Q-Question	Does our body have ideal proportions in the classroom?
P-Participants	Year 11 students-(10 students)
V-Variable	Height-(Explanatory Wingspan-(Response)
R-Relationship	What are we going to expect? We are going to measure their arm-span correctly to see if it is the same as their height.

S-Step by step	1.The participants remove their shoes 2.Make sure the students are up straight 3.Use the tape measure, measure their height from their feet to the top of their head. 4.Use something flat like a book on top of their head just in case of false reading. 5.put data onto a book or spreadsheet. 6.Measure all the participants.
C-Control factors	Avoiding mistakes,trying to control them like false readings.
C-Conditions	-
R-Repeat	Repeating the same measurements to see if you get the same results.

Problem:

Does our body have ideal proportions in the classroom?

Plan:

Two variables:

1-Wingspan (Response)

2-height (Explanatory 

Our plan is to Measure the wingspan of 10 students in the classroom, and compare wingspan to height.Before we start we going to remove shoes just in case of false reading and we are going to make sure the participants arm is straight, not angled and make sure that there body is up straight for the wingspan.

Participants:10 students

Relationship-We are going to see if the measurements of wingspan has similarities to the height of the participant. 

Errors that will need to be avoided:

-Shoes are going to have to be removed because of the inaccuracy of the measurement

-baggy clothing also will have to be removed

-Hair is going to be let down 

-keeping the body posture straight

-have your arms straight when measuring wingspan

-have your body and head up straight when measuring height

Data:

I will need to capture the data from the measurement.So capture the height in meters and wingspan in metres also.We are going to use the rules from the plan to capture the data accurately to get an accurate measurement.

Virtruvian Man

 who is vitruvian man?

The Vitruvian Man is a drawing made by the Italian polymath Leonardo da Vinci in about 1490. It is accompanied by notes based on the work of the Roman architect Vitruvius.

Who is leonardo da vinci?

Leonardo da Vinci was an Italian polymath of the High Renaissance who was active as a painter, draughtsman, engineer, scientist, theorist, sculptor and architect.

Different types of graphs

What are graphs and what are they used for?Graphs and charts are visuals that show relationships between data and are intended to display the data in a way that is easy to understand and remember. People often use graphs and charts to demonstrate trends, patterns and relationships between sets of data.

Here are some example's of different kinds of graphs and charts such as Pie graphs,bar graphs,line graphs and donut chart.

1.what is a Pie graph and what is it in use for?

Pie charts can be used to show percentages of a whole, and represents percentages at a set point in time. Unlike bar graphs and line graphs,pie charts do not show changes over time.

2.What is a bar graph and what is it used for?

Bar graphs are used to compare things between different groups or to track changes over time.A bar chart is a graph with rectangular bars. The graph usually compares different categories.

3.what is a line graph and what is it used for?

Line graphs are used to track changes over short and long periods of time. When smaller changes exist, line graphs are better to use than bar graphs. 

4.What is a Donuts chart and what is it used for?

Donut charts are used to show the proportions of categorical data, with the size of each piece representing the proportion of each category.

Circle and terminalogy

 How I do calculate the circumference of a circle?

Formule based= using radius

                            circumference = 2𝛑r

                            Using diameter= 

Radius = 26000mm

Diameter = 520000

PI = 22/7 or 3.141

To convert the radius from cm to M I am going to divide it by 100

26000/100 = 260 m

Cir 2 x PI x 260

=1633.62817987

Area of 3 basic shapes

Area 

The area can be defined as the space occupied by a flat shape or the surface of an object

Triangle:

Rectangle:

Circle:

Square:

Volume of a Rectangle

 How to work out Volume

1.What do we mean by Volume?

Volume is the amount of space inside of an object so like a 3d shape if we want to measure the volume of a square we need to measure how much is inside of it.

2.How do we measure Volume?

 To find the volume, you multiply length times width times height to get the total volume inside of the 3d Object.

3.How to find the area of a circle?

The area of a circle is pi times the radius squared (A = π r²).

Can we convert Volume into Litres?

The volume in liters is equal to the cubic inches multiplied and What I got from the internet is you Multiply by 0.016387.Cubic inches and liters are both units used to measure volume.

What is the Volume of the Pool?

Length=8m

width=3m

Height=1.2m

-Working=3x8x1.2=28.8

28.8x1000=28800mL
