# Draining Tank

Activity Link: Tank Draining

Student Activity Tester Comments:

1. Time required to complete the activity: 30 minutes
2. This activity can be completed by one individual in a dorm-room setting.
3. The sources of error portion of the lesson really helped me understand why my observation and my calculations were different.
4. Don't make the hole too big and do the best you can to measure the hole.

# Hot Potato!

Activity LInk: Hot Potato!  Activityon Heating and Cooling

Student Activity Tester Comments:

1. Time required to complete the activity: About 2 hours
2. One person can complete the activity, but having a lab partner is recommended
3. This experiment does take a lot of time to do and can be tedious if they do not have the proper tools like the digital thermometer or a properly working oven.
4. Can be challenging in a dorm setting.  A convectional oven is cheaper and is what I used but it can mess up the data very easily and take longer depending on how many potatoes one is using.
5. The Oneida thermometer costs $20, the potatoes can cost around$5.
6. Deriving the formulas in the experiment is very helpful as well as explaining the "lag" between the temperature of the potato and the temperature of the oven.

# Modeling a Spring-mass system

Activity Link: Modeling a Spring-mass System

Student Activity Tester Comments:

1. Time required to complete the activity: 30-45 minutes
2. One person can complete the activity, but having a lab partner is recommended
3. Set up some kind of measuring device behind the spring model. I taped paper behind the spring and marked every cm so it was easier to view in the video how far the spring was stretched down and how high it went after I released it.

# The Simple Pendulum

Activity Link: The Simple Pendulum

Student Activity Tester Comments:

1. Time required to complete the activity: 30-45 minutes
2. One person can do this without any trouble
3. Perform the experiment multiple times and average the amount of time the lock takes to get back to equilibrium.
4. Also video tape the sessions so you have an easier way to pause and record angle values as well as keeping track of time.

# An Epidemics Model

Activity Link: An Epidemics Model - under review

Student Activity Tester Comments:

1. Time required to complete the activity: n/a (no physical experiment)
2. Very easy experiment to do and is a good way to show the population increase and decrease.

# Linear Motion

Activity Link: COMING SOON

Student Activity Tester Comments:

1. Time required to complete the activity: 3 hours, because of a faulty accelerometer app.
2. This section recommends that I use something like a rolling chair or a skateboard to record my data. However, for my data collection, I decided to measure the acceleration of our school’s elevator over a span of three different levels. I began at the ground floor and calibrated our phone’s accelerometer. I then proceeded to go from the ground floor to the first floor, first floor to the second floor, second to third, then from third down to second, second down to first, and then finally first down to ground.  I highly recommend using the elevator as a means to record data opposed to using a car, rolling chair, or skateboard. The elevator is a consistent acceleration, velocity, and displacement and will show a clean curve on your graphs.
3. I did use the app that the section recommended, however, the app was the biggest difficulty especially because it doesn't record the most accurate data.
4. One person can perform the experiment, but a partner would be nice.
5. Students may require help with Excel.
