Lesson 1 - Tuesday, Mar 10
Today in science: We prepared our science notebooks for this week’s INV#6 – Chew On It! This meant making a Table of Contents entry, creating a page entry, writing a Research Question, and learning the Method/Procedure to be used in the first part of this investigation. This also meant performing Experiment 1, which involved testing both sugar and starch solutions for the presence of a complex carbohydrate known as “starch.” It also involved testing a whole cracker for the presence of starch!
Homework: There is no science homework tonight.
Lesson 2 - Wed, Mar 11 (C, D) & Thu, Mar 12 (E)
Today in science: We continued our work on INV#6 – Chew On It! This meant performing Experiments 2 and 3, which involved a) putting powdered cracker into beakers of water and saliva, and b) putting a whole cracker into our mouth to see how long we could keep it there without swallowing. During the investigation students were also asked to record the definitions of two important types of digestion: physical and chemical.
Homework: There is no science homework tonight.
Lesson 3 - Friday, Mar 13
Today in science: We began and completed a new investigation today, INV#7 – Digestion in a Bag! This investigation helped students think about both digestion in the mouth and the stomach, and introduced the concepts of “pH,” “acids,” and “alkalis” (or “bases”). Students also had the opportunity to use Universal Indicator solution and Universal Indicator paper. It was also supported with a video about testing for Acids & Alkalis.
Unlike other investigations, this is not one we entered into our science notebooks. Instead, students were given a handout on which they recorded their results.
Homework: As per the TASIS MS school homework policy, there is no weekend science homework due on Tuesday (as there are no classes on Monday due to Parent-Teacher Conferences).
