Hello friends! Welcome to a new Happy Learning video. Today, we are going to learn about the distance there is between one place and another. Or how we measure the height of a giraffe… Today, we are going to talk about what it is and how to measure longitude.

As we said before, longitude is the distance there is between two points, for example the distance between your house and school.

The most important unit of length is the meter and it is represented by the letter m, 100 m are 100 meters.

The meter measures distances but it also measures things such as the height and width.

This giraffe, for example is 5 meters long and this swimming pool is 25 meters long and 10 meters wide.

But what happens if what we want to measure is smaller than a meter? It’s easy peasy! We need to divide the meter in equal smaller parts.

If we divide a a meter in 10 equal parts… We call each of these little parts a decimetre and we represent it with the letters dm. A meter has 10 decimetres.

If we divide it in 100 equal parts, we call these units centimetres and we represent them with the letters c and m. A meter has one hundred centimetres.

And so, if we divide the meter into 1000 equal parts, we call these tiny parts millimetres and they are represented by two m’s. One meter has a thousand millimetres.

To measure these smaller units we use a ruler o a meter, which as you can see, divides each centimetre into 10 equal parts, in other words, in millimetres.

To measure larger distances than a meter, we use the kilometre, that is exactly 1000 meters.

For example, did you know how much distance there is between Spain and Mexico? Well there are 9025 kilometres and by plane, we take about 10 hours travelling this distance.

Well, now we’ve learnt the units to measure the longitude, but there’s something you need to bare in mind. Not all countries use the meter as a means of measuring longitude.

In England, and United States for example, the units used are yards and miles instead of meters and kilometres. A yard is equal to 914 centimetres and a mile is 1.609 meters.

It’s a bit strange that we don’t all measure in the same units, but that’s what the world is like.

Animal Behavior- Imprinting

Imprinting is an animal behavior in which new born birds and some mammals follow one of the first objects they see.
First mentioned by Konrad Lorenz it helps animals recognize their mother and other similar animal.

A simple test to see if a number is prime or composite. All you do is find the square root of the number. Next, find all the prime numbers of this number. If none of these prime numbers are a factor of the number then the number is prime.

I came across these four physics puzzles over the years in discussions with Neil deGrasse Tyson (riddle 4: which part(s) of a moving train are going backwards with respect to the ground?), Simon Pampena (riddle 2: run around a track twice, the first time slowly, the second time much faster so that the average for the two laps is twice the speed of the first lap). Someone tweeted me a video of the mystery cylinder rolling down the ramp in riddle 1 (sorry I'm not sure who it was). Riddle three about a bicycle going forward or backward when it's bottom peddle is pulled back was brought to me by a number of people and I appreciate all of their help!

Thanks to everyone at the Palais de la Decouverte! I've had this footage for five years and am only finally releasing it now. I wanted to talk about the way grass grows on a spinning turntable but I couldn't locate the footage...

I took a boat through 96 million black plastic balls on the Los Angeles reservoir to find out why they're there. The first time I heard about shade balls the claim was they reduce evaporation. But it turns out this isn't the reason they were introduced.

Huge thanks to LADWP for arranging this special tour for me. Next time let's put the GoPro on the submersible!

The balls are made of high density polyethylene (HDPE) which is less dense than water so they float on the surface of the reservoir even if they break apart. They are 10cm (4 inches) in diameter and contain about 210ml of water. So the main reason they are on the reservoir is to block sunlight from entering the water and triggering a chemical reaction that turns harmless bromide into carcinogenic bromate. This effect occurs with prolonged exposure to bromate so regulators insist that levels be kept below 10 microgram per liter on average over a 12 month period.

What makes an arachnids an arachnid? Spiders and mites are examples of arachnids. First arachnids are arthropods and in addition, they have 8 legs, no antennae, and no wings.
Spiders are arachnids and come in a variety of sizes and shapes.
Spiders are not insects, but instead, they are Arachnids.
Although a spider and insect have many of the same traits spiders have only two body segments and eight legs instead of six.
