Broccoli Science

This time we will take a look at the science of cooking green vegetables. Now, some of you may be saying "Ick!", but even if you don't like to eat them, it is still interesting to watch them cook. Also, knowing some of the science may interest you enough to give them a second chance, and you may discover how delicious they are.

Breathing Hot and Cold

One of the most common questions that I get is where do I get the ideas for these experiments. Some are old classics that I try to give a new angle. Others are the result of questions sent to me by subscribers. Some of the ones that I like the best are the ones that just pop up, seemingly out of nowhere. This is one of those. It also comes with its own story, which makes it even better.

The story is one of Aesop's fables. If you have never read any of these, go read some. It is well worth the time.

Thoughts on a Science Fair Project, part 1

“Science Fair Project!”

Ahh, those three special words that can strike terror into the hearts of students, parents, and teachers. I have already begun to get emails requesting fun, quick, easy projects that no one has ever done before, and that will win the science fair. I wish I had a few hundred thousand projects that fit those requirements, but even that would not take the frustration out of this annual ordeal.

A Class Science Project

“I hear and I forget; I see and I remember; I do and I understand.”

Confucius, Chinese philosopher

Many of the things that students struggle with in the process of doing a science fair project are the result of not fully understanding unfamiliar tasks. If they have never written an abstract, or even read one, the challenge of composing one for their project can be truly daunting. The same is true for selecting a good topic for their project, properly stating their hypothesis, controlling variables, etc.
