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: Mapping the chemical reaction…
Homework: As per the TASIS MS school homework policy, there is no science homework due on Monday.
