#### Lesson Plans

 Name Description Physical Science Unit: Water Beach Vacation Lesson 8 Coding a Simulation: Changes to Water Students will use logical thinking, decision making and flowcharts to code a simulation about the state of matter the water will be in, dependent upon water temperature. Students will use a free online block-coding platform called Scratch. This is a lesson in the Grade 3 Physical Science Unit on Water. This is a themed unit of SaM-1's adventures while on a Beach Vacation.  To see all the lessons in the unit please visit https://www.cpalms.org/page818.aspx. Physical Science Unit: Water Beach Vacation Lesson 7 Planning a Simulation: Changes to Water Students will use logical thinking, decision making and flowcharts to plan a coded simulation about the state of water, dependent upon water temperature. Students will then be able to use that flowchart and code their own simulation using a free online block-coding platform called Scratch. This is a lesson in the Grade 3 Physical Science Unit on Water.
