In science class with 3rd and 4th grade, we did two experiments on mass and volume.
We tested a flat vs inflated balloon to see if air had mass.
Later we tested a square box vs a rectangular box to see which one could contain more rice
In science class with 3rd grade, we learned about attraction and repulsion between magnets. 🧲 We made some magnets float!
Then we tested different kinds of materials: carton, wood, plastic, cloth, steel, silver, and aluminium. There were three kinds of metals, but we learned that magnets don't work with all metals!
THANKS BERNICE! CONGRATS!!
