Seventh graders engage in a lesson that is concerned with the basic structure and function of the cell. They systematically cover the different parts of the cell that includes active transport, organelles, mitosis, and meiosis. The...

In this chromosome worksheet learners complete a crossword puzzle by answering questions on DNA, nucleic acids, nucleotides and RNA.  

Students identify and define several related vocabulary terms. Students complete a short lab and complete the questions. Students create a cell crossword puzzle and play cell computer games through the included links.

Students define the key terms that are the structure and function of DNA. In this genetics lesson students complete a lab activity in which they construct a model DNA structure.

For this biology worksheet, students complete a crossword puzzle with 39 questions on taxonomy. They identify the different classification systems used in biology.

Young scholars list the parts of cell theory and describe and define vocabulary.  In this cell lesson plan students complete a handout that includes sketching a cell. 

A three-page quiz assessing budding biologists' understanding of classification. Middle-level learners may need a little additional time on this, but should be able to handle the concepts with ease.

Students investigate the concept of bioluminescence. They use dinoflagellates in a lab situation to study photosynthesis. They conduct research into the concept using a variety of resources. Also the class is taken on a field trip to...

In this science learning exercise, students look for the words that are related to the concept of zoology that is reviewed in the sheet. They also acquire new vocabulary.

Learners are introduced to Gaia theory of natural homeostasis. They graph Earth's temperatures over time, construct terrariums or monitor the outdoor environment. Related videos titles are suggested, but may be outdated. The objectives...

Students describe the characteristics of algae. In this biology activity, students perform a series of experiment to explore algae. They investigate the basic things algae need to survive.
