The document describes 9 experiments involving different materials and observations of their behavior. For each experiment, observations are recorded in a table and particle diagrams are drawn to represent interactions at the molecular level, such as iodine crystals dissolving in water or copper sulfate dissolving faster in hot water than cold water due to increased particle motion.
Using The Particle Model
- 1. Using the particle model – 1 Write your observations in the table. Draw particle pictures to show what is happening inside the materials. Experiment Observations Particle pictures 1 Iodine crystal in water 2 Dust from a board rubber 3 Syringes with sand and air 4 Cooked meat
- 2. Using the particle model – 2 Experiment Observations Particle pictures 5 Black ink in water 6 Ball and ring 7 Melting ice cube 8 Copper sulphate dissolving in hot and cold water 9 Floating and sinking
