We discovered the importance of accurate measurement...
We talked about absorption and how we could change how quickly water was absorbed by sugar cubes. We timed how long it took for a cube to dissolve completely and then estimated how long it would take for different size piles of sugar cubes to dissolve. Then we designed our own experiments to test our own hypothesis, and answer our own questions.
We made water cycle bracelets to remind us of the key changes that happen. We used a yellow bead for the sun's heat, a clear bead for evaporation, a white bead for condensation and clouds, a blue bead for precipitation, rain, snow or hail, and a green bead for run off- when the water runs back into the rivers, lochs, sea and ocean.
Hypothesis - what I think will happen.
Equipment - what I need.
Method - what I did.
Results - what happened.
Analysis - what I found out.
Evaluation - what I learned.
We learned how to write up an experiment.
It was great fun experimenting with different levels of water in glasses and making music!
As we observed, we questioned, estimated time, timed, discussed, wondered and listened,
amongst other things...
