Extensions/Provocations (Small Group, Learning Centres, Whole Group, Transitions): 

• Pg. 9 - How many lemons does it take to fill a jug?
  Using a yellow sponge and water, students are invited to estimate and test out how many sponge squeezes does it take to fill a jug (or some sort of container). Educators will model what one sponge squeeze looks like for students to use as comparison tool. Increase container size for further extension. Compare capacity with various containers.
• Pg. 17 - Cup stacking challenge - How high can you stack your red cups? (Provide only 15 cups)
• Pg. 21 - How long does it take an ice cube to melt? First have students determine just by having an ice cube melt in a cup. Provide various possible tools that they could measure time with or ask students what are some tools that they could measure the time with? Change atmosphere, other factors to continue experiment.
