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. A magnifying glass can help you to see them more clearly, but they will still look tiny. Smaller cells are easily visible under a light microscope. It's even possible to make out structures within the cell, such as the nucleus, mitochondria and chloroplasts. 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
Class Dojo - An Observational Assessment Tool Posted April 3, 2016 by Nick LaFave under Assessment www.ClassDojo.com Class Dojo allows teachers to award and deduct points for students based on observations of certain “behaviors.” In a basic sense, it is a behavior management tool, but customizing some of its features can turn it into a far more useful tool for teachers. It’s easy for teachers to create classes. Each student is represented by a monster avatar (which they can customize). More Than Behavior Management I’m not a fan of using this type of tool to manage behavior, nor am I fond of grading behavior or compliance. After setting up a class, teachers can customize the set of “behaviors” they wish to observe in their students. The video below shows how teachers can use Class Dojo on a computer and a tablet simultaneously. Class Dojo Works on Any Device My Environmental Science students spend a lot of time working outdoors. Parent Communication Class Dojo makes it easy to invite parents to create accounts.

Rethinking the Writing Process with the iPad – Karen Janowski Karen Janowski Twitter Profile On the second day of the conference, the first talk I attended was “Rethinking the Writing Process with the iPad” with Karen Janowski. I am especially eager for this topic as using the iPad as a word-processor is a common way that it is applied and often meets with ergonomic frustration. I know that as a touch typist, I can write well over 90 words a minute. She started by pointing out the flexibility of the iPad which means that these tools are not limited to older children – that we can apply various techniques and processes to students of all ages using the same tool. Students of all ages and skill levels often struggle with good writing. What skills are required for successful written expression? From planning, organization, ideas, critical thinking, knowledge and understanding, communication skills, understanding grammar and spelling, imagination, etc., students need numerous skills in order to be successful writers. Is what we’re doing working? Drafting
