Chromosomes, DNA, and Genes-Roadmap To Understanding The Foundation Of Genetics | Interactive Science
| Some things you just have to understand before you can move on. In math, addition and subtraction come before multiplication. And with genetics, you’ve got to understand chromosomes, DNA, and genes before anything else can make sense. DNA is something they’ve heard of hundreds of times. Now it’s time to show them what it is.
If you use this lesson in combination with another one of ours called “DNA Chain” you’ll have a solid foundation on which you can build upon. And not only will students lose their fear of the words “chromosome” or “DNA”, but they’ll know exactly what you’re talking about!

Interactive Science Lessons With A Math Emphasis
With all the emphasis being placed on students being able to learn and perform mathematics, it's becoming increasingly difficult to get and hold students' attention when we try to teach. They do math in every classroom now, and with that kind of competition you'd at least like to make your presentation interesting. You'll find a strong emphasis on math when you do these lessons:
The nice thing about the math in these lessons is there's a point to it, so it's not just rote and repetitive. In fact the numbers can get downright crazy, but the mystery unfolding in the lesson will keep most of your students from putting up those "fear walls" that can shut down all thinking. And in many of our other lessons we've tried to sneak in as much math as we could. Suddenly, implementing math isn't so bad, is it?
