Question

OMEWORK EXERCISE: DESIGNING AN INVESTIGATION USING SCIENTIFIC METHOD:

Observation: Mrs. Ntuli has two different kinds of pots in her kitchen. The food always seems to
cook quicker when she uses the aluminum pots than when she uses the enamel pots.
Write a scientific report with the following headings:
• Hypothesis
Aim
Apparatus

Answer 1

Aim: To investigate which material of pot will cook food quicker.

Hypothesis: The (aluminum/enamel) pots will cook the food quicker than the (aluminum/enamel) pots.

Apparatus:

- Aluminum pots

- Enamel pots

- Stove top

Variables:

Independent variable (What will be changed) - Material of pot

Dependent variable (What's being measured) - Time taken for food to cook

Controlled variables (What's staying the same) - Size of pot, type of food being cooked, quantity of food being cooked, stove top

Method:

1. Place aluminum pot on stove top and turn on stove top
2. Cook your chosen food in the pot
3. Record time taken for food to cook
4. Repeat steps 1-3 another 2 times
5. Place enamel pot on stove top and turn on stove top
6. Cook chosen food in the pot
7. Record time taken to cook
8. Repeat steps 5-7 another 2 times

Results: (I don't have results because i never conducted this experiment)

Conclusion: This experiment showed that (aluminum/enamel) pots cooked the food quicker than (aluminum/enamel pots). These results (supported/rejected) my hypothesis.

Evaluation: (Never did the experiment, so there's nothing to evaluate)

Step-by-step explanation:

I hope this helps :)
