Information for Edgerton Center Molecule Sets

Welcome - we are so happy you want to use our Molecule sets!  However, we are sorry to say since the Edgerton Center can no longer purchase LEGO® bricks in bulk, we aren’t able sell Molecule sets anymore.

How you can make the sets/kits yourself:

1. We have made our documents available for download for free from our website: https://edgerton.mit.edu/molecule-set.  

2. You can purchase the following list of bricks yourself from LEGO.com or bricklink.com. (We have found bricklink.com to be a good source of bricks.) Some teachers have also asked parents for donations of LEGO bricks.    

3. Each module requires different numbers of the LEGO bricks, so you don't need obtain all of the bricks, if the bricks are too difficult to find or too expensive. Each lesson page lists the bricks required for that lesson: Chemical Reactions, Photosynthesis, Understanding Air, and Understanding Oceans.

4. The colors selected below are the standard CPK chemistry colors for the elements. The 2x4 or 1x2 on the bricks listed below indicates the stud pattern (the bumps on the top of the bricks).

5. We placed our bricks in clear plastic boxes to make the kits.  (Photo)

Each Molecule kit (shared by two students in class) contains the following LEGO bricks:

  • 4 orange 2x4*
  • 4 grey 2x4*
  • 4 brown 2x4
  • 8 pink 2x4
  • 8 yellow 2x4
  • 8 light green 2x4
  • 8 green 2x4
  • 12 black 2x4
  • 32 blue 2x4
  • 36 red 2x4
  • 24 white 1x2
  • 4 grey connector pegs*

 

*NOTE: The grey and orange LEGO bricks and the grey connector pegs are not used often. We recommend making a separate Teacher Box to keep all these pieces.

If you wish to purchase plastic boxes, we use Plano 2-3600-01 with adjustable dividers, 11"L x 7-1/4"W x 1-3/4"H. You can buy these directly from the Plano company, or from other suppliers like Grainger, Amazon, or Zoro.

Please let us know if you have any other questions! We’d be happy to help you.
