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

Effect of all-natural bath and body wash on millet seed growth. This experiment was conducted to determine what effect a household chemical would have on the growth of a plant. Everyday multitudes of chemicals are washed down the drains inside of our homes; many of these same chemicals are then being introduced into the environment through our water sources‚ such as rivers. This experiment will test the effect of all-natural bath and shower gel would have on the growth cycle of millet seeds. The

“polymer creatures‚” which are the things that are used in experiments about polymers. The polymer creatures‚ made out of two different polymers‚ are both hydrophobic and hydrophilic. This means that while the hydrophilic polymer absorbs water‚ the hydrophobic polymer keeps the shape that the creature was originally in while the water is inside the creature. Another name for this process is osmosis

How does the Amount of CO2 Affect the Rate of Photosynthesis? There are a number of variables that can affect the photosynthesis rate of Canadian water weed (Elodea). They are as follows:  The amount of light: an increased light level increases the rate of photosynthesis to a certain point where at another factor limits the photosynthesis rate.  The temperature: Increased temperature increases the rate of photosynthesis to a certain temperature‚ after which‚ essential enzymes
