This week, we continued our unit of study on Materials in Our World with a more in depth look at paper. We observed and explored several types of paper, including newsprint, tag board, corrugated paper, cardboard, chip board, wax paper, paper towel and construction paper. We spent some time discovering what happens to paper when you add water to it. We were surprised to learn that some types of paper absorb water, while others repel it.
