## Simulating Gravity on Film

Simulating Gravity on Film Zero-G refers to weightlessness and means “zero g-force” not “zero gravity” as some would believe. It’s most commonly envisioned as astronauts floating around in space. You can experience zero gravity in a free falling airplane too and in fact, astronauts use these free falling planes to train in a weightless environment. 300 miles above the earth, where the space shuttle flies, gravity is only about 15% less than it is at the surface of the Earth – not much of a difference. You can think of weightlessness either as the absence of gravity (which is basically wrong) or as gravitational force pulling on an object from all sides equally (which is basically right). In this experiment, we’ll change the direction that…

## I’m feeling pretty heavy with all this metal in me

I’m feeling pretty heavy with all this metal in me If you sit there and ponder the foods that you eat for a bit, you’ll realize that you eat plants and animals just like other fuzzy creatures in the forest. But did it ever occur to you that you eat metal too? Just like a tool grinder chews through a metal blade, little scientists chew through metal in their food without even really thinking about it. Even more eye opening is the fact that metal in your diet is required to survive. Iron is a part of everyone’s healthy diet and yes, it’s the exact same iron that’s used to make metal nails. Oxygen is transported through your body in your blood and iron is…

## Galileo’s Free Fall

Galileo's Free Fall You may already know that there is a mystical force called gravity that pulls everything on Earth downward. This is really cool since if we didn't have gravity we'd all be floating around in space. Do you think that this mysterious force pulls heavy objects faster than a light object? Reeko thinks the answer may surprise you. Place newspapers on the floor around the chair. Stand on the chair while your partner lays on the floor peering at the newspaper. Hold the 2 oranges in each hand. Extend your arms straight out away from your body (and over the newspapers) so that each orange is the same height from the floor. Let go of both oranges at the same time. Did they…

## Diet Coke and Mentos Eruption

Diet Coke and Mentos Eruption Reeko will never forget the first time he discovered this unique experiment. He learned three very important things that he has never forgotten to this day. Firstly, if you mix Mentos and Diet Coke, you get a violent eruption that will spew a gallon of sticky cola on you before you can even blink an eye. As he passed through the lab animal house, on his way to the kitchen to clean up, he learned something else – rats love coke! Before he knew it, he had 50 of those little furry critters clinging to his lab coat, licking away at the sticky mixture that had drenched his jacket (and they jumped him from behind knowing that he wouldn’t be…

## The evolution of a spider (or not) – science and religion battle over Darwin’s Theory of Evolution

What is the Theory of Evolution? Being a prominent (ahem) member of the scientific community, Reeko has a lot of scientist friends.  Reeko knows that the thing that bugs scientists more than anything, is when people don’t believe their theories (well, that and burning lab coats). And when it comes to Darwin's Theory of Evolution, scientists treat it almost like a religion. On the flip side, some religions have a big problem with the scientists’ Theory of Evolution making the whole subject of “natural selection” a huge heated debate between scientists and religious groups. Scientists theorize that humans evolved from single cells to fish to monkeys. Some religious groups, called creationists, take offense at this proposal saying it’s silly to think that people magically grew, over…

## Splatter blood for blood spatter analysis

Splatter blood for blood spatter analysis First we will let you in on a little secret. When you or your brother or sister do something wrong, your parents have to figure out who did it. To parents this is like a whodunit game and in fact, they have a secret name for it that they have sworn never to reveal to the kids (breaking this rule can result in loss of their official parenting card). It’s called the “which kid do we smack this time” game. And no, they don’t roll dice or draw straws to figure it out the winner. Parents have an eerie, almost superhero-like ability that allows them to scan human faces to determine the guilty party. It worked so well that a…

## Things aren’t always as they appear – light refraction experiment

Experiment to demonstrate the principle of refraction Ever reached down into the bath tub water to grab a toy and found that it was not in the position it appeared to be in? What you are experiencing is the effect called refraction. When light enters the water (or any transparent material) it slows down slightly. If the light enters the water at an angle then this change in speed causes the light beam to bend away from its original path. This is called refraction. Let's conduct an experiment that allows us to see the effect of refraction. Fill the glass 2/3 full of water. Place the pencil in the glass holding it straight up and down ( not at an angle). Notice that the pencil…

## Fooling Around with your Mind

Using mirrors to confuse your brain (and Dad) Our eyes see everything going on around us.  The eyes then send this information to our brain which then interprets the information they are given.  Sometimes the brain has to fudge a little when making these interpretations.  This is especially true when our eyes see something that the brain knows cannot be true.  In cases like this, the brain interprets the information the best it can and may end up feeling a little bit Have Dad leave the room.  Don't say we didn't warn you. Glue the two mirrors together, back to back.  Be very careful not to cut yourself on the mirrors.  If the edges of the mirrors are too sharp, you may want to apply…
