Explaining Matter with Elements, Atoms, and Molecules: Evidence for Atoms and Molecules

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 third of three Science Objects in the Explaining Matter with Elements, Atoms, and Molecules SciPack. It explores the evidence for atoms and molecules, and looks at the way atoms and molecules are arranged and behave in different types of matter (solids, liquids, and gases).

I really enjoy Science Objects. In 1-3 hours, the Explaining Matter with Elements, Atoms, and Molecules: Evidence for Atoms and Molecules 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 very beneficial!

This resource and the ones like it are particularly valuable for me for several reasons. First, I like the table of contents off to the left, which all ow me to keep track of what is coming up and see the entire lesson at once. Also, it is multisensory...engaging several senses. Finally, they are self paced, which I really need with my busy lifestyle.

I felt the information was well designed and had a logical flow. Furthermore, I enjoyed the interactive component that reinforced the material taught.

This inquiry-based resource focused on the evidence of the existence of atoms and molecules provides the concept of matter greater value in a learner. The presentation is very comprehensive.

I loved learning how scientists through history came to make models in order help them understand the process of atoms and . I especially found the portion on diatomic elements very useful in extending my conceptual knowledge.
