Performance expectation: Develop and use a model of ionic compounds to identify patterns in the chemical composition of salts and salts’ electrolyte properties. Overarching Question: How should we search for life beyond Earth? Today's DRIVING question: Why is water so essential to life? To answer this we will investigate:
Do Now:
Make business cards Learning Model Tracker (already done), read it and tape it into your notebook on a new page. Date your page 9/26/22. After this, you will be adding to a similar graphic organizer to track what we figure out during each lesson that helps us answer our Driving Question. -------------------------------------------------------------------------------------------------- Assessment: Student Electronic Exit Ticket (Exit from Lesson 4) -------------------------------------------------------------------------------------------------- REVISIT the Jamboard questions you came up with on Friday. Which questions should we work on next to figure out more about water and it's ability to conduct electricity when there is water in it. Begin Lesson 5 with some background connections and thinking. PLEASE open your notebook to the next open section under today's date. ANSWER the following questions. (Also on the Slideshow) 1. We have new knowledge of how charge can be transferred from one object to another (water + balloon; balloon + wall; tape). How might that information help us explain the differences we noticed when we tested the conductivity of deionized water, salt water, and sugar water? 2. Which macromolecule images included positive and/or negative charges? SLIDESHOW What ideas do you have about why these ions are so important for life? 3. How do we think conducting electricity might relate to water’s importance for life? 4. How might we investigate how or why salts conduct electricity? What ideas do you have for substances we could investigate? Build our own conductivity meters. Here are some ideas on how:
