DO NOW: Independently think for 30 seconds. Discuss with partner for 30 seconds. Write down a solution in your notebook. Then raise your hand. There is a large boat in the middle of the ocean. Several corpses are floating nearby. What happened?

What false assumptions did you make? Some solutions: 1. A group of people were on an ocean voyage in a yacht. One day, they decided to go swimming -- they put on their swimsuits and dove off the side. They discovered belatedly that they have forgotten to put a ladder down the side of the yacht and were unable to climb back in, so they drowned. 2. The same situation, but they set out a ladder that was just barely long enough. When they dove into the water, the boat, without their weight, rose slightly in the water, putting the ladder just out of reach. What false assumptions did you make?

That was a FALSE ASSUMPTION STORY. Illusions are often caused by false assumptions that you are making about a situation. You often don’t even realize that you’re making an assumption! Identifying your false assumptions is important in science. If you’ve made a false assumption, you haven’t accurately described the situation. We will practice these almost every day as our DO NOW activity. Your job is to identify the false assumption.

Please turn to your learning partner and share one thing that you are proud of from this school year.

Please put your name tent up where I can read it!

REMINDERS Last week you received some papers that need to be signed / returned. They were on colored paper. Safety contract Permission letter / Blog letter

REMIND 101 I use REMIND 101 (now just called ‘remind’) to send text message reminders. You should sign up. Here’s how: Send a text message to the number 81010. The message you send depends on your class period: 1st: @cater1st 2nd: @cater2nd 3rd: @cater3rd Etc …

Rank the scientific reliability of seven evidence types LEARNING OBJECTIVE Rank the scientific reliability of seven evidence types

Evaluate the reliability of eyewitness testimony LEARNING OBJECTIVE Evaluate the reliability of eyewitness testimony

AGENDA FOR TODAY Do Now: false assumption story. Reminders “Forensic tools: What’s reliable and what’s not so scientific.” Create a class reliability chart for 7 evidence types. Rank your observation skills / Basketball video / rank again TED Talk: The problem with eyewitness testimony Cornell notes Cornell summary / share summaries (maybe) Article & socratic seminar

Forensic tools: What’s reliable and what’s not so scientific. You will receive a short article that discusses one type of evidence. The top section of the article is the same for everyone, but the bottom part depends on which number you received. Read the article, then do the “INDEPENDENT” section on your paper. --- (we did all of that already) --- Go to a lab table based on your article number. Do the “GROUP” section on your paper. Everyone in your group needs to agree on the same number and same supporting quotes. Be prepared to share what you have written.

Let’s put it all together in an EVIDENCE RELIABILITY chart… We need 2 volunteers to create & organize ONE large chart for the class. REQUIREMENTS FOR THE CHART: It needs to look better than the one from last period. Title and class period on the front. Numbers 1(unreliable) – 10(extremely reliable). Each article/evidence type must end up at a different number. Tape or paste EACH ARTICLE on the chart at the appropriate number. We will discuss to decide where each article goes.

Reflect on learning… STAND UP AND DISCUSS Reflect on learning… STAND UP AND DISCUSS. SIT DOWN WHEN DONE DISCUSSING. What surprised you? What type of evidence do you want to learn more about? Besides this class, how might this information be valuable to you? What other questions or comments about this lesson do you have?

Rank your observation skills from 1 (weak) – 10 (strong) LEFT PAGE Rank your observation skills from 1 (weak) – 10 (strong) Explain why you chose that number.

NOW OBSERVE THIS VIDEO… We will watch a video of some people playing basketball. The movie will give you some instructions before it starts. Please follow the instructions & remain silent during the movie. http://viscog.beckman.uiuc.edu/grafs/demos/15.html http://www.youtube.com/watch?v=vJG698U2Mvo

Video Background This video was made as part of an experiment designed to test people’s “inattentional blindness” In the original study at Harvard, only 42% of the people noticed the gorilla walking through the scene. **DISCUSS WITH PARTNER: why are we watching this video? This video illustrates the unreliability of eye-witness testimony, and the importance of observation to forensic scientists

Are you still skeptical? A lot of people have already heard about or seen the gorilla video. Here are some more videos where I guarantee you will miss something that seems obvious: http://www.theinvisiblegorilla.com/videos.html#tryit

Again, rank your observation skills from 1 (weak) – 10 (strong) LEFT PAGE Again, rank your observation skills from 1 (weak) – 10 (strong) Did your number change? Why or why not?

TED TALK: THE PROBLEM WITH EYEWITNESS TESTIMONY http://www.npr.org/2013/11/29/182671574/can-eyewitnesses-create-memories As we watch the video, write Cornell Notes Essential Question: What is the problem with eyewitness testimony? We will stop every 5 minutes to share notes with our learning partners. After we are done, we will write summaries -- be prepared to share yours with the class.
