Lesson 1 - Monday, Apr 27
Today in science: One focus question for today’s lesson is, “Are is a gas (or gases) trapped within a bath bomb?” Another focus question for today’s lesson is, “What gas (or gases) could be coming from the bath bomb?” To investigate these questions we set up INV#10 – Investigating Gas From a Bath Bomb.
- We mapped out two investigations that we think can address our focus questions.
- One investigation will require students to trap the gas created (released? produced?) by a bath bomb place within a closed system.
- The other investigation will require students to compare the mass of an uncrushed bath bomb with a crushed bath bomb.
Homework: There is no science homework tonight.
Lesson 2 - Tuesday, Apr 28
Today in science: We carried out the investigation to address one of our two focus questions: “What gas (or gases) could be coming from the bath bomb?” Students have access to our class data with this link: INV#10 – Investigating Gas From a Bath Bomb.
- We performed tests for three different gases: carbon dioxide, oxygen, and hydrogen.
- With a one-of-a-kind demonstration, we also saw the unique properties of a fourth gas, propane.
Homework: There is no science homework tonight.
Lesson 3 - Wed, Apr 29 (C, D) & Thu, Apr 30 (E)
Today in science: We summarized our findings from our Lesson 2 investigation by creating a sort of equation to describe what we know about the bath bomb phenomena so far. In this summation we discussed “reactants,” “products,” “atoms,” “molecules,” and “elements.” We also consulted the labels of some bath bombs to further investigate their ingredients. We then analyzed some of the ingredients to determine the elements they’re made from. Students have access to our work with this link: INV#10 – Investigating Gas From a Bath Bomb.
Homework: There is no science homework tonight.
Lesson 4 - Friday, May 1
Today in science: With the help of a large, A3-size handout, we mapped the chemical reaction created by our bath bombs by examining all of the reactants and products at the atomic level. Students were asked to place the chemicals on either side of the reaction and to justify their choice by supporting it with evidence from our previous lessons. Although we didn’t have time to watch them in all three classes, students might find the videos below fun and interesting!
Homework: As per the TASIS MS school homework policy, there is no science homework due on Monday.
Announcements...
The Driving Questions for UNIT 6.6 (Understanding Chemical Reactions) is: How do we create something new that wasn't there before?
C & D period homework collection days: Wednesday & Friday.
E period homework collection days: Tuesday & Thursday.
KWoW - There is no KWoW this week, but if there was one it would be "chemical reaction."
