Measuring plants up to 100cm.
Click the waterdrop to water the plant.
Click the sun to give it sunshine and make it grow.
Measure the height of the plant and enter the value into the keypad.
There is a guide you can slide up and down to help you.
If you get it right the height will appear in the table.
To make the plant grow again click the waterdrop again.
NB: Problems with sound - currently some of these games lose their sound if you open another tab. I don't quite know what's causing this, but am investigating. If you lose sound and want it to return you may need to refresh this page.
