Biology: DNA, the Code for Life



This week in Biology we covered A LOT of ground...Phonecian alphabet, pictograms, merits of letter-based writing systems, DNA as code, protein synthesis, and we still hand time for a quick round of Biology Hang-man.

After a quick review of the nuts and bolts of how DNA codes for proteins, the kids did a simulation activity in which they decoded 6 genes into the appropriate amino acid sequences and then drew the resulting organism.

Biology: DNA


























This week we started talking about DNA. The kids learned about its chemical structure, focusing on the 4 nucleotides and the rules for complementary base-pairing. Then we made models using clay.
