Lesson cards Each skill starts with a teaching card, then moves into a focused question block. These cards keep the topic learnable before the quiz pressure arrives.
End-topic quizPaper 1
Exothermic and endothermic Simple explanation
Exothermic reactions transfer energy to the surroundings.
Analogy or example
A hand warmer uses an exothermic reaction to release heat.
Misconception trap
Endothermic reactions are always slow.
Real-world relevance
Exothermic and endothermic links classroom reactions to materials, energy, resources and everyday products.
Vocabulary check
exothermic, endothermic, reactions, transfer, energy
Simple explanation
Breaking bonds requires energy.
Analogy or example
A reaction is exothermic if more energy is released making bonds than is taken in breaking bonds.
Misconception trap
Making bonds takes in energy.
Real-world relevance
Bond energies links classroom reactions to materials, energy, resources and everyday products.
Vocabulary check
bond, energies, breaking, bonds, requires
Simple explanation
Reaction profiles sits inside Energy Changes, so learn the core definition and the exam example that usually comes with it.
Analogy or example
For a longer answer, start with particles or bonding, then connect that to the observation or calculation.
Misconception trap
Reaction profiles can be confused with nearby Energy Changes ideas.
Real-world relevance
Reaction profiles links classroom reactions to materials, energy, resources and everyday products.
Vocabulary check
reaction, profiles, sits, inside, energy
