Our next unit is Genetics and Heredity, which is pretty cool stuff! We will look at how traits are passed from generation to generation; how our DNA holds the keys to what makes us, well, us; and what our genes hold in store for us.
The first video deals with how our eye and hair color change. What gives me dark blonde hair and hazel eyes but my sister brown hair and blue eyes? The parts of our genes that code for these things are called alleles. Think of alleles as a pair of switches and depending on the combination of how you have those switches on and off, you will change the way someone or something looks.
The second video deals with how stress and external factors can change our DNA, and that of your kids! Thanks, Mom and Dad. No wonder I get so stressed about cleaning for company...kind of like this.
Let's get our learning on!
