The fabulous Vertex volunteers were back again to lead our students in an exciting science experiment - extracting DNA from strawberries! During the strawberry DNA experiment students were able to extract, isolate, and observe the DNA of a strawberry using household products and materials. Students started off by reading over the instructions and gathering materials for the experiment. Every student had their own scientist kit equipped with gloves and safety goggles!
Students poured an extraction mixture into a bag with strawberries. They used their hands to mash and smoosh the strawberries inside the bag so that no large pieces were remaining.
Students then poured their strawberry pulp and extraction mixture through a strainer. They isolated the DNA on the surface of their mixture and pulled out the DNA! Many students thought the DNA looked like snot or slime.
Students learned that DNA is present in all plants and animals and determines all genetic traits. We had a great time thinking like scientists and showing persistence.
