GLACIERS FOR KIDS WHAT IS A GLACIER

HOW GLACIERS FORM?

Some of the snow on a high mountaintop melts and runs off.
But much of it stays all year round.
The snow that stays becomes hard and grainy, like salt.
As new snow falls each year, the grainy snow underneath is squeezed together and becomes hard as ice.
The weight of all the snow pressing down squeezes out a stream of ice, like toothpaste is squeezed from a tube.
This gigantic stream of ice, creeping down the mountainside, is called a glacier.

 TYPES OF GLACIERS

There are two main kinds of glaciers.
One kind is like a river of ice. It stretches from near the top of a mountain down into a valley below.
The other kind of glacier is like an enormous cake of ice and snow. This kind covers whole mountain ranges and even whole lands. All the land at the South Pole is covered by such a glacier.
Most glaciers move slowly. They travel from only a few inches (centimeters) to about forty feet (12 meters) a day.
But, slow as it is, a glacier is like a big, icy bulldozer. It scrapes, gouges, and shovels up the ground over which it moves.
It picks up everything in its path, from soil to huge boulders, and carries it along. As a glacier passes through a valley, it may dig the valley deeper and wider.
As it moves down a mountainside, it may leave long scratches and furrows.
Glaciers make valleys wider and dig out holes for lakes. Long ago, during the time that is called the Ice Age, great glaciers crept far across the land. They dug many ditches and deep holes in some of the places they passed over. Later, these holes filled up with water and became lakes.
In some places the glaciers left rich soil that they had picked up as they moved.
In other places, they left behind huge boulders that now sit far from the mountains that were once their home.

Leaping into a Frogs World

Nothing beats watching your kids learn about something by direct observation. The wonder in their faces as they see a process unfold and “catch on" to principles that you have talked about is worth the time it takes to think about how to fashion the lesson! Along that line, in order to teach your children about frogs and their life cycle, why not let them actually watch a tadpole grow up?
To do this, find some tadpoles - either in a pet shop or at a local pond or creek - and set up a tadpole aquarium. This isnt  hard to do and pet shop personnel are often quite helpful with tips and advice. And, as your child watches the little critters grow from their early stages to adulthood, you can help him/her to understand what is happening by filling in some essential details.

Frogs are amphibians. This means they are cold-blooded vertebrates - vertebrates have a backbone; they have no scales and generally breed in water.
 
Eggs are laid into still waters where there are no strong currents to threaten their survival. To further ensure that individual eggs are not damaged, each female frog will lay a huge number of eggs in one session. She lays each egg on its own but the resulting batch of eggs will lie in the water in a big clump called spawn.
Spawn of EggsEven with all these safety precautions in place, the existence of a frog egg is quite precarious and few will survive to become tadpoles - the fish-like, infant stage of frogs.




About 6-21 days after the eggs are laid and fertilized, the tadpoles will be hatched out to live in the water. A new tadpole will eat the remainder of the yolk of the egg that it came from and then proceed to try to survive to adulthood - not an easy feat!
 
Young tadpoles have a mouth, poorly formed gills and a tail. They will try to stick themselves onto a water plant for protection until they become strong enough to swim away and look for algae to feed on. Once they can live freely in the water, they can be maintained quite nicely in a properly built aquarium. 
 
Tadpoles can be very sociable creatures, so maintaining more than one is quite feasible. (However, please limit yourself to two tadpoles for each gallon of water in the aquarium in order to give them adequate space.)
 
As time passes, your child will be able to observe four important changes in the growing tadpole. After about four weeks, the tadpole’s gills will be covered over with skin and breathing will begin to take place through the lungs. At 6-9 weeks, tiny legs will sprout on the tadpole, first in the back and then in the front. As this happens, a head will be easier to discern and the body will get longer.
 By about 12 weeks, the next step in frog development - loss of the tadpole’s tail - will be almost complete. (Interestingly, the tadpole will stop eating plants at this point. For nutrition, it reabsorbs its tail and that’s why the tail disappears!) 
 
 
The last step, seen at about 12-16 weeks, will be the conversion of our new frog from vegan eating habits to full-blown meat-eater - bugs should now be offered on the menu, please! The frog will now also be a land dweller and your aquarium should be equipped for this change.
 
By the end of four months, your child should be able to describe the full life-cycle of a frog. Here are some other frog-facts that can add depth to your childs understanding of this animal. 
 

Frogs have very special skin. Aside from keeping its insides together, the skin of a frog is used for taking in water and for breathing. Frogs do not drink the way we do - that is, they do not swallow water. Instead, they absorb it through their skin. This not only keeps them properly hydrated, but is also a way to transport oxygen into their bodies. 
 
 
This transport process supplements the oxygen intake by the lungs. Therefore, a frog needs to make sure it stays nice and moist! If water is not available - either through an in-ground source or through dew - frogs will bury themselves in moist dirt. In addition, frogs can produce a mucous over their skin to keep themselves moist and thus prevent suffocation. A frog sheds its skin at regular intervals - with some species of frogs, this may occur once a day - to maintain an outer layer of healthy, functioning skin. 
Different types of frogs have feet which are suited to their habitats and lifestyles. Tree frogs have sucker-like, sticky disks on their feet to help them climb. Other types of frogs have webbed feet which can help them either to swim or to make them buoyant enough to fly.
 
Some frogs have claw-like feet which are meant to help them dig. The hind legs of a frog are very strong and can help them to jump as far as twenty times their own length. (That’s like us jumping about 100 feet! Have your kids jump like frogs and measure how far they can leap - this may help them appreciate the distance achieved by frogs when they jump.)
 
Frogs have an interesting way of eating their food. They have long, sticky tongues that SNAP out, catch the prey and then roll back into their mouth. Frogs actually have teeth. These are tiny and cone-shaped and their function is to hold the prey in place until it is swallowed. 
 
A frog’s teeth can be found in a row at the front of the upper jaw - maxillary teeth - and on the roof of the mouth - vomerine teeth. Finally, if you’ve ever watched a frog swallow, you will have noted that its bulging eyes close and sink down into its head - these big eyeballs actually push the food from the frog’s mouth down into its throat. Whole! GULP!
 
So, have fun watching your child learn about the life-cycle of a frog first-hand. If you acquired your teaching tadpoles in a pet-shop, then you can now keep the frog as a companion for your kids for a few years. Fact: The average life span of a frog is 4-15 years. So, stock up on those bugs! Leap on!

Create a Report using Tellagami and iMovie

I had a conversation about Tellagami with a group of students yesterday. We had a look at it and worked out what it did and then brainstormed some of the ways we could use it to create evidence of our learning.  Almost immediately they wanted to import their own pictures as backgrounds.  It helped that they were in the process of making a Report on Australian Government so this provided an authentic activty to test it out on.

I really like Tellagami, they are simple to construct and quick to set up and because it only allows 450 characters the students have to be succinct with their words. That is, of course, unless you make a series of Tellagamis and combine them in an iMovie. This is what we discussed with the students. This iMovie took about 30 minutes to make from start to finish, admittedly the research had already been done. This meant you could cut and paste most of the text straight into the script. I was impressed with the finished product.

Steps To Get A Hair Spa At Home

You are a beautiful woman, you have an amazing personality, you are known for your wonderful dressing sense, but your hair always puts you in an embarrassing situation. You spend hefty amounts in hair salon and beauty parlour; it relieves you for some time but again your hair looks dull. If you face this hair problem very often and tired of spending too much money, start a hair treatment at home. Does it sound tough? Dont worry it is really very easy and never puts a load on your pocket also. Hair spa at home does not require anything much expensive or exclusive. Most of the products you need for a hair spa are available in your kitchen only. There are 5 steps of a homemade hair spa which includes- massaging, steaming, washing, conditioning and applying hair mask. Things you need for hair spa: Hair oil of your choice, conditioner (homemade or readymade), hair mask (homemade or readymade).



Step 1: Massage your scalp 

This is the first step to start a hair treatment at home. Massage your head with any hair nourishing oil for 15-20 minutes. You can use olive oil, almond oil, coconut oil or sesame oil. The best is to mix equal parts of all of them and use it. Massage softly with your fingertips. It increases blood circulation and helps increase hair growth.

Step 2: Steam warm hair 

Dip a towel or cotton cloth in warm water and squeeze it to remove excess water. Wrap this towel around your head covering all your oiled hair. It helps oil penetrate deep inside the scalp and nourishes the hair. This step takes at least 15 to 20 minutes.

Step 3: Wash your hair 

Now wash your hair with a mild shampoo. Use cold or lukewarm water to wash your hair. Hot water bath causes dandruff, itchy and dry scalp, and weakens hair roots.

Step 4: Apply conditioner 

After shampooing, apply conditioner on your hair. You can either use homemade conditioner or any market product that suits your hair. For homemade conditioner, boil tea leaves in water and add lemon juice to it. Use this concoction as a conditioner after shampoo.

Step 5: Apply a hair mask 

This last step provides all required nourishment to your hair. You can buy a hair mask from the market or make it at home as per your needs and the things available at home. There are different homemade hair masks that you can try for the treatment.

  • Mix one or two eggs according to your hair length with some coconut oil. And apply it as hair mask. Cover the hair with a warm towel for minimum 20 minutes and then wash off with a mild shampoo. 
  • Mash a ripe banana, and mix with olive oil, egg, honey, milk. Blend and apply on your hair. Leave it for 20 minutes and wash off. 
  • A mixture of banana, honey, yogurt and olive oil also does wonders to your hair. You can also apply this homemade hair mask. 

Now you have learned how to do hair spa at home. Do it once every week or in 15 days and see the difference. You will definitely get the desired results very soon.

Thoughts and Feelings A Sentence Completion Card Game



Thoughts and Feelings: A Sentence Completion Card Game
By: Lisa Marie Arneson

Contents:
  • 35 illustrated cards
About Game:

The rules of the game are very simple. All you have to do, is read the beginning of the sentence and the finish it off.  When I saw this, I knew it was a game I had to get. When I opened the box I looked through some of the cards and was amazed. The beginning sentences were amazing to help little kids with sentence completion. 

I used this game often for the little ones and it not only helped them form sentences, but it often lead to great discussions. For example, on one card, it started off with "Sometimes I worry about..." and then the child would say what they are worried about. By dealing with issues in a fun way, we are not only improving speech but also dealing with issues.

Of all 35 cards in this box, I can honestly say they are very appropriate for children. I think there is only one issue that my child did not have to talk about and so we do not use that card. I would say that this is pretty impressive and worth the buy. 

Pros:
  • Sentence completion
  • Colorful illustrations
  • Encourages feelings
  • Fun way to learn full sentences
Cons:
  • Some of the illustrations on the card are ridiculously distracting. For example the card that says "I am different because..." shows a picture of a bird. My child could not get over the bird and insisted she is different because she is a bird. I now turn the card away, start the sentence and when she gives me a good answer, we laugh at the silly illustrations.
Suggestions:
  • If you child is learning more abstract skills then try turning the sentences into questions. For example back to the embarrassing one, ask your child what makes them embarrassed? You can even ask if they accidentally embarrassed any one. 
  • Take out one card and start off the sentence. After act it out. This will work best mainly for the happy cards but it is a lot of fun for the children.
Age Range
  • 4-6 years
  • Child learning to from sentences
  • Child needing help with expressive language
Bottom Line:

The main reason I got this game was for one of the girls as her speech was very delayed. Sitting down and asking her questions after a while can be very boring. As a result I purchased 
Thoughts and Feelings: A Sentence Completion Card Game as a way to encourage speech in a fun way.

If you have any stories about your children who had a speech delay and what you did to help them, please feel free to share below.

Australian scientists find a vaccine to prevent new strains of flu virus

Scientists at the University of Melbourne, Australia, discovered a new breakthrough in the search for better vaccines to prevent new strains of flu virus. They say, cells known as T-cells could be the key to a universal flu vaccine.

Australian scientists find a vaccine to prevent new strains of flu virus.

They find out why the influenza virus usually avoid white cells that protect the body from infection. The use of T-cells to attack the new virus strain will produce a vaccine that is durable and broad coverage in preventing seasonal and pandemic flu outbreaks.

One of the scientists involved in the study, Professor Stephen Turner, said the study will complement the existing treatment of the flu.


"I want to emphasize that we are not trying to replace the existing vaccine that actually works well," said Professor Stephen as reported by the BBC correspondent in Sydney, Phil Mercer.

Other viral infections

"The problem with the existing vaccine is the virus could change, so we are looking for is value added to existing vaccines so that we can produce not only antibodies but also immune T-cell immunity wider if the virus changes without our knowledge," added Professor Stephen .

In addition to potentially generate a universal vaccine, these findings may also reveal a better understanding of immune white blood cells against viral infections, including HIV and hepatitis C.

Every year recorded between three and five million cases of severe flu. The virus is killing 500,000 people per year worldwide.

Giants Ossuary Discovered in a Pennsylvanian Cave

Giants Ossuary Discovered in a Pennsylvanian Cave





Greenville Advance Argus Greenville, Pennsylvania, June 11, 1885 |
Giant  Human Skeletons Found
     J. H. Porter has a farm near Northeast Erie county, Pa., not many miles from where the Lake Shore Railroad crosses the New York State boundary line. Last week some workmen in Mr. Porters employ came upon the entrance to to a cave, and on entering it, found heaps of bones within. Many skeletons
were complete, and exhibited to the naturalists and archaeologists of the neighborhood. They informed the wondering bystanders that the remains were unmistakably those of giants. The entire village of Northepst was aroused by the discovery, and Sunday  hundreds of people from Erie took advantage of their holiday visit to the scene.  It was at first conjectured that the remains were those of soldiers killed in battle with Indians that abounded in the vicinity during the last century but the size of the skulls and the length of the leg bones dispelled the theory. So far about a hundred and fifty giant skeletons of powerful proportions have been exhumed and indications point to a second cave eastward, which may probably contain as many more.
   Scientists who have exhausted skeletons and made careful measurements of the bones say they are a race of gigantic creatures, compared with which our tallest men would appear as pigmies. There are now arrow heads, stone hatchets or other implements of war with the bodies. Some of the bones are on exhibitation at various stores. One is as thick as a good-sized bucket.
