1. 3. Gather background information (finish)  Jefe: Read interviews out loud to your group  Discuss the most important piece of information from each interview & record that info in a few bullet points  2 minutes!

2. 4. Gather evidence  Materials Manager: Send your materials person up to the front of the room to test the pH of the mystery blue liquid.  While the materials manager is away: Discuss what you learned from the interviews. Come up with at least 3 ideas about what happened to Jeremy.

3. 5. Make inferences  Inferences = explanations based on observations  Make inferences about what you think happened to Jeremy.  As a group come up with a 1P explanation of what happened from start to finish -Jefe can double check crime scene  Be ready to share

4. The real story  Jeremy was doing an AP biology investigation to identify the blue mystery chemical. His jefe, Daniel, read the instructions to everyone, but Jeremy wasn’t really paying attention and didn’t hear the list of chemicals they were using (vinegar, cabbage juice, and a mystery liquid). When the Daniel asked him to take the temperature of the mystery liquid, Jeremy put the thermometer in and waited. He got bored while waiting and turned around to talk to his friend Carmen at the next lab table. While he was turned around talking, he accidentally knocked the cabbage juice indicator liquid off the table. Daniel went to go notify the teacher, but Jeremy was worried that he was going to get into trouble so he quickly tried to pick up the glass pieces. Unfortunately, he accidentally cut himself and the indicator liquid got into his bloodstream. While he was walking back to the sink to wash his cut he started to feel dizzy and passed out. Jeremy recognized the smell, it was cabbage juice, and he was severely allergic to it. The teacher ran back to help and called 911, but by time the paramedics arrived it was too late. He’d had a severe allergic reaction and slipped into a coma.

5. 6. How could this have been avoided?  With your group, list 5+ safety behaviors that could have helped prevent this accident. (Try and write them as “DO… behaviors”) Please pass forward!
