We weeded our school garden today.
We took out all weeds, old potatoes and snails!
We tasted some onions, cabbage leaves and garlic.
We had a look at the cress seeds we planted last week.
Here is the cress with no water (healthy for now) and the one in a plastic bag with little air (not bad)
Here is the cress with water, air and light (fantastic, tastes good too!) and the one with no light (the worst!)
So we know that plants need water, air and light to grow.
