KS3 C2.1 - PHYSICAL PROPERTIES

Mercury Pouring in Slow Motion.mp4

Practical

Observations of physical properties:

  • Lump of copper
  • Test tube with something thick (eg golden syrup)
  • Loadstone or magnetite with paper clips
  • premade slime
  • and other materials to test colour, ductility, odor, density, hardness, viscosity, luster and conductivity

Risk :

  • Luminous bottle do not drink

KS3 C2.2 - OXIDATION

Practical

Oxidation practical (all done on a balance)

Students burn the following to see if it causing a oxidation reaction, noting the before and after weight:

  • 11x Magnesium
  • 11x Steel Wool
  • 11x Zinc
  • 11x Sulphur (matches)
  • 11x Iron
  • 11x tongs

Practical

Students test the different compounds in a test tube and test for Hydrogen

Squeaky Pop test:

  • 11 x Test tubes
  • 11x magnesium, zinc, copper, aluminium iron wool.
  • 11 x Acid
  • 11 x pipettes
  • 11 x small beaker to hold acid
  • Splits

Lesson Guide

Practical

Acid and Alkali experiment.


- Sample Trays

- 3 x Various house hold alkali substances. e.g hand lotion, bleach, soap.

- 3x Various house hold acid substances. e.g coke, vinegar, lemon.

- 3 x Various house hold neutral substances e.g bottle water, toothpaste.

- ph paper and Ph scales


Students are expected to collect small samples of the various house hold substances. they can use PH paper to find the PH and record the results using an indicator

Risk


Students should wear goggles

sinks should be free and open in case of spillage/washing

KS3 C2.7 - Determining PH

  1. Lesson Guide

Practical

Determining PH Experiment


to distribute :

1 x Jar of water (A)

1 x jar of acid (B)

1 x jar of alkali (C)

1 x jar of weak acid (D)

1 x jar of weak alkali (E)


11x

1 x Indicator bottle

5 x test tubes

5 x pipettes


Students are determining the Ph of the mystery liquids labelled A,B,C, D and E. They are being trained to use PH indicator in small amounts, and learn about contaminating their pipettes if they are not too careful.


Risk


Students should wear goggles

sinks should be free and open in case of spillage/washing

KS3 C2.8 - Neutralisation

zUxyQobbfPrqy_ya.mp4

Practical

Balancing the Ph

For distrubution:

  • An Acid
  • An Alkali
  • Indicator

11x

1 x Test tubes

2x boiling tubes

2x pippettes


Students drop some indicator into their test tube. They will then fill up their boiling tubes with an acid, and alkali, and a pipette in each.

The studnets will then try and balance alkali and acid in the test tube to make it competely neutral.

Risk


Students should wear goggles

sinks should be free and open in case of spillage/washing

KS3 C2.9 - CorePractical

Practical

Investigation into indigestion tablets

For distrubution:

  • An Acid (I will lie and say it is real stomach acid
  • Indicator
  • 2 x balance


11x

3 x indigestion tablets (differing brands)

3 x small beakers

1 x Pestle and mortar

3 x boiling tubes

1x small measuring cylinder


Students investigate three types of tablets. Emphasis on being fair in an experiment. Instruct them how to use a balance and what zeroing is. Tablets are crushed, added to a small beaker. The same mass of tablet is added to each test tube where the same amount of acid is added. Indicator is then dropped in.

Risk


Students should wear goggles

sinks should be free and open in case of spillage/washing
