Lab Activity C2
Making Inferences from Observations

2. Analysis and Conclusions
Identify one property that is the same for all of the canisters. Also identify one property that is different for all of the canisters. Note: Color, shape, volume, and mass are examples of properties.
Same properties: shape, color, size, volume
Different properties: mass, density, weight

3. 2. For the objects inside the canisters, identify one property that can be inferred about each of them. Also identify two properties that cannot be known about any of them without opening the canister. Inferred properties: qualitative shape (round, flat), qualitative number (none, one, many), total mass of objects; Not-inferred: color, individual volume

4. The number of objects in each canister continues to vary, but the type of object used is the same.

5. 3. For each of the following, determine if the graph for the modified activity would be a straight line. Explain your answer.
The number of objects in each canister continues to vary, but the type of object used is different. (i.e. paperclips)

6. b. The number of objects in each canister continues to vary, but no two canisters contain the same kind of object.

7. c. Each canister holds the same number and type of object.

8. d. Each canister holds the same number of objects, but no two canisters hold the same type of object.

9. What are some other methods you could use to infer more properties of the objects in the canisters? Hint: Remember how you found the empty canister.
