For an introduction to what discrepant events are and how I used them with my IGCSE students, click here.
The discrepant event resources for IGCSE are divided into two groups: Form 4 Discrepant Events and Form 5 Discrepant Events.
Form 4 Discrepant Events
- Magical Candle: About gaseous behavior.
- Plastic Bottle Canons: An observation and deduction exercise about elements in the periodic table.
- Water Bottle Explosion: About state of matter, energy and pressure.
- Uncanny Can: About state of matter.
- Dancing Coin: About state of matter.
- Rubbery Egg: About state of matter.
- Hare Brain Chemistry: An observation and deduction exercise on the patterns of reactivity.
- Fun with Liquid Nitrogen: About energy and state of matter.
Form 5 Discrepant Events
- Plastic bottle Canons: An observation and deduction exercise about elements in the periodic table and Stoichiometry (Quantitative Chemistry).
- Magical Beakers: About acid-base chemistry.
- Magical Crystals: About ion-exchange/precipitation/double displacement reaction.
- Gunpowder: Ideal Mixture: About Stoichiometry (Quantitative Chemistry)
- Sugar Daddy…with Flare: About Redox Reactions and Stoichiometry (Quantitative Chemistry)
- Cracking Crackers: About redox reactions.
Enjoy!
