9+Science

Welcome to 9th Grade Science!

My email address: misskellie@lapazschool.org

June 27



June 15-16: 9th Monday and Tuesday: They turned in their second rough drafts on Friday. They should work on setting up their experiments to test solubility. They can use the guide attached below. This is a guide for a single experiment. Since they will be testing multiple things, they will have to think through the process of identifying variables and testing a hypothesis more than once. On Wednesday and Friday, they will be testing their hypotheses, so if they need any extra materials outside of what we have in the science classroom, they should be sure to bring them. Please remind them.

 * https://www.youtube.com/watch?v=mozGbPNFf8c
 * https://www.youtube.com/watch?v=iDH-RiDxqE4


 * What is a multimeter and what is its function?

Agenda: Warmup/discuss Homework check How to use a multimeter

**Review** • **A meter capable of checking for voltage, current, and** • **When measuring Voltage the multimeter must be connected to** **two points in a circuit in order to obtain a good reading. Be careful not to touch the bare probe tips together while measuring voltage, as this will create a short-circuit!** • **Never read Resistance or test for Continuity with a multimeter on a circuit that is energized.** • **When measuring Current the multimeter must be connected in a circuit so the electrons have to flow //through// the meter** • **Multimeters have practically no resistance between their leads.** **This is intended to allow electrons to flow through the meter** **with the least possible difficulty. If this were not the case, the meter would add extra resistance in the circuit, thereby affecting the current**
 * resistance is called a //multimeter//,**

** Topic: Properties of the Ocean ** ** Theme: Change ** Is the ocean becoming saltier? If so, is that a problem? Dr. N. A. Seeal, a visiting research scientist on our ship, wants to know the answer to this and other perplexing questions about the ocean's salinity. He is enlisting the help of our ship and crew.
 * Problem: **

Dr. N. A. Seeal says we must first find answers to the following questions: ** Mission: **
 * 1) Why is the Ocean salty? (Conrad)
 * 2) Where does the salt come from? Explain. (Ariel)
 * 3) Is all ocean water salty? Explain. (Rony)
 * 4) Which ocean/s is/are the saltiest? Explain. (Denis*)
 * 5) What affects how salty the ocean is? Explain. (Josue and Cloe--separately)
 * 6) Is the ocean becoming saltier? Why or why not? (Zelenia)
 * 7) Where would each ocean be least (and most) salty? Explain.(Swan)

__ Part I: __ Create a visual presentation of your findings! (i.e. pie charts illustrating the chemical composition of the ocean or oceans, line graphs of the three major oceans showing seasonal salinity readings or a comparison of the salinity of each of the oceans to one another) After all, Earth really has only one ocean. Oceanographers have broken it down into three major divisions: Atlantic, Pacific, and Indian. Why have they done this? What purpose does this division serve? (Some sources of information refer to four oceans. Oceanographers, however, consider there to be only three.)

Here are some sites that might help you: > http://www.nodc.noaa.gov/General/salinity.html
 * NOAA National oceanographic Data Center (NODC)

**Note: You can produce your graphs using programs such as EXCEL or you may create them using graph paper, rulers, protractors, and compasses.**

Assessment (Part 1): ** You and your team will be assessed on the accuracy and clarity of your answers to Part I of your mission, as well as on the quality of your presentation to the class and visual aide.

HOMEWORK: 1) DECIDE WHAT GRAPHS AND IMAGES YOU WILL USE ON YOUR VISUAL AIDE, AND I'LL CHECK IN WITH YOU ABOUT IT TOMORROW DURING CLASS

 * First Response: **

Hi Kellie,

Thank you for your email. I'm sorry I missed your call earlier, but even if we spoke I would not have been able to answer your question about astronomy/astrophysics.

I am sending your inquiry to my colleagues in the NASA Science Mission Directorate. Hopefully they can identify a NASA scientist who can help answer your query about determining the age of stars.

Thank you for helping to inspire the next generation of scientists!

Have a nice weekend,

Ann Marie
