Student lab: Acidimetric titration - Flipped classroom
Flipping of labs is extremely time saving by outsourcing the instruction in homework by an instructional video recorded by the teacher which explains setting up the experiment and introducing the vocabulary
Title of Lesson: Acidimetric titration – German language lesson materials
Lesson Objects:
- How to set up a titration (vocabulary and use of lab ware)
- Perform an acidimetric titration in groups of 3 students
- Measuring pH during titration
- Plot a neutralisation graph using excel
- Explain the shape of a neutralisation graph and its characteristics
Appropriate Greade Levels: Grade 10/11/12 of the German High School system
Subject: Chemistry
Student video link: preparational homework http://youtu.be/33gg06moMSw - has to be done by students at home as preparation of the lab
Activities:
- Setting up the lab ware for titration to start out (groups of three)
- Group discussion on names and function of lab ware
- checking of the setup by the teacher
- Titration in groups of three (one student for titration, data collection (pH/ Volume) and data recording (excel)
Link to the instructional worksheet including a QR code to video - Plotting the graph
- Discussion and comparison with sample graph (using powerpoint) - Powerpoint
Unfortunately the powerpoint presentation looses some of its functionality in slideshare (in actual PPT the rectangles disappear by clicking on them revealing the solution).
