Song Lyrics:
When you see a v, it sounds like "v"
as in very, very good, or very, very mad,
or very, very, very, very happy,
or very, very, very, very glad!

Lots of names begin with v—
Veronica, Vinny, and Valerie,
Violet, Vernon, Vance, and Vic,
or Victoria—take your pick!

Vee vie vo! Vee vie vum!
Viddle viddle, viddle diddle dee!
A very, very, very merry little song
for the valuable letter v!

When Vera took her vitamin
she played better on her violin.
She also sang with a velvet voice,
but the violin was Vera's choice!

Volcanoes are what Victor likes.
Up volcanoes, Victor hikes.
It's very hot!
But, Victor vows it is not!

Vee vie vo! Vee vie vum!
Viddle viddle, viddle diddle dee!
A very, very, very merry little song
for the valuable letter v!

A few more words that start with v:
vacuum, vent, and victory,
vegetable, vehicle, vine, and vest.
There isn't time to name the rest!

Vee vie vo! Vee vie vum!
Viddle viddle, viddle diddle dee!
A very, very, very merry little song
for the valuable letter v!

Vee vie vo! Vee vie vum!
Viddle viddle, viddle diddle dee!
A very, very, very merry little song
for the valuable letter v!
Letter u!

Duck-billed Platypus for Kids | Learn all about this curious mammal Teacherflix 7 Ansichten • 2 Jahre vor

Have you ever seen a duck-billed platypus? This video for kids talks all about one of the most curious mammals in the world. With a duck bill, beaver tail, and otter foot, the platypus is quite strange. Despite being a mammal, it actually lays eggs instead of experiencing live births. They lay their eggs in underground burrows near water that hatch around two weeks later. The young stay with their mother for only about four weeks before swimming off to forage on its own.

While its features are odd, they all have their use. The duck bill is flexible and soft and has thousands of receptors to help them find food in the dark. Their webbed feet push through water quickly. And their tails act like rudders on a ship. They steer the platypuses where they want to go. Additionally, a platypus can remain under water for nearly two minutes before coming up for air!

Believe it or not, a platypus doesn't have any teeth. When it shovels mud and silt into its bill, it also captures gravel. It uses the gravel to chew and grind food. These shy creatures are also very small. Adults weight only around three pounds. That makes them pretty easy prey. However, male platypuses have venomous stingers on their rear feet that can deliver a poisonous sting to attackers.

We hope you and your student(s) enjoyed learning about this interesting creature! If you want to learn even more, head over to our website and download one of our many lesson plans about animals, full of activities, worksheets, and more!

The Map of Quantum Physics Teacherflix 6 Ansichten • 8 Monate vor

This is the Map of Quantum Physics and quantum mechanics covering everything you need to know about this field in one image. Check out this video's sponsor https://brilliant.org/dos
And grab this poster here: https://store.dftba.com/collec....tions/domain-of-scie

I’ve been fascinated with quantum physics and quantum mechanics for a very long time and I wanted to share the subject with you so I made this map of quantum physics to lay out the ideas within the subject, to set some bounds on it so you know its not endless and to introduce you to lots of concepts that if you are interested in them you can dig deeper. When you are approaching a subject like this that’s so complicated it can be quite challenging because you don’t know where to start and you don’t know how all the concepts relate to each other so hopefully this will put everything in context.

This playlist expands on this video with lots of other more specific videos that dive deeper: https://www.youtube.com/playli....st?list=PLOYRlicwLG3
