Recap:
In 6th grade we used the demonstration table to model the water cycle for the classes. Students described how the cycle worked while watching clouds form within our model and then saw those same clouds begin to cool and fall as rain. The one question that came up was, how do rain drops form? I pointed out that water vapor molecules are much too small to form into larger drops and have to have a nucleation point. These points are microscopic bits of dust and smoke or other pollutants in the atmosphere that allow water vapor a site to gather and form into larger drops. From the USGS website: "For precipitation to happen, first tiny water droplets must condense on even tinier dust, salt, or smoke particles, which act as a nucleus. Water droplets may grow as a result of additional condensation of water vapor when the particles collide. " The USGS site is an excellent reference source.
In 7th grade, students worked on solving a mystery; how did Mrs. Kruse fall down the stairs and cut her hand? Students became forensic scientists at the scene collecting evidence and then analyzed the unknown materials found to determine if it was plant or animal cells. Students also got to practice their knowledge of the cell by going to the white board and writing in terms. This exercise demonstrated that they NEED TO SPEND MORE TIME STUDYING!
8th grade students learned how to manipulate parts of a scientific formula using the triangle formulas sheet. I gave them the 5 step problem-solving method and reminded them that, when they complete a problem, I expect to see all 5 steps written out neatly on their paper FOR EACH PROBLEM. This allows me to go back through their work and pinpoint where they made mistakes. The 5 step method is:
1. Identify and write down the formula you will use.
2. Identify their known and unknown variables and write them down including the units!
3. Plug their variables into the formula, including the units!
4. Solve the problem and make sure they have the correct units!
5. Circle the answer with the units!
EXAMPLE:
You have a cube composed of an unknown metallic substance and it has a mass, determined by using a scale, of 35.7g. By measuring the length (cm) x width (cm) x height (cm) of the cube using a ruler, you determine the cube has a volume of 17.6 ml3. You want to determine the Density of this cube.
Step 1 Density (g/ml3)=Mass(g)/Volume (ml3)
Step 2 D= ? M= 35.7g V= 17.6 ml3
Step 3 D= 35.7g/17.6ml3
Step 4 D=2.028g/ml3 rounded to 3 sig fig (significant figures) the answer is:
Step 5 D= 2.03g/ml3 Circled
Following this, students engaged in a practice lab where they measured cubes and then we began using the indirect method for determining the volume of an object that has an irregular shape. While this method works, it is less accurate. What are some of the sources of the inaccuracies?
All classes were reminded that they would have a test on Monday.
Brain bender:
Clara Kaufmann has the uncanny ability to be able to listen to the radio, carry on a conversation, or even watch TV while reading a book. One night Clara was watching TV while reading a book when suddenly the power went out. Her husband, unable to find any candles, decided to go to bed. However, Clara kept reading, even though the room was completely dark. How could she continue to read?

Weather and Atmosphere:
Unit Essential Question: How do the relationships among the five spheres affect life on Earth
How do the relationships among the five spheres affect life on Earth?
Key Learning Statement: The atmosphere is layered and within these layers are weather patterns that affect life and are caused by interactions among spheres. Water is constantly being recycled through the spheres. Heat transfer affects the development of weather.
