Description

Science Objects are two hour on-line interactive inquiry-based content modules that help teachers better understand the science content they teach. This Science Object is the first of four Science Objects in the Chemical Reactions SciPack. It explains that chemical reactions occur all around us, for example in health care, cooking, cosmetics, and automobiles. An enormous variety of biological, chemical, and physical phenomena can be explained by changes in the arrangement and motion of atoms and molecules. An atom's electron configuration, particularly the outermost electrons, determines how the atom can interact with other atoms. Atoms form bonds to other atoms by transferring or sharing electrons. Carbon atoms can bond to one another in chains, rings, and branching networks to form a variety of structures, and complex chemical reactions involving these molecules take place constantly in every cell in living objects.


Ideas For Use

Science Objects are two hour learning experiences teachers can use to enhance their understanding of a particular scientific concept. Teachers can access any topic “on demand” from the Internet. Topics are based on the science literacy goals in the national standards (NSES, Science for All Americans, Benchmarks, and the Atlas of Scientific Literacy) and tied to state standards.

Each Science Object provides an understanding of the science content by providing a structured set of learning experiences through simulations and practice assessments. Science Objects challenge teachers to explore and explain real world phenomena and are founded on the principle that learners must be challenged with a problem, observation, data, etc., in order to develop scientific understanding. Science Objects utilize the five phases of inquiry-based learning: Engage, Explore, Explain, Elaborate, and Evaluate.

Learning Outcomes:
  • Identify examples of the many chemical reactions that occur all around us.
  • Explain the source of the enormous variety of biological, chemical, and physical phenomena that surround us.
  • Provide examples of bonds formed between atoms when outer electrons are transferred from one atom to another, and when electrons are more or less shared between them.
  • Provide examples of how carbon atoms can bond to form a variety of structures.
  • Describe the significance of carbon-based structures for life.

Customer Reviews
Chemistry Review
  Reviewed by: Angela Dillon on April 9, 2013
  This was a good refresher for middle school chemistry. The review questions with explanations help to check understanding as well.

Simple & Clear!
  Reviewed by: Christian Nowell (New York, NY) on November 18, 2012
  This Object presents chemistry basics related to Biology in an extremely easy to understand and intuitive manner. The examples and interactive exercises reinforce concepts well. The progression from simple to complex concepts makes it easy to quickly build your understanding.

Review on Chemical Reactions: A World of Reaction
  Reviewed by: Ronaldo Relador (Bowie, MD) on February 29, 2012
  There are so much information that present themselves in a new light. This is something every physical science teacher should see and introduce to his/her classroom.

A New World
  Reviewed by: Duane Little (Washington, DC) on November 1, 2011
  This science object was very relevant in that it uses so mant real-world examples to foster understanding!

helpful

  the interactive activities and animations were helpful in explaining difficult concepts

Understanding Chemical Reactions
  Reviewed by: Patricia (Arlington, VA) on May 17, 2011
  This Science Object starts with warm-up questions to lead students to ponder chemical change, to express chemical reactions in words and with equations, and to delve into the nature of molecules and their varied types of interactions. The simulations included address common errors in thinking, offering ways to model and extend bonding theory to chemical reactivity. The visualizations clearly illustrate the models and would be very helpful for students whose understanding is challenged if only textbook reading is offered. The questions proffered throughout serve as excellent assessment probes to use with students. Use this material for personal enhancement, as a design for classroom presentations, and as snippets of interactive learning to enliven learning about chemical reactions.

Great Overview of Bonding and Reactions
  Reviewed by: Latanja Thomas (Arlington, VA) on November 10, 2010
  Material, although written for adults, would be useful for highly able or interested students. If you need a review, I recommend using this object.

SciPack Review
  Reviewed by: Lara (New Haven, CT) on November 3, 2010
  This SciPack series is a first stop for anyone who wants a review of basic chemistry content before teaching about chemical reactions. The tutorial is very user-friendly, engaging and allows you to progress at your own pace.

Chemical reactions review
  Reviewed by: Linda Bowin (Gulfport, MS) on February 26, 2010
  Most of the information is quite useful. The review on Lewis dot structure is very good. Two statements were potentially misleading when declared false by the check step in a quiz for section three and another in section four. These were: atoms were involved in associations involving more than 2 atoms, and that the achievement of a full complement of electrons in the outer shell produces stability. Otherwise, I found the material to be rather straightforward and correct.
