9/11 Earth Science update and homework due 9/18

Hi folks,

Today we spent time on the, very important, concept of variables. We learned some of the definitions of the different variables such as changing, independent, dependent and constant. We also did a lab using a pendulum in order to see how changing the length of the string effected how many swings there would be in 10 seconds.


Homework due 9/18 is to:

Read the Variables chapter in the enclosed eBook.

Do all the questions at the end of the Variables chapter.


Also, answer the following questions regarding today's pendulum lab.


1. What was the dependent variable?

2. What was the independent variable?

3. What were five different constant variables?

4. Create a new hypothesis that can be tested using the same materials that we used today.
