Studying Levers



In science we have been studying about forces and using levers. We learned about forces which are a push or a pull. An example of a force is flipping a page in our textbook. Another example is pushing a chair in and out.

We did an experiment with levers. We took three pencils and taped them together in a triangle shape. Then we had a ruler that we taped two cups to either end. We laid the ruler sideways across the pencils. Then we put two big marbles into one cup, and we put many other little marbles in the other cup to see how many it took to tip the cup that way.

We also learned about fulcrums. A fulcrum is where the ruler touches the pencils. In my experiement with my group, we put the fulcrum in the middle first, and then we put it at three inches. The middle fulcrum took nine marbles to tip the cup. When the fulcrum is closer to the big marbles, it takes less marbles to tip the cup. When the fulcrum is close to the little marbles, it takes a lot of marbles to tip the cup.

I liked doing the project that we did because it was a fun way to learn about science and fulcrums and levers.

Benjamin Franklin



We have been learning about Benjamin Franklin in our reading book. Benjamin Franklin was born in Boston in 1706. He was the tenth child in his family. His mom had seventeen children.

When Benjamin was twelve he went with his brother James to work at a printing press. When he was seventeen he left Boston and his brother to go to Philadelphia.
A few years later he married a woman named Deborah Read and owned a print shop.

They had three children. William was the oldest, Francis died when he was four, and Sarah was called Sally by her father.

Benjaman wrote Poor Richard's Almanac. Benjamin discovered that lightning is electricity. Benjaman Franklin went to England to go ask the king for independence for the country. Eighteen years later he came back to the colonies, but he was sad because his wife died.

Benjamin Franklin was one of the signers of the Declaration of Independence. He worked hard to get freedom for America.

Mexico City's History



In Social Studies we are learning about the history of Mexico City. Seven hundred
years ago in the place of Mexico City, a city named Tenochtitlan was built
on Lake Texcoco. The Aztec Indians built their city on Lake Texcoco after they saw an eagle sitting on a cactus with a snake in its mouth. They thought it was a
sign from their gods.

After they built the city, the Spanish came and fought the Aztec Indians. The Spanish destroyed Tenochtitlan. The Spanish drained the lake in the 1600s. The Spanish named their new city Mexico City.

Then the Mexicans took over Mexico City because they formed their own government. Today, Mexico City is a part of the country of Mexico. Mexico City is the largest city in the world with a population of 21 million people.

One problem with Mexico City is the pollution. Pollution is anything that makes the air, land, or water unclean. The city leaders are trying to fix the pollution by building subways and having days where they don't drive cars.

An interesting fact is they built a museum in the subway. They did this because they found pieces of Tenochtitlan buried underground when they were building the subway.

Preparing for Visitors

We have spent many weeks preparing for WASC. We have done a lot of art. We have colored shamrocks and they came out good. We have leaned how to work together in groups. Our class has worked on St.Patrick's day art and decorations. We colored St. Nicholas pictures.


Stephen works hard on a Lenten assignment.


Isaiah figures out what to do next for his rainbow/shamrock writing project.


We are looking forward to our visitors and want them to see all that we do.
