Välkommen till SvampGuiden - allt om svamp och svampar Teachers | Classroom Activity | Dogs and More Dogs Objective To learn through an evolution card game how selective pressures can affect an organism's evolution. copy of the "From Wolf to Dog" student handout (PDF or HTML)copy of the "Examining the Game" student handout (PDF or HTML)copy of the "Wolf Deck" student handout (PDF or HTML)scissors1 die Scientists know all dogs descended from the gray wolf, but they don't know exactly how that happened. Tell students that in this activity they are going to engage in a simulation to learn how selective pressures can affect an organism's evolution. You may want to review the following terms with students: gene: A segment of DNA that codes for a particular protein. gene pool: All the genes of all the members in a population. selective pressure: Any environmental factor that favors one trait over another. mutation: A random change in a gene or a group of genes. species: Any group of organisms, the members of which successfully breed with each other, producing healthy, fertile offspring.

Extreme weather makeovers | National Geographic Kids This primary resource helps children to think about the effect of the weather and change of seasons on the creatures that live in extreme weather environments. Discover how the weather changes the look of some animals. What changes does the change in weather ignite in the animals mentioned? Why does white fur help to insulate the animals? Why is climate change a problem for the Arctic fox? Pupils will learn about extreme weather; snowy Arctic and subarctic winters, and how the weather impacts the animals that live in those conditions in our National Geographic Kids’ weather primary resource sheet. The teaching resource can be used in study group tasks about extreme weather, as a printed handout for each pupil, or for display on the interactive whiteboard. Activity: Divide the class into five groups and assign each group one of the animals from the resource to create a fact file about. N.B. National Curriculum Key Stage 1 Geography objective: Pupils should be taught to: Oops!

KDE Santa Barbara Welcome to the Kids Do Ecology Biomes Pages! Aquatic Biomes | Terrestrial Biomes | GAMES! What are biomes? Would you like to know what the weather is like in different biomes around the world? How many biomes are there?

Next, students learn that different types of rabbits prefer to eat different varieties of plants. Students make the connection between rainfall amount and the rabbit population's ability to survive by thinking first about rainfall and plants, then about plants and rabbits. » Teacher Guide PLEASE NOTE: This activity can be assigned, but student responses will not be saved.

Växter Det finns drygt 300 000 kända arter av växter i världen. De minsta är bara ett par millimeter stora medan de största träden kan bli mer än 100 meter höga. Läran om växter kallas botanik. De flesta organismer som kallas växter har pigment som gör att de kan omvandla solenergi till socker. De gröna växterna utgör en grupp och indelas bland annat i blomväxter, barrväxter, ormbunksväxter, mossor, kransalger och grönalger. Till växter brukar man även föra grupper från andra utvecklingslinjer, till exempel svampar (inklusive lavar), brunalger och rödalger. Läran om fröväxterna kallas fanerogambotanik. Pollen Pollenprognoser och mätningar har fått en egen webbplats, - besök den gärna! Mer om växter I Den virtuella floran finns finns över 2000 svenska arter (fröväxter och kärlkryptogamer). Museet forskar Vi forskar om växter på följande enheterna: Fanerogambotanik (fröväxter)Kryptogambotanik (svampar, lavar, alger, mossor)Paleobotanik (fossila växter)

Who Evolved on First? Bud Abbott and Lou Costello While I was writing this post, I heard that Bill Nye and Ken Ham are planning to have a debate about evolution and creation. While it could be an interesting conversation, I suspect that it will suffer from the same communication problems that afflict most of these debates. Have you ever heard the brilliant comedy routine, “Who’s on first?” by Bud Abbott and Lou Costello? While this is a hilarious comedy routine, it also serves as a beautiful example of what usually happens when scientists and non-scientists get into discussions about controversial topics such as evolution, climate change, genetically modified organisms, vaccines, etc. An excellent example of that is evolution. Evolution is on first. There are many words with scientific meanings that are very different from the meanings used in everyday conversations. On a very generic level, the word evolution means change over time. No more Evolution! What in the world does that mean? That is changing.

Teachers For Teachers You can use Dive and Discover as a resource for: Extensions of existing lessons Homework assignments An introduction to a science unit A class project One lesson Multiple lessons during science unit With Dive and Discover, your students are at the frontline of scientific inquiry as they join scientists—geologists, chemists and biologists—who are exploring the seafloor and making amazing new deep-sea discoveries. Daily updates, photos, videos and email correspondence with scientists from these research vessels allow your students to follow the progress of the scientific missions and find out about life on the floating laboratories at sea. Strategies for Incorporating Dive and Discover in the Classroom With the aid of educators involved in previous Dive and Discover expeditions, we have created a list of suggested strategies for use in the classroom.

How Do Flamingos Stand on One Leg? | Wonderopolis Today’s Wonder of the Day was inspired by Bob. Bob Wonders, “How can flamingos balance with one leg?” Thanks for WONDERing with us, Bob! We were getting ready to watch the sun set over the Wonderopolis waterfront the other day when we overheard an interesting conversation between a sea gull and a flamingo: Sea Gull: Hey there! Flamingo: Nice to meet you, Babs. Sea Gull: I'm new to the area. Flamingo: Oh year? Sea Gull: No, I know you're pink because of what you eat. Flamingo: Ha! We firmly believe that Frank was just pulling Babs' leg, but their conversation did make us WONDER about exactly why — and how — flamingos stand on one leg while they sleep. Standing on one leg is not natural — or easy — for human beings to do for any length of time. Scientists who have studied flamingos have observed this behavior for a long time. Some think that flamingos stand on one leg to dry it off from time to time, since they spend so much time in the water.

NOVA | The Zoo of You By Neil Shubin Posted 10.26.09 NOVA You may not feel much like a shark, fruit fly, or worm, but you share many aspects of your anatomy and physiology with these and all other animals on Earth. All the various bits and pieces of you–organs, bones, nerves, even your genes–show up in different but fundamentally similar forms in other animals, in some cases animals that lived half a billion years ago, revealing how all creatures on Earth, including you, are just variations on a theme. Launch Interactive In this interactive, see how closely parts of your body match those in other animals, from sharks to fruit flies. Neil Shubin is professor of anatomy at the University of Chicago.

Why bluetongue lizards’ tongues are blue Bluetongue lizards use their tongues as a last-ditch effort to avoid being eaten, according to the latest research from the Lizard Lab at Macquarie University in Sydney. Other videos and images at The base of their tongue is particularly bright under UV light – which birds can see clearly. The lizard relies on camouflage to avoid hawks and other predators. “Blue tongue lizards have a highly conspicuous tongue, but unlike many other kinds of lizards, it’s a big tongue—the surface area is large. The researchers, Associate Professor Whiting, Pau Carazo, a postdoctoral researcher at Macquarie (now at the University of Valencia) and Sam Price-Rees, placed blue tongues in a large-outdoor enclosure, where they held them briefly in order to test their behavioural responses to model, or fake, predators. “Blueys did not respond much to the piece of wood (control) while they showed a strong response to the model predators that would normally represent the greatest threat.
