Making a Battery
Don't be shocked when your class has a blast making their own batteries! Science scholars examine a dry cell battery, then design and construct a wet cell battery. The activity guides them through the parts of a battery, the variables...
Curated OER
Cell Project
Young scholars investigate cells. They discover what cells are, where they are found, what they do and what they are made of. They construct a giant cell that is posted on the bulletin board.
Curated OER
Cell Observation Exercise
Learners take measurements of the distance between the objective and the slide when in focus with each objective. They determine the diameter of the field of view at each power in order to determine the size of the cells being observed.
