G6 Week 14 – S2

Friday, May 18th

Today in science: Time was given in class to all students who still needed to complete the Acids & Alkalis test. After completing the test, students were asked to watch a few short videos (such as this onethis one, and this one) introducing them to the Makey Makey. Each student was given their own Makey Makey inventor kit in class. The Makey Makey is an educational toy to help students learn about electricity, circuits, conductivity, and programming. It also aims to tap into–and further develop–students curiosity and creativity.

Homework: Students have been asked to video/record one of their successful Makey Makey creations this weekend. They can either send their video to Dr. Merritt via email (brett.merritt@tasis.ch) or bring their video with them to class on Monday.

Thursday, May 17th

Today in science: Test day! Students spent the entire period working on their Acids & Alkalis test. Most students got to within 5-15 minutes of completing all of the questions.

Homework: There is no science homework tonight.

Tuesday-Wednesday, May 15-16th

Today in science: H period science does not meet on Tuesdays. However, there are some practice questions available from the link(s) below. Students were given some time to work on all three of these practice questions during Wednesday’s (shortened) science class. In the case of Question #7, Dr. Merritt did some quick demonstrations of the reactions described in the question with glass test tubes, baking soda, HCl, and balloons.

Question #7
Question #8
Question #9

Homework: Students should continue studying for Thursday’s Acids & Alkalis test from the materials they have available to them.

Monday, May 14th

Today in science: More practice test questions… Today’s practice questions were almost entire about the use of two different pH indicators: litmus paper (or solution) and universal indicator solution (or paper). In both cases, it was emphasized that students will need to know how these two indicators respond when in the presence of acids, alkalis (or bases), and neutral substances. The notes we created on the whiteboard are summarized for students in the links below

A website summarizing the results of red and blue litmus paper, as well as litmus indicator solution. Purple litmus paper, it was said, will turn red in acidic solutions, blue in alkali solutions, and remain purple in neutral solutions.
