§3.5 Along the axes
Before doing this § yourself,
let's watch a few fine points!

Slide 1 - Tekstslide

Explain the difference between 'axis' and 'axes'.

Slide 2 - Woordweb

Solution:
One axis, but two axes.
That's all.

Slide 3 - Tekstslide

WORDLIST (1):
Open your Notebook and Copy the following words in your wordlist:
axis, axes - as, assen                                                  
to weigh - wegen                                                          
(to grow) at a steady pace - constantly              
the scale - de schaal, bijv. 1 : 3000                                     
annually - yearly
to estimate - schatten                                                  


Slide 4 - Tekstslide

WORDLIST (2):
Open your Notebook and Copy the following words 1 t/m 6 in your wordlist:
1 axis, axes - as, assen                                                   javelin - speer
2. to weigh - wegen                                                          a candle is lit - een kaars wordt(!) aangestoken
3. (to grow) at a steady pace - constantly              skydiving - jumping out of a plane, not opening
4. the scale - de schaal, bijv. 1 : 3000                                     your parachute yet
5. annually - yearly
6. to estimate - schatten                                                 
7. to measure - meten

Slide 5 - Tekstslide

Points of attention:
+  See how SMOOTH 
this graph runs!
+  The ZIGZAG on the vertical
 axis! ( in this way 0 - 107 beats 
are pressed in 1 cm!)

Slide 6 - Tekstslide

No ZIGZAG ?!
No indeed, 
on the horizontal axis 
we don't use a zigzag.
Zigzags are only used on the vertical axis!
Don't ask me why...

Slide 7 - Tekstslide

Watch ...
The SCALES on the Horizontal axis 
and the vertical axis 
are not the same! 

Slide 8 - Tekstslide

Slide 9 - Tekstslide

Task  1:
When drawing a graph 
for this table, 
what SCALE is best, on the vertical axis,
so for the HEIGHT in metres?
  1 cm = ....... metres (fill in in next slide!)

Slide 10 - Tekstslide

1 cm = ......... metres

Slide 11 - Woordweb

solution:
The best scale on the vertical axis is: 
1 cm = 500 metres !
As 3800 metres is the highest height in the table,
you then need  3800 : 500 = 7.6 cm (say 8 or even 9) on the vertical axis.

Also 1 cm = 400 metres is good! Then the vertical axis is 3800 : 400 = 9.5 cm  

Slide 12 - Tekstslide

Task 2:
In the next slide,
describe the main advantage (voordeel) of 
plotting TWO graphs 
in ONE coordinate system. 
Use only ONE WORD! It's a VERB (=werkwoord).
(You now can ........... ?!)

Slide 13 - Tekstslide

You now can .........!

Slide 14 - Woordweb

Slide 15 - Tekstslide

Slide 16 - Tekstslide

Homework time

Correct with the Solutionsbook
Make pics and
Send them in in Google Classroom. 
I hope you have the same amount of fun as the man next slide!
