The members in our group were Whitney‚ myself‚ and Charlotte. The title of this lab was “reaction types.” The purpose of this lab was to identify the reaction type‚ balance equations‚ and observe the reactions .Our hypothesis was if there was many stations with fire‚ then they’re would be many combustion reactions. The procedure of the first lab was to place a solid piece of magnesium metal in the bottom of the smallest tube. Place this test tube in the test tube holder. Using tongs pick up the

Animal Intelligence Animals are smarter than people think they are. As animal studies keep on increasing‚ we find out that some animals are close to our level of thinking. Animals such as chimps‚ parrots‚ elephants‚ dolphins and monkeys have been studied and proved to us that they too have a good level of intelligence. Self recognition‚ social skills‚ language skills and the use of tools are all signs that scientist use to prove that these animals have a good capacity of smarts in their brain

Purpose The reason for this experiment is to prove that objects of different masses‚ when dropped from the same height‚ fall at the same velocity. Apparatus - 2 Marbles of different mass‚ one steel and one nylon - Dropping Mechanism with a lever to hold the marble and pull for drop - Bee Spi (measures velocity in kilometers per hour.) - Box to catch the marble on the way down Procedure The dropping mechanism was set up‚ with the BeeSpi attached to it at 26.5” from the lever that drops
