 Each day they will follow their water plan and note down the height of the plant. At the end of the experiment the student(s) can make a table in their notebook(s) from the readings saved on the micro:bit and the corresponding height of the plant.​

 The student(s) can then share their results with the class to create a full table of data and analyse how a plant's height is affected by how it is watered.​
