Question

brocks physics teacher has assigned everyone in his class the task of conducting an experiment. to write up their experiments, everyone must use the outline 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 and observed their buoyancy. then he placed iron cubes of 1 cc, 10 cc, and 100 cc in water. he 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 said, since all wooden cubes float and all iron cubes sink, size does not affect the buoyancy of an object in water. step 5. draw a conclusion. brock noted that ice floats in water, whether it is a small ice - cube or a huge iceberg.

Explanation:

Step 1: Identify the scientific - method steps

The steps of a scientific experiment are: formulating a question, collecting data, forming a hypothesis, testing the hypothesis, and drawing a conclusion.

Step 2: Match steps to descriptions

• Step 1: Formulate a question - "Does size affect the buoyancy of an object in water?"
• Step 2: Collect data - Placing wooden and iron cubes of different sizes (1 cc, 10 cc, 100 cc) in water and observing buoyancy.
• Step 3: Form a hypothesis - "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 - Conducting the experiment with wooden and iron cubes.
• Step 5: Draw a conclusion - "Since all wooden cubes float and all iron cubes sink, size does not affect the buoyancy of an object in water."

Answer:

Step 1: Formulate a question - "Does size affect the buoyancy of an object in water?"
Step 2: Collect data - Placing wooden and iron cubes of different sizes (1 cc, 10 cc, 100 cc) in water and observing buoyancy.
Step 3: Form a hypothesis - "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 - Conducting the experiment with wooden and iron cubes.
Step 5: Draw a conclusion - "Since all wooden cubes float and all iron cubes sink, size does not affect the buoyancy of an object in water."
