Question

Structure of matter lab activity​

Answer 1

Answer:

Each of the more than 100 elements of matter has distinct properties and a distinct atomic structure. All forms of matter are composed of one or more of the elements. As a basis for understanding this concept:

a.Students know the structure of the atom and know it is composed of protons, neutrons, and electrons.

Making models of atoms

Understanding atomic scale - Powers of Ten (Sourcebook for Teaching Science 8.2)

Linking, embedding, and dowloading chemistry videos for use in the classroom

b.Students know that compounds are formed by combining two or more different elements and that compounds have properties that are different from their constituent elements.

Chemical reactions

Simulations of chemical reactions

Faraday's candle activity - observations of a candle (what happens to oxygen)

c.Students know atoms and molecules form solids by building up repeating patterns, such as the crystal structure of NaCl or long-chain polymers.

crystal models

Use of videomicroscopy to see crystals

polymer activity (Hands-On Chemistry 3.5.2)

d. Students know the states of matter (solid, liquid, gas) depend on molecular motion.

Simulations of states of matter

Plasma - Tesla coil, Plasma Lamp,

e.Students know that in solids the atoms are closely locked in position and can only vibrate; in liquids the atoms and molecules are more loosely connected and can collide with and move past one another; and in gases the atoms and molecules are free to move independently, colliding frequently.

f.Students know how to use the periodic table to identify elements in simple compounds.
