Activity 1.1.2 Simple Machine Practice Problems
Introduction
In the last activity, building and using simple machines and making measurements of forces and distances gave you concrete examples using mechanisms. Just from a good sketch, however, an engineer can deduce how a mechanism will transform forces and distances from input to output -- from effort to resistance. Making a good sketch of a mechanism and making accurate predictions based on your sketch of a mechanism are great problem solving skills that will help you design mechanisms for a particular task.

Project 1.3.3 Thermodynamics
Introduction
Think back to the last time someone complained about a door being left open. What did you notice about the temperature within the room as a result of the open door? In Activity 1.3.3 you will investigate the effects of work, thermo energy, and energy on a system, as in the case of the room with the door left open.
