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.

Microscope Imaging Station. Neurons: A Fish-Eye View of the Brain Speed-dating neurons make connections Researchers in the Smith lab have also been able to watch the development of single neurons as they grow and connect to each other to complete the optical system. What they’ve seen helps explain how the brain's enormous complexity emerges. It now appears that brain organization happens in stages. As a developing neuron grows, it sends out tiny exploratory branches called filopodia. These projections search for partners in an effort to make connections and form synapses. Diversity "Diversity is not about how we differ. Diversity is about embracing one another's uniqueness." - Ola Joseph "United we stand, divided we fall." - Aesop (620 -560 B.C.)

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.

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! Our end of the year open house falls during this time and we made these flower booklets from myLife Cycle of Plants unit to showcase our plant study. However, we had few glitches!
