Lift

We just learned about the Air Resistance, part of ballistics which is the science of the forces that move a rocket around.

Another part of ballistics is Lift, which is all about how the air flows underneath a rocket that helps it fly up.

You can feel lift if there is a strong wind and you put your hand out flat, the air will try to push your hand up like a kite.
The way you hold your hand changes how the wind pushes on you, and rockets can use small fins or wings to try and use lift to help them fly.

Octopus Beaks

We just learned about the Japanese Flying Squid.

We've learned about a lot of fun cephalopods, like the octopus, squid, nautilus and cuttlefish!.
Let's learn a little bit about how their bodies work!

An Octopus Body is made up of interesting parts like the mantle, fins, siphons, tentacles, gills, beaks, fins suckers and even things like humans have, like eyes, hearts, arms and skin.

One of the most interesting parts is the Octopus Beak, also called the rostrum, as it is one of the only hard parts of the body for many octopuses.

The beak is made up of two parts, with an upper and lower part that fit together like scissors, and are controlled by jaw muscles just like humans.

It is mostly made up of some proteins mixed in with something called chitin (pronounced like kah-ee-tin), which is actually a kind of sugar.

This chitin is hardened so the beak is super sharp and is used by an octopus to break open the shells of animals they want to eat like clams.

Citadel of Qaitbay

We just learned about the Windsor Castle.

Another ancient castle is the Citadel of Qaitbay, built in 1477 AD, in Alexandria, Egypt.

This castle was built in the same place as the Lighthouse of Alexandria, which was known as one of the seven wonders of the ancient world before it was destroyed around 100 years before this castle was built.

It is on the north side of Egypt, right on the Mediterranean Sea where it was a strong place to defend Egypt against any ships that might be coming to attack.

It is now a maritime museum, which is a kind of museum for ships and other seaside things.
