Spring SAVY 2014, Week 2 – Where’s the Beach? (Kindergarten)
We had another great day at SAVY! We revisited our list of systems and categorized the systems into different groups. We brainstormed nonexamples of systems and this took some careful thought. The students demonstrated a good understanding of systems and we made generalizations about systems. These include:
All systems have boundaries, elements, inputs, outputs, and interactions.
Systems can be productive or dysfunctional.
Systems are interdependent.
This will help us in understanding more about the beach as a system and assist us in solving our problem in the town of Dunesville.
We heard the story of the 144 year old Cape Hatteras lighthouse. This is an example of how a beach system is sometimes dysfunctional. We found out about the proposed children’s camp on the beach in the town of Dunesville. All new plans have been put on hold because of fears of beach erosion. It is up to us, the members of the town council, to approve the camp. We broke up into two small groups and developed a need to know chart to help us solve our problem.
Students were presented with the concept of “weathering”, and they then had to decide what this process would do to rocks and and how this could affect nature and a beach environment. We performed several experiments that looked at what happens when rocks freeze, when exposed to chemicals, when they are sanded or filed, or when they are tumbled.
Next week, we will examine the nature and actions of sand and soil by conducting several experiments designed to help us make an informed decision about the future of the camp. We will also learn about the effects of weather on beach erosion. We will model and graph the process of beach erosion over time.
Research and find out how many states in the United States have a coastal area.
Consider mountains as a system. Draw and label the mountain system, showing boundaries, elements, inputs, outputs, and interactions.
Have a great week!
