Mung beans need 3-5 days growing time and need to be kept in a warm, dark place. Sunflower seeds need about 2-3 days growing time. The sprout will taste bitter if left to develop green leaves. After 2-3 days of rinsing and draining, alfalfa, lentil, mung bean, radish and sunflower sprouts will burst through their hulls. Hulls are not harmful, so you can leave them on if desired.
Sprouting seeds is an activity that takes place over several days.
This time can be used to go through some of the other activities in this pack, if desired. Once the sprouts are ready, the activity sheets can start to be filled in. On their activity sheets, pupils are asked how many sprouted pulses they get from the weight of two teaspoons of dried. This activity includes some maths that can be differentiated for ability of pupils. Alternatively, as sprouts grow and green at different rates, a different sprout can be used to demonstrate a different calculation.
