About Crackle and Pop!

There are 100+ experiments and activities in Crackle and Pop! that can be integrated with the Old and New Testaments.  Each STEM experiment and activity can be completed alone or combined with a story from the Bible.  The image below shows only a small portion of what you can find in the book.  Homeschooling families, private school teachers, camp counselors, and church group leaders would be able to find lots of things to do in this book!  

Note: Because of the Christian nature of Crackle and Pop!, public school teachers and teachers in Jewish and Muslim private schools may or may not find this book helpful.  There are a lot of terrific STEM ideas in Crackle and Pop!, but you may need to pick and choose which experiments and activities you can use in the classroom.

Bible Stories

On each double-page spread in the Crackle and Pop, Hanna Holwerda presents you with a passage from the Bible and several STEM and science activities parents and teachers can integrate with it.  For example, there is a collection of Noah's Ark-themed activities to go with Genesis 7 and 8.  The author suggests that you read the story of Noah's Ark with your students to set the stage for the experiments.  You can either read the story directly from the Bible or from one of the countless picture books available online.

There are 75 pages of Noah's Ark and Noah's Ark related children's books on Amazon that you can use with this activity (affiliate link).

Floating or Sinking STEM Experiment

One of the STEM activities Hanna Holwerda included Crackle and Pop! is a traditional sink or float experiment to go with the Noah's Ark story.  This experiment requires a handful of items... the majority of which you probably have already.

For this experiment, you will need:
  • plant-based oil
  • water
  • large glass
  • small toy bricks
  • coins
  • other small objects

The first step of this experiment teaches students about density and displacement.  I added a drop of blue food coloring to the water to highlight the difference between the two layers.

Directions:
  1. Fill the glass halfway with water.
  2. Slowly pour some oil into the glass.  Do NOT let the oil and water mix!
  3. Drop the small objects into the glass one at a time.  Which ones float?  Which ones sink?  Which ones appear to be stuck between the two layers?

The second step of this experiment teaches the students about sink vs. float.  We dropped all sorts of random items into the jar... buttons, coins, cough drops, screws, and glitter.  The buttons floated on top of the oil.  The glitter floated on the water, but not the oil.  Everything else sunk to the bottom of the jar.  Fun times!
