End of 4th Grade Blog Post

In fourth grade I had a lot of fun. My amazing teacher, Mrs. Assatly taught me everything about math, reading, writing, social studies, science, and a lot more! We also had cool field trips such as, Wayside Cottage, Saint Paul’s Church, Westchester Philharmonic, Marble Schoolhouse, and kayaking. We also had other teachers that us things like spanish, art, physical education, music, and library. Fourth grade was a super special year.

 

In math this year we learned many things such as place value, geometry, fractions, decimals, order of operations, angles, symmetry, and area and perimeter.  My favorite math unit was decimals. Decimals are a fraction of a number. When we were learning about decimals we learned that there are different measurements for decimals. These measurements include tenths, hundredths, thousandths, and so on. Math this year was fun.

 

In social studies this year we learned many things. We learned about explorers, colonial times, and the Revolutionary War. My favorite unit in social studies was learning about the Revolutionary War. First we researched all about the Revolutionary War. Then we wrote an essay including all the information we researched about. Then we researched about a focus topic. A focus topic is a topic that we had to learn a lot about and really FOCUS on. Then we wrote an essay on our focus topic. Then we started to glue our essays in and illustrate our book. Then we wrote a historical fiction story. A historical fiction story is a story that isn’t completely true, because it’s part fiction, but you still add pieces of true information from history. After that we made a bibliography and an about the author. A bibliography is a list of sources you used to get your information. Finally, we completed our book and had a celebration for our hard work.

 

My favorite field trip was kayaking. I liked kayaking the best because I had never been kayaking before, and I love to try new things! During physical education, Coach S.W and Coach Felix taught us everything we needed to know about kayaking. In our first lesson, our class learned the different types of kayaks, and which type of water it was meant for. The different types of kayaks were white water kayaks, ocean touring kayaks, and recreational kayaks. We also learned how to put a PFD on. A PFD is short for personal flotation device. In our second lesson we learned how to get in and out of a kayak. In our third lesson we learned the different paddling strokes. Some strokes were forward stroke, reverse stroke, sweep stroke, reverse sweep stroke, and drag stroke. We also learned how to stop the kayak. In our fourth and final lesson before we hit the water, we had to learn how to capsize. Capsizing sounds scary, but it was actually quite fun. Finally we took the bus to the Scarsdale pool to test our kayaking skills. There were different stations for each kayak. We were paired up in groups, and we each took turns kayaking around the pool. When you were done taking about three laps around the pool you had to stop the kayak near your station, hand the paddle to your partners, and capsize. I personally think capsizing was fun and not scary. When you were done at your first station you could go to another. We also had a turn on the stand up paddleboard. Kayaking was really fun and I’m glad I got to do it!

 

In conclusion fourth grade was a blast! I’m really sad I have to leave my amazing teacher, Mrs. Assatly when I go to fifth grade. Although I am excited to be in the oldest grade in the whole school, I will miss my fourth grade classmates, teacher, senior option, Zach, and aid, Mrs. Ray. I had a lot of fun in fourth grade.

Can Alien Life Exist on Venus? Some Researchers Certainly Think So!

Can Alien Life Exist on Venus? Some Researchers Certainly Think So!

Summary:

In the article Can Alien Life Exist on Venus? Some Researchers Certainly Think So!, by Hannah Shariff, she explains how scientists may have discovered alien like life on the planet closest to us- Venus. For years, the journey to find life outside of Earth has spanned a “multitude” of galaxies. However, while breakthroughs like the discovery of liquid water on Mars and “Earth- like” exoplanets have raised hopes of alien life, the distance between them and Earth were too far, and made it hard to prove.

Venus was named for the ancient Roman goddess of love and beauty. Venus is the second planet from the sun and is similar in structure and size to Earth, complete with mountains, valleys, and tens of thousands of volcanoes. However, one difference between Earth and Venus is Venus’ thick atmosphere traps the sun’s heat, which makes Venus surface temperature an average 864 degrees Fahrenheit. That is hot enough to melt lead.

While these temperatures make Venus uninhabitable, American and Soviet probes were sent to observe Venus between 1962 and 1978. The probes discovered that the temperature and pressure conditions in some parts of Venus’ dense atmosphere may be “favorable” to some life forms. In 1967, American bioscientist Harold Morowitz and astronomer Carl Sagan noted that the “abundance of carbon dioxide and sunlight — the key ingredients for photosynthesis — in the clouds made it plausible that alien life could exist”.

Venus

 

A team recently led by University of Wisconsin- Madison scientist Sanjay Limaye, expanded upon this idea. They did this by taking a closer look at the mysterious, shape changing dark patches in Venus’ atmosphere. These mysterious, shape changing dark patches have confused scientists for many, many years. The team of researchers, who published their discoveries in the journal Astrobiology on March 30, say the particles making up the dark patches have the same “dimensions” as single celled, light emitting bacteria on Earth.

“On Earth, we know that life can thrive in very harsh environments, and can feed on carbon dioxide and produce sulphuric acid,” said Rakesh Mogul, professor of biological chemistry at California State Polytechnic University, Pomona, who co-authored the study. Mogul says since Venus’ acidic atmosphere also includes largely of carbon dioxide and water droplets which contain sulfuric acid, there is a high possibility of some sort of life form in the clouds. However, Mogul acknowledges, “To really know, we need to go there and sample the clouds.”

Algal Blooms

 

While NASA has their hands full with the 2030 mission to Mars, Russia’s Venera- D space mission, scheduled for the late 2020s, may allow researchers to get up close and see our closest planetary neighbor, personally. “Hopefully, Venus could be an exciting new chapter in astrobiology exploration,” Limaye said.

However, before you get up and about telling everyone that alien life exists on Venus, you should first know that scientists do not expect to find aliens like the ones described in science fiction movies. Instead, they believe the alien life forms will be something more similar to the algal blooms found in our lakes and oceans.
