Physical Science 107: Challenge

For credit – take a bag with you and walk around one city block looking for plastic items that have been thrown on the ground. Pick them up (you may wish to wear disposible gloves) and collect them in your bag. At then end of your walk take a picture of what you’ve collected and send it to me via email (jwalker@ccc.edu). Then throw the plastic trash away:-)

Physical Science 107: Cabbage pH indicator

Here is the scale of colors for the cabbage juice that tells you the pH. Remember that the solution you test must be colorless or the scale may not match. Use this scale as a guideline. If you wish to prepare this pH indicator read more.

Physical Science 107: Please check the schedule after each class

The schedule of the course: http://justonly.com/physci/ps107/schedule.php is being filled out as we go along so it is always changing as new information is added. Because I’m teaching this course for the first time I am learning how long each lesson takes. I’ve put up the date of the first unit test. The test will cover lessons 1,2,3 and4. Here are some tips to be ready:

1. Be sure you can answer the questions in each unit. If you don’t understand something ask about it in class!

2. Read at least two newspaper stories, more if you can, and write summaries in your journal. The goal of this class is to improve your understanding of CURRENT PUBLIC issues in Physical Science – and so I want to help you understand these news articles better.

3. Develop your glossary. Nobody knows all the words in the English language – but we are always learning new words. As you are reading pick out some words whose meanings you don’t know well – and look them up in a dictionary (book or online). Write the definitions in the glossary section of your journal.

4. On your own – follow the background links – as many as you can. Look around at these websites. Watch any videos that are posted. All this exposure to information will help you develop good questions to ask in class!

5. COME to class. Missing class is the worst thing you can do in this course. If you are there and you are participating you will do well. Be there or be square:-)

See you next class!
