STEM Storytime – Strawberry DNA
Join Let's Talk Science Outreach to read Nicola Davies' book, "Grow: Secrets of Our DNA" and complete a hands-on science activity about DNA!
Students will learn the basics about DNA and how it is the fundamental blueprint for all living things. Using everyday household items, students will conduct an experiment that allows them to see the DNA of a strawberry.
For this activity, students will need:
-2 ripe strawberries (frozen is fine, but let them thaw beforehand)
-1/4 cup water
-1 tablespoon dish soap
-1 teaspoon salt
-1 tablespoon ice-cold rubbing alcohol (70% isopropyl alcohol)
-coffee filter or strainer or paper towel
-plastic zipper-lock bag
-2 small clear cups or bowls
-tweezers or popsicle stick or bamboo stick, etc.
-measuring cups and measuring spoons (for measuring soap, water, salt, etc.)
Students should have adult supervision. This activity can be done individually, in groups or as a class. If you choose to complete it in groups or as a class, students could take turns looking at the strawberry DNA with a magnifying glass after the session to see it more closely.
Note that if you do not have access to these items, our volunteers will be completing the activity on camera. They will ask students to type what they expect will happen so that students can still participate.
Please join us for our weekly STEM Storytime series on Tuesdays at 1 p.m. ET in English! If you cannot make it to a live session, feel free to register and you will be sent a link to the recording afterwards.
