Detailed Example

Surface Tension Demonstration (Science - 5th Grade)

Materials Needed

  • Cups of water (one per pair)
  • Pennies (10 per pair)
  • Paper towels
  • Eye droppers (optional)
  • Recording sheet

Preparation

Gather all materials in advance. Test the experiment yourself. Prepare simple recording sheet with prediction and result spaces. Plan transition back to regular instruction.

Step-by-Step Instructions

1.

Announce: 'Two-minute lab! Clear your desks. Materials coming.'

2.

Distribute cups of water filled to the brim and pennies.

3.

Question: 'How many pennies can you add before the water overflows? Write your prediction.'

4.

Students carefully add pennies one at a time, counting.

5.

When water overflows, record the result. Most students drastically underestimate.

6.

Class data collection: What was your prediction? What was your result?

7.

Observe the water surface before overflow: What do you notice? (Bulging dome shape)

8.

Quick explanation: Surface tension - water molecules stick together like a skin.

9.

Connection to lesson: 'Today we're learning about molecular forces. This is one example.'

10.

Clean-up routine: 30 seconds, specific jobs assigned.

Differentiation Strategies

Pair fine motor challenges with steady-handed partners. Provide visual prediction scale. For advanced students, ask them to design a follow-up experiment testing surface tension.

Assessment Guidelines

Compare predictions to actual results. Listen to explanations for accuracy. Follow-up quiz questions assess conceptual understanding beyond just the activity.
