In this hands-on activity, students will extract DNA from fruit. Students will learn where DNA is found, how it is extracted, and what it looks like.
- This activity should be used after cells and DNA have been discussed. Students need background knowledge on where DNA is stored, its structure, and its role within organisms.
- Before the activity, it may be a good idea to ask students to predict what they think the DNA will look like.
- After the activity, a recap for closure may help students understand what they have seen.
Here are some suggested questions for discussion:
o Did the DNA look as you predicted?
o Why did you need to crush the fruit?
o Which step in the procedure allowed you to see the DNA?
