🔬 Part 1: Scientific Knowledge

1. What is crystallisation?

When liquids turn into gas

When dissolved substances form solid crystals

When solids melt into liquids

When crystals dissolve in water

2. In our experiment, what is the solute?

Hot water

Pipe cleaner

Borax powder

The jar

3. Which factors affect crystal formation? (Tick all that apply)

Temperature

Concentration of solution

Time

Colour of the pipe cleaner

4. Fill in the blanks using these words: saturated, solvent, precipitation

Hot water acts as the _____________ in our experiment. When the solution becomes _____________, crystals begin to form through a process called _____________.

📝 Part 2: Experiment Planning and Prediction

5. Before starting the experiment, predict what will happen to your pipe cleaner shape over the next 24 hours:

6. Why do you think crystals will form on the pipe cleaner rather than just floating in the water?

7. What safety precautions should you follow when working with hot water in this experiment?

8. Draw and label your experimental setup below:

📊 Part 3: Observations and Analysis

9. Record your observations at different time intervals:

After 30 minutes: ________________________________

After 2 hours: ___________________________________

After 24 hours: __________________________________

10. How do your actual results compare to your prediction from question 5?

11. Explain the crystallisation process using scientific vocabulary (include words like: solution, saturation, molecules, crystal structure):

12. Give two real-world examples where crystallisation occurs naturally or is used in industry:

Example 1: ________________________________________

Example 2: ________________________________________
