Exploring Properties of Matter

This week we are learning about properties of matter. Yesterday we talked about the word "observation" and how scientists have to make careful observations to make sense of the world around them. I placed an apple in the middle of our circle and gave students 30 seconds to observe it. Then I covered it up and asked them to describe what they saw. I charted their responses. We talked about how if a scientist had more questions he/she could observe what he/she was studying again. Then we passed the apple around the circle so that they could more closely observe it. I explained to them that we had just made a list of the properties of an object and that properties help scientists identify the objects they are studying. We learned that we can describe an object by its size, shape, color, and texture. We learned that properties describe how on object feels, looks, or acts.

Then we cut the apple open and observed it's insides. Of course we had to wrap the lesson up by tasting it.

Today we focused more on the word "properties". I brought the apple back out and we observed it again. We revisited our observation chart from yesterday. Today we specifically discussed color, texture, mass, size, and shape. We made this chart together. I based the words on the ideas that were generated yesterday. 
We had a brief discussion on the meaning of mass. We did not explore this concept in depth today because we will be talking about it more tomorrow. We watched this short video for a demonstration of heavy and light. 

We made and painted paper sack apples. After they dried we reviewed the properties of an apple and all that we had learned. Then we labeled our apples with its properties.
