The things i liked about science was that we learned so far about about heat and matter lesson was the expansion and contracting.The thing that interested me in this article was that the bridges and railroad tracks use the separations for expansion and contraction.The other things i didn't like was the the radiation lesson.I liked the popcorn experiment i think that was a good example of heat and matter.I also liked the food coloring test i think that was another good example of the Heat and Matter chapter.
