Interactive Science | Counting Atoms- An Investigation Into The Nanoworld Of Atoms

How in the world can you measure something that’s so small that it’s never been seen, and probably never will be? In this challenging but fun activity students will count the number of atoms in a metal cube not with their eyes, but with mathematics. When done, they will fully appreciate just how small atoms are.

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?

Always Illustrate

It’s our firm belief here that almost everything in science has a simple explanation, and the best ones include a demonstration with a reference to something students are already familiar with.

Have you ever sat and listened to a speaker who confused you? In your mind you might have thought, “Why don’t you show me what you’re talking about. Give me an illustration, please!” If they finally did give an illustration, then you remember your anxiety letting down. Remember to use word pictures often, because that’s how our minds learn best, and also because there’s usually a student in your classroom looking at you starving for an illustration but saying nothing.
