Question

a blocks physics teacher has assigned everyone in his class the task of conducting an experiment. to write up their experiments, they must use the rubric provided below. match each summary of the steps in brocks experiment to the appropriate category in the experiment outline. step 1. formulate a question about a phenomenon brock asked, does size affect the buoyancy of an object in water? step 2. collect data brock placed wooden cubes that were 1 cc, 10 cc, and 100 cc in water. he observed their buoyancy. then he placed iron cubes of 1 cc, 10 cc and 100 cc in water and observed their buoyancy. step 3. form a hypothesis brock thought, for an object made of a given material, increasing the size of the object wont affect its buoyancy in water. step 4. test the hypothesis through an experiment brock noted that ice floats in water, whether it is a small ice - cube or a huge ice - berg. step 5. draw a conclusion brock said, since all wooden cubes float and all iron cubes sink, size does not affect the buoyancy of an object in water.

Explanation:

The task is to match steps of an experiment to the scientific - method categories. Step 1 is formulating a question about buoyancy, which is the start of the scientific process. Step 2 involves collecting data on the buoyancy of different - sized wooden cubes. Step 3 is forming a hypothesis about how size affects buoyancy. Step 4 is testing the hypothesis through an experiment, and Step 5 is drawing a conclusion based on the experiment results.

Answer:

Step 1: Formulate a question about a phenomenon - Brock asked, "Does size affect the buoyancy of an object in water?"
Step 2: Collect data - Brock placed wooden cubes that were 1 cc, 10 cc, and 100 cc in water. He observed their buoyancy. Then he placed iron cubes of 1 cc, 10 cc and 100 cc in water and observed their buoyancy.
Step 3: Form a hypothesis - Brock thought, "For an object made of a given material, increasing the size of the object won't affect its buoyancy in water."
Step 4: Test the hypothesis through an experiment - (No new action described here that is distinct from data - collection; perhaps should be more about actively manipulating variables to test).
Step 5: Draw a conclusion - Brock said, "Since all wooden cubes float and all iron cubes sink, size does not affect the buoyancy of an object in water."
