I've found that daily journal entries to play a crucial role in the learning process. This powerpoint consists of over 140 'Journal Entries' covering various biology concepts in accordance with California State Science Standards. Every entry includes visuals to ellicit thought. Initating class with a daily journal entry is an outstanding teaching practice, as it focuses students' attention on the desired topic immediatley.
I also include a daily science joke/comic (typically one that cooresponds with the topic for the day). This may be displayed before or after the journal entry at the beginning of class. These are available on TPT as well.
