FunBrain: Guess the Number?

Although this game looks like it should be just a random guessing game, it really takes concentration and attention to the incorrect numbers you’ve picked while trying to guess the correct one.  You have choices of choosing numbers between 1 and 10, 1 and 100, and -1000 and 1000.  As you guess, a chart shows whether your guess is too high or too low.  By knowing that, you can focus in on the correct number.  The catch is that you have only a certain number of guesses.  If you choose to play the hard way, you’ll find out if your guesses are too high or too low, but you’ll have to remember what numbers you’ve picked.  Apr. 4http://www.funbrain.com/guess/

Dragonfly TV:  Real Scientists Brian Sidwell and Mike Lowe

 Bicycle riding season is here.  If you don’t already wear a bicycle helmet, after watching this video, you will.  Scientists Brian Sidwell and Mike Lowe design bicycle helmets by experimenting with shape, materials, and durability.  If a helmet doesn’t fit correctly, you might not want to wear it, or it might not protect you well enough.  You want your helmet to last for as long as your head fits in it, so how it stands up to the elements is an important factor in its design.  Watch this video where the two scientists show how they design bicycle helmets, test them, and show how helmets protect the brain in a crash.Apr. 3http://pbskids.org/dragonflytv/scientists/scientist27.html
