Fact checking GMOs


This is not an article about the pros and cons of genetically modified organisms. I am not arguing for them or against them. Instead, the goal of this article is to help you learn some of the basic science involved, to make it easier for you to fact check articles on this topic.

Big Numbers

This time we will take a look at some big numbers. In the study of science, you will run into all sorts of very large numbers, and it can get to be overwhelming.

Arm Raising

This experiment is something that we used do for fun when I was a kid. (No jokes about dinosaurs or the Dark Ages, please.) It was back in the days before video games and the internet. Back in the days when there were only 4 TV channels and you had to get up and turn the dial on the TV to change the channel. Even so, we still had lots of fun. This is a science trick that always amazes people.

AM/FM Radio Waves

This week's experiment comes from a question that I received about which is better, AM or FM radio. As we shall see, the answer depends on what properties you are basing your answer on. As we will see, each has advantages and disadvantages.
