PISA 2 Science and Engineering Practices Matter and Its Interactions Workshop for Elementary Teachers Grades 3 - 5 October 7, 2013 Carol Shields Tom Smith
2
Overview of the Day Recap of summer institute – Big Ideas Claims and evidence in teaching Models in science More work with chemical reactions and solutions Planning your unit and lessons Engineering Design
3
Summer “Matters” Measuring Matter Properties of Matter (Water) Mixtures and Chromatography Chemical Change and Physical Change Chemical Reactions and Solutions Mystery Powders Density – Sinking and Floating Engineering is Elementary
4
Strategies to Enhance Science Instruction The Standards and NGSS Using Notebooks Models of Matter Probes/Formative Assessment Claims and Evidence Word Walls Integrating Language Arts into Science
5
Solutions and Reactions The Big Idea Materials in the world around us can be transformed in chemical reactions. The Focus Question What happens when two substances are mixed in water?
6
I. Chemical Reactions We will be investigating three substances in this activity: Baking Soda Calcium Chloride Citric Acid
7
A Review of Solutions What are the parts of a solution? How can you make a solution? How do you know if a mixture is a solution? What does “solubility” mean?
8
Let’s Review! Did a chemical reaction take place in Cup 1? How do you know? What is your evidence? Did a chemical reaction take place in Cup 2? What is your evidence? Did a chemical reaction take place in Cup 3? What is your evidence?
9
Let’s Review What new products formed? What are reactants and products?
10
What’s the Takeaway? Some mixtures of substances result in a chemical reaction. During reactions, starting substances (reactants) change into new substances (products). Formation of a gas or precipitate is evidence of a chemical reaction.
11
II. Reaction Products Focus Question Is the liquid in Cup 1 a solution? How could we find out? What substance did you see in the plastic dishes? Where did the salt come from? What happened to the Calcium Carbonate and Vinegar?
12
What’s the Takeaway? Some products of a reaction are soluble and can only be observed after evaporating the solution. Calcium carbonate reacts with acid.
13
III. Reaction in a Zip Bag Focus Question What happens when you mix substances with water in a bag? What happened to the bag? What caused that? Where did the gas come from? What did you find out by doing the reaction in a bag that you couldn’t find out by doing it in a cup? How does the volume of the gas compare to the volume of the substances you put in the bag?
14
What’s the Takeaway? Some mixtures of substances result in a chemical reaction. Formation of a gas or precipitate is evidence of a chemical reaction.

Goals of Coaching ● Coaching and PD are Integrated ● Coaching Cycle ● Focuses on Your Goals ● Designed to Support You
17
Setting Coaching Goals Improve student engagement Increase student autonomy in the scientific process Elicit student thinking Incorporate modeling into science Incorporate evidence based explanation into science Incorporate engineering Effective assessment
