In class we decided that the rate of a reaction increases when there are more collisions or when the activation energy is reduced. We then determined that there were four ways to increase the reaction rate: increase temperature‚ add a catalyst‚ increase surface area‚ and increase the concentration of reactants. The objective of this lab was to experimentally show how temperature and surface area impact the rate of reaction‚ so only two of these methods were tested. The evidence indicates that increasing

glued using white glue or wood glue. They can also be painted using any latex paint or water based paint. The boat that you see in the picture has a rudder we made a rudder to support the direction of the speed boat that we have made. We’ve used a Popsicle stick to have a rudder in our speed boat. But you may try different possible methods to construct a rudder in your boat. We also put some Styrofoam cup at the back of our boat with the propeller that we have so that the wind will have more force

In addition‚ as in 3D wireframe images‚ the figure can appear to rotate in either direction‚ depending on how your brain interprets it. It can also spontaneously reverse the direction of rotation. (In a real 3D wireframe image the image can also appear to rotate around a different axis.) The rotation of Lissajous Figures is something you need to see‚ so I am posting a program to do this. Because the sine function is computationally intensive‚ the program starts out by calculating a table

I learn to play an instrument?” Whether or not it is the guitar‚ drums‚ piano‚ or flute a child could possibly have the thought of wanting to learn how to play an instrument. When Mom and Dad end up saying no to their child they should stop and realize that when a child knows how to play a musical instrument it can help them out in many more ways than they know (iDiva). Having a young kid learn an instrument can help develop better coordination‚ build better concentration‚ help with stress relief

Reading Journal – Paul Bowles’ and “A Distant Episode” Setting is crucial in this story. Even though Bowles doesn’t explicitly say which country the professor is in‚ we can assume he is in the Middle East by his mention of traveling to the “warm country” (403). We can also safely assume that the professor is a linguist that specializes in Arabic. I was struck by the satire of this story. The Professor‚ a specialist in languages has his tongue pulled out so he will never speak again. “The man swiftly
