Students figure out in this lesson's pre-discussion that they use their senses to determine what property of matter a given object/substance is.
I will be giving this lesson to the other first grades. I generally watch the Media Assistant perform first lesson and give the rest of that grade level myself.
I just thought of other objects to use and try for this lesson.
A coconut. Liquid and solid on the inside. The sense of hearing and seeing the size of the fruit helps us distinguish that.
A water balloon may not need to be brought into the room to be able to visualize what is in the balloon.
Inserting a solid figure into a balloon may be another idea to clearly obtain the objective that solids and gases can not be in the same space at the same time.
Percentages of air/percentages of liquid/percentages of solids.
Lesson still in the works.
