Curated OER
Investigation of Meiosis in Common Plants and Animals
Students 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.
Curated OER
Dishing the Dirt Part 1
High schoolers create a soil center on their school grounds. They begin to write in their science journals. They participate in an experiment that helps the community begin their own gardens.
Curated OER
Pollen Tube Growth
Students demonstrate the proper usage of the compound and dissecting microscopes. They identify the parts of a flower and the functions of the flower parts. Students describe the process of gamete formation and fertilization in a flower.
Curated OER
Stream Chemistry Monitoring
Students become familiar with real-world gathering of chemical data. The experience how the science is done: the nature of analysis, data collection, interpretation, and presentation. They study a nearby body of water for their experiment.
Curated OER
Mitosis And the Cell Cycle
Students determine the approximate time a cell spends in each phase of mitosis by counting cells in each phase from a prepared slide. They use a few simple calculations to estimate how long cells spend in each cycle in the body.
Curated OER
Inquiry-based Investigations into Pond Water Microorganisms
Students become familiar with common microorganisms and experience exploring the microbial world.
Curated OER
Flatworms- Observations of a Live Planarian
For this flatworm worksheet, students observe a flatworm in a petri dish. Kids describe the flatwork and measure the planarian. Students complete the various charts about the movement and observations of the planarian.
Curated OER
Seeing Cells
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.
Curated OER
Into the Pond
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.
