Product Description
Have you ever wondered what DNA looks like? In this activity, students are going to break apart the cell membrane of a strawberry and separate the DNA from the nucleus. They will get to see and touch actual DNA! Strawberries are easy to use because they are soft, easy to pulverize and they are octoploid, which means they have eight of each type of chromosome.

This activity is done after we have already completed the genetics unit and have learned about plant and animal cells. Students should already have an understanding of the different cell organelles, the differences between plant and animal cells, and how to use a microscope.

As a result of participating in this activity, students will know how to extract DNA from strawberries, observe what DNA looks like to the naked eye and under a microscope, and understand that DNA is found in all food we eat.

Students will work in a group of two and will use the provided materials to conduct an investigaton, make and record observations, view a sample under the microscope and answer analysis questions.
