Preparing the Buoy

tan_ying_yin1 — 2024-01-31 22:42:27 UTC

1. Prepare the buoy by attaching a small ball of plasticine to the end of a drinking straw. Press the underside of the ball on the table to make it flat.

2. Take one or a few short video clips/photos of you/your group releasing the buoy into the measuring cylinder containing water. The video clips need not illustrate perfect execution of the experimental steps. 😊

Task 1: Finding the correlation between the height of the buoy and its weight

tan_ying_yin1 — 2024-01-31 22:42:27 UTC

1. Record the height of the buoy as its weight increases.

2. Post photo of each stage/step you have carried out.

3. State the conclusion: When the weight of the buoy increases, the height of the base of the buoy_________

4. Other than recording your observations on the worksheet provided, is there other way/form for us to record our observations/data?

5. Key in your results into the common excel spreadsheet for class discussion later. Click on the tab "weight".

* Do Task 2 before task 1: Finding the correlation between the height of the buoy and the surface of the water

tan_ying_yin1 — 2024-01-31 22:42:27 UTC

1. Record the height of the buoy as more water is added to the measuring cylinder.

2. Post photo of each stage/step you have carried out.

3. State the conclusion: When the surface of the water rises, the height of the base of the buoy_____________

4. key in your results into the common excel spreadsheet for class discussion later. Click on the tab "surface".

Task 3: Finding the correlation between the height of the buoy and the concentration of salt in the water

tan_ying_yin1 — 2024-01-31 22:42:27 UTC

1. Record the height of the buoy as the salt concentration increases.

2. Post photo of each stage/step you have carried out.

3. State the conclusion: When the concentration of the salt increases, the height of the base of the buoy______________

4.Key in your results into the common excel spreadsheet for class discussion later. Click on the tab "concentration".

Task 4: Determining the concentration of the salt in the unknown solution

tan_ying_yin1 — 2024-01-31 22:42:27 UTC

(a) Briefly describe the method you would use to determine the concentration of the salt in an unknown solution.

(b) Estimate the concentration of the solution.
(c) Post photo of each step/stage you have carried out.

I like the science experiments as me and my group mates work together as a team. We faced many challenges. I feel that Science is fun.
