The 5th graders worked this week on a skit about mathematical operations called, “Four Sisters”, the skit focuses on addition, subtraction, multiplication and division. It was a fun and educational play. We really enjoyed rehearsing and then presenting to each classroom in the school.
We watched and talked about some fun science/geography experiments this afternoon.
Mixing hydrochloric acid and ammonia shows that two liquids can make a gas.
Lead nitrate and potassium dichromate shows two liquids can make a solid.
Powdered sugar (carbon) and sulfuric acid makes a violent chemical reaction!
We didn’t get a picture of the last experiment, unfortunately. But we added heat to sulfur and ammonia dichromate creates a chemical reaction like a volcano.
The most interesting thing about the China: Shang Dynasty is that they had very fresh water for fishing and they built extremely high walls.
The one thing that really stood out about the Harrapa civilization is that they had excellent irrigation and plumbing systems.
Today and next week we will be blogging end of the year projects, be prepared for many interesting posts. Happy Summer!
Here is a great example of one of the many fun and interesting science experiments we did this year. The most interesting thing we discovered from this experiment was that ice is less dense than water.
The upper elementary class worked together on the school yearbook. They were able to use their photography skills, creative skills and organizational skills! The yearbooks turned out great and will be available for sale at our fun Spring Social on May 23rd. We included a some pictures as a preview. It was a fulfilling and fun project.
We made Wordles for our Mom’s for their Mother’s Day gifts, its a cool computer program that takes the words we entered, things we like about our mom, and turns it into a really cool picture incorporating those words. We also wrote letters and treated our Moms to a yogurt parfait bar. It was fun and we love and appreciate our Moms!
One day a man named Galileo was on the Leaning Tower of Pisa with two balls and they were the same size but one was heavier. Everyone assumed that the heavier ball would hit the ground faster, but when he dropped the balls they landed at the same time! This is called a free fall. In a free fall situation all objects will fall at the same rate of time. Air resistance plays a role- air resistance is when the objects are not the same size and the objects will fall and land at different rates. Think of a parachute.
So in the classroom, based on the ideas we learned from this story, we used a spark timer to conduct some experiments to measure terminal velocity. Terminal velocity is when an object reaches a consistent speed and does not change.
Pictured here is the tape showing the marks made by the spark timer. The closer the dots, the slower the speed. Our object started slower but eventually the dots get farther apart, showing speed. When the dots are the same distance apart, that indicates the object reached its terminal velocity and did not speed up any more.
For Spanish, the elementary got to have a big Cinco de Mayo party! Our Spanish teacher Miss Jenna planed such a fun afternoon with dancing, playing games, learning about Mexican history, and even making gods eyes. People got so inspired they even went home and made really big gods eyes! It was so fun and we all learned a lot.
