Momentum -
Will and I reviewed the formula he has been working with this year. We worked on determining what was asked in a word problem, identifying what was given, and then finding the formula to find a solution. We examined word problems for finding momentum, impulse, and force. We also discussed some Olympic sports that have been taking place, including curling, snow boarding and bobsledding. Will was tasked with explaining how energy moves through the process for each sport, and where force is met with traction for the benefit and detriment of the athlete.Homework: Finish the work problems started in class.

Energy and cars -
Will reviewed how energy is either stored or converted. We walked around the school grounds, and he identified where energy was actively being stored or converted. We also reviewed how momentum is manifest in his daily life, especially while driving. We then examined how energy enters and moves through the car system. We then discussed how humans use oil (stored energy) and convert it into gasoline to use in his car. We watched an animation of a combustion engine, to see how energy is transformed from chemical, stored energy, to kinetic energy in the movement of the car.

Impulse and momentum -
Will was quizzed on momentum. We reviewed how different materials affect momentum, and the importance of ‘follow-through’. We examined how a person can break a board with their hand, and the energy flow involved. We then explored how energy moves from an impulse into momentum, in a variety of situations.

Momentum-
After reviewing his homework assignment, Wlll worked some momentum problems, where the force of gravity, the speed, direction and mass were given. Considering how energy flows through a system, we discussed the probability of superman having the ability to catch Lois Lane, and then throw her to safety. We then examined the impulse that initiates momentum in a system, and discussed why the impulse has the same force as the momentum.

Momentum -
Will and I discussed momentum. We did some thought questions about the energy flow during some iconic superman actions (holding up a crumbling building, or catching Lois Lane during mid-fall). Will followed the flow of energy, and wondered what happened to the momentum. We reviewed the formula for momentum, and then determined the momentum of the Titanic. We also examined the momentum distributed after a collision between and bug and a bus, traveling down the highway. Homework: find the momentum of several objects, based on their descriptions.

Impulse and momentum -
Will was asked to tell me the formula for momentum. We then drew our attention to the force that precedes momentum, which is called impulse. I described impulse for Will and he added it to his vocabulary sheet, including the formula. We reviewed the formula and units related to force and velocity. We then reviewed the metric system and the differences between the American system of measures compared to the metric. Will was tasked with telling me why all science is in the metric system.

Physical Science:
Energy Flow and Entropy-
Will was tasked with identifying the flow of energy through various scenarios where a system required energy to change from type to type. We discussed the ways entropy is expressed within each system. We started with the change of water from a solid, to a liquid, to a gas. The molecular structure becomes more disordered as this happens, indicating an increase in entropy. Finally Will was asked to provide examples of a system from a description of energy flow or entropy increase.

Entropy -
Will and I reviewed his test together, and discussed the flow of energy through a system. I then introduced the first and second laws of thermodynamics. The first reiterated that energy is conserved, and the second states that heat cannot flow from cold to hot. We watched a short film that shows how the high energy of molecules is absorbed by slower molecules in a mixture. We examined some energy flow examples, to illustrate that some heat escapes from a system each time it is converted, and that this disorder is entropy.

Energy Flow -
Will was tested on the flow of energy through a system. He finished most of the test, he will complete the remainder at home. Homework: complete progression of energy list.
