Question

David noticed that when he ate chocolates they melted in his hands faster when his hands were slightly wet from sweat than his hands were dry. He was curious to see if other liquids would affect how fast they would melt? He decided to test out four different liquids, water, milk, lemon-lime soda, and orange juice. He then timed how long it took them to melt. He thought the chocolate would melt faster in orange juice that the other liquids because it is more acidic. The results are below.

QUESTIONS:
1) What was David's Question?

2) What was David Hypothesis?

3) What his independent Variable?

4) What his Dependent variable?

Answer 1

1. What liquid would melt the chocolate faster?

2. He thought that the orange juice would melt the chocolate faster.

3. The independent variable is the liquids.

4. The dependent variable is the chocolate.

Step-by-step explanation:

1. He was curious to see if other liquids would affect how fast they would melt? This is his question.

2. He thought the chocolate would melt faster in orange juice than the other liquids because it is more acidic.

He made a prediction or a hypothesis.

3. His independent and dependent variables are chocolate and liquid. Since he wants to know how fast the chocolate melts in different liquids, how fast the chocolate melts is dependent on the liquid that he uses.
