Tutorial on using the Measuring Cylinder Interactive Teaching Program.

Set the maximum to 200 and the scale to 10.

Turn the tap on and fill the cylinder up to 140. To turn the tap on click on

and to stop the tap click on            again.

Show the current volume of liquid is 140 by clicking on:

Hide this value after showing the children.    Click on        to reveal the marker.
Move the marker to 140.

(You can also use the control arrows          to move the marker up or down and to
reset it to the centre of the scale).

Turn the tap on again to approximately 170; make sure that it is not exactly 170.

Q: Is the volume of liquid exactly 170? Can you estimate what the exact
volume of liquid is?

Change the scale to 2.
Q: Does this help us to accurately read the volume of liquid? Why?

Click on the        icon to show the actual volume of liquid.

Q: If I only want the volume of liquid to be 100. How much liquid would I have
to drain out?

Click on the outlet icon         to reveal the drain tap. Click on the control panel
icon

to reveal the outlet control panel.

Use the arrows to set the amount of liquid needed to be drained to reach the required
volume of 100. If you have 174 you will need to set the drain control panel to 74.

Use the tap to start the flow. The water will stop draining when it the entered
amount.

Reset the Measuring Cylinder Interactive Teaching Program. Set the maximum to
100. Set the inlet control panel to 37.

Using the arrows enter the required amount of 37.

Turn on the tap to enter the amount of liquid. The tap will automatically let in the
required amount of 37.
Q: How much liquid would I have to add to reach 76?

Using the red marker model counting up to 76. An increase of 3 would take us up to
40, then an increase of 30 would take us up to 70 and finally an increase of 6 would
reach the required amount of 76. Therefore we would need 3 + 40 + 6 = 49.

Using the inlet control panel         add 49 to the amount of liquid showing that this
would give us a total of 76.

If you are using an Interactive Whiteboard you will be able to annotate over the
screen using the whiteboard tools as shown below.

Q: How much liquid would we now need to release to reach 18?

Demonstrate as with previous example.
