Not exact matches

Toward High School Biology — Developed with support from the U.S. Department of Education's Institute of Education Sciences and in partnership with BSCS, AAAS Project 2061 has developed and tested an innovative eight - week curriculum unit designed to integrate physical and life science concepts to help middle school students understand chemical reactions and their role in the growth and repair of living organisms.

To help make ideas about energy more concrete, for example, the new unit will use a variety of analogies from more familiar physical systems (e.g., combustion and charging a cellphone battery) to help students understand those same energy - releasing and energy - requiring chemical reactions and energy transfer when they occur in living organisms (e.g., cellular respiration, creating a charge across a membrane in mitochondria and nerve cells) where the reactions are more complex and difficult to observe.

The study notes that narrowing down that percent range requires particle accelerator experiments on water ice to more accurately gauge the number of chemical reactions that result per unit of energy deposited by cosmic rays and solar energetic particles.

Consistent with recommendations in the Next Generation Science Standards, the new THSB unit is designed to help students understand and use scientific practices of reading scientific texts, analyzing and interpreting data, building and using models, and constructing explanations along with a coherent set of core ideas about chemical reactions to make sense of interesting physical and life science phenomena.

In the high school unit, Roseman noted, similar atomic and molecular models are also used but in conjunction with bar graphs and energy transfer diagrams to help students understand that the energy changes they observe during chemical reactions are associated with changes in the arrangement of atoms.

Chemical reactions of small biopolymer sub units or complex polymer chains under the influence of traction forces and catalytic nanoparticles could be investigated with this new method.
