Curated OER
Looking Inside Cells
Seventh graders analyze and identify the role of the cell membrane and nucleus. They create flash cards to help them review cell structures. They also compare plant and animal cells.

MAKING THREE DIMENSIONAL PLANT AND ANIMAL CELLS
Students create two different cells, one plant and one animal. In this plant and animal cell lesson students form groups and construct a part of a cell. Students then put them all together to form one plant or animal cell.

Hands-on Cells
Middle schoolers review the components of a cell and the differences between plant and animal cells by creating a three-dimensional model of each type of cell. In small groups, they use modeling clay and household object to construct...

The Jelly Bean Problem
Students are challenged to eat some candy as a cell would need to do it. By solving this problem students simulate the cell process called endocytosis. They think about some of the problems that arise when a cell ingests food.

Plant And Animal Cells
Students identify parts of plant and animal cells and describe the functions of each part. They distinguish between plant and animal cells. After a lecture/demo, students perform experiments which help them construct models of plant and...

Rubber Egg
Students demonstrate the semi-permeability of a cell membrane. For this rubber egg lesson, students measure and record egg data, place the egg in jar with vinegar and close the lid, observe immediately and periodically for the next 3...

DNA Extraction
Learners participate in a lab activity in which they extract DNA from a strawberry. After mashing the strawberry into an even, smooth puree inside a bag, they add extraction buffer and mix the strawberry with the buffer. They filter...

DNA Extraction
Young scholars extract the DNA from a strawberry. In this DNA technology lesson, students describe what they think DNA looks like. They use a procedure to isolate and extract the DNA from a strawberry.

What Is an Egg Without its Shell?
Students observe osmosis, a cellular process that normally can't be observed without a microscope, and use scientific method to observe osmosis in a chicken egg.
