Introduction to Density

Categories: Early Learners

Grade K ages 4-6:  Students will be introduced to density and what makes an object sink or float (or flink, which is neither float or sink).


Students will test out different objects to see what will sink or float. We will also use raisins and carbonated soda to create a reaction that allows the raisins to sink then float and then sink again. This will be followed by an egg experiment using salt that will allow the egg to neither sink nor float.


  • Program is available for Grades K ages 4-6
  • This program is available by appointment only
  • Min 15, Max 35 students.


Learners make estimates, measure and pour ingredients and observe and consider the structure and properties of matter.  They plan and carry out the steps necessary to experience and observe density.  (NGSS PS1-1 and PS1-2)
