My Paintings aren’t White.

We’ve written several articles about clouds. We’ve seen what clouds are, why they are white or grey.  This has led to a question.  When I paint and mix the colours why do they go grey not white?.

What is Liquid?

image

There’s a lovely museum near to us.  In the museum courtyard there is a pond.  At the moment it has tadpoles in it.  Kam loves it, he catches the tadpoles, watches them for a couple of seconds and puts them back into the water.

He began to ask about liquids, why he said liquids and not water I don’t know.  Then, he saw an insect land on the water and stand on it.  Mum, my bees die when they land in water, but those flies don’t, why?

Tell me about liquids.

Why are Clouds White?

Kam loves clouds and the skies.

“Mum, yes Kam”
“Why are clouds in the sky”
“Well, they bring rain.”
“No, not the grey clouds, the white ones, they look like stars, but very close.”
“White clouds are full of water droplets, the same as grey rain clouds.”
“They can’t be, water is clear and you can see through it. The white clouds are white, not clear.  Why are clouds white?”

Visible Planets May 2015 – Mercury and Venus

PlanetsIn April, we wrote about which planets we would be able to see in the sky.  This is May’s post and I hope we get to use it.  It has been a useful post and we even took our own Jupiter photo. (It is in the link given below, but is not a NASA masterpiece!

These are the links for those posts:

Mercury’s colour is yellowish, orange or pinkish.  Its hue comes from the sunrise or sunset sky colours.  It is a pinpoint of light, almost star like.

Visible Planets May 2015 – Mars, Jupiter and Saturn

For us, this is a useful post.  We wrote about the visible planets in April, here is the May version.  It gives us the basics in one place, which kind of helps!

We’ve got our own Jupiter photo below. x The post tells us something about Mars, Jupiter and Saturn – simply a recap. It reminds us where the planets are in the sky, theoretically!

Here are the links for July:

Mars has a red hue to it because iron oxides (rust) covers its surface. Most of the time, Mars glows dimly in the night sky, except when it is directly opposite the Sun, (opposition). When Mars is in opposition, usually every 2 years, it’s at its largest and brightest. Continue reading

Visible Planets

One evening  a few weeks ago – more than a few now, Kam pointed to the sky.  I didn’t know what we were looking at.  Look to the left of the moon mum, there’s a planet.

Oh ok, how do you know that?  Mum, because it’s big, it’s bright, it’s not so sparkly, like you and grandad tell me. Oh, ok.

So, being the expert, I look on the iPad.  Sure enough I scan the area, and oh my, it’s a planet.  It’s Jupiter.  Oh golly gosh.

Visible Planets

Jupiter and Earth's Moon

Mercury, Venus, Mars, Jupiter and Saturn are the brightest planets in the sky.

We can see them with our eyes, indeed they are known as the Naked Eye Planets.  Of course, you must know where and what to look for – pretty amazing we think.

Do Fish Sleep?

I’m not sure what prompted Kam to ask this question.  Perhaps it’s because we saw fish in the pond at the park, (see our post do fish have ears?).  Nevertheless it’s a question asked – several times now.

Fish and Brain Patterns

imageFish do rest, but whether they sleep depends upon how you define sleep.

When people sleep there are specific changes which occur to brain wave patterns and ar processed in the brain’s neocortex area.  Fishes don’t have advanced neocortical development, they don’t display the associated brain-wave sleep patterns.

What are Clouds?

Kam’s cloud question is about their colour. He wants to know why clouds are white.  So, I thought it’s probably wise to find out about what clouds are, before we look at why they are white.

How Clouds Form

Water vapour and salt particles

Clouds form when water vapour in the air condenses into water droplets or ice crystals.

The atmosphere contains microscopic (tiny, tiny, tiny) dust particles, called aerosols.

Do Worms have Eyes?

Worms glorious worms
Worms glorious worms

Kam loves worms.  He is fascinated by them and is kind to them.

When we see a worm on top of the soil Kam stops to find a suitable leaf to hide it from “thieving, naughty” birds.  It doesn’t matter where we are Kam’s on worm lookout.

Kam’s rescues worms from pavements.  We get a leaf or a twig and move them to grass or soil.  If they look dried then we have to give them a touch of water.

What is g-force?

A question about g-force. Why?

Atlantis Shuttle Launch:ISS

Simply because Kam’s wetsuit has g-force written across the front of it.  Here is a conversation between Kam and the swimming pool lifeguard.
“hello g-force”
“Hello, why do you call me g-force, my name is Kam”.
“Oh, but g-force is a great name, it’s a super power”.

Oh my, that’s it. Kam, the super powered 4 year old swimmer. (He can swim, he’s competent, and learning his strokes.)

Kam presses his super power button – “Turn on the g-force super power, catch me if you can”.

What is Gravity?

Kam’s question about g force has led me to write about gravity first. The g force post will be our next post.

What is Gravity?

Gravity
Gravity is a force, here attracting or pulling objects to Earth

Gravity is the force that keeps us on Earth’s surface.

  • Without the force of gravity, we would fall off and float away from beloved planet Earth, with it we are safely grounded.
  • When you throw a ball in the air, gravity makes it fall back to Earth, then you can catch it.
  • Some objects, like the Earth and the Sun, have more gravity than others.
  • Tides are caused by the rotation of the Earth and the gravitational effects of the Moon and Sun.
  • Life on Earth could not exist without gravity.

Why do we See One Side of the Moon?

Phasa of the moon
Moon Phases during a Lunar Cycle

“Why do we see one side of the moon?  Does the moon turn round, because I always see the same patterns?”  Kam asked me these questions whilst we were looking at the included image showing different phases of the moon.

I don’t know if these are questions that small children ask.  I don’t remember asking these sorts of questions.

I’m not sure that it would have occurred to me to think that the moon has different patterns.

To me, the moon was the moon.  I do remember looking at the stars, but perhaps I accepted information without being as inquisitive.
