Science Class

Keira had to find iron in her cereal. Smashing cereal with a meat tenderizer is fun!

 
The boys also had to do a fun experiment for their biology class: extracting DNA from split peas.

Setting things up: water, salt, lemon juice, rubbing alcohol, spelt peas and clear hand soap.
We mashed the split peas in a blender with water and salt, strained them so we would only have the split pea "soup."
Next we added rubbing alcohol and liquid hand soap, stirred and waited for a few moments.


The streaks you see you see are strings of DNA. The longer we waited the longer they got. We were able to twist them around a toothpick. A cool experiment with things you have at home.
