Science Class, 2nd. partial 2nd. assignment update letter. Oct. 24th - 28th, 2016.


7th Grade, assignements activity update.

My dear student of "Exploring living things" Science class, this week we'll be continuing with the cell activities, paying special attention to the following topics:

Ch. 5 Cell Processes
Section 5.1 Movement of Substances

In this section you'll be performing the lab practice: "Movements across membranes" so be ready to enjoy our 2nd lab exploring experience and relate its findings with the concepts that we'll be sharing in class time.
As a homework try to perform the "You can't make an Omelet..." activity, described in your tx-bk pag. 95. Remember to record every finding during this activity and write them down in the lab report format that we have discussed since the 1st. partial.

Here I share some an intersting video for you to understad better the concepts about Diffusion and Osmosis. After having watched the video, please answer the thinking critically questionnarie:

Movement of substances questionnarie:

1) What is Diffusion?

2) What is Osmosis?

3) What is the function of the cell wall in these movement processes?

4) What is the function of the cell membrane in these movement processes?

Define: High concentration

           Low Concentration

           Concentration gradient

           Turgid

           Flaccid

           Plasmolysis

5) Why did the animal cell burst out in the high water potential zone, in contrast with the plant cell that didn't suffer any change at all?

Section 5.2 Energy Processes.

In this section you'll be exploring how plants processes energy from the sun's light. I suggest you perform at home the "Leaves of Gas" activity, described in your tx-bk pag. 99 as well as the "Plants you eat" in pag. 100. Remember to record every step of the activity in a lab report format.

Well, that will be all for next week. Enjoy your weekend!

8th Grade, assignements activity update.

My dear student of "Earth Science" class, this week we'll be continuing with Ch. 5, Section 1 Earth Interior, paying special attention to the following topics:

Exploring Inside Earth
A Journey to the center of Earth
The Mantle and The Core

In this section you'll be performing the lab practice: "Princeple of Seismograph" so be ready to enjoy our 2nd lab exploring experience and relate its findings with the concepts that we'll be sharing in class time.
Try to resolve at home, the lab zone skills activity "Creating Data tables" described in your tx-bk pag. 129,  it will be finished up during our class time
As a homework you will be drawing in your notebook, a figure from your tx-bk pag. 129 it is figure 6 Lithosphere and Asthenosphere. You may use construction paper in different collors so you can make a nice copy of that image.

To get into the mood of this next week topics watch the suggested video so we can discuss some concepts during class time, I hope you enjoy it:

Well, that will be all for next week. Enjoy your weekend!

9th Grade, assignements activity update.

My dear student of "Physical Science" class, this week we'll be continuing with Ch. 4, Section 1 Ionic Bonds, paying special attention to the following topics:

Electron Transfer
Forming an Ionic Bond
Polyatomic Ions
Naming Ionic Compounds
Properties of Ionic Compounds

Here is a video so you can have a image of what is this topic about.

In this section you'll be performing the lab practice: "Shape up" so be ready to enjoy our 5th. lab exploring experience and relate its findings with the concepts that we'll be sharing in class time.
Try to resolve at home, the sharpen you skills activity "Interpreting Data" described in your tx-bk pag. 117,  it will be discussed during our class time.
As a homework you will be resolving the Discover activity described in your tx-bk pag. 114, and resolve the Think it over inquiry that accompany this activity, you may write your observations in your notebook and paste some images to illustrate your activity.

Remember to finish up the following assignments about the Periodic Table issue:

Discover activity "Which is easier" in your tx-bk pag 81, resolve the think it over inquiry.
and the Alien Periodic table as well described in the tx-bk pag. 104. Don forget to write down your observations, for this activity in particular, in a lab report format, presented at the begining of the year.
