Presentation Tools

This week we were asked to evaluate online presentation tools after experimenting with them. Prezi and Glogster were internet based, while Power Point is software that normally can be used with MS word.

Prezi has a fairly easy to follow format for both the user and the reader. I used a premade format and had a hard time finding out how to change the background for my presentation. A bit slow when working with links. It took a few minutes to find my way around, but with patience I have begun to get creative:  .http://prezi.com/bawkiey9hp0a/manatees-the-gentle-giants/

Powerpoint- There is much to be said about using Powerpoint, I am familiar with the format, I can use as many pages as I need to get my information in, I can fit videos in my pages. Not everyone has the software for Power Point (or the patience to read all I’ve written) which limits the audience.

Glogster – there are distracting ads at the opening page, It took a few minutes to find my way around but once I did, I found the site fairly easy to use. I like that I can use links for websites, giving me an opportunity to share outside information. So far downloading video and images has been easy. The reader can choose to click on any link they choose with Glogster, compared to Prezi’s system of mapping out content.

I am still evaluating both Prezi and Glogster. They both have advantages and disadvantages. I will go with the program that gives me the least amount of difficulty in the long run.

Modeling Tectonic Plate Movement (or how sugary can it get?)

This week I was given the assignment of modeling an Earth movement with my students. Since I don't have a classroom right now I borrowed my friend's two sons and tossed in one of my own. They were a little reluctant to 'work' on a weekend but a little bribery and the promise of sugary snacks did the trick.


I decided to do an activity with tectonic plate movement. In the process, I learned a lot myself as to the specifics of what happens under the Earth, where different plates converge and how they shift. I had to do a lot of reading and certainly a LOT of writing for the portfolio write up of this inquiry. As usual, a week and a half of writing, editing, contemplating and planning took up the majority of my time. What looked like a simple lesson plan was actually a masterpiece (in my mind!) in the making. 


First, I had the boys tell what they knew on a sheet of paper, which they passed to the boy on the right until all 3 boys added their comments. This gave me an idea of what they knew and to what depth. Sean is older than Keegan, who wrote the second comment (*is struck with awe*). Keegan is a little self conscious of how much his brother knows and he does not, hence the comment. The third student, Chris, added a simple comment (convection currents) which is an important part of tectonic plate movement that Sean did not originally mention. 

This next paper was started by Keegan, who had nominal knowledge of tectonic plate movements. That was fine with me, and gave me an idea of what depth of knowledge  I would need to  teach him new concepts.

The next step was my engagement activity. (If I were to do this in a standard classroom, I would do this on one day and the next day I would have my students do the main inquiry with frosting and graham crackers). I had the boys take Snickers bars, crack the candy shell and manipulate the candy in different ways, modeling basic plate movements. They especially liked the divergent movement and made little mountains last out of their candy bars, which when done they proceeded to eat. 

After I had the boys watch a short video from National Geographic on tectonic plate movement along with a discussion, the boys were ready to use models to create plate shifts on their own. They modeled continental-oceanic collision, transform plate boundaries, divergent plate boundaries and continent to continent plate boundaries using vanilla frosting for the asthenosphere, chocolate frosting for the lithosphere, fruit leather for oceanic plates and graham crackers for continental plates. I let Keegan refer to  the sheets showing the different types of tectonic plate movements while I talked all of the boys through the task. 

Here's an example of an oceanic rift from a divergent plate boundary. The asthenosphere is almost showing under the thin layer of lithosphere:  

Here's an example of Continent to Continent collision. The boys realized that they were creating a small 'mountain range' without my prompting. 

To wrap up the lesson, I had the boys write a summary. I thought Sean did an outstanding job, so I will share his example:

If I were going to do this lesson over again, I would have done the candy bar inquiry on one day and the graham cracker/frosting tectonic plate modeling the next day. I think the boys were a bit overwhelmed by the end, then again they had had an awful lot of sugar in one sitting.

Natural Disasters and Students

Here in Florida, our most prevalent (and notorious) form of natural disasters is the hurricane. We have not had one in several years but as you know they can happen spontaneously. Hurricane season is fairly long; from May 15^th to November 30^th yearly.  One year (2004) four hurricanes swept through central Florida, creating massive devastation that still leaves scars on the countryside.  Hurricane Katrina in nearby Louisiana, with winds striking the area at over 125 mph, created the worst disaster in the country by hurricane since 1928.

It is one of our state standards to teach preparedness yearly. SC.5.E.7.7: Design a family preparedness plan for natural disasters and identify the reasons for having such a plan.

Some of my students remember the hurricanes of 2004, while others (like me) have moved to Florida after 2004. I always teach preparedness as part of my lessons on weather, starting with a discussion about their experiences. We then brainstorm a list of items a family will need as well as things that they will need to do to get ready. Most of the time they don’t think of odd things like putting your patio furniture in your pool, and filling the bathtubs with water for the family to use.

I then show the kids short videos as well as have them check out the FEMA website for preparedness: http://www.fema.gov/hazard/hurricane/index.shtm. After that, the students make brochures which are sent home to be shared with their families, who sign and return them to me.

The Red Cross is a natural for helping others out. In the past, my students have proposed having a bake sale, washing cars and selling handmade crafts to raise funds for those in need. Unfortunately we were not able to do so due to school protocol. I did encourage my students to donate from home, and helped out by matching funds for the donations.

Awesome websites for kids – Physics version

I think the most difficult part of this week’s assignment was in getting myself to stop playing with these websites and start writing about them instead.  I used many of these websites with my classroom this week as part of a review for our state tests. My students were fascinated and deeply involved when checking out these websites, it was all I could do to get them off their computers and out the door for lunch. 

This website had to have been my favorite. The graphics were excellent- ForgeFX simulations paired with the textbook publisher Prentice Hall to create over 100 simulation based learning applications, this is just a sampling. Student’s computers have to be able to download Adobe flash. In my class, some of my student’s computers were able to and some not, which created some frustration for my class.

I have used the cell structure sim as well as the solar system sim with my class via my Smart Board, although my student’s favorite was the design and test simulator.

The next site is called the Strange Matter Exhibit. It’s all about materials science, introducing the field to students, with a link to videos with scientists that work with materials along with some great interactive activities like Zoom!- where kids examine the structure of materials, Materials Smackdown, where kids learn about the properties of materials, The Transformer where kids learn about processing materials and lastly, the Change The World Challenge, where kids explore the performance of materials.

Then there’s the yuckiest site on the internet- http://yucky.discovery.com/flash/ this website was created for Discovery Kids. There’s a page for science fun and games with well thought out explanations for our future doctors and scientists; subjects like Gross and Cool Body, Roach World and Worm World are a blast to investigate.

Exploring Heat Transfer

This week's inquiry experiment was fairly simple on paper; fill four identical mugs, pour some hot water into them and cover each with a different insulator found around the house. Leave the covered mugs on the counter for 30 minutes and then measure the temperature change with the thermometer from our science kits.

There was no stipulation as to how hot the water needed to be so I put each mug in the microwave for 2 minutes each, then covered them and left them out. Half an hour later I attempted to measure the temperature and discovered that my little thermometer could only reach 50 degrees Celsius. Sooo....I had to toss that experiment. Unmeasurable= Invalid.

Next, there was a lively debate between my fiance, my fiance's son who is an AP student in science and myself. We went back and forth on whether I should microwave the water or use hot tap water, if I should do all the mugs at once or one at a time and what insulators I should use. That's typical for my house, being surrounded by smart people is lively if not informative.


I decided to do it my way. I usually do. I heated tap water to its hottest, measured one cup of water, put it in the mugs and topped them. I came back half an hour later and checked the temperature. Strange, how on earth could the plastic baggie be the best insulator? Something had to be wrong, I had also used a 1" piece of Styrofoam, a piece of foil and a wash cloth as my insulators. Surely the washcloth or the baggie had to be poor insulators but no, it didn't work that way at all.


So I sighed, and did the experiment once more. It sounded so simple on paper!


This time when I measured the results, the water for  the Styrofoam, the baggie and the wash cloth all measured in at 36 degrees Celsius. What was up with the Styrofoam? It ended up that the foil won out with a temperature of 37 degrees Celsius.


I decided to leave my experiment at that. Maybe foil as an insulator was something I could look into later on in my free time. It also occurred to me as I was pondering the results that this experiment had no control and to get truly valid results, I would have included a control.


My conclusion: I wouldn't have my students do an experiment like this having tried it on my own with three widely different results. If I was instructed to have my students do it despite my objections, I would give more specifics; give a starting temperature for the water, and to make sure they used a control.


And now for a question from my professor:
What, specifically, would you like students to learn from this experiment?

To answer that question, I pulled up the Sunshine State Standards for Fifth Grade-

The Nature of Science
Standard 1:
The student uses the scientific processes and habits of
mind to solve problems. (SC.H.1.2)

Standard 2:
The student understands that most natural events occur
in comprehensible, consistent patterns. (SC.H.2.2)

6. knows ways that heat can move from one object
to another.

Did you achieve this goal when you engaged in the experiment?

To be honest, I did not. The experiment shows that insulators work to contain some heat, but does not show where the heat went nor how it escaped the coffee mug.
