What is DNA?
deoxyribonucleic acid, a self-replicating material present in nearly all living organisms as the main constituent of chromosomes. It is the carrier of genetic information. You can learn more about DNA here.

Why is this Cool?
DNA is a part of every cell. What you’ve done is break apart the cell structure through a couple of chemical reactions using household ingredients. First the strawberry cell wall is broken with the salt, water, and liquid detergent mixture. Then you’ve caused the DNA to separate when the rubbing alcohol touched your mixture.

And here are some other cool STEM influenced DIY’s that you can try at home. In case you haven’t heard of STEM, Science, Technology, Engineering and Mathematics (STEM, previously SMET) is an education grouping used worldwide. The acronym refers to the academic disciplines of science, technology, engineering and mathematics. The term is typically used when addressing education policy and curriculum choices in schools to improve competitiveness in science and technology development. It has implications for workforce development, national security concerns and immigration policy. The acronym arose in common use shortly after an interagency meeting on science education held at the US National Science Foundation.

At Pop Shop America, we greatly prefer STEAM because the arts should always be included in education. According to DoSomething.org, researchers find that sustained learning in music and theater correlates strongly with higher achievement in both math and reading. And new brain research shows that not only does music improve skills in math and reading, but it promotes creativity, social development, personality adjustment, and self-worth.
