Water Absorption Science Project
🔬 Part 1: Understanding the Project
I can: Analyze a completed science fair project and identify its key components.
Project Title: "Which Material Absorbs Water Best?"
Question: Which material absorbs the most water: cotton, paper towel, or sponge?
Hypothesis: I think the sponge will absorb the most water because it has many tiny holes.
Materials: 3 cotton balls, 3 paper towels, 3 small sponges, measuring cup, water, scale, timer
Procedure:
1. Weigh each dry material and record
2. Soak each material in water for 30 seconds
3. Remove and weigh again
4. Calculate water absorbed (wet weight - dry weight)
5. Repeat 3 times for each material
📊 Part 2: Analyzing the Data
Results Table:
Cotton Ball: Trial 1: 2.1g, Trial 2: 2.3g, Trial 3: 2.0g → Average: 2.1g
Paper Towel: Trial 1: 4.2g, Trial 2: 4.0g, Trial 3: 4.1g → Average: 4.1g
Sponge: Trial 1: 6.8g, Trial 2: 7.0g, Trial 3: 6.9g → Average: 6.9g
