Back To School Tips For Parents

One of my grad school professors was just featured in the Huffington Post! He wrote a great article on back to school for parents. I love that it’s short and sweet, but a wealth of great advice (especially since he’s got a wealth of classroom experience, so it’s right on the money!).

I’m definitely going to be sharing the article with my colleagues, friends, and family and I hope you’ll find it just as useful!

Ms Frizzle In The News!

I am so thrilled to let you know that Just Call Me Ms Frizzle was just honored as one of the Top 50 Science Teacher Blogs!

Teacher Certification Degrees, the website sponsoring the list has great resources for aspiring teachers. Resources include information regarding teaching degrees, state certification, education related careers, and other helpful tools!

End of Quarter Madness & Non-Traditional Physics Tips

The end of the quarter really isn’t the time to write brilliant posts. Therefore, NSTA posts will have to wait for a couple of weeks.

I’ve been thinking a lot about a new series of posts. I find that the way I run a physics curriculum for non-traditional physics students* goes against the grain of the way things are “supposed” to be. I have found this “against the grain” approach very successful with my students.

At a session with Raymond Serway (the writer of the Holt Physics textbook), I was encouraged about my approach when Serway very seriously spoke about the mistake that most teachers make: trying to cover the material in a more collegiate way and ending up spending September through January on kinematics alone.

I figured that there must be other teachers in the same boat, so I’ll start writing about the teaching techniques, lessons, etc. that have been successful.

Please let me know if there are any particular areas that should be addressed.

 

*My non-traditional classes are made of 11th and 12th grade students who are mostly enrolled in Algebra 2, some have Trigonometry, and only one or two have any Calculus. About half of these students will attend college after graduation and few will take physics at the college level.

NSTA 2011 Here and Gone Again

As promised, I will be writing up some of the sessions I attended this past weekend…since this was my first conference as a presenter, I spent less time in sessions as usual, but I did learn quite a few new tricks!

This weekend was also exciting since the conference was held in San Francisco – thousands of science teachers in a city with a tsunami warning; I can bet lots of lesson plans were changed (including my own) to focus on the current events in Japan.

So be on the lookout for:

  • Parent-teacher communication and involvement ideas
  • How to host a physics-themed haunted house
  • Ways to make the most of the Holt Introductory Physics textbook
  • Accessing understanding of ELL students
  • Skills to help ELL students understand science
  • Exhibit hall highlights

Junk Drawer Science

Junk Drawer Science is a new science curriculum company started by teachers with great resources for teachers.

Welcome to Junk Drawer Science: a result of years of frustration with the out-of-touch, and often-out-of date resources that have been available to us as teachers. We believe that it is time for a revolution in science education. The textbook should be relegated to its proper place. It should be a resource and no longer the focal point of our science classes!

Our mission is to provide engaging materials that stimulate learning in your students. We believe that science should not be expensive, and that the simplest lessons are often the most profound.

At the moment, they have three products available for purchase: a book full of great activities for middle and high school life science classes, a guide to using interactive notebooks in science class, and the game they created called “The Game of Evolution”.

I happen to teach with the Junk Drawer Science owners and can guarantee that their products are worth every penny. They have worked hard to develop curriculum and lesson tools that are effective in the classroom as well as easy to implement on a low (to non-existent) budget.

I guess that makes this a shameless plug: all in the name of providing the world with great teaching resources!

Unfortunately, they will not be at the NSTA conference in San Francisco, so for now, you will have to check them out online.

Triumphs in 9th Grade Science:

The beginning of my career as a general science teacher of 9th grade was rough. There were lots of tears and angry moments!

Now that 3rd quarter is almost over, I have been thinking about what has been successful. Here’s what I found:

  1. Being “mean” – I have had to go way beyond normal human levels of mean and anger. In order to get 9th graders to put their ear buds away and stop tagging on each others’ notebooks long enough to even take attendance took so much stern talking that I could feel my blood pressure go up. My husband even remarked that I was more mean around the house. Obviously, I can’t teach this type of class much longer without burning out, but at least I have them trained to behave more like students.
  2. Bathroom ticket – I think these little beauties were the major success of the year. I have had significantly less classroom management issues since initiating this policy. Each 9th grader gets four bathroom tickets for the quarter that can be exchanged for passes to the bathroom or excused missing assignments. Since they feel they have more control over when they can and cannot “go”, I have had much less of a headache! It has also cut way back on students asking to go every day since they used up their tickets in the first week!

I have one more trick up my sleeve for the rest of the school year; I have challenged each of my classes to finish the year with a class average of at leave 7% higher than it is right now. I am planning on clearing off the bulletin board and putting up the goal for each period. I’ll update it every week so they can keep each other accountable. I promised them a big surprise at the end of the year if they achieve their class’s goal. I have yet to figure out what that surprise is, but the kids seems to be really excited, so I hope it is a good motivator for them!

I’m curious to hear what tricks you have found successful with your tricky classes!

Waves Unit Intro

When I was teaching at a college prep high school last year, my advisor showed me how he always introduces waves via the pendulum. For the life of me I can not remember if that is how I was introduced to waves, but I think it’s fabulous! It was a great lesson today, so I thought I would share:


I have this tiny little pendulum (pictured above) one of my students made me last year, so I set it up and had my students brainstorm every type of physics they observed. We went through the whole list (velocity, centripetal motion, friction, gravity, momentum, energy, etc) and discussed each one for a short bit. Next, I described the importance of pendulums and we brainstormed a list of pendulums in “real life”. Some classes were more creative than others, but the point was clear that pendulums are everywhere.

At this point, I asked students what determines the period (time for one cycle) of the pendulum. The usual mass, gravity, amplitude, and string length came into play, so we attacked one at a time:

  • MASS – the pendulum is essentially in free fall and we know that mass in negligible in free fall, so no need to deal with it here either.
  • GRAVITY – will affect every pendulum equally, so it can not affect individual pendulums diferently.
  • AMPLITUDE – to test this we timed 10 oscillations at a low amplitude and 10 at a high amplitude. The times were almost exact, so the students understood that it does not affect the period.

Therefore, the length is the only variable to affect the period of the pendulum.

Vocab came to play here as we defined amplitude (height of pendulum), period (time it takes for one cycle to occur, measured in seconds), and frequency (number of cycles that occur in a given time period, measured in Hz). I wrote the definition of period and frequency on the board as equations as well as the inverse relationship between them. The students then did a few sample problems from the textbook (Hewitt Conceptual Physics – awesome resource!).

To finish up the period, we graphed the position-time graph of the pendulum and the light bulb went off and the kids realized the connection between the pendulum and waves. They drew a transverse wave and labeled the anatomy in order to conclude the lesson.

We’ll pick up with types of waves and the wave equation tomorrow.
