Today we’ll start by taking a Quiz over types of waves and the Doppler effect. Then we’ll review the EM spectrum with a video from NASA. Be sure to take notes on each of the classes of EM waves in the video and their applications to help you make a poster later.
For the last part of class, and you’ll make your own EM Spec diagram as a color poster.
You can use the EM spectrum diagram from the blue textbook: p. 70-71
Use a strip of paper from the back bench and Mr. Siedler’s colored pencils.
You’ll be graded on neatness but will also need:
7 classes of waves
Wave Frequency in numbers (Hz) along a line
Arrows showing increasing energy
Examples of the wave source or technology that uses that class of wave
We’ve finished with describing motion and started with what causes motion: the force! After Spring break we will cover Newton’s 3 laws. we’ll do some reading in the text in case my yapping at you doesn’t do the job!
The Last set of notes for this unit! Newton’s 3 Laws of Motion!
We are finally getting to the key part of this unit. Luckily an important scientist has reached out to this class to help us out. Dimitri Mendeleev discovered a pattern in the elements and we will try to do the same.
Here is the message he sent:
Here’s the text of his assignment:
Good day fellow scientists. My name is Dmitri Mendeleev. I need your help! I believe I have seen a pattern in the elements! By creating cards for each known element and arranging the cards by weight and then looking for patterns in their character, I believe I have unlocked the secrets of the elements!Like any great scientist, I need others to confirm my findings. I have provided my data, but hidden the names of the elements. Please collect your data onto cards, then arrange by weight left to right, then look for a pattern. The elements can be arranged into families of characteristics up and down, creating a periodicity in the nature of creation.
Good luck dear scientists!
Our last set of notes is on the Branches of Science. That is, the different forms of science that are practiced around many different subjects and questions. This is by no means and exhaustive list, but is good start at the big branches. Here’s a link to some flash cards so that you can
