STEM Challenge 2: Rainbow Jar

  For this week's STEM Challenge, we learned about liquids, density, and molecules to make a Rainbow Jar in honor of St. Patrick's Day.
    We began with two cups of marbles and decided that the cup with the most marbles was the heaviest.  I explained that liquids with more molecules were denser and heavier.  

Throughout the project we compared the density of the liquids we worked with.  Scroll to the bottom to see the finished project!
