Newton's second law tells us about how mass and weight are related.
Click on Tab 4
Go through 'The Laws of Motion' and 'Forces in Action'
When you are done, Go to Tab 2 and click on the Gravity Rules Forum Discussion.

Today is a workday.
If you don't know what to do with the pop, try some of these.
*measure the pH of the pop
*shake it for a few minutes, and measure the pH again
*compare the pH of cold and warm pop
*measure the pH of the pop, add water, and watch if the pH changes.
*filter the pop and measure pH
*filter the pop through soil and measure pH changes
* try to measure a volume difference in the pop

Models for Today
Carbon Sequestration Model
What happens to carbon dioxide trapped in the water or in the soil? You will need to design a lab to try to find out. Materials for the lab will include balloons (upon request), pH paper to test the acidity. You can try to measure the temperature of different pops and determine the mass of CO2, you can measure the acidity of different pop, you can do something else. But you must come up with a model that allows us to understand how carbon dioxide (found in the pop) can be contained in the soil or affect the acidity of your liquid.
**You will turn in a lab procedure and a video for this model**
Geochemical Cycles
We will use a poster for our model. Create a poster that details the carbon cycle, with arrows, and include the role of humans in the cycle. Now use a second color of ink and draw the nitrogen cycle on this system. Finally, use a third color of ink and highlight the water cycle.
Use this model to answer the following questions by drawing in a FOURTH item, a hog confinement farm. Then draw on the model as needed or explain these questions on the back.
A: How will the hog confinement farm affect the nitrogen cycle. Draw in arrows to connect your farm to the nitrogen, water, and carbon cycles
B: Show how the hog farm could use its materials to produce energy.
C: Hog confinement farms are required to have manure management plans. Why? How can this affect the water cycle? Think of phosphorous and local creeks and rivers.

Planning for Change
Whether we have climate change or not is a futile argument, because people basically argue statistics.
A more effective use of time is to think about planning for emergencies. This can take many forms. You will focus on FOUR of the following plans. Next week, we will build models of the plan of some type. You MUST do the planning for the two choices marked with a **
