Challenge Problems

Push your limits with challenges.

Question 1

You are tasked with investigating how temperature affects the solubility of salt in water. Outline the experimental design including your variables, procedure, and safety considerations.

💡 Hint: Consider how you plan to measure solubility accurately.

Question 2

In a classroom experiment, you find that reaction times vary when students perform tests at the same temperature but different times of day. Discuss how you would control for time of day in your experimental design.

💡 Hint: Think about how student energy levels may fluctuate throughout the day.
