So we figured out that air and water are matter because they have weight. We also figured out to represent air as pieces with lots of empty space around them. This will hopefully help us model how plants get the matter they need to grow!
But light is throwing us for a loop because maybe our scales just don't have the capacity to register the small amount of matter light may give a plant. But if our scales are actually ok (which Mrs. Brinza thinks they are!), what exactly might light give to plants, if not matter.
Mrs. Brinza set out to help us figure some stuff out about light using a flower toy, a radiometer, and a calculator. We even watched a movie about chocolate in the sun!

And from all these investigations, we figured this out...
And now that we now that energy and matter must be different things, what does this mean for animals and how they get their energy? How can we represent this?
