How Cells Duplicate and Why Where Something Can Go Wrong
Seventh graders explore the function of a cell and cell division. In this investigative lesson students construct a 3-D model of a DNA molecule.
Curated OER
Chromosomes
Students study chromosomes and how molecular half life affects them. In this chromosome instructional activity students complete several lab activities on calculating half life, and cracking alkanes.
Curated OER
How Atoms Work
Students explore the concept of atoms and how they combine to form molecules and compounds. In pairs, they read an article on how atoms work and discuss the main points. They draw atoms and write a paragraph about their elements.
