Around and Around and Around and Around......

Most science curricula are constructed so that science topics, and the key ideas associated with them, pop up repeatedly in different grades. This, known as a spiraling curriculum, is one way to develop depth of understanding of a topic. Spiraling does not mean that students engage in the same activity over and over. Rather, as they mature, they build on earlier science experiences and develop a greater depth of understanding about a topic. 

What I loved about this chapter was that they included science stories that accurately depicted a spiraling curriculum. Showing how density lessons can get more and more in depth. As children learn more and more on a topic, they will bring to the next lesson more prior knowledge then the time before, building up their understanding of the world and how things work.
