Grade 8 Science
Forces that touch and forces that reach, the two effects one electric current has, what matter is made of and how elements, compounds and mixtures differ, what dissolves and what does not, how mirrors and lenses bend a beam, the cell under a microscope and the microbes that raise dough, the winds that pressure differences drive, and the food chains that tie an ecosystem together.

- Forces: contact and non-contactLesson
Sort forces by whether they need the objects to touch, read a spring balance, and keep weight and mass apart.
- Magnetic and heating effects of currentLesson
Explain how a current makes a magnet and how it makes heat, and say what changes the strength of an electromagnet.
Structure and Properties of Matter
- The particulate nature of matterLesson
Explain the three states of matter by how tightly their particles are held and how much space sits between them.
- Elements, compounds and mixturesLesson
Tell an element from a compound from a mixture, and say which of them can be taken apart by physical means.
- Solutes, solvents and solutionsLesson
Name the solute and the solvent in a solution, tell a saturated solution from an unsaturated one, and say how temperature changes what will dissolve.
