My 3d model by Mohsin Khan

My 3-D Project


My story is set in Lego Jedi’s castle.

I have created a 3-D model to represent my story setting.

I used polystyrene, cardboard, paint and crystals to produce my project.       .

Polystyrene is normally used for packaging and insulating; it is a synthetic thermal plastic material.                                                                                          

Cardboard is normally used for boxes and signs; it’s a stiff thin board made from paper pulp.

I created the crystal by conducting the following two experiments.

My Experiment : Create  Crystals

You will need :

  • Table Salt
  • Epsom Salt
  • Water
  • 2  Glass Beakers
  • 4 Petri Dishes


  1. Half fill two beakers with warm water.
  2. Add four teaspoons of table salt to one beaker.
  3. Add four teaspoons of Epsom Salt to the other beaker.
  4. Stir the water so that the salt dissolves.
  5. Add a few drops of food colouring for fun.
  6. Pour a little table salt solution into two petri dishes.
  7. Leave one petri dish in the fridge; examine the crystals after an hour.

            (It might take more than three days for the crystals to form.)

  1. Put the other petri dish in the oven for 15 minutes at 150′ C.
  2. Repeat the process for the Epsom salt solution.


Table salts crystals look like cubes; they are called cubic crystals. They have straight edges and flat faces.

Epsom salt crystals are needle shaped, however like cubic crystals they have straight edges and flat faces.

  1. Now I know what happened to all the salt. I like your idea of using the crystals, I can’t wait to read your story….
