Chemical Reactions: A World of Reactions

Science ObjectDigital resources are stored online in your NSTA Library.

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.

I really liked the information this had. It was very detailed. I feel like teachers can use this information to refresh their memory and then condense the material for their students.

I really enjoy Science Objects. In 1-3 hours, the Chemical Reactions: A World of Reactions Science Object will help me re-learn, refresh, or learn for the first time some critical science concepts I will have to know to obtain my Science Educator credentials. I appreciate that I can complete them at my own pace, and that, if used as park of a SciPack, I have access to a content expert to go to for help. The NSTA Learning Center Science Objects are really beneficial!

I used this as a prep for the PA Keystone Tests with great success. We don't have the facilities to do much chemistry in my school and so this really filled a gap! It increased student scores in the standardized tests and also the classroom scores. We did the textbook exercises and then once a week did the science objects. 100% Great job!

This was a good refresher for middle school chemistry. The review questions with explanations help to check understanding as well.

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.

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.

This science object was very relevant in that it uses so mant real-world examples to foster understanding!

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.

Material, although written for adults, would be useful for highly able or interested students. If you need a review, I recommend using this object.

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.

The integration of short audio clips, combined with interactive material, was engaging and concise.

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.
