Science in Year 5

Today, Year 5 have been thinking about the force of friction.

We used jelly cubes, containers, chopsticks and sunflower oil.

We transferred the  jelly cubes from one bowl to another with chopsticks.

Then, we added a little sunflower oil to the jelly cubes and moved more of them to another bowl.

As scientists, we did the comparison more than once and noticed any differences.

What do you think happened? Why?
