Course Information

Description

This course introduces fundamental concepts in chemistry and biology. Topics in chemistry include stoichiometry, acids and bases, aqueous solutions, gases, thermochemistry, electrons in atoms, and chemical bonding. The course also examines biological molecules, the transfer of information from DNA to RNA to protein, and cell structure and signaling.

Course Notes

For students with little or no previous study of chemistry or biology. This course assumes fluency with high school algebra. LPS A gives solid preparation for Life Sciences 1b and Physical Sciences 11.

Class Notes

During April registration, students should enroll in the placeholder discussion (DIS) and laboratory (LAB) sections. We will collect preferences and assign students to sections in August.
