This week we have begun our new Theme Studies focus, Plants and Soils.
We began our investigations by brainstorming things we already know about plants. We put this information up on a Need/Have/Are chart on the Smartboard to provide a framework to our thinking.
Next we began learning about the different parts of plants. We labeled a plant diagram and watched a short video that explained the function of each part of the plant. This gave us basic knowledge that we could build on. We are now spending a bit more time on each plant part to learn about it more thoroughly. Yesterday we learned about roots and how there are two different types of roots, tap and fibrous. Today we began looking more at stems.
We began an experiment to see how a stem brings water to the leaves. Each table placed a stalk of celery in a cup of water. We then added ten drops of red food colouring to the water and stirred. As a class we came up with three possible hypotheses for our experiment:
1) The celery will absorb the coloured water and turn red.
2) The celery will absorb the water, but not turn red.
3) The holes inside the celery will turn red.
Tomorrow afternoon we will revisit our experiment to see what our results are.
