I was told to submit a question to Askascientist.org and relay their reply. I have not heard back from them. I had asked, “If a yoke of a chicken egg is an example of a large cell, does it have all of the organelles other eukaryotic cells have? Does the yoke have a nucleus, Golgi bodies, endoplasmic reticulum, mitochondria, and ribosomes?   If a yoke does indeed have all these parts, are they microscopic? I would think so. Are the organelles as small as organelles in other cells? If so, does that mean there is just a lot of cytoplasm used as filler?  If the egg is a sex cell, I would think it has half of the number of chromosomes as the bird’s other cells, right? When it is fertilized, does it become a ‘whole’ cell until it begins to divide? I am curious. I just do not get the whole yolk is a cell thing.”

This question was too big to submit. I shortened it to ask, “If a yoke of a chicken egg is an example of a large cell, does it have all of the organelles other eukaryotic cells have? Are the organelles as small as organelles in other cells? If so, does that mean there is just a lot of cytoplasm used as filler?” I was able to successfully submit this series of questions, but as I have said, I did not receive a response.

I decided to try once again. This time I asked a simpler question, one related to genetics. “Is liking the taste of brussel sprouts genetic?”  We shall see if they respond.

An Adventure in Exploring On-line Presentation Options
As a teacher always on the prowl for new and innovative ways to engage my students, I happily checked out a few on-line presentation options.
My students have become proficient at creating PowerPoint presentations so earlier this year, I introduced them to Popplet.com which is a free presentation program wherein the user creates what appears to be a graphic organizer made of bubbles. You can input videos (including YouTube videos), images and text into a bubble. At any point, the user can create a presentation path, connecting bubble to bubble. When in presentation mode, each bubble enlarges and swings into view until the arrow button is pushed changing to the next slide. Popplet.com is free. Each of my students needed an email address to set up an account. They could allow their partners access to the project so they could each work on it at home. They enjoyed the novelty of a new project making tool and the presentations turned out great. One drawback I faced was being able to access the students’ Popplets myself. When the students create a PowerPoint, I can copy it to a flash drive and take it home to grade, but not with the Popplets.
            Last Sunday, I gave Prezi.com a whirl by creating a presentation to use in my classroom on Monday. It was not difficult to figure out how to make the program work. I liked the end product better than the Popplet, but it was more challenging to navigate. The students enjoyed my presentation and I was able to update and expand it between classes. I could share the presentation and have them write things down without their realizing they were actually taking notes. The premise is the same as Popplet.com. You have bubbles in which you can add text or images. The presentation mode is more fun. It makes you feel a little like you are on a rollercoaster.
            I went to both websites, Web2.0: Cool Tools for School and Web Tools 4 U 2 Use to check out some prospective on-line presentation tool, looking for one to use for my endangered species project.  I read the blurbs promoting each option. Many of the choices, like GoogleDocs, emphasized the opportunity for collaboration, which I do not need for this project. The fact that it is an on-line writing tool piques my interest in sharing it with one of my teammates. The majority of options promoted themselves as being able to create slideshows, add music or sounds, in addition to having the capacity for being uploaded and shared with friends.
            What I want is something different, and I think I found it with Glogster.com. It seems to be a site where you can create a poster of information that includes text, pictures, images, and video links. If I am right, I should be able to use my scrapbooking skills to make something intriguing. I have barely started and may crash and burn, but I like a challenge. Have any of you out there had any experience with creating glogs?  Let me know.
