Pikelets on Friday, 29 Aug. Period 4 in V5

You will need the ingredients below plus fillings per group. Mrs Nathan will bring the ingredients, including milk, surviettes and eggs but groups will be required to bring self-raising flour, sugar, butter (100g max) to cook and other fillings. Also one measuring cup per group (I will bring my one just in case).

We also need plates, plastic knives and forks.
Groups of 5 (4 groups in total)
TARA: Jessica G, Cassie, Caitlin, Emma, Abbey
MELE: Karleen, Jessica L, Amber, Venezia, Ellen, Mercede
MANYA: Dana, Nicole L, Pascalle, Jenny, Leesha
SADAF: Rebecca, Charmaine, Khadija, Veronica, Hineari

Pikelet Recipe:

  • 1 cup (150g) self-raising flour
  • 1 tablespoon caster sugar
  • 3/4 cup (185ml) milk
  • 1 egg
  • Melted butter, to brush, plus extra knobs to serve

  1. Sift flour and sugar together into a bowl with a pinch of salt.
  2. Step 2Whisk milk and egg together, then add to dry ingredients, whisking until smooth.
  3. Step 3Heat a non-stick frypan over medium heat and brush with a little melted butter. Drop level tablespoonfuls of the mixture into the pan and cook for half a minute or until bubbles appear on the surface.
  4. Step 4Turn over and cook other side for 1 minute until golden.
  5. Step 5Allow to cool and serve with butter.

You need to be able to find the Perimeter and Area of a rectangle/square, Area of a parallelogram, Area of a triangle, Circumference (perimeter of a circle), Area of a circle, Vol.
Perimeter
To find the perimeter of a shape you have to measure the line around the outside of the shape. eg if you have a square with four sides the length of 5cm you would have to add the numbers up. 5+5+5+5=2
BY EMMA ADAM
Area of a rectangle
There is more than one way to the find the area of a rectangle. One way is to multiply the width by the length.

The distance around a two-dimensional shape.

Example: the perimeter of this rectangle is 3+7+3+7 = 20

The perimeter of a circle is called the circumference

Area = ½ × b × h
b = base
h = vertical height

Square
Area = a2
a = length of side

Example: What is the area of this rectangle?

Area Count

The formula is:
Area = w × h


w = width

h = height
We know w = 5 and h = 3, so:

Area = 5 × 3 = 15


Example: What is the area of this triangle?

Triangle
Triangle

Height = h = 12
Base = b = 20

Area = ½ × b × h = ½ × 20 × 12 = 120
A harder example:

Example: Sam cuts grass at $0.10 per square meter

How much does Sam earn cutting this area:

external image area-grass.gif
Let's break the area into two parts:
external image area-grass2.gif
Part A is a square:
Area of A = a2 = 20m × 20m = 400m2
Part B is a triangle. Viewed sideways it has a base of 20m and a height of 14m.
Area of B = ½b × h = ½ × 20m × 14m = 140m2
So the total area is:
Area = Area of A + Area of B = 400m2 + 140m2 = 540m2
Sam earns $0.10 per square meter
Sam earns = $0.10 × 540m2 = $54


Volume of a Cuboid

A cuboid is a 3 dimensional shape.

So to work out the volume we need to know 3 measurements.



external image cuboid.gif

Look at this shape.
There are 3 different measurements:
Length, Width, Height
The volume is found using the formula:
Volume = Length × Width × Height
Which is usually shortened to:
V = l × w × h
Or more simply:
V = lwh

In Any Order

It doesn't really matter which one is length, width or height, so long as you multiply all three together.

Example: Lengths in meters (m):

external image cuboid-example.gif

The volume is:
10 m × 5 m × 4 m = 200 m3
It also works out the same like this:
4 m × 5 m × 10 m = 200 m3

Note: the result is in m3 (cubic meters) because we have multiplied meters together three times.


Time - AM/PM vs 24 Hour Clock

Normally the time is shown as Hours:Minutes
There are 24 Hours in a Day and 60 Minutes in each Hour.


Example: 10:25 means 10 Hours and 25 Minutes

Showing the Time

There are two main ways to show the time: "24 Hour Clock" or "AM/PM":
24 Hour Clock: the time is shown as how many hours and minutes since midnight.AM/PM (or "12 Hour Clock"): the day is split into:
  • the 12 Hours running from Midnight to Noon (the AM hours), and
  • the other 12 Hours running from Noon to Midnight (the PM hours).

Like this (24-hour above and AM/PM below it):
external image day-am-pm.gif


AM
PM

Ante Meridiem*
Latin for "before midday"
Post Meridiem*
Latin for "after midday"
When:
Midnight to Noon
Noon to Midnight
24 Hour Clock:
0:00 to 11:59
12:00 to 23:59


*Is that spelled "Meridiem" or "Meridian"? See here.

Converting AM/PM to 24 Hour Clock

For the first hour of the day (12 Midnight to 12:59 AM), subtract 12 Hours
Examples: 12 Midnight = 0:00, 12:35 AM = 0:35
From 1:00 AM to 12:59 PM, no change
Examples: 11:20 AM = 11:20, 12:30 PM = 12:30
From 1:00 PM to 11:59 PM, add 12 Hours
Examples: 4:45 PM = 16:45, 11:50 PM = 23:50

Converting 24 Hour Clock to AM/PM

For the first hour of the day (0:00 to 0:59), add 12 Hours, make it "AM"
Examples: 0:10 = 12:10 AM, 0:40 = 12:40 AM
From 1:00 to 11:59, just make it "AM"
Examples: 1:15 = 1:15 AM, 11:25 = 11:25 AM
From 12:00 to 12:59, just make it "PM"
Examples: 12:10 = 12:10 PM, 12:55 = 12:55 PM
From 13:00 to 23:59, subtract 12 Hours, make it "PM"
Examples: 14:55 = 2:55 PM, 23:30 = 11:30 PM


HOLIDAY HOMEWORK - INVESTIGATE MEASUREMENT (use youtube, google, our wiki - under measurement etc.)


1. What equipment can be used to measure with?
2. Perimeter, Area and Volume - What are they?
3. 24 hour time, analogue clocks: Can you read an analogue clock? Can you tell 24 hour time?
4. Find examples of Timetables and maps (Eg: bus or train timetable)
