The Nervous System

Here are the notes for the Nervous System! Remember we have a test on this and the digestive system on Wednesday the 19th!

------------------------------------------

The Nervous System - The system of nerve cells and fibers that send signals between parts of the body.

Brain

• This is where all information is processed and responses are formed. Basically, the brain gets an email then writes and sends a reply.

The Spinal Column

• This is where the central nerves are located.

Peripheral Nerves

• These are what get the information from the world around us and send them to the brain as nerve impulses. The brain will then send back a response for the nerves to share with the muscles in order to make them move.

Within the nervous system there is the autonomic system. This is various organ systems that function without you having to think about it.

Examples of this are your heart beating and breathing. You don't have to think "breath in" and "breath out" in order for it to happen.

Have a wonderful weekend!!

Quick Reminder

Just wanted to post a quick reminder about the Unknown Numbers test that we are having tomorrow. 

We will be starting the Nervous System tomorrow, and the notes will be posted for those as well. There will be a test on the Digestive and Nervous systems on Wednesday the 19th. 

Have a wonderful afternoon and thanks for visiting! If you have any questions, comments, or concerns feel free to send an email or leave a friendly comment below! 

Fact Families

Today we touched on Fact families which will be discussed in more depth next week. Fact families are wonderful for showing how multiplication and division are related. They are simply all of the possible division and multiplication equations that are possible with a specific set of numbers.

For example: The fact family for the numbers 7, 3, and 21 is: 3×7=21   7×3=21   21÷7=3   21÷3=7

We have already gone over changing to the inverse (or opposite) problem many times, so the students know how to go from multiplication to division and vice versa.

The purpose of this is to show how multiplication and division are related which also helps them to identify and solve for unknown numbers.

Digestive System

Digestive System

Today we started our unit on organ systems. We are starting with the digestive system and will be talking about it for a few days. They will have a short test on this and the nervous system next week.  

The digestive system notes are as follows, and only the highlighted portions have/had to be written:
---------------------------------------

Organ System- multiple organs working together to perform a particular task or set of tasks

Digestive System- the organ system that is used to break down food into energy

There are many parts to the digestive system, but we are going to focus on the five main ones.

A. Mouth   B. Esophagus   C. Stomach   D. Large Intestine   E. Small Intestine

Mouth- this is where food is first introduced to the digestive system and saliva (spit) begins to break down the food as it is chewed.

Esophagus- also called the throat; muscles push food down the esophagus to the stomach

Stomach- muscles cause the walls of the stomach to move and further mash up the food while digestive juices break the food down as much as it can

Small Intestine- food travels through this tube that is 20 feet long, and continues to be broken down into smaller and smaller pieces. Then it is stopped and all the nutrients are absorbed and sent into the body

Large Intestine- finally food is moved into the five foot long tube where most remaining water is removed from the food; once it reaches the end of the tube, the food is expelled from the body as waste

The digestive system takes care of all of the food and drinks that we consume, and makes sure that we get all the good nutrients from the food.

These nutrients are what give us the energy to do fun things and keep us healthy, so it is important to take care of our digestive system!

Drinking plenty of water and eating healthy are just a couple of ways that we can help our digestive system do its job!

Unknown Numbers

Unknown Numbers

Today we went began going over unknown numbers once again and in more detail.

An unknown number is like(21÷n=3) (5 x H=10) (R÷8=2) (9x6=k)

We are teaching them to know whether or not they need to multiply or divide by looking at what numbers they have.

If they have the dividend(the 21 in the example above) or the product (the 10 in the above example), then they have to divide. (21÷3=n) (10÷5=H)

If they have divisor (the 8) and the quotient (the 2), or both factors (the 9 and 6) then they would multiply to find the answer. (8x2=R) (9x6=k)

On my each of my walls I have added two artifacts for them to look out throughout the lesson. These look like the following:

Dividend--->Divisor/Quotient--->Divide

Factor--->Product--->Divide

Divisor--->Quotient--->Multiply

Factor--->Factor-->Multiply

And:




21 ÷    3 =   7
^                  ^            ^
Dividend           Divisor       Quotient

3 x   7 = 21

^            ^          ^

Factor         Factor      Product
