Week 15
Week 15 - Balloon Blowup
What did we learn this week?
This week we worked with chemical mixing. Our group decided to test chemical mixing by placing vinegar in a container and placing baking soda in a balloon. When mixed, although it changes from a liquid mixture to a gas/carbon dioxide, the amount of matter does not change. We discover this by weighing the balloon and vinegar filled container before and after the chemical reaction.
This can be used in my future teaching as we worked on ways to engage questions that allow students to begin thinking and getting excited about science concepts. The question we posed to this particular experiment
What remaining questions do you have?
Would it be possible to pop the balloon if you were to create a mixture that created too much carbon dioxide?
Hi Hanna! I think your remaining question is a great point because I know we were trying to discuss this during our lab today! Very nice job!
ReplyDeleteHello, Hanna! The balloon blow up experiment would be a great way to engage students and encourage them to ask questions, and then it results in a better understanding of these concepts as well! Great job.
ReplyDeleteHi Hanna!
ReplyDeleteI really like your question, and I think that would be a great question to ask students after they have experimented with other ways of mixing vinegar and baking soda. I also think the students will really enjoy the balloon experiment because it is cool seeing the balloon blow up, and even when you touch it the balloon is cold.
Hello! I was also wondering about the question you asked as we were doing this experiment. I think it would make the experiment more fun and engaging if something crazier, like the balloon popping, happened at the end.
