Math Transformations

Body Systems

Explorers!
Below are links for the body systems we'll be investigating over the next two days. Remember, your top priority is to research the function of your assigned body system, as well as the specific functions of the organs of your body system.

Circulatory System

Digestive System

Respiratory System

Muscular System

Nervous System

Skeletal സിസ്റ്റം

Urinary System

Skin

Take care,
VKV

I Heart EE Explorers!

Explorers,
Please look up the following link on the circulatory system, also known as the cardiovascular system.

Physical and Chemical Changes

Apple

1. What is the atomic number and atomic symbol of Oxygen? What is the atomic number and symbol of Iron (This one is a little trickier. Study the periodic table closely.)?
   

   
    

2. Look up the apple link on the website. Why do cut apples turn brown?
   

   
    

3. What other chemical reaction, which occurs on bikes and gates, is similar to what happened to the apple?
   

   
    

Eggshell

1. Please click on the eggshell link. What is eggshell made of?
   

   
    

2. Look at the chemical formula on the webpage. What is produced when the eggshell combines with the acetic acid (vinegar)?
   

   
    

3. Soda also has acetic acid. Hypothesize, why do dentists worry about people drinking too much soda?
   

   
    

   
    

Hand Warmer

1. Please read the 2 paragraphs in this advertisement. What is inside the warmer pouch, or bag?
   

   
    

2. What causes the bag to warm up? In addition to heat, what is produced when the bag warms up?
   

   
    

   
    

   
    

   
    

Ice

1. Please draw and describe the atoms of a solid, as shown under the microscope on the website.
   
2. Draw the differences between atoms of solids, liquids, and gases.

Finally, please watch this slide show that depicts examples of pollution in China.

Acid Rain Investigation

Dear MST-7 Scientists,
Please read this article to read about how pollution in China can affect the United States.
http://www.cnn.com/2007/WORLD/asiapcf/11/13/pip.coal.ap/index.html?section=cnn_latest

Second, this week we will investigate how we can reduce the volume of acid rain that enters our soil.

Today’s objective will be to define acid rain and figure out how it’s produced. You will answer the following questions:
· What is acid rain?
· What chemicals make rain acidic, and how does it happen?
· Can you find a chemical equation that shows how acid rain is created?
· Where do these chemicals come from?

Good luck scientists!

Periodicity

Periodic Table - What is a group? What is a period?
Families - How are elements grouped into families?
Metals - What % of elements do these make up?
Lanthanide Series (part of the inner transition metals) - Under "Meet the Family", what is unique about the actinide series?
Halogens - How many electrons do halogens have in their valence energy levels? What do halogens like to react with?
Inert gases (noble gases) - Why are they happy?
