100 Very Cool Facts About The Human Body The Brain The human brain is the most complex and least understood part of the human anatomy. There may be a lot we don’t know, but here are a few interesting facts that we’ve got covered. Nerve impulses to and from the brain travel as fast as 170 miles per hour. Hair and Nails While they’re not a living part of your body, most people spend a good amount of time caring for their hair and nails. Facial hair grows faster than any other hair on the body. Internal Organs Though we may not give them much thought unless they’re bothering us, our internal organs are what allow us to go on eating, breathing and walking around. The largest internal organ is the small intestine. Bodily Functions We may not always like to talk about them, but everyone has to deal with bodily functions on a daily basis. Sneezes regularly exceed 100 mph. Sex and Reproduction As taboo as it may be in some places, sex is an important part of human life as a facet of relationships and the means to reproduce. Senses

Concept Cartoons Concept cartoons är ett bedömningsstöd och inspirationsmaterial för de naturorienterande ämnena i årskurs 1-9. Materialet bygger på teckningar där elever uttrycker sina tankar om olika fenomen eller sammanhang i vardagen. Meningen är att de ska väcka intresse, skapa diskussioner och stimulera naturvetenskapligt tänkande. Skolverket har i ett avtal med utgivaren i England, Millgate House Education Ltd, fått rättigheter att översätta Concept Cartoons till svenska och erbjuda materialet för lärare som undervisar i de naturvetenskapliga ämnena. Materialet är därför lösenordsskyddat och finns i Skolverkets bedömningsportal. Ladda ned materialet För att ladda ner Concept cartoons nedan krävs användarnamn och lösenord.

More Beta Cells, More Insulin, Less Diabetes Caption: Betatrophin, a natural hormone produced in liver and fat cells, triggers the insulin-producing beta cells in the pancreas to replicateCredit: Douglas Melton and Peng Yi Type 2 diabetes (T2D) has arguably reached epidemic levels in this country; between 22 and 24 million people suffer from the disease. But now there’s an exciting new development: scientists at the Harvard Stem Cell Institute have discovered a hormone that might slow or stop the progression of diabetes [1]. T2D is the most common type of diabetes, accounting for about 95% of cases. The hallmark is high blood sugar. It is linked to obesity, which increases the body’s demand for more and more insulin. Treating diabetes costs the U.S. a veritable fortune. The NIH-funded researchers set out to try to identify a signal that seems to be sent by the liver to the beta cells when the insulin receptor is blocked and blood glucose levels rise. It’s not every day that a new and important hormone is discovered! References:

Concept Cartoons These concept cartoons were developed by Dianne Anderson and Kathleen Fisher (2002) as prompts for eliciting discussion about ideas in evolution. They can also be used as assessment tools. The cartoons are best suited for college non-majors and pre-college classes. The incorrect statements in the cartoons are derived from common naive conceptions. Cartoons can be downloaded in PDF format and can be transferred to transparencies or paper copies so long as the copyright notation to Anderson and Fisher is retained.

Cuttlefish: Chameleons of the Sea Butterfly Life Cycle: Article with Lots of Pictures Bees in Hive The Butterfly Life Cycle Let’s explore a butterfly’s life cycle in detail, including all four stages of life. All butterflies have "complete metamorphosis." To grow into an adult they go through 4 stages: egg, larva, pupa and adult. Butterfly Eggs on a Leaf A butterfly starts life as a very small, round, oval or cylindrical egg. Butterfly eggs are usually laid on the leaves of plants, so if you are actively searching for these very tiny eggs, you will have to take some time and examine quite a few leaves in order to find some. Butterfly Caterpillar When the egg finally hatches, most of you would expect for a butterfly to emerge, right? When the egg hatches, the caterpillar will start his work and eat the leaf they were born onto. Caterpillars need to eat and eat so they can grow quickly. Caterpillar Becoming a Chrysalis The pupa stage is one of the coolest stages of a butterfly’s life. Monarch Caterpillar Becoming a Chrysalis Butterfly Emerging from a Chrysalis Google +

Très intéressant pour une révision en classe sur la photosynthèse. Avec les gros plan, on peut bien située celle-ci. Néanmoins, la qualité de la voix de l'animateur laisse à désirer. Si vous désirez utiliser ce vidéo pour enseigner, je recommande de faire vous même les explications en désactivant le son lors d'un cours. by juliendemers Jan 26
