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)
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.
