How many pipes are there?

• Two with the same diameter

• Two with different lengths

• Three with different diameters

• Three with the same length

How long are the pipes?

• 1m50

• 2m50

• 0.5m

• 5m

The diameters are

• 40mm, 60mm and 80mm

• 40mm, 70mm and 110mm

• 50mm, 80mm and 110mm

• 30mm, 65mm and 100mm

What is the first height of the pipes?

• 50cm

• 35cm

• 5cm

What is the name of the object he puts in the pipes?

• Water stone

• Air stone

• Fire stone

• Wind stone

What is the aim of the experiment?

• To clean the pond

• To compare the flow of each pipe

• To feed the fish

• To heat the water

Which pipe has the fastest flow at 5cm?

• 40mm

• 70mm

• 110mm

What happens to the 110 mm pipe at 20cms above the water?

• The flow is faster

• The flow is slower

• There is no flow

What is the conclusion of the experiment at 20cms above water level?

• You need a smaller diameter for a faster flow

• You need a bigger diameter for a faster flow

• There is no difference
