Food Tests

Food Tests:

Test	Tests for	Positive Result	Method
Iodine	Starch	Turns Blue-Black	Add a drop of iodine to food solution
Biuret (CuSO4 + NaOH)	Protein	Turns Purple-Lavender	Add a few drops of copper sulphate (CuSO4) shake and wait, then and sodium hydroxide (NaOH) to food solution
Benedict’s Solution	Sugar	With heat turns Brick-Red precipitate	Add a few drops of Benedict’s to food solution and heat gently of a bunsen
Ethanol Emulsion	Fats	White Emulsion	Add 2ml of ethanol to food solution and shake/mix, then add 2ml of water to solution and shake/mix
DCPIP	Vitamin C	Turns Colourless	Add a few drops of DCPIP to food solution and shake/mix then wait (NB: will turn pinky due to the presence of acid - false positive)

Trebuchet

Velocity - Distance - Time

Speed (Velocity) is a change in distance per unit time. SI unit: meters per second (m/s or (ms-1)
Distance is a length. SI unit: meters (m)
Time is needed for things to change. SI unit: second (s)

Using the S,D,T Triangle

Distance Time Graphs

Acceleration - Velocity - Time

Acceleration is a change of speed (velocity) per unit time. SI unit: meters per second per second or meters per second squared (ms-2)
Speed (Velocity) is a change in distance per unit time. SI unit: meters per second (m/s or ms-1)
Time is needed for things to change. SI unit: second (s)

Plans for making a Trebuchet & Catapult

Designing a Trebuchet – Optimizing Weight and Length

Cam's Trebuchet

Optimisation of Trebuchet:

The length of the payload arm should be 3.75 times longer than the counterweight arm.
The length of the sling should be the same length as thepayload arm.
The initial angle between the counterweight arm and the support should be 45 degrees at launch.
The counterweight needs to be 133 times as heavy as your intended projectile.
