sports science exploratorium research: i looked at the science of skateboarding and it intrigued me. when skateboarders do one of the most basic moves, the ollie, there are 3 forces involved in performing it. there are forces of the weight of the rider, a force of gravity on the board itself and a force of the ground pushing up on the skateboard. when someone does a successful ollie jump it looks like their feet are always touching the board but they aren't. his rear foot has to lift the same time the tail of the board is rising in the air to look like his feet are stuck on the board throughout the trick. this pertains to science because of the forces pulling and pushing on the board and rider, also the laws of gravity factor into skateboarding as well.

How hard a softball hits a surface and also how when a girl throws a softball and it slowly rises. I think it is so cool that a girls pitch can break gravity and slowly increase in the hieght. But i think they should have tested a girl trying to hit a baseball, because who knows, she may not be able to hit a baseball. That can be used for a new experiment.

I think if they were going to do it that way the should have also had a softball player hit both balls also. The baseball player is trained to hit baseballs so to me it isnt accurate data. But it is still amazing to see how the softball is harder to hit than a baseball and it packs more pound pressure than a baseball. I think the technique used to throw the balls influence how fast, powerfully and accurately they move. It is definately not the results I were expecting.

Partly because some people think women's sports are jokes, and that they are really easy. But I think what might cause the softball to be harder to hit than the baseball is the technique she uses to throw the ball. If you notice how they both throw the ball the baseball player turns his body while throwing once, he throws the ball his legs is off the ground which could mean his body is exerting more energy, that could take more energy to support his body subtracting the force that is used to throw the baseball. Now if you watch Jenny, she makes a giant leap and her body slightly turns and her arm is not as high as the baseball pitcher, but the ball leaves her hand before her body is off the ground it could mean that her body uses the right amount to throw the ball and the rest of the energy is used to lift her off the ground. The experiment is very nice but I would have added a girl softball player to hit both balls.

The dependent variable is the force used to hit the ball. My hypothesis for this exoeriment would read if a baseball was pitchde instead of a softball, then the force excerted to hit the baseball would be less than that of a softball. Two constants would be the brand of baseballs and softballs, as there are many different brands and also the pitcher who is pitching must stay constant. One possible source of error is the force of the pitch. It is proven that the force of the pitches ultimately will be different as you cannot perfectly repeat the same action twice. Also because after more than one pitch, the force will most likely decrease. Another source of error is the different types of pitch. When pitching a softball, you pitch underhand and are closer to the plate as when pitching a baseball you throw overhand, usually, and are farther away from the plate, which can ultimately vary the results. One thing that i find very interesting is that how strong you is not the only thing that will determine whether or not you hit home-runs. Another important thing is bat speed. The speed at which you swing your bat and the wind also contribute to the cause

DV: hit ratio (difficulty to hit the ball)
Hypothesis: If the ball type is a softball, then the hit ratio will be lower.
Constants: 1) force/direction of wind 2) (should have been) pitcher/force of pitch
Error: 1) Each ball was thrown at a different velocity 2) There were two different pitchers and pitching styles
Title: The Effect of Ball Type on Hitting Ratio

While browsing the Sports Science Exploratorium I found an article on the science of good hair. It was actually very interesting and really did pertain to science. The author of the article, Pat Murphy, discussed many of the bad hair problems many women- and even men- face. She used her own hair troubles as jumping off points to research and experiment what gives us good, or bad, hair! For example, the acidity of shampoo, and the detergent in it, is what makes hair beautiful and shiny. Alkali solutions and plain soap make hair dull, rough and unhealthy. A good alternative for no shampoo... lemon juice or vinegar! And to be honest, just because a shampoo foams really well, doesn't mean it works any better. The foaming agent is only added because many Americans associate foaming with more cleaning power! If you have lank, stiff hair and want some body, don't use conditioner! It weighs down the hair! Of course, conditioner is important very once in a while because it helps "heal" hair (hair is only dead cells, so it can't actually heal) by coating it, a if it were replacing parts of the hair's cuticle. There really is a lot of biology and chemistry involved in having good hair! Who knew?!
