Cell Size and Scale Some cells are visible to the unaided eye The smallest objects that the unaided human eye can see are about 0.1 mm long. That means that under the right conditions, you might be able to see an ameoba proteus, a human egg, and a paramecium without using magnification. Smaller cells are easily visible under a light microscope. To see anything smaller than 500 nm, you will need an electron microscope. Adenine The label on the nucleotide is not quite accurate. How can an X chromosome be nearly as big as the head of the sperm cell? No, this isn't a mistake. The X chromosome is shown here in a condensed state, as it would appear in a cell that's going through mitosis. A chromosome is made up of genetic material (one long piece of DNA) wrapped around structural support proteins (histones). Carbon The size of the carbon atom is based on its van der Waals radius.

10 Best Tools for Teachers and Students to Use in 2014 All teachers have a goal to establish clear, friendly, but authoritative communication with students and their parents. Parent meetings are not the most relaxed environment for the teachers to share their expectations and plans, which is why many educators have started using online tools to make this process easier. As a teacher, I have been using many web-based tools to bring some fun into the classes and make the communication with my students and their parents more effective. I’ve chosen some of the most useful tools to present in this list, which will hopefully be implemented in the teaching techniques of an increased number of educators during the upcoming year. 1. TutorsClass is an online solution for distance tutoring. 2. This website gives you a free opportunity to create colorful flyers. 3.

How I Study... in an Organized Way I'm super crazy about organization. I'm no where near OCD, but anyone who knows me knows that I'm all about things being in order. Perfect example: my closet is organized by type of clothing and then organized by color. I like to know where something is when I go looking for it, but I'll put that in another post. I'll go through this step by step. Syllabi Let's start with the syllabi. Once an assignment, test, or reading has been finished, I highlight it so I know that it's done and I don't need to worry about it anymore. Planner My planner is my sidekick during the semester. My planner, much like everything else in my life, is color coordinated. Moving On...... Here's how I get my weekly assignments organized so I can do them: I like lists. I pick a color for each subject, and make a list on a piece of notebook paper, the Stickies on my laptop, and organize my syllabi with the corresponding color flag tags.

Free video lectures,Free Animations, Free Lecture Notes, Free Online Tests, Free Lecture Presentations DIY Ultimate Note-Taking Notebook This is sort of mid-range between what I do and a Moleskine. What I do: 1. Take a regular pad of yellow notepaper (glued at the top). 2. 2a. Cheaper than other systems, only takes a few minutes to accomplish, still includes removable paper for easy scanning, and no guilt for using a $20 notebook. I do this because I really can't justify the expense for note-taking. (I do carry a small Moleskine notebook, the cheap paper-bound one, for on-the-fly note taking). But, of course, I read Lifehacker religiously so, sooner or later, I'll try something like this.

It's Plantin' Time! One of the most anticipated science units in my classroom is our study of life cycles. We spend most of our fourth quarter studying the life cycles of plants, butterflies, frogs, and mealworms. It's one of my most favorite times of the year and one that my kiddos really look forward to! However, we had few glitches! We started out with a parts of a seed lab, observing, writing and comparing predictions about what we would find inside of our seeds. After a couple of days we got this and had to start over! I love how this student included the mold in her diagram! We labeled diagrams of plants and wrote about the job of each plant part. You can grab a copy of these charts in my TPT shop {HERE} Throughout the unit we read several nonfiction books about plants, used thinking maps to label the parts of the whole, categorize the parts we eat, and illustrate the stages of the life cycle. We also incorporated some comprehension strategies with this little cause and effect activity.
