Chemistry is the study of the structure of matter and the changes
or transformations that take place in it. Learning about the makeup of
substances gives us knowledge about how things go together and how they
can be taken apart. Learning about changes in substances is important
for several reasons: changes can be controlled to produce new materials;
changes can give off energy to run machines. The Mixtures and Solutions
Module has four investigations that introduce students to these fundamental
ideas in chemistry.
Students will
|
• |
Gain experience with the concepts of mixture and solution
and the physical properties of substances that are used to identify
them as mixtures and solutions. |
| |
• |
Gain experience with the concepts of saturation and
supersaturation. |
| |
• |
Identify properties of common solid, liquid, and gaseous
substances. |
| |
• |
Understand that during chemical reactions, atoms rearrange
to form products with different properties. |
| |
• |
Learn that all matter is made of very small particles
called atoms and that atoms combine to form molecules and compounds. |
| |
• |
Know that the 90 naturally occurring elements and
their combinations account for all the varied types of matter in
the world. |
| |
• |
Understand that the periodic table organizes the elements
by their chemical properties. |
| |
• |
Plan and conduct simple chemical investigations. |
| |
• |
Use measurement and appropriate tools in the context
of scientific investigations. |
| |
• |
Record data, develop scientific evidence, and draw
conclusions from that evidence. |
| |
• |
Acquire vocabulary associated with chemistry and the
periodic table. |
