Yay! The weather was good, so I got to play soccer for today’s PE:

Math ββββ

Multiplying by 10

Well, this one is the easiest! You just add a 0 at the end of the number!

10 = 10 x 1

20 = 10 x 2

30 = 10 x 3

40 = 10 x 4

50 = 10 x 5

60 = 10 x 6

70 = 10 x 7

80 = 10 x 8

90 = 10 x 9

100 = 10 x 10

See? That’s easy! Here is the final multiplication table:

You did notice I said final, didn’t you? I hope you remember all of it now!

Make sure to practice:

Science π¬

Uranus

Uranus is the seventh planet from the Sun. It’s twice as far from our star as Saturn. It is an ice giant – it is made up of ice and rocks on the inside and gas on the outside. It is the coldest planet in the Solar System. It takes Uranus almost 84 years to make a full circle around the Sun and its day is 17.2 hours long. Actually, Uranus’ day is kind of funny because it spins sideways:

It has 21 moons (and the number is growing). Like Saturn, it has rings. However, Uranus’ rings are much smaller and less visible. Uranus’ atmosphere is thick and a little stormy. The surface of the planet is pretty flat.

Rome – science

Some of the most important developments in science that come from Rome are related to building. They have perfected building an arch, which became basis for many constructions afterward. Those arches were very useful when they constructed aqueducts. Those are things that help move water from rivers to fields and cities. Speaking of delivering water to cities β they also came up with plumbing!

Many other cultures used to build those as well, but none as well as the Romans. In fact, many of those aqueducts still stand and portions of some are still in use. Romans didnβt only build great βroadsβ for the water β they were the first ones to make durable (that means they were able to survive for a long time, including through bad weather) roads. Unlike other cultures before them, they didnβt make roads go around obstacles. They were really good at figuring out how to go through obstacles, such as building bridges over water and tunnels through mountains. Those roads are now over a thousand years old, but people still use many of them.

Romans were also great at building big structures. You may have heard about the Colloseum in Rome, the Pantheon or Hadrianβs Wall. Those took a lot of work and thinking! Did you know that they used to flood the stage of the Colloseum and have pretend navy battles in there.

Romans figured out how to tell time. They used sundials, which were kind of watches that used position of the sun to tell what time it is.

Trivia β

The Blue Whale is the largest mammal on Earth.

Word of the day β

Flexible – able to bend easily.

Activity πΊ

I am not feeling too well today, so I will be adding Uranus to my Solar System next week. For now, enjoy this video about the Solar System:
