Branches of Science

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

here’s another with no definitions:

The Nature of Science: NoS

For the last section of our introductory unit, we’ll cover the philisophy and place of Science in in our society.  This is often called the Nature of Science.

We started with our long set of notes (great job every body!) discussion what Science is, and what it can and can’t do:

We ended with some quick practice outlining what science can’t do: here

On the next day we talked a bit more about how science depends on evidence and that we must begin with a “falsifiable”  testable idea.  Not like the Dragon in My Garage: 

So there are limits to what science can address but with clear thought and cleverness it allows it to answer amazing questions. Here’s a TED-ed that I think does the job:

To make this work science depends on a process and some rules. we’ll talk about this process in our Scientific Method Notes:

On the third day of our mini-unit we’ll investigate how this works in reality by examining the case of the KT boundry hypothesis.  or listen to the audio.

We’ll get a chance to do it ourselves too: with fossils of Xenosmilius.

 

 

Metric System and Measurement

The next section of our introductory unit this year is a review of some basic science skill you should have entering high school.

We used these notes to review the Metric System: it’s origins, its basis, what the main units are.

Our practice assignments from in class included:

We also spent a bit of class time making sure we understood the difference between MASS and WEIGHT.  Here’s a reminder. 

Let’s end with a fun review of the Metric System (SI) :

Safety and Equipment

Today we’ll be talking all about the safety rules to follow in the classroom and laboratory and the equipment we’ll be using.

These are the slides for the Lab Equipment talk.  Please be sure to study them, do the matching assignment, and create a set of flash cards.  There is a quiz the next time we meet!

Here is an abbreviated set of notes for you to use to learn the pieces of equipment and study them.

Here’s our safety rules

and our assignment reviewing those rules.

To finish up we saw some safety videos:

 

We’ll Finish up Safety and Equip this week with a quick assignment on SDSs (formerly MSDS). These are vital pieces of Chemical Safety information which I guarantee your next boss will require you to know about.

We learned the first 10 sections of the MSDS now called the SDS document.  These documents accompany chemicals in a workplace and give vital information to those using the chemicals.

Here’s the Video link to the OSHA Training video

Here’s the OSHA Reading, The SDS Prep Assignment (worth points), and the handy dandy guide document.

If we finish with the assignment we can start introducing the Metric System by the end of the day.

 

Assessment on MON. On Nature of Science.

A reminder about our assessment on Monday (Tue b-day)

I’ve tagged the relevant posts with “NoS” so that they are easy to find.

We covered:

  • What IS and what IS NOT Science
  • The Sci Method
  • Theory Law Hypothesis and Fact and Belief
  • And the Branches of Sci, especially those available at WHS

Here’s a good video to review Theory, Hyp, and Fact:

STEM Carreers

Today we begin our STEM Careers project.  We began with a reading: STEM 101.  Then a survey, and then began to choose our field of interest.  Once we know what we are looking for (see the project) then you can use the below sites to start your research.

More on the Nature of Science: The Method.

This lesson focuses on the Scientific method.  I hope you leave class today with a sense that there is a consistent process that science follows, but that it is also flexible and different for every situation.  Our process that we will have in this class goes like this:

  1. Observation/Question
  2. Form a Hypothesis (prediction)
  3. Experiment Design  (test)
  4. Record and Analyze Results
  5. Draw Conclusions (interpret)

Here’s our short set of slides (some of this is review)

and the embedded video is here

Lastly we did a reading on the Nature of Science and the Method and answered some questions from the reading.  THIS is DUE Next Class. (Mon/Tues)
