lesson 3: student activity sheet background: 1. what do we know about water? we hear all the time that water is essential for life, but do we know why? what do we already know about water’s properties and how water supports life? as you and your classmates brainstorm, write the ideas in the t - chart below. properties of water why water is important for life how we could investigate this
Answer
Brief Explanations:
Water has properties like high - heat capacity, polarity, and cohesion. These properties make it important for life as it can regulate temperature, act as a universal solvent, and support transport in organisms. Investigations could include heating/cooling experiments for heat - capacity, solubility tests for solvent properties, and capillary action demonstrations for cohesion.
Answer:
| Properties of Water | Why Water is Important for Life | How We Could Investigate This |
|---|---|---|
| High - heat capacity | Regulates body and environmental temperature | Heat/cool water sample, measure temperature changes |
| Polarity (universal solvent) | Dissolves nutrients and waste for transport in organisms | Test solubility of different substances in water |
| Cohesion and adhesion | Facilitates water transport in plants (capillary action) | Observe water movement in narrow tubes or plant stems |
