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. ARKive - Discover the world's most endangered species Wildscreen's Arkive project was launched in 2003 and grew to become the world's biggest encyclopaedia of life on Earth. With the help of over 7,000 of the world’s best wildlife filmmakers and photographers, conservationists and scientists, featured multi-media fact-files for more than 16,000 endangered species. Freely accessible to everyone, over half a million people every month, from over 200 countries, used Arkive to learn and discover the wonders of the natural world.

Celebrating Science - A Family Science Project Whether we realize it our not, everyday we ask ourselves critical questions that involve science. Should I vaccinate my child? Should I buy a hybrid car? Do pesticides on food harm my family and me? For this reason, students graduating from K-12 schools need to develop a basic level of scientific literacy. Whether addressing a mundane or momentous issue, a solid foundation in the sciences is critical for every individual's success and the advancement as a society. 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.) "Diversity: the art of thinking independently together." - Malcom Forbes "Love the one you're with." - Stephen Stills

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! It was crazy-time there for a few days!

Wolfram Eukaryote Eukaryotes can reproduce both asexually through mitosis and sexually through meiosis and gamete fusion. In mitosis, one cell divides to produce two genetically identical cells. In meiosis, DNA replication is followed by two rounds of cell division to produce four daughter cells each with half the number of chromosomes as the original parent cell (haploid cells).
