UNIT FRAMEWORK

NAME / GRADE / SUBJECT
Crayons and Ice Cream / 2nd / Physical Science
UNIT Focus: States of Matter
ESTIMATED LENGTH OF TIME:
60-90 minutes
ESSENTIAL QUESTION(S)/OUTCOME(S)
Are some changes in states of matter reversible?
Are there some changes in states of matter not reversible?
TARGETS
I can make a claim that the materials tested did not change properties when
heat was added and I can support my claim with observations.
STANDARDS/TOPICS/SKILLS
SCIENCE
2-PS1-4. Construct an argument with evidence that some changes caused by heating or cooling can be reversed and some cannot. [Clarification Statement: Examples of reversible changes could include materials such as water and butter at different temperatures. Examples of irreversible changes could include cooking an egg, freezing a plant leaf, and heating paper. / TECHNOLOGY
ISTE 2 Communication and Collaboration
Students use digital media and environments to communicate and work collaboratively, including at a distance, to support individual learning and contribute to the learning of others.
  1. Interact, collaborate, and publish with peers, experts, or others employing a variety of digital environments and media
  2. Communicate information and ideas effectively to multiple audiences using a variety of media and formats
  3. Develop cultural understanding and global awareness by engaging with learners of other cultures
  4. Contribute to project teams to produce original works or solve problems

ENGINEERING
Building background on the Engineering Design Process:

Discuss the need for a growth mindset when designing and testing. Know that making mistakes and things not working right is how we learn! / MATH
CCSS.MATH.PRACTICE.MP3 Construct viable arguments and critique the reasoning of others.

NOTES FOR CLASSROOM TEACHER:
This ABC Mobile Makerspace Lesson is a culminating lesson to be used at or near the end of the Matter Physical Science unit.
When doing this lesson it would be more efficient to start the lemonade cooling first, then do the crayon melting, and go back to the lemonade pops. Even though the lesson is written with the crayon part first.
NOTES FOR MAKERSPACE STAFF:
Need to purchase ice on the way to the school for the lemonade pops. Can ask the teacher to store in the freezer during the week (detail to be arranged in advance).
COMMUNITY PARTNERS (industries, businesses, agencies, colleges, universities)
Possible connection to industry through the use of molds in manufacturing. Teachers may want to use Oregon Connections to help them find local industry experts to either come into the classroom to share what they do or visit with a virtual meeting.
