Physical Science MCA Review

1. Physical Science MCA Review **RESEARCH: With your partner, do the necessary research to complete the topic you were assigned & fill in your topic's slide. **PICTURE: Every topic needs at least ONE picture that explains your topic & any other questions asked for. **PRESENT: Be ready to do a SHORT presentation of your slide at the end of the class--both partners need to present.
