To begin this activity, students will need to have an idea of how much water each plant gets with each watering. Provide small measuring cylinders so the students can see 20, 50, and 10 millilitres of water. This will give them a benchmark for estimating the solutions to go on the calendar.
Students will need to work out the watering dates in an organised manner. Using a different coloured counter for each plant and moving it on the calendar will help. Writing the dates in an organised way can also help.
