In this science chapter I have learned that heat and matter are 2 things that are valued! For example: without heat we would be freezing! One thing that I liked about this chapter is that Mr. Phillips made it fun. One thing that I disliked about this chapter is that we did so many worksheets. A few things that I learned in this chapter are that a convection current carries air in a circular motion. I also learned that workers have to leave space between tracks when they build railroads. When the tracks heat up they expand. If the workers didn't leave any space between the tracks, the tracks would buckle over each other. My favorite thing that we did in this chapter was the popcorn activity=http://!!!!!

      We have learned a lot in this chapter, but there are still a few things undiscovered. What do you think they are?
