We started by looking at the powders and guessing what each one was. Then we decided we needed some more evidence because we still weren't sure what they were. Finally we decided to taste them - Jennie said they were all edible.
Tasting gave us our final piece of evidence!
Substance A looked white, fine and grainy,didn't have much of a smell, tasted yuck and fizzed on our tongues.
Substance B looked like salt or sugar, didn't have much of a smell and tasted quite sour
Substance C looked like flour but tasted sweet.
What do you think out 3 substances were and what did we make when we mixed all 3 together?
