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. 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.

Diversity In Nature :: SeenAndShared.com :: Best Quality! 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 "Diversity is the magic. The greater the diversity, the greater the perfection." - Thomas Berry "We are eternally linked not just to each other but our environment." - Herbie Hancock "We cannot afford to be separate. . . . "I know there is strength in the differences between us. "Uniformity is not nature's way; diversity is nature's way." - Vandana Shiva "Share our similarities, celebrate our differences." - M.

unprofound.com : royalty free phototography project - a public domain stock photo collaboration 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! 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} We also incorporated some comprehension strategies with this little cause and effect activity. Happy planting, teacher friends!
