8th Grade Science Inquiry by Kaiden ODuane https://padlet.com/k_oduane/un68niou1 Alka seltzer en-us 2019-02-06 19:14:02 UTC 2024-12-23 20:49:54 UTC hello@padlet.com https://padlet-assets.s3.amazonaws.com/icons/Pizza.png Forming a Question or Hypothesis k_oduane https://padlet.com/k_oduane/un68niou1/wish/328448725 Title: Plop plop, fizz fizz, oh what a science it is.

Question: If I put hotter water in the beaker will the alka-seltzer dissolve faster or slower?

Background: I know that the water temperature will change the rate of the dissolving alka seltzer. I also know that if the water gets colder it will dissolve slower than the hot water. The hotter the temperature gets the faster it dissolves because it will break down the matter a lot faster. The colder the water gets the slower it will dissolve because the chemical reaction makes it dissolve slower.

Hypothesis: I think that if I put the Alka-Seltzer in a beaker filled with hot water the Alka-seltzer will take less time to dissolve than the beaker filled with cold water because the how water breaks down the alka-seltzers matter a lot faster.]]> 2019-02-06 19:17:05 UTC https://padlet.com/k_oduane/un68niou1/wish/328448725 Designing the Investigation k_oduane https://padlet.com/k_oduane/un68niou1/wish/328455061 Materials: Alka-Seltzer, beaker, stop watch,  ice water, room temperature water, hot water a pencil and my notebook.

Procedures: 
  1. Fill the beaker with the hot water
  2. Put the Alka-Seltzer in the beaker
  3. Turn on the stop-watch
  4. Wait for the alka-seltzer to dissolve
  5. Write the time it took to dissolve the alka-seltzer in the booklet
  6. Do hot water steps two more times
  7. Repeat this process with the room temperature and ice water

Next I put the the alka-seltzer in the beaker timing the result. The higher the water temperature got the faster it dissolved the alka-seltzer. In my hypothesis I said that the hotter the water got the faster the alka-seltzer would dissolve. My statement was proven correct. There was only a few things that went wrong. The most frequent was that the stopwatch wouldn't always work. I have done this experiment many times and did not really learn anything new, however I witnessed that a sudden change of water temperature will completely shatter a beaker. I dont think there is anything this experiment applies to in the real world.]]> 2019-02-06 19:30:55 UTC https://padlet.com/k_oduane/un68niou1/wish/328456992 Collecting and Presenting Data k_oduane https://padlet.com/k_oduane/un68niou1/wish/349762847
                     HOT WATER                     ROOM WATER                            ICE WATER

Trial 1)        20.06                                  48.32                                            85.00          

Trial 2)        17.95                                  35.87                                            95.00

Trial 3)        15.55                                  50.87                                            65.00

Average)    17.18                                  45.02                                            81.66

Observation: I noticed that the hotter the water got ( this is my variable) the faster the Alka-Seltzer (my constant) dissolved. This is because the hotter the water got the Alka-Seltzers matter broke down a lot faster.
