Density Experiment Worksheet

Name:

Date:

Science experiment with objects floating and sinking

🔬 Part 1: Planning Your Experiment

1. WALT: We Are Learning To conduct experiments testing the density of various liquids and solids.

2. Vocabulary Check: Circle the words you know:

Mass - how heavy something is

Volume - how much space something takes up

Density - how much matter is packed into a space

Float - stays on top of liquid

Sink - goes to the bottom

3. My Hypothesis (Prediction): Complete the sentences:

I think the _________________ will float because _________________________________

I think the _________________ will sink because __________________________________

4. Materials I will test: Tick the items you will use:

Wooden cube

Metal washer

Plastic bead

Cork

Small stone

Other: _______________

5. Liquids I will test in:

Water

Oil

Syrup

Soapy water

📊 Part 2: Recording My Results

6. Experiment Results Chart: Draw or write what happened:

Object: _____________ Liquid: _____________ Result: Floated / Sank (circle one)

Drawing:

Object: _____________ Liquid: _____________ Result: Floated / Sank (circle one)

Drawing:

Object: _____________ Liquid: _____________ Result: Floated / Sank (circle one)

Drawing:

7. My Observations: What did I notice?

8. Was my hypothesis correct? Complete the sentence:

My prediction was _____________ because _________________________________

🎯 Part 3: Conclusions and Extensions

9. What I learned about density:

Dense objects _____________ and less dense objects _____________

10. Real-life connections: Where do we see floating and sinking?

11. Extension Challenge: How might temperature affect density?

I think hot liquids are _____________ dense than cold liquids because:

12. Next experiment idea: What would I like to test next?

Success Criteria - Tick when complete:

I made a prediction about what would float or sink

I tested different materials in liquids

I recorded my results with drawings or words

I used scientific vocabulary correctly

I explained my findings clearly
