10.A Students apply scientific ideas and evidence (property data) to construct an explanation for whether the gas(es) produced from water using energy from a battery were made of the same particles (patterns) as those produced from heating the water.
What to do
See Sample Student Response for Written Explanation for guidance.
Go over to the Adding Energy to Water Investigations poster. Direct students attention to this poster. And add sticky notes with check marks to both of the ideas for investigations the class has now completed.
Say, Let’s take stock of where we are. We have tried both of the investigations we wanted to do with water based on what we read about. And you all just constructed an explanation based on evidence we collected that new types of particles were produced from water particles in one of the investigations. That seems directly related to the key idea we summarized at the end of Lesson 8, related to what had shown on our What is happening with particles when new substances are made? poster. In our next class let’s revisit that poster and evaluate those ideas in light of the explanations you constructed.
