Science: The Big Maglev (magnetically levitated) Train Race


The 4th grade students have been busily making magnetically levitated train cars in science. Balancing the magnets on a styrofoam block so that train car will levitate on a magnetic track is not easy. It was important to make their maglev train cars glide smoothly down the track. The challenge then was to make the car travel as far as possible from the end of the track.


The girls carefully taped magnets to the bottom of the styrofoam block.


They checked to see that their maglev train car balanced on the track.

What made the train car travel farther? The girls added pennies, sails, and/ or more magnets. Are you curious? Ask your 4th grade engineer what worked!

The big race!

Language Arts

The fourth grade is paddling further down the Negro River in Brazil where they have found the   Carter's house. Maia is realizing the beauty and the wonderment of the rain forest. Unfortunately, the twins are most unkind and uninviting, but Maia and Miss Minton, her governess, have found a way to circumvent their naughty behavior.

Our fourth graders are comparing how Maia, Miss Minton, and the Carters reacts to the jungle. Several of the girls have drawn a conclusion that the book seems a lot like a Cinderella story; the plot has a fairy-tale air to it.

In writing, we are concentrating on the parts of a sentence using the idea of "framing our thoughts." In other words, a picture frame is like a sentence because both have a subject and both usually have some kind of action, although "still" in a photograph. Once they have the idea of what the subject is we can use descriptive words, adjectives, to describe the subject, making it much more interesting.

Math

In math we are learning how to multiply 1-digit whole numbers by 3- and 4-digit numbers. Before we began the traditional multiplication using regrouping we used place value and partial products to find the products of multiplication problems. This lends itself to understanding the steps in doing a multi-step multiplication problem.

Moving On to South America





After several weeks visiting rural villages in Sierra Leone, Uganda, and Zambia, the fourth-graders are traveling to South America. Did you know that there was a difference in the number of continents depending on one's point-of-view? Some people in Europe see the Americas as one land mass or one continent, while we count North and South America as separate locations. 

What is your opinion? You can ask your daughter and start an interesting discussion.
