1. Adaptations and Survival: Arctic fox predator traits (sharp teeth, camouflage) and cold-weather adaptations (thick fur, compact body shape); features help it hunt and stay warm. 2. States of Matter: Particle models for solid (copper = tightly packed), liquid (water = loosely connected), and gas (helium = widely spaced, fast moving). 3. Forces and Motion: Sailing boat forces include gravity, upthrust, air resistance, thrust, water resistance; understanding balanced and unbalanced forces. 4. Experiments and Variables: Seed germination affected by temperature; solubility tests with stirring and repetition; identifying dependent variables and fair testing methods. 5. Magnetism and Materials: Identifying magnets using attraction/repulsion; plastic as non-magnetic; difference between magnets (produce force) and magnetic materials (respond to magnets). 6. Earth, Body, and Environment: Earth orbits Sun in 365 days, Moon is a natural satellite; digestive organs in sequence (mouth to anus); pollution examples (CO, SO₂); air layer = atmosphere.
