1.) particles move faster in hotter temperatures than they do in colder temperatures 
2.) Increasing the temperature increases the reaction rate
3.) Because the particles in hot water move faster and causes a faster reaction time than colder temperatures ]]> 2017-05-01 13:13:16 UTC https://padlet.com/sciencegray/g4af6iepeac9/wish/169157076 https://padlet.com/sciencegray/g4af6iepeac9/wish/169157136 Station F

1. In a hot substance, particles move faster 
2. It goes faster if you increase the temperature of the reactants
3. The hotter the substance, the faster the particles move

1. 60 times stronger
2. The less malarkey it had the reaction was slower. In 1M it fizzed constantly for 2+ minutes, but in 6M the magnesium ribbon it disappeared. The higher concentration it has, the faster the reaction]]> 2017-05-01 13:14:09 UTC https://padlet.com/sciencegray/g4af6iepeac9/wish/169157284 https://padlet.com/sciencegray/g4af6iepeac9/wish/169157963 Station B - Particle Size Effects

1) Added chunk and powder to test tubes with hydrogen monochloride. The chunk test tube had small bubbles after a few minutes. The powder test tube fizzed immediately 
2) Concluded that the smaller the particles, the faster the reaction]]> 2017-05-01 13:17:08 UTC https://padlet.com/sciencegray/g4af6iepeac9/wish/169157963 https://padlet.com/sciencegray/g4af6iepeac9/wish/169158768 Station E
1) The apples w/ lemon keep their color.
2 and 3) Slows down oxidization process

1. The one reacted with KI
2.the state of matter that it is in
We mixed hydrogen proxide with yeast and that bubbled a lot. Then we mixed hydrogen proxide with potassium iodide and it changed colors and bubbled a little ]]> 2017-05-01 13:28:42 UTC https://padlet.com/sciencegray/g4af6iepeac9/wish/169161130 https://padlet.com/sciencegray/g4af6iepeac9/wish/169161996 After]]> 2017-05-01 13:31:30 UTC https://padlet.com/sciencegray/g4af6iepeac9/wish/169161996 reiddasher https://padlet.com/sciencegray/g4af6iepeac9/wish/169197236 Not Reid Dasher]]> 2017-05-01 15:19:58 UTC https://padlet.com/sciencegray/g4af6iepeac9/wish/169197236 sciencegray https://padlet.com/sciencegray/g4af6iepeac9/wish/169235723 The goal of today's collaborative lab is to work together to learn about reaction rates. Ultimately, the goal is to answer the question, "How can we speed up or slow down chemical reactions?"

Follow the instructions at your station and then post a summary to the Padlet. Your summary should include the following.

1) The title for your station

2) A concise description of your procedure

3) Thorough data and analysis

4) Video/photos to support your findings (Hint: when uploading media, take the photo/video using the camera, then import it from the camera roll. It kept crashing on me when I tried recording a video directly into the padlet post.)
