1. States of Matter and Changes – Melting, condensation, dissolving salt in water, reversible vs. irreversible changes, and effects of temperature on solubility. 2. Micro-organisms and Their Role – Identifying yeast as a fungus, usefulness of micro-organisms in food production and decomposition, and their role in disease. 3. Electricity and Circuits – Understanding conductors and insulators, effects of broken bulbs in circuits, series vs. parallel circuits, and ways to increase bulb brightness. 4. Forces and Motion – Identifying forces such as air resistance, friction, upthrust, and weight, and investigating spinner drop times with varying weights. 5. Ecosystems and Adaptations – Food chains, predator-prey relationships, plant growth and fertilization, woodlice habitat preferences, and snowshoe hare adaptations.
