, spotlight water pollution hot-spots, and design a plan for water prevention.

Students organize picture cards of the sequene of how food gets from a farm to their home. They then sequence cards of how coffee grown in Colombia gets to their home comparing the differences.

Students study soil, living and non-living particles in the soil, and learn about composting. In this soil study lesson, students study soil samples and discuss the living and non-living components of the soil. Students classify the...

Learners identify the purpose of cellular mitosis. They work in groups of four to use images of animal and plant cell mitosis to illustrate each step in the mitosis process on their graphic organizer.

High schoolers explore biology by researching living cells. In this living organism lesson, students participate in a role-playing activity in which all the high schoolers in class form one plant cell by portraying specific parts of a...

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 research what food is eaten by the following organisms: penguins leopard seals, krill, elephant seals, petrels, albatross, fur seals, squid, insects and grass. They make a food web using the data they have gathered.

Learners study vitamins and who should take them and what ones to take.  In this investigative lesson students plan a healthy diet after reviewing the types of supplements.
