KMG-This is a great charting activity with plants and can be used toward the end of the lesson to ensure that the students understand the lesson. The parts of the plant and what the plants give are more complex complex concepts for kindergarten, but it is still okay to introduce and teach it. I just will not require reciprocation of the information in order to achieve mastery.
I want to connect this to the PYP attribute definition: internationally minded people strive to make the world a better more peaceful place. We start by investigating in our classroom how to make it more peaceful and then take it globally.
