LiquidsJalam saw that the honey ran off the spoon slowly.

Faye put one drop of honey onto a tilted tray.

Jalam measured how many seconds the honey took to run 10 cm down the tray.

They did this for seven different liquids.Here is their table of results.

(b) The table has one result missing.Use these results to predict how long it took the milk to run 10 cm.

(c) Look at the time taken for water and for custard to run 10 cm.

Jalam mixed equal amounts of water and custard.

He tested the mixture on the tilted tray.

Use their table of results to predict how long this mixture would take to run 10 cm.

(d) Jalam tested the honey on the tilted tray in the same way, but at different

temperatures.He drew a graph of his results:

Look at the graph.How long did it take honey at 40 °C to run 10 cm?

(e) Describe how the time it takes honey to run 10 cm depends on the temperature.

Helium Balloon(a) The children have some balloons in the classroom.

They have been filled with helium.When Robert lets his balloon go, it rises to the ceiling.

Why does the balloon go up to the ceiling? Is it because…

A. The air is not pushing down on the balloon.B. There is less gravity pulling down on the balloon at the ceiling. C. The pull down on the balloon is less than the push up. D. The push up on the balloon is less than the pull down.

Helium Balloon(b) Hilary puts twelve paperclips on

the string of her balloon.

The balloon stays at the same height above the floor of the classroom when she lets go.Explain why the forces acting on Hilary’s balloon, with twelve paper clips on the string, make it stay at the same height.

End of paper.

(c) What will happen to the movement of the balloon when she has thirteen paperclips on the string?

(d) Explain your answer to part (c) by describing the forces on the balloon.
