(Finish NB#59 & 60 when we return from Thanksgiving.)

WEEK 13 (November 7 - 9, Tuesday & Thursday)

TUESDAY, 11/7

1. Review Quiz Density. If you are still having problems solving density problems, watch the the video embedded below Thursday. Maybe this technique will help you understand ways to solve mass, volume, density calculations.

2. Finish NB#54 Propellant Acetic Acid and Sodium Bicarbonate

• Last week the IV was the amount of acetic acid. You will complete that testing and then make the sodium bicarbonate the IV (on NB#55). You will decide on the volume of vinegar to keep constant.
  • 1. Based on your results, determine the best mixture ratio for the propellant of this inquiry. Give support (refer to your data) for your selection.
  • 2. Describe what factors play a role in making this ratio of acetic acid to sodium bicarbonate the best mixture ratio for propelling the plastic canister rocket. Think also what factors play a role in altering the height a rocket should rise.
    • EXTRA: If you have time in class, repeat the best mixture ratio with the aims of determining the mass of baking soda that does and does not react during the flight of the rocket.
• HOMEWORK: Finish NB#54/55. If you are not done collecting data, answer the the questions based on the results you do have. Make reference to what you have not tested in your response.
• Next week, you will learn how to determine the amount and mass of carbon dioxide produced with a given gram of one of the reactants.

THURSDAY, 11/9

• NO SCHOOL

WEEK 10 (OCTOBER 16 - 20, Monday, Wednesday, & Friday)

MONDAY

School closed due to Tubbs Fire & advisory evacuation

WEDNESDAY, 10/18

1. CHALLENGE:
   • Determine the density of water in g/ml.
     • PART 1: With your lab groups, discuss a procedure, collect the data, compute the answer. Record your progress on your group whiteboard. Include the temperature of the water. Share your results with the class.
     • Transfer your findings to your Notebook, #40 Challenge: The Density of Water. Record in a meaningful way, so the purpose, results, calculations, and analysis makes sense to a reader.
     • PART 2: Collect enough mass and volume values for water to create a line graph of your results. (Three to five collections, depending on how quickly your lab group works)
       • Volume on x-axis
       • Mass on y-axis
       • A line of best fit
       • Calculate the slope
       • State the meaning of the slope with units and a brief description
       • What is the meaning of the slope?
       • How does the density compare to Part 1 and the discussion

2. NB#41 Water Density Versus Temperature Graphs

FRIDAY, 10/20

1. NB#42 SPECIFIC GRAVITY....Notes...What is it and why learn?
   • See the video called Specific Gravity embedded below Week #9
   • Watch and then take notes on the movie
2. NB#43 Challenge: Find the Specific Gravity
   • Goals
     1. Find the s.g. of an object
     2. Determine the percent that will be submerged in water
     3. Draw the object in water (correctly submerged)
     4. SUMMARY: First, we found the density of our object by dividing its mass by its volume. (We used the scale for mass and the water displacement method with a graduated cylinder for volume.) Second, we calculated the specific gravity of the object by dividing its density by the density of water. We multiplied its s.g. by 100% to determine the percent submerged in water.

2. NB#44 Density, Elements, & the Periodic Table (Comparing Densities Across Periods of the PT)

• Color code atomic number by periods

NEXT WEEK

1. Density Trends of the PT
2. Upstream Mary Oliver... excerpt & discussion.
   • HOMEWORK Upstream (Due Thursday)
     • Density in life (natural or human made) description (not copied, list source)
     • Present this density in an original form (Oliver style "essay" excerpt", poem, drawing, etc)
       • This assignment won't take too long and does not require extensive research (information from one web site will do). It is expected you are neat. Content and presentation matter. It is suggested you follow these steps:
         • Search for density in life topic (natural or human made)
         • Read and learn
         • Write a description (in your words); include the source.
         • Think how you can present the facts in a creative and original way
         • Do that creative interpretation

2. Learn the purpose and function of dimensional analysis... a helpful tool to enable you to use units to solve mathematical problems. Hard problems become easy once you understand how to use units to help you decide which numbers to multiply and divide to get the answer you are looking for!! See the video embedded below Specific Gravity, for a video on the topic
