Classwork / Homework

1. Partner exercise - articles about particular technology systems (i.e. Hubble, Maglev Train, etc.) and students must:

1. Describe the system outputs – what are the desired/undesired outputs?

2. Describe the operation of the system in terms of the 9 core technologies.

2. Answers should be written up. 3 or 4 groups will be chosen at random tomorrow to give presentation. 3-minute maximum. Teacher will ask questions. IOT
