Sorry I can’t be in class today, kids – I know you’re disappointed to have a cover teacher – so here’s the low-down on what you need to do while I’m out:
- Review the homework problems to make sure you have the correct answers and understand the process. The process is more important than the answers.
- Watch the dimensional analysis video linked here, then complete the quiz on that website to verify you understand how to do dimensional analysis.
- Go through my zombie presentation – yes, zombies do in fact know how to do dimensional analysis – and work all the practice problems in the presentation. You may do this with a partner if you want, and I’ll go over the answers with you next lesson.
- Review the document titled, “How to create graphs for science” and create a bullet-point list of all the required parts of a scientific graph. I’ll check this list as another homework check next lesson.
Here’s the zombie presentation:
Here’s the “How to create graphs for science” document in a viewing window:
Here are some tools to help you through the Measurements in Science homework assignment.
The video linked here methodically takes you through the dimensional analysis process, and it includes a quiz so that you can check your understanding.
This page has a lot of practice problems worked out for you, and it explains the process in easy-to-understand language.
Here’s the presentation we’ll use in class. Watch it. Study it. Master it.
Oh, and here’s another link that may be helpful. From Texas A+M University.
Your first unit test is rapidly approaching! It will be a 5-part test on Friday 6 September (9A and 9C) and Monday 9 September (9B). Here are the 5 sections of the test:
- Common equipment – identify by name and use
- Lab safety rules – explain them
- Unit conversion and dimensional analysis – like the HW assignment
- Demonstrate use of graduated cylinder, electronic balance, and Bunsen burner
- Create a data table and a graph from given raw data
Please note that part 4 is a demonstration stage. Each student will be called to the central demo table, where I will observe your skills using a graduated cylinder, electronic balance, and Bunsen burner. You will have exactly 2 minutes to accomplish 3 tasks with these tools, so please make sure you are comfortable using them!
The test will be scored under Criterion C (Scientific Knowledge) and Criterion F (Attitudes in Science).
