Natural Science test

You have your Natural Science test on Unit 3: Reproduction on Friday, 5th May.

We will correct the review sheet in class on Thursday (6ºB-- we will do Natural Science instead of Social Science on Thursday.)

You must study:

--The diagrams of the male and female reproductive systems (label and explain what each part does.)
--The chart on page 40 about the different life stages
--The two types of sexual characteristics (primary and secondary) and when they appear
--The menstrual cycle
--Puberty changes in girls and boys
--Genes: what they are and why they are important
--Pregnancy and birth
--Gender equality (p. 49)

Good luck!

And remember:

The Female Reproductive System

We are learning about the female reproductive system.

The heart

Since it is Valentine's Day, we can study the structure of the heart!

 Also: composition of the blood.

The blood circulation system.

Do you know what is in our blood?

Watch to find out!

How about this one?



Here's a song!


The Bloodmobile
The Bloodmobile
A delivery service inside us

We begin in the heart's right ventricle
And travel to the lungs
Red blood cells get oxygen
To take back to the heart
Then from the left side of the heart
And out to every cell
Delivered by the Bloodmobile

The food that's been digested
Is waiting at the dock
To be taken to the tissues
In the body's grocery truck
So from the small intestine
It's carried everywhere
Delivered by the Bloodmobile

The Bloodmobile
The Bloodmobile
A delivery service inside us

The white blood cells are soldiers
That fight infectious germs
They make the antibodies
Their weapons in the fight
The army is transported
Wherever they must go
Delivered by the Bloodmobile

We need to send a message
To tell a limb to grow
Or speed the heart or regulate
Your hunger or your sleep
The hormones are the message
They're sent from many glands
The messenger's the Bloodmobile

Somebody's got to haul out the trash
To the liver and the kidneys
It's not a pretty job
Carbon dioxide gets carried
To the lungs to be exhaled
And the garbage truck is the Bloodmobile

The Bloodmobile
The Bloodmobile
A delivery service inside us
To carry oxygen, nutrients, things that fight infections
Do the trash collection and deliver the mail
And we're all (and we're all)
Delivered by the Bloodmobile

The digestive system

Learn about the process of digestion.

What about muscles?

How your nose and tongue work

How do we see? How do we hear? How does our skin work? How does our brain work?

Why do we....

In Natural Science, we are studying about the Nervous System. The brain is such a fascinating organ!  Some questions came up in class:

Why do we yawn? 



Here's an explanation from KidsHealth

But there have been new studies that suggest that yawning helps us cool down our brains and think more clearly.  Read this article for more information! 

Giving a response

We are learning about body systems in Natural Science. First we are going to study how we receive information, process information, and give a response.

Here is a nice summary of the process.

Here is a game about the Nervous System.
