Coffee Filter Chromatography Butterflies:

Which markers made the prettiest colors?


Capillary action: The movement of a liquid along the surface of a solid caused by the attraction of molecules of the liquid to the molecules of the solid; The movement of water within the spaces of a porous material due to the forces of adhesion, cohesion, and surface tension.

Solution: a homogeneous, molecular mixture of two or more substances

Solubility: relative capability of being dissolved

Bath Bombs:


Ph: A measure of how acidic/basic water is. The range goes from 0 to 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base.

Endothermic: A chemical reaction or physical change is endothermic if heat is absorbed by the system from the surroundings. In the course of an endothermic process, the system gains heat from the surroundings and so the temperature of the surroundings decreases

Exothermic: If heat is released by the system into the surroundings during a chemical reaction or physical change. Because the surroundings are gaining heat from the system, the temperature of the surroundings increases. 

Library Resources

We are super excited to be working with the Lincoln Library! They have curated book and website lists for students of different ages to learn more about chemistry! Visit the library website to access these resources!

We are also partnering with the Goodnow Library in Sudbury! Their booklist can be found here: https://goodnowlibrary.org/gearticks-collaboration-stem-resources-for-kids/

General Guiding Questions/Suggestions:

  1. Which chemistry project did you decide to do?
  2. What substances were combined, and did a reaction occur?
  3. How did the substances change during your experiment? 
  4. Do some research on the science behind how your experiment worked.

Reflection Questions:

  1. What was your favorite part of the challenge?
  2. Did anything unexpected happen?
  3. What challenges did you overcome? 
  4. What did you learn?
  5. Did you have to change the ingredients and how did that change the results?
  6. How did you make your project colorful or creative?
  7. What was your favorite part of the experiment? 

If you tried a chromatography experiment: 

  1. Describe what happened to the ink as the water moved through it.
  2. What type of matter do you think the ink is in the other color you used?
  3. The separation of matter depends on the physical properties of the substances involved.  In this chromatography experiment, what physical property or properties were used to separate the matter?
