Leaf Veins

Thursday student categorized leaves according to the three main types of veins found on them. This transitioned the learning towards understanding about xylem and phloem, and that some tubes (veins) in plants take water up from roots and others take sugars (nutrients) made in leaves to the rest of the cells in the plant. We then set up an experiment with wheat seeds, placing them on top of a paper towel inside a straw. We are testing to see if plants can grow without soil. The experiment is designed so that no water can be evaporated and we will be able to measure how much water is being taken up through the xylem into the plants.
