This fun activity uses Legos to explain how photosynthesis works and is perfect for ages 11 and up.
My kids love hands-on science activities. Everything is better with Legos as well! This lesson plan combines legos and science for a well rounded lesson for kids that prefer hands-on learning.

This lesson allows students to concretely experience the photosynthesis reaction by building models of the reactants and products with LEGO® bricks. Students construct a glucose molecule, simply by rearranging the atoms of carbon dioxide and water. They can go on to make chains of starch and cellulose. The lesson teaches students that most of the mass of a plant actually comes from the air and water, rather than from soil.

There are videos, printable cards, printable lesson plans and more! You can download all of the activities HERE.
