CHEMISTRY
Unit 2: Matter and Energy
Introduction:
More than 1200 species of bamboo belong to a family of grasses that includes wheat and
corn. In tropical regions, bamboo plants grow rapidly to great heights. The tender shoots of
some bamboo plants are a favorite food of pandas. People use the woody stems of mature plants
to make furniture, fishing rods, and flooring. Because bamboo is inexpensive and abundant,
disposable chopsticks are usually made from bamboo. Bamboo has properties that make it a
good choice for use in chopsticks. It has no noticeable odor or taste. It is hard, yet easy to split,
and it is heat resistant. In this section, you will learn how properties can be used to classify and
identify matter.
Learning Targets:
1) I can explain the purpose, history, and importance of the metric system. I can accurately
complete metric  metric conversions and English  metric conversions.
2) I can classify substances as elements, compounds, and mixtures using observations of
chemical and physical properties
3) I can classify unknown substances using physical and chemical properties and changes
4) I can describe forms of energy and their transformations.
5) I can justify the law of conservation of energy through, potential energy diagrams, phase
change diagrams, and observation of chemical reactions.

Additional Materials may be assigned periodically throughout the unit
Schedule & dates are subject to change according to teacher discretion.
Assignments are due at the beginning of class on the DUE DATE. All Late work will be penalized 10% each
day it is late and will not be accepted after 5 school days. Make sure you submit assignments worth points by
the DUE date.
Re-takes on unit exams are available before the next summative assessment for students that maintain a
minimum of 80% on formative assessments, which include bellwork, homework, and exit slips.
