Landforms ------ Lesson 1

Focus Question: How are mountains important to people’s lives and how do human activities affect mountain environments?




Content Summary

Landforms are natural features of the Earth. There are different formations on the earth which occur naturally. Some areas are high while others are low. These natural features may be seen on a special type of map known as a relief or physical map. How high the land is above the level of the sea determines the type of landform that is present. Landforms include:


 Mountain:   highlands that rise more than 500 metres above sea level

 Hills:  highland areas that rise between 100 – 499 metres

 Valley:  lowland between two highlands

 Plain:  large areas of flatlands  (Chielfly located on the southern sides of island in Jamaica

 Plateau:    Flat area at the top of a mountain  (flat top mountain)

Examine the diagrams below.

The Skeleton

The skeleton is the bony framework of the body. It consists of approximately 206 bones.

The diagram below represents the human skeleton.





The skeleton has a number of functions.
1. It supports the body
2. It gives the body shape
3. It protects vital organs of the body eg. heart, lungs, brain.
4. It causes movement of locomotion.

Watch this video clip to learn more about the skeleton.

Complete the little quiz at the bottom of the video clip.

Evaluation:
1. Complete the quiz here,.

2. Label the skeleton in this link.

3.  Name the part of the skeleton that protects the following organs:
   (a) the brain
   (b) the heart

4. Your friend, Rob does not believe that the skeleton is all that important. What are your views about Rob's belief?______________________________________________________________________

Provide some points below to share with Rob so he can change his belief.

5. The skeleton is sometimes labelled with the scientific names for some bones.
some examples are:
clavicle - collar bone
sternum- breast bone
patella - knee cap
cranium- skull
femur- leg bone

Now on the diagram below, try to label using both names where applicable.



6. Where in the body can you find the:
(a) the largest bone? _________________________
(b) the smallest bone? ________________________

Reflection

Topic: The Cartesian Plane - Reflection

Focus Question: How do I use the Cartesian Plane?

Content: This refers to a transformation that involves a flipping movement of a figure over a line.

Obj.: Perform reflection of a shape or design in a horizontal or vertical line in the first quadrant of the Cartesian Plane.

Engage: Students you would have remembered the following terms from the previous lesson on plotting coordinate points and reading coordinates points. Define the following.

* quadrants
*x-axis
*y-axis
*coordinate points
*point of origin
*ordered pair

Explore: Today we will be looking at reflection.
This refers to a flipping movement of a figure over a line.
Examine the video clip to glean information on reflection.

Explain : Can you now explain what you have learnt from the clip?
You would have learnt that:
(a) the shape was reflected about the mirror line
(b) the position of the shape has changed
(c) each point of the reflected image is the same distance from the mirror line as corresponding point of the  first shape
(d) the shape and size of the shape has not changed.

Extend: You may watch the other video clip below to glean additional information for note taking.

The Cartesian Plane

Focus Question: How do I use the Cartesian plane?


Content Summary`

A coordinate plane contains a horizontal number line called the x-axis and a vertical number line called the y-axis. The point where the two axes cross/intersect is called the origin. The number pair (0,0) gives the coordinates of the origin.

To read or plot a point, we use an ordered pair made up of its x-coordinate and y-coordinate. These coordinates measure the distance from the origin.
Examine the link below for additional information.


Specific Obj: By the end of the lesson, students should be able to:

1.      

          1. Explore how a coordinate system identifies location and use the first quadrant of the Cartesian plane to plot points.

ENGAGE:


Students you will recall that the number line was done in previous grades. What do you remember about the number line?

Ok let's see what it looks like again.


EXPLORE:

Now to plot coordinate points, we use two number lines as shown below.

Now watch this video clip to see how we can plot points. Be sure to take your notes.

EXPLAIN

Now can you explain all you have learnt.

EVALUATE:

1. Using the diagram below, write the coordinate points of each place.
