I learnt that their are objects with different mass.
First I compared a pen vs a cube. I predicted that the pen would have more mass then the cube. My prediction was correct the pen had more mass then the cube.
Next I compared a pen vs a green cylinder. I predicted that the cylinder would have more mass. My prediction was incorrect the pen had more mass.
Lastly I compared a pen with a leaf. I predicted that the pen was going to win. My prediction was correct the pen had more mass.
I enjoyed this activity because I learnt about mass. I need to improve predicting which mass would be heavier. I did well at picking lighter objects.
