Fetch with Ruff Ruffman uses a laser to measure temperature?

I am sorry to point this out, but I can’t help it. My kids watch this show “Fetch with Ruff Ruffman”. It’s mostly an ok kids show. However, there was a problem. In one episode, some kids were in the desert and measuring temperature with (they said it several times and it was even a quiz question at the end) – a LASER. Here is the device they used:


This is an infrared thermometer with a LASER aiming system. The laser is only there to help you aim. The temperature is determined by measuring the infrared radiation from the object. You don’t even NEED the laser. Those ear thermometers work the same way, but they don’t have lasers.

I guess when a laser is involved, it just makes it so cool that it must be the most important thing. I am going to put a laser pointer on my computer – that way people can say “look, that computer runs on LASERS.”

Cat in the Hat sits on a throne of Lies!

My kids like books. Especially when they are going to bed. I let my daughter pick a book and she picked “Clam-I-am. All About the BEACH” by Trish Rabe. It is nice, it rhymes. The pictures are pretty. Then I get to this page:


So, the ocean is blue because of the sky? How do you get green oceans? How about brown (I live in Louisiana, trust me – the gulf of Mexico can be brown)? What about when you are underwater, everything looks blue. The best answer to why the ocean is blue is that that is what color does not get absorbed. All colors of light interact with the water. Reds are mostly absorbed, the blue gets scattered.

[Here is a better explanation from the Library of Congress](http://www.loc.gov/rr/scitech/mysteries/oceanblue.html).

Would it be so hard to have someone look over the science in a book? I would do it if they asked.
