PE 🏃‍♀️

Our workout this morning is to strengthen your core. That means getting your stomach muscle stronger:

Math ➕➖✖➗

What comes after 0? 1 of course! So today, we will be working on multiplying by 1. It’s only a tiny bit harder than multiplying by zero. Any number times 1 is that number.

Here is your video with me showing you how to multiply by 1:

Here is your multiplication table for today:

Science 🔬

Earthquakes

Earthquakes are when the whole ground shakes and they are called seismic activity. It happens when the Earth needs to release pressure from tectonic plates pushing against each other. Tectonic plates are kind of like trays on which continents sit and they move very slowly around the planet. Earthquakes usually happen along the fault lines, which is where the tectonic plates touch each other. These events can be of different strength. Some of them, you can’t feel and some are so strong that they can destroy buildings. Seismic activity can cause cracks in land, volcanoes to erupt, landslides (that’s when ground on a hill or a mountain slides down) and tsunamis (that’s a huge wave on the ocean when the movement of the ground causes water to move).

It’s pretty much impossible to have heads-up when an earthquake will happen. Scientists can tell where they are likely to take place and what’s the chance that they will happen. They can’t tell for sure, though, that they will happen in a specific place at a specific time. You usually find out when things around you start shaking. In many ways, advice for what to do is similar to a tornado, except you don’t have time to run to a basement or another room. Get away from windows and cabinets – you don’t want stuff out of cabinets and shelves, like books or dishes, falling on you. Find a place you can hide, like under a table and make sure to cover your head.

Pyramids

When you look at a pyramid from a side, it looks like a triangle, but when you look from the top, it’s a square. The ones in Egypt are made of stone and are the same color as the sand around them. The most famous ones are in Giza, but there are some smaller ones around the country.

The pyramids were built as tombs for the pharaohs. Do you remember how I said yesterday that Egyptians believed they needed their bodies after they died? That’s why they needed big tombs like that. Their bodies were turned into mummies and put in sarcophagi (that’s multiple of sarcophagus, which is a fancy coffin). The pyramids had many chambers and were basically huge palaces for the dead pharaohs. They also put inside their treasures and regular objects one may need in regular life. When archaeologists got into the pyramids, they found things like furniture and dishes. Also, the walls were covered by hieroglyphics (more on those tomorrow), which told stories of the pharaohs and the country during their reign. We have learned so much from the pyramids!

Fun fact: do you remember me mentioning Cleopatra, one of the last rulers in Egypt? Less time has passed between the time she lived and today than between the time when the pyramids were build and her birth.

Trivia

Poison ivy produces a skin irritant know as urushiol, which can cause an allergic reaction like an itchy rash on the exposed skin.
