Today was a beginning and an ending. We began the new unit, Energy: Conservation and Transfer and ended the month of November. We are also on the countdown to winter break with three full weeks and then two weeks off. The energy unit has two sections (energy, light) so we will focus on the first part before the break and pick up the second part when we return in January.
To begin the new unit, the warm-up was all about energy and to see how much the students know about it.
I had the class then open their agendas and write down the following important dates:
Quizzes: Friday, December 11
Thursday, January 14
Unit test: Thursday, January 21
Wednesday, December 2: E is due for the project
Tuesday, December 15: F,G,H,I are due for the project
Friday, December 11: winter dance
December 21-January 1: winter break
Thursday, January 14: class/group pictures
Monday, January 18: Martin Luther King Day (no school)
Tuesday, January 19: J,K,L,M are due for the project
Wednesday, January 20: early release day
end of second quarter
Monday, January 25: teacher workday
Wednesday, January 27: begin Earth in the Universe unit
Then I had the students take notes on the first part of the section in the unit. The following is what they need to know:
Energy is the ability to do work, or to bring about change.
· Work is when a force applied to an object actually moves the object. Without motion, there is no work.
· The basic forms of energy are: light, heat, sound, electrical, and mechanical (energy of motion)
· There are two types of mechanical energy: potential and kinetic
· Potential Energy – stored or built up energy
· Kinetic Energy – the energy of motion
· All matter has some degree of heat.
· A light bulb produces two types of energy: light and thermal
· Heat is the rate of how fast atoms and molecules are vibrating. The faster the vibration, the more heat.
· Heat also means the transfer of thermal energy from one object to another
· First law of thermodynamics: energy cannot be created nor destroyed. It can only be transferred.
· The second law of thermodynamics: Heat transfer always moves from warmer to colder
· Heat and thermal mean the same thing
· Increasing or decreasing thermal (or heat) energy causes matter to change from one phase to another (solid, liquid, gas)
· Friction is the resistance that one surface or object encounters when moving over another surface or object
· Friction causes heat to build up. The more friction = more heat
· Electricity flowing through an electrical circuit produces magnetic effects in the wires in an electromagnet
· In an electrical circuit containing a battery, a bulb, and a bell, energy from the battery is transferred to the bulb and the bell, which in turn transfer the energy to their surroundings as light, sound, and heat (thermal energy).
Lastly, I FINALLY was able to upload the video of how to make a Mobius strip to YouTube. It is on my Try This at Home page.
Have a happy and safe thanksgiving break!
Today was the second and final day of our two day week before Thanksgiving Break. I definitely saw a noticeable decline in attendance though that is understandable. I have done quite a few whirlwind trips up north visiting both my relatives in Ohio and my wife's in Pennsylvania and yet getting home in time for Monday morning and another week of school. If you are among those who are heading out of town at some point, I wish you a safe and wonderful trip!
While I did say that today's entry was going to be short, that was not accurate since we did a lot.
Today was also the final day of the unit on Matter: Properties and Change. As I had mentioned before, there was no point in starting a new unit on a two day week before a major holiday. So, we will begin the new unit, Energy: Conservation and Transfer on Monday, which also happens to be the last day of November. Using the same line of reasoning, I will focus on the first part of the unit which is types of energy and cover the section on properties of light in January.
Of course, we still began the lesson with a warm-up to review:
Then we did a review on capitalization and nouns before heading in to the final two activities.
The first activity was not the game. I had planned on doing a Mobius Strip activity since the beginning of the year and told the students about it from time to time. Therefore, this was definitely something that I couldn't change nor would I want to.
What is a Mobius Strip? Well.....it isn't easy to explain but I will try. If you take a strip of paper and glue it into a ring and draw a line from one arbitrary starting point, you will return to that starting point, no more....no less.
With a Mobius Strip, take the same strip of paper and give it a single twist so that it kinks before gluing (or taping) the ends together. Now, begin at a random location and draw a line. You will find that you will cover BOTH sides of the strip before returning to the exact same location. How? Beats me! You will need to ask a math wiz far above my pay grade. The illustrations below shows some examples.
What we did was make Mobius Strips of the Rock Cycle since it is never ending.
The final activity was to play the game that was made. I created a simple board game and students made questions for it. However, only one class had the time to do it so hopefully we can make time for it next week. Below is a slideshow of some student work.
Both today's and tomorrow's entries will be short since this is only a two day week before a major holiday. As I had mentioned earlier, we will begin our new unit, Energy: Conservation and Transfer one week from today when we return from Thanksgiving Break.
Both today's and tomorrow's warm-ups will be a review of what has been learned to keep skills fresh.
Students finished up with their questions for tomorrow's game that reviews everything that was covered this year so far.
The final full week of November has come to an end and everyone is looking forward to a two day week when we return on Monday. As I had mentioned (or alluded to) before, next week will be a finishing-up of the unit, Matter: Properties and Change since beginning something new on a two day week preceding a holiday isn't the best idea. Plus, I am pretty confident that out attendance will be down on Monday and even more so on Tuesday. If your child will not be here on either (or both) days next week then I would like to wish you a happy and wonderful Thanksgiving! If you are going to be among the millions traveling during that time, then I want to add a wish of safe travel for you too!
The weekly email has gone out and I will be sending out a brief one on Tuesday.
The students did one of two things: retake the test or make questions. For those who retested, I had them work in another room to avoid distractions. The ones who remained created questions based on anything/everything covered this year so far for a board game. I need a good 35-40 questions for this to work and on Monday they will write the questions (with answers below) on 3x5 note cards. On Tuesday, the plan is to play the game.
That is all for this week. Have a great weekend and as I mentioned above, if your child will not be here next week, have a wonderful and safe Thanksgiving!
