Core Skills Analysis
Science
- BJ investigated how heating changes a food item, noticing that marshmallows changed in colour, smell, texture, and structure as the time over the flame increased.
- BJ observed a chemical change in action through browning and charring, showing that the Maillard Reaction creates new flavours and colours when heat causes sugars and proteins to react.
- BJ compared multiple stages of heating, which helped him see that the outside and inside of the marshmallow changed at different rates and that some changes were irreversible.
- BJ strengthened his scientific inquiry skills by making careful observations, recording results, and linking what he saw to the effect of heat on materials.
Mathematics
- BJ used time intervals from 20 seconds to 1 minute 20 seconds, showing an understanding of measuring and comparing duration.
- BJ made comparisons across different heating stages, which involved ordering results and noticing patterns as time increased.
- BJ estimated and applied distance by holding the marshmallow about 8 cm from the flame, connecting measurement to real-world investigation.
- BJ’s activity supported data collection and comparison skills, as he matched observations to each timed stage of the experiment.
English / Language Arts
- BJ recorded observations in detail, using descriptive language about appearance, smell, texture, and inside structure.
- BJ practiced sequencing by describing what happened at each stage of heating, from early browning to heavy charring.
- BJ’s investigation encouraged precise vocabulary, such as burned, charred, gooey, and melted, to communicate scientific changes clearly.
- BJ demonstrated the ability to explain cause and effect in writing, describing how heating led to different changes in the marshmallow.
Tips
To extend BJ’s learning, try turning the investigation into a simple data table or graph that shows how the marshmallow changed over time, helping him connect scientific observations with pattern-seeking and measurement. He could also compare the results of heating from different distances, such as closer or farther than 8 cm, to see how distance affects browning and burning. A follow-up discussion about which changes were reversible and irreversible would deepen his understanding of physical and chemical change. Finally, BJ could write a short explanation or draw a labelled diagram showing the outside and inside of the marshmallow at each stage, reinforcing careful observation and scientific communication.
