CHEMISTRY – Wow! Do you realize what we just did?!? We finished the chapter!!! Did you feel like today was mostly review?
There are three elements that you will research for the test – Cu, Si, and P. A great resource to research the elements (and the only one you need besides the textbook) are these video clips on copper, phosphorus, and silicon that a group of chemistry researchers have put together at www.periodicvideos.com. Watch these and take notes. The information on these video clips will be on the test.. If you can’t get the phosphorus video to work, use this link on YouTube https://youtu.be/LSYLUat03A4
Hey, have you had a chance to check out the chapter 1 study suggestion sheet? Let me know if there is anything you need help with before the test! (And you’re still learning the symbols of the elements, right?!?)
🙂
This week, I researched the way different patterns of clear ink can produce beautiful pictures! The patterns in the ink on the surface creates different colors because light bounces off the designs. Wavelengths can be changed when adjusting the microdomes in printers, changing the colors too. Scientists have already created portraits with the cool patterns. Maybe the patterns will even be used in makeup or architecture!

This week I learned about how artic sponges eat dead ecosystems to survive. While most sponges are filter feeders, these article sponges live so deep in the ocean that they cannot get food from any current because there aren’t any. The scientists researched what was underneath the sponges and found that there were many disregard spicules and things like empty worm tubes. This underneath layer is about 15 centimeters thick in some places of the mat. With this knowledge, scientists say that if, on average, in some places, it was 4cm, that means that it will provide carbon 5 times, the sponges need to survive.

I researched a recent study that found honeybees read numbers from left to right. A new study shows honeybees will fly left when given the smaller of two side by side numbers and to the right with the larger number. The importance of this study is that it is beloved humans have an innate mental number line not a learned one. This study gives good evidence that honeybees do as well.

This week I researched how some fungi produce toxic chemicals called mycotoxins these toxins spoil foods like grain and also have the ability to make us sick. Some may even cause liver cancer and other serious health problems.

I researched how U.S rivers are on the rise of getting hotter. Researchers have been getting data for U.S rivers across the United States and it shows how from 1996 to 2021 the average number of heat wave rays river went from 11 to 25 a team in Limnology and Oceanography Letters reported. The factor that plays a big role of this increase is human—cause global warming. That’s not only thing it’s also less precipitation and lower water volume. But the big reason why this a problem because it’s effect water life and plants. Some animals in the water can’t take being in hot temperatures which can cause them to die. Actions will be made in order to protect and save the sea environment.

This week I researched on the harmful effects on relying on groundwater for farming as it can affect the amount of surface water. The amount of groundwater used for other expenditures will directly result in most watersheds reaching their tipping points by 2050, which means that if farmers pump too much ground water, the availability of water is slowly decreasing as a result. This study is displaying awareness of the diminishing access of water in the future.

This week I researched about how there are stove tops in California that are leaking gases that can give you cancer. Out of the 159 homes scientist tested, all of them had some sort of harmful gas that was being released.

During the Black Plague time era scientist were able to find that people who possessed a variant of a gene ERAP2 were sparred more then the ones without the gene. Scientist were able to prove that this gene improved the odds of the people surviving by 40 percent.

Today I researched how for the first time scientist have found that the dust in space is pushed around by starlight. The radiation pressure from these healthy stars pushes the dust towards and around dying stars. These events have allowed scientists to further understand the solar system and how it works.

This week i researched that wild fire smoke is very dangerous because of the aerosols in it. They say children are at a very high risk if they inhale this it could go deeply into their lungs because it is 1/30th the size of oxygen.

So I researched this girl my age who uses air-compressing pipes to shoot bubbles up toward the river’s surface. The bubbles stretched diagonally across the river, catching the plastic and pushing it into a dumpster, letting animals and water go through. It was so interesting! I’m so inspired to attempt something like that because if a lot of people do small things that help the planet, we’ll eventually help it.

How many elements did the first periodic table have? From my research, the first periodic table by Mendeleev only had 63 elements on it, this was because at his time only 63 had been discovered.
Scientists recently discovered that as a swarm of honeybees are flying around, they are creating an electric charge. When they started observing larger swarms of insects, they discovered that a swarm of locusts can create an electric charge almost equal to that of storm clouds.
