Online Visual Dictionary

February 16th, 2011

Hi!  It’s Wednesday, February 16, 2011 and time for Language Arts at ClickSchooling!

Recommended Website:
The Visual Dictionary

Age Range: All (with parental supervision)

This site was recommended on my Unpreschool Yahoo Groups discussion list – but it’s for learners of all ages. 

It offers a free online Visual Dictionary. It’s different from a regular dictionary. Instead of just word definitions, it provides colorful visual images that enhance the meaning of the words and concepts you explore. Concise textual definitions (in three languages) are included, but it’s secondary to the images.

When you get to the site, you’ll see an icon menu of the list of topics that are in The Visual Dictionary. I suggest you click on “List of Topics” on the menu tab because then you can see each topic area with a drop-down list of what it covers as follows:

*Vegetal Biology – See images (with text) that define and describe plant cell structure, structure of a leaf, leaf shapes, types of roots, flower germination, diagram of the stages of mitosis, fruits, vegetables, and much more. 

*Animal Biology – Learn about the structure of a bacterial cell or an amoeba or paramecium, find out about the anatomy of an earthworm, starfish, jellyfish, snake, frog, fish, shark, fly, bee, cricket, spider, bird, bat, cat, dog, deer, gorilla and more.

*Human Biology – Explore cells, muscles, skeletal system, finger nails, parts of a tooth, nervous system, eyes, ears, nasal and oral cavities, digestive system, respiratory system, human heart, reproductive system, and more.

*Music – Discover a wide variety of instruments from around the world including Europe, India, China, Africa, and South America. Get info on percussion, wind, brass, and string instruments. Learn about music notation.

*Transport – Learn all about automobiles, trucks, motorcycles, trains, boats, planes, hot air balloons, and rockets. Get details on engines, air filters, brakes, shock absorbers, tires, and more.  Explore roads and bridges.

*Clothing – Everything you ever wanted to know about clothing and accessories including info on cultural differences in styles. Check out uniforms and costumes too!
 
In addition to the visual images in this dictionary, you’ll also find some videos that promote learning.
 
This is a great reference tool. Just exploring The Visual Dictionary is sure to springboard interest in a wide variety of topics. Bookmark it to return often.

Enjoy!

Biology for Kids

February 8th, 2011

Hi!  It’s Tuesday, February 8, 2011 and time for Science at ClickSchooling!

Recommended Website:
Biology4kids

Age Range: 9 and up (approximately, with parental supervision)

This website is part of the 4Kids series of sites (some of which have been featured on ClickSchooling previously). This one, Biology4Kids is an ad-supported site that offers engaging information, activities and resources for learning Biology.

When you get to the site, directly below the headline, you’ll find a menu of the general categories that will take you to active learning pages and quizzes that include:

*Studies – Discover the Scientific Method, Logic & Reasoning, Animal Kingdoms, Taxonomy, Species and more.

*Cell Structure & Function – Learn about Membrane Proteins, Cell Walls, Chromosomes, Mitochondria, Vacuoles and find out the meaning of Passive Transport, Active Transport, Pinocytosis, Mitosis and Meiosis.

*Plants – Explore the anatomy of a plant and learn about Photosynthesis,  Reproduction, Mosses & Liverworts, Ferns & Horsetails, and more.

*Activities – Take quizzes to see what you’ve learned, and watch informative slide shows and videos.

*More Topics – This section contains a menu of everything available on the site as described above, plus information about:

  • Microorganisms – Check out microscopic images of Viruses, Bacteria, Fungi, Lichen, Microbes and more.
  • Invertebrates – Get an overview of spineless critters such as Sponges, Starfish, Jellyfish, Round Worms, Insects, Spiders, Scorpions and more.
  • Vertebrates – Learn about Fish, Amphibians, Reptiles, Birds, and Mammals.
  • Animal Systems – Explore the Skeletal, Muscular, Circulatory, Respiratory, Digestive, Reproduction, and Nervous systems.

In each section of this website you’ll find information, illustrations, and diagrams along with quizzes, slideshows and videos to enhance learning.

If it’s all a little confusing, simply follow the “On Site Tour” by clicking on the button near the bottom of each page.  It will take you through all of the material on the site in a prescribed order.

While most of the links on this site work, I did run across a few that didn’t work. However, by clicking around a bit I could find my way to the page that the link referenced. 

IMPORTANT: It is very easy to mistakenly click on random Google Ads that are sprinkled throughout the text/pages on the site and wind up off site. It happened to me a couple of times. Therefore, AS ALWAYS, parents must preview and supervise use of the site at all times.

Enjoy!

Free Biology Lessons & Lab Animations

June 15th, 2010

Hi!  It’s Tuesday, June 15, 2010 and time for Science at ClickSchooling!

Recommended Website:
Prentice Hall: Biology Place

Age Range: 10-18 (middle/high school biology)

ClickScholar Ozboz recommended this website, sponsored by textbook publisher Prentice Hall, that offers free biology lessons and lab animations. This multi-media resource can be used in conjunction with any basic biology textbook or curriculum, or as a fascinating exploration for the incurably curious. 

When you get to the website you’ll see a menu of three items:

*BioCoach – This section is designed for reviewing and enhancing biology information gleaned from textbooks and classroom lessons. However, the animations and interactive aspects really help all learners (including those outside classroom walls) to visualize and understand biological concepts including:

  • Biomembranes
  • Biomolecules
  • Cardiovascular System
  • Cell Structure and Function
  • DNA Structure and Replication 
  • Meiosis
  • Mitosis
  • Plant Structure and Growth
  • And more!

*LabBench – This is an interactive virtual lab that helps students further understand basic biology concepts. References are made to actual classroom lab activities (for example, an instruction to look at a slide under a microscope). However, the virtual lab offers a picture of what you would see if you were viewing the slide through a microscope. So, while you might not have the hands-on experience, you can still learn a lot. You can even take a quiz at the end of each lab to see what you retain. There are 12 labs in all that include:

  • Lab 1: Diffusion & Osmosis
  • Lab 2: Enzyme Catalysis
  • Lab 3: Mitosis & Meiosis
  • Lab 4: Plant Pigments & Photosynthesis
  • Lab 5: Cell Respiration
  • Lab 6: Molecular Biology  
  • Lab 7: Genetics of Organisms
  • Lab 8: Population Genetics
  • Lab 9: Transpiration
  • Lab 10: Circulatory Physiology
  • Lab 11: Animal Behavior
  • Lab 12: Dissolved Oxygen

*Glossary – Get definitions of biological words, terms, and phrases.

This is a good resource for introducing biology concepts, supplementing any study of biology, and it can be used to refresh your memory about biology course material as well.

Animated Cellular Structure & Activity

August 14th, 2007

Recommended Websites:

XVIVO: Scientific Animation

Age Range: 14 and up (note: designed for college level biology
students)

List member Nancy Hogan suggested this website that offers an
incredible 8-minute video-animation titled “The Inner Life of the
Cell” that was designed “to transport Harvard Biology students into a
three-dimensional journey through the microscopic world of a cell.”
It moves beyond textbooks and “vividly illustrates the mechanisms
that allow a white blood cell to sense its surroundings and respond
to an external stimulus. This animation explores the different
cellular environments in which these communications take place.”

While it is fascinating to watch, unless you have some knowledge of
cell structure and function it may be difficult to understand what
you are seeing — as no explanation is provided, just musical
accompaniment. If this triggers interest, then use the following
website to develop a foundation to better understand this video…


Cells Alive!

Age Range: 12 and up (younger children may enjoy various aspects of
this site)

Cells Alive was previously featured on ClickSchooling in 2002. The
site has been updated and is really worth visiting multiple times. It
uses animations, interactive and colorful illustrations, and
interesting text to help visitors learn about the many forms and
functions of cells. The categories include:

  • Cell Biology — all about the structure of plant, animal, and
    bacterial cells that includes interactive animation of mitosis and
    meiosis, and a quiz to check your knowledge on cell structure and
    function.
  • Microbiology — get familiar with viruses, bacteria, and parasites
    from E.coli to strep to HIV – and take the quiz on microbes.
  • Immunology —don’t miss the anatomy of a splinter, the workings of
    allergies and mites, making antibodies, and take the quiz on the
    immune system.
  • Microscopy —get the scoop on the latest techniques for cell imaging
    and research and visit The Crystal Gallery for some eye-popping
    microscope images.

Under “Interactive” on the menu, you can examine cell models, view an
animation of the cell cycle, watch the Cell Cams that let you see in
real time how long it takes for cancer cells and bacteria cells to
double. Solve some puzzles and take some quizzes too.

This is a “must see” site for anyone studying the sciences in grades
7 and up. Younger students will find aspects of it interesting too —
parents can preview the site to determine which parts will be of the
most interest to their kids. You will want to bookmark this site and
return often.
