This morning, we reviewed what we discovered in our investigation yesterday. Then, we read about matter, mass, and volume on page 10. We talked about different items in the classroom having different masses and volumes. We also discussed that an item with more mass will have a stronger gravitational pull, and therefore, weigh more. We answered the two questions on page 10.
1. The balloon has more volume because it takes up more space.
2. The bag of marbles has more mass because it contains more matter.
We continued our lesson with page 11 where we read about physical properties and how they can help us identify matter. We watched a video clip that explained how properties can help us identify objects. We used the video to help us answer the question on this page:
1. The physical properties of matter can help us identify matter. For example, we know most metals are reflective because light bounces off of them.
After our learning, we returned to page 5 to evaluate our initial thinking about matter. The students should have learned that matter includes solids, liquids, and gases. We recorded our learning on this page:
After learning about matter, I agree with Curtis because I learned that I am matter, and Curtis said that solids are matter. He also said liquids are matter, and I learned that water is matter. Finally, Curtis said that gases are matter, and I learned that air is a gas.
Finally, we returned to our investigation from yesterday on page 9 and gave each object a physical property in the last column of the chart.
acrylic rod- reflectivity
paper clip- magnetism
rubber eraser- flexibility
aluminum foil- conductivity
copper wire- conductivity
wooden toothpick- other
penny- conductivity
metal rod- magnetism, conductivity, reflectivity
