Bellwork Sept 15, 2015SPI 0807.Inq.5: Bias and Error
1. Which part of the experiment is most likely the source of error in this investigation?
2. The student concluded marble diameter had no affect on crater depth. Which is the most likely reason this conclusion is flawed?
3. A student investigated how the mass of a plastic disk affected its motion. The student pushed five similar plastic disks, each with a different mass, across a wooden floor. The student recorded the distance each disk traveled. The investigation was repeated five times. The student concluded there was no relationship between mass and distance traveled. What is the mostly likely source of the error in the investigation?

Different student timing
Different marble masses
Different forces of push across the floor

Date
1) A game company is working on a new computer game. Their programmers are now writing the software. What engineeringdesign process (EDP) step is this?2) After the software is written, they will hire gamers to play itlooking for errors in the software. What EDP step will that be?
Instructions1) First click on "View" from the top-menu bar.2) Then click on "Slide Show" from the drop-down menu.3) Then use the right-arrow button on your keyboard to advance through this presentation.

The Iron Man Movies and the Engineering Design ProcessBillionaire genius and weapons designer Tony Stark is captured
by terrorists, and they want him to build a super-weapon. Instead he builds an armored exoskeleton to fight them.

Step 1: Identify a need Why did Tony Stark build the "Iron Man" suit? Step 2: Develop Possible Solutions What are some other options he could have built instead?
Step 2A: Pick the best design Do you think the "Iron Man" suit was the best design option?
Step 3: Make a prototype Where and how did Tony build his prototype(s)Step 4: Test the prototype Where and how did Tony test his prototype(s)Step 5: Modify and re-test the prototype How did Tony modify his prototype to make it work better?
