Noticing a pattern can be the first step to asking scientific questions. It has to do with classification of similarities and differences. Young children can find patterns, and then when they go to school need to learn way to recognize and record patterns. Children progressively get better as they get older and start to relate patterns.]]> 2020-01-21 01:42:19 UTC https://padlet.com/nicole_burnside5/rjxuohxlyenx/wish/433800741 nicole_burnside5 https://padlet.com/nicole_burnside5/rjxuohxlyenx/wish/433803281 Compelling questions are often about how or why something happens. This helps us uncover connections that will help us make predictions. "Any application of science, or any engineered solution to a problem, is dependent on understanding the cause-and-effect relationships between events" (p 87). One goal for students is for them to see that events in the world have causes. In younger grades, students ask, "What is causing this?" In older grades, students ask "why" and "how".]]> 2020-01-21 01:54:15 UTC https://padlet.com/nicole_burnside5/rjxuohxlyenx/wish/433803281 nicole_burnside5 https://padlet.com/nicole_burnside5/rjxuohxlyenx/wish/434222238 Systems and processes vary in size, time, amounts, and relations. The ways that things work may change with scale. There are macroscopic (observable) scales, scales that are too fast or too small, and those too slow or too big. You must have some insight into measurement and order of magnitude. Understanding the concept of scales is critical in understanding phenomena. Eventually units of measurement are introduced and students can also estimate.]]> 2020-01-21 19:42:43 UTC https://padlet.com/nicole_burnside5/rjxuohxlyenx/wish/434222238 nicole_burnside5 https://padlet.com/nicole_burnside5/rjxuohxlyenx/wish/434285078 "A system is an organized group of related objects or components that form a whole" (p 92). Systems often depend on other functioning parts of the system. Students' ability to model systems progresses as science instruction does. Students should be asked to show thinking through drawings and diagrams with written descriptions. Discussions should include interactions within a system. Student models help clarify knowledge and questions students have.]]> 2020-01-21 21:49:06 UTC https://padlet.com/nicole_burnside5/rjxuohxlyenx/wish/434285078 nicole_burnside5 https://padlet.com/nicole_burnside5/rjxuohxlyenx/wish/434295615 The function of systems depends on shapes, relationships of key parts, and properties of materials. Exploration of this relationship between function and structure begins in early grades through investigation. It may start with shape and stability and as they get older, they look at human body functions and structures and how they relate.]]> 2020-01-21 22:22:36 UTC https://padlet.com/nicole_burnside5/rjxuohxlyenx/wish/434295615 nicole_burnside5 https://padlet.com/nicole_burnside5/rjxuohxlyenx/wish/434300031 "The ability to examine, characterize, and model the transfers and cycles of matter and energy is a tool that students can use across virtually all areas of science and engineering" (95). Understanding this core idea of energy and matter changing in a system is informative in life, earth, and space science. This concept is not taught until 3rd grade. Younger grades focus on conservation of matter.]]> 2020-01-21 22:39:23 UTC https://padlet.com/nicole_burnside5/rjxuohxlyenx/wish/434300031 nicole_burnside5 https://padlet.com/nicole_burnside5/rjxuohxlyenx/wish/434300902 Science has to do with understanding change in systems, and technology creates and controls change. Stability means that the system will return to or stay in stable condition. Very young children note change and stability. In school, children learn to ask why or why not something changes. Students come to understand that stability and change relate to one another.
