Science 4 Lesson 18

Termites have a clear way of differentiating soldiers and workers. Soldier termites have a red shell around the head. The workers have the pale heads.

The termite’s home is very intricate. In Africa the hot sun makes many animals go underground. With so many animals breathing underground it gets hot with less oxygen so the termites build tall mounds. The tall mounds have a hole in the bottom to let up hot air. The towers have pores to let in the breeze which is cool. Then the wind blowing around the tower pulls the hot air out the other side.

This is a termite queen. Some queens can lay 164,250,000 eggs in their lifetime. Queens keep the same mate for their whole life which is about 15 years.

Science 4 Lesson 17

Bees, like most insects, start out as eggs that are white and pretty long.

The larva is like the egg but is larger and has wrinkles.

Then the larva turns into a pupa which also is white like the previous stages.

Then the pupa turns into the bee itself.

How New Building Tools Impact Architecture

One building tool that has impacted architecture is the crane. The crane has made it so that we can build quicker and taller structures. Cranes have 2 key components that are the pulley and winch. The pulley is a basic invention that redirects and focuses force. Say your trying to pull a block straight up but it is too heavy for you and you have to pull it straight up higher than you are so you have to use a pulley because it lessons the weight and goes straight up, still too heavy for you? Add another pulley. The winch is a wheel that you can turn. Combined they make the crane a giant pulley that uses a wheel. We use the crane to make buildings that stand straight up, since we don’t have to use ramps.

Science 4 Lesson 12

Sunset moths like all moths start out as an egg.

The sunset moths caterpillar looks like it got pooped on by a bird and then sprouted feathers.

Then the caterpillar unlike the butterfly spins silk all around itself.

After a few weeks of being in the cocoon the caterpillar changes into a moth.Strangely, moth wings when not in use lie down on the body whereas butterfly wings stand up when not in use.

Science 4 Lesson 11

The Monarch Butterfly like all other butterflies starts out as an egg.The Monarch Butterflies egg is green with white lines in it.

The egg then hatches into a caterpillar which looks like a very strange tiger.

The caterpillar then sheds its exoskeleton into not a caterpillar but into a chrysalis.

After weeks of changing in the chrysalis the butterfly finally emerges, dries off its wings and takes flight and lays another egg

New military inventions can shape the outcome of a war

New military inventions can shape the outcome of a war. The sword is a weapon that we do not know the origin of but do know that it has been in use until the 19th century when firearms became popular. The sword has 2 key components which are the hilt and blade which in turn have different pieces. The blade has an edge, a fuller, and a point. If the sword is to cut or hack at something the edge should be sharp but if the purpose of the sword is to stab then it does not matter whether the edge is sharp or dull. The fuller is a scooped up portion of a sword that does not take away from the strength or rigidness of the sword but does make it lighter and easier to use. The point was originally rounded which was okay since the armor was light and easy to cut through. But as the armor got stronger the sword had to adapt so the point was sharpened so that all the strength was focused on one point. The hilt has a grip, a pommel, and a crossguard. The grip is a piece of wood that is covered in sand paper-like material. The pommel is there to stop your hand from sliding off the grip and acts as a counter weight to the heavy blades. The crossguard is there to stop your hand from sliding onto the blade and act as a small shield to protect your hand from the other sword. That is one military invention that has changed the outcome of wars.

Summer Vacation

My favorite thing I did last summer was when I went on a car trip to Colorado. One thing we did on the trip was drive to the grand canyon and it really looked like a painting! Another thing we did was drive to the Four corners and I bought a cool coin from one of the shops there. Another thing we did was drive to Mesa Verde.Those ruins look really cool! We also went to the Adventure Dome in Las Vegas. And when we got to Colorado we had fun with my family.So my favorite thing I did last summer was when I went on a car trip to Colorado.

Science 4 Lesson 7

The ladybug starts as an egg and hatches into a caterpillar which I did not know.The caterpillar has three legs and just drags its butt around!

The caterpillar then turns into a pupa which I also did not know.You can see the spots on the pupa but when the ladybug hatches it does not have spots.

after being in the pupa for a while the ladybug finally hatches into the beautiful ladybugs we know today.

science 4 lesson 6

I have observed that beetles have 2 antennae, that their back legs are on the abdomen when i thought they were on the thorax. They also have 3 pairs of legs and lots of species spit out acids from their butt.
