Pllama

In science we each created a creature. I created a pllama. It is a combination of a llama and pug. It lives in the French Alps. It starts out at 45 centimeters and grows to be 2 meters. It weighs 45 kilometers. It likes to eat baguettes and croissants. The pllama lives in cool temperatures. It mates with others to have babies. There are only 100,000 living in the Alps. It gets rid of its waist by pooping malt balls.  Pllamas are multicellular and they breathe oxygen. They walk and they use their mouths to eat. Here is a picture.

 

Scientific Summer

Over the summer I went to Washington D.C. and visited the Smithsonians. I enjoyed the National Air and Space Museum. There were so many different planes and rockets like the Spirit of Saint Louis. It was so cool how they got those in the museum. I learned about the history of flight. There were a lot of interactive activities to which I enjoyed.

 

Here’s how planes fly. Plane wings are made to make air move faster over the top of the wing. When the air moves quickly the air pressure lowers. So there is lesss pressure on the top of the wing is less than on the bottom of the wing. The difference in air pressure makes a force on the wing that raises  the wing into the air.

 

This is how rockets work. Rockets burn fuel. Their  engines turn the fuel into hot gas. The engine pushes the hot gas out of  the back. The gas makes the rocket go forward.A rocket engine is not like a jet engine. A jet engine needs air to work unlike a rocket. It carries everything it needs. A rocket engine also works in outer space, where there isn’t any  air. There are two different  types of rocket engines. Some use liquid fuel. Others use solid fuels. On the either side of the space shuttle are the two white rocket boosters which use solid fuels.

 

Cross Section of a Leaf

  In Science we learned about the cells and tissues in leaves. These are the epidermis, palisade, spongy tissue and veins. The epidermis is the leave’s skin. Leaves make their food in the palisade. The spongy tissue is above the lower layer of the epidermis. Veins are long thin tubes that carry food and water through the plant.

Tu B’ Shvat

For Tu- B’ Shvat we went to the U.N.F nature preserve. Three new things I learned are:
Devils Walking Stick is poisonous to animals. It looks like a stick that sticks out of the ground that’s covered in thorns.
Cypress trees have thick trunks that keep them from blowing away in a category five hurricane.
Yellow Bellied Sap Suckers mostly go to sugar gum trees. They peck a hole in the tree and watch the sap come out. Then they fly away and wait for bugs to get stuck in it.
Some things I already knew are:
Blackberry bushes look like poison ivy
How to model a plant.
One interesting fact is Cypress tree roots lock together during hurricanes so they don’t fall over.

Water Cycle

For Tu B’Shvat in Hebrew, Art, and science we’re studying the water cycle.

In Science we did an experiment where we put water in a bag and taped it to the window. In art we drew pictures of the water cycle and labeled the pictures in Hebrew on pixie. In Hebrew we studied the water cycle and played a game with cards. In science we also took a test on the water cycle.

Water Molecule Adventure Story

Photo on 1-20-15 at 3.19 PM There was a water droplet named Larry and he was on vacation traveling by aqua duct to the clouds. He was really cold and Larry was trying to get a job as snow. He got the job and formed a cloud with all his friends in the freezing sky. Then he fell from the freezing as a snowflake. Larry became rain again and stayed on the ground for the night in China Town.

BUTTERFLY JOURNAL

Madelyn was in charge of writing in our Butterfly Journal on DAY 11. This is her observation of the Larva/Butterflies.

I was excited when I finally got to write in the butterfly journal. They were in all in their cacoons when I had to observe them. Hopefully they will become butterflies soon! –Madelyn’s words, written by Ms. Tolisano

BUTTERFLY CYCLE

I found the background when I searched for butterflies. I like butterflies so this project was really fun. When the butterfly was a baby, it had a furry back. I was sad when we had to let the butterflies go into the wild. -Madelyn’s words, written by Ms. Tolisano
