Teaching about energy in biological processes is supported by 6 crucial concepts:

3.1 The sun is the significant source of power for organisms and the ecosystems of i m sorry they are a part. Producers such together plants, algae, and also cyanobacteria use the power from sunlight to do organic matter from carbon dioxide and also water. This develops the start of energy flow through practically all food webs.

contrasted to power Principles 1 and also 2, this principle is much more concrete and also easier come visualize. We all have straight experiences v different varieties of foods. Numerous of these concepts, together as how sunlight cd driver photosynthesis and also food webs, are generally taught in middle school and high school curricula. Educators deserve to take these avenues to tie in an energy theme v these topics.

A quantitative technique can be provided to examine the power embodied in different varieties of foods. Right here are some examples of tasks that execute this.

How Much energy is on my Plate? leader students with a sequence of discovering steps that highlight the embedded energy the is crucial to produce various species of food. Leads students with a succession of tasks that highlight the embodied power that is important to produce various varieties of food (high college or introductory-level college). The way of life Project obstacles students to dramatically lower their energy use, and adopting a vegetarian diet is one of the routes that students may elect to take. This project can be offered with middle school with college audiences.

Whenever I run professional development for science teachers about climate change, i share the CLEAN network's set of vetted resources.
CLEAN is an outstanding collection of fine vetted resources. Ours group, Classrooms because that Climate Action, incorporates sources from CLEAN when weco-create our units v teachers.
As a science education and learning researcher working carefully with preservice teachers, public school teachers and instructors in both formal and also non-formaleducational contexts I consistently recommend CLEAN as a dependable resource.
I usage it together a resource when planning professional breakthrough for teachers--both in service and pre service; and for instructors in non-formal programs. I wishevery educator were required to use and also become familiar with this exceptional resource.
This collection of CLEAN sources is always a an initial stop once I am trying to find a resource to usage in education and also outreach, and the ar I look an initial before I construct something new!
I appreciate how you've linked climate and energy education and learning to NGSS, and also have provided great searching devices - a valuable source for teachers!
I trusted both the pedagogical approach and also the said materials. Its' refresh to have a clearninghouse of details that I can trust, particularly in a pinch.
