Maximum Power Point
Pupils investigate how to optimize the power output of a photovoltaic cell using a home-made gnomon stand. They use data collected to create current-voltage and power-voltage curves to determine the "maximum PowerPoint," (MPP) at which...
Curated OER
Introduction to Biology
Students study cell theory and the link between it and technology. In this cell theory lesson students examine the importance of cell theory.
Curated OER
Liver
Students study the livers parts and functions then follow a lab experiment to watch first hand how the gut uses bile to physically break down fatty substances into smaller pieces.
Curated OER
Reproductive System
Fifth graders identify and define parts of the reproductive system. In this health activity, the teacher introduces the parts of the reproductive system, then students match body part cards to the corresponding definition cards.
Curated OER
Meiosis
Students practice identifying the stages and purpose for meiosis. They use a worksheet to construct each phase, label its parts and describe the process occurring in each phase. they divide the process into meiosis I and meiosis II.

Cell 9 Edited: Meiosis
Student list the steps of mitosis with a brief definition of each stage. Then they begin their study of meiosis. They practice placing the stages of meiosis in order using flashcards depicting the Prophase, Metaphase, Anaphase, and...
Curated OER
Organelles
Pupils explore the functions of major eukaryotic organelles. They compare and contrast prokaryotic and eukaryotic cells. Given diagrams and drawings, students take turns drawing structures, discussing their function, and labeling each...
Curated OER
DNA and Protein Synthesis in the Cell
Students explore how DNA fits into chromosomes and how chromosomes relate to the human body. They learn about DNA replication and protein synthesis and model these two processes in Web activities.
Curated OER
The Way a Tree Works
Students explore nature by conducting botany experiments. In this plant life lesson, students define the necessary resources for a plant to thrive on our planet while defining scientific vocabulary terms. Students utilize different plant...
