Students (females) are introduced to the cell. They discuss what a cell is, and students define what a cell is. Students comprehend that all living things are made up of cells. They comprehend that life is defined as something that...

Students discover the microorganisms that live in water. They study the structures and life functions of protists and recognize the similarities between them and multicellular organisms.

For this life cycle workbook, 3rd graders complete several different activities in which they analyze different invertebrates, identify arthropods, examine human biology and plants, and study natural environments. 20 different...

Students explain why dissolved oxygen is important in aquatic ecosystems. They evaluate the optimal dissolved oxygen levels for living organisms.

Students create and observe coacervates. In this origin of life lesson, students create coacervates by mixing carbohydrate and protein solutions. They observe the life-like qualities of the structures and discuss the origin of life.

In this science worksheet, students use the diatoms present in water in order to test water quality and perform data collection and interpretation.

Learners explore biology by identifying a diagram. In this cell anatomy lesson, students read a story about archeology and conduct a fictitious archeology dig in class in which they search for animal cells. Learners define a list of...

Learners explain the concepts of what DNA is and where it is located in a cell, identify the two types of molecules that make up the rungs of a DNA molecule and identify the two types of Purine and Pyrimidine molecules

In this cell phases worksheet, 7th graders study the phases of an onion cell. Students write the onion mitosis cell phases on the lines.

Young scholars witness various stages of mitosis through preparing onion root tip slides. With teacher guidance, they learn a great deal through the hands-on process of preparing the slides themselves.

In this human cells worksheet, 7th graders complete a science experiment using human cheek cells. Students sketch the cells at high and lower power and label the cell nucleus, cytoplasm, and cell membrane.

Sixth graders explore the internal organs of grasshoppers. They determine the function of the organs through a dissection activity.

Students become familiar with common microorganisms and experience exploring the microbial world.

In this flatworm learning exercise, students observe a flatworm in a petri dish. Students describe the flatwork and measure the planarian. Students complete the various charts about the movement and observations of the planarian.

Students explore how to classify new species.

Sixth graders study living cells and their functioning units.  In this cell lesson students color cell diagrams, answer questions and discuss the differences between plant and animal cells. 

Seventh graders use a pond to explore macroinvertebrates and other organisms. They use a dichotomous key to classify the organisms and maintain a journal recording their findings.
