Ideas from NSTA September K–12 journals

Science and Children:  Engineering and Design

Engineering and design are naturals for younger students. Just watch them play, invent things, and solve problems. The articles this month focus on these topics and how models (whether physical, two-dimensional, or mental) are important to the engineering and design process.

Science Scope: Three-Dimensional Instruction

As the editor notes,” It will take many lessons with various combinations and blendings of SEPs, CCs, and DCIs to get students to reach the competency goal of each performance expectation.” The NSTA journals show us many examples of how lessons and resources can incorporate the 3-Ds (Science and Engineering Practices, Cross-Cutting Concepts, and Disciplinary Core Ideas).

The Science Teacher: Our Changing Earth

“Stability and Change” is one of the cross-cutting concepts in the NGSS. The editor raises the question about how much responsibility human activity has in changes that we see these days–in terms of population, urbanization, transport of invasive species, extraction industries, and pollution.

  • A Rising Tide Students model the effects of global warming on the Earth’s oceans and predict sea level rise due to thermal expansion.   
  • Ocean Acidification In these six lessons, students examine the causes of ocean acidification and use a systems approach to this global problem from the perspective of several stakeholders.
  • The Resource Beneath Our Feet Students investigate how a diversity of soils supports a diversity of organisms and how changes in can affect biodiversity and the health of an ecosystem.
