DNA Chain- The Fear-Buster | Interactive Science
| Fear can cripple a mind quicker than anything. But how can you go from fear to peace and understanding in just 45 minutes? Easy- have students make a cuddly 40-foot long section of DNA with their own hands. Then, with all fear gone and their curiosity piqued, you can step in and teach the fundamentals by simply pointing, talking, and applying everything to this grand model.
This activity is a perfect compliment to another one of ours called “Chromosomes, DNA, and Genes”. If used together, you’ll have a foundation for anything you want to do with genetics.

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?
