First Look Venus has a thick, poisonous atmosphere filled with carbon dioxide and wrapped in yellowish clouds, mostly made out of sulfuric acid. Sulfuric acid traps heat and blocks thermal radiation, preventing the planet from cooling and having water on its surface. This is called a runaway greenhouse gas effect. It's caused when a planet's atmosphere contains enough greenhouse gas to block thermal radiation. Spacecraft Venus is also the first planet to be explored by a spacecraft. On December 14, 1962, NASA's Mariner 2 passed by and scanned the gaseous world. After the discovery, numerous spacecraft and space agencies explored Venus. One example, like NASA's Magellan, mapped the planet's surface with radar. The only nation to land on Venus is the Soviet Union, but the spacecraft did not survive long in the brutal environment. Venus: The hottest planet in the Solar System Venus is the second closest planet to the Sun, so you would probably think that it would be the ...
How to solve basic algebraic equations with the properties of equality: Multiplication and Division
When you see the equation you'd probably know what the answer is. But the real question is, do you know how to show how you got your answer? Remember: Our goal is to get y on one side and numbers and operations on the others. Let's look at the equation. We need to get rid of ÷3 and one way to get rid of it is by doing the inverse operation, multiplication! y÷3=4 ×m So since we multiplied 3, we have moved y to one side and removed ÷3. But, we still have to do one more thing. Do you remember the math rule with equations and expressions? We have to also multiply the 3 to 4! y÷3=4 ×m ×m We have now gotten y on one side, removed ÷3 by multiplying 3 itself, and did the same to 4. In summary, our equation has now simplified into y=12. Let's plugin our answer into the equation! 12÷3=4 Yup! Our answer is correct. We can check by multiplying 3 and 4, which does equal 12. Make sure to always plugin your answer and check! Now that you solved a division ...
How to solve basic algebraic equations with the properties of equality: Addition and Subtraction
When you first see x-4=8, you might instantly know the answer. But do you know how to show how you got your answer? Let's look at the equation. We want to have x on one side and all the other numbers and operations on the other side. Now, this may sound a little confusing, so I'll explain further. We want to get rid of the -4 in x-4=8 so that we can immediately have our answer, x= something. We can't have -4 in the way because x-4=8 is not giving us the answer. So in order to get rid of the -4, we have to use the inverse operation, addition. x-4=8 +4 Now, if we add +4 to the equation, we have x=8. This answer is obviously not correct, for 8-4 does not equal 8. The reason the answer is not correct is because we have not added +4 to 8. Why do we have to add +4 to 8? There is a rule when dealing with equation. Whatever you do on one side, you also have to do on the opposite side. So in this case, we have to add 4 to 8 because we have added 4 to -4. x-4=8 ...
Algebraic Expressions
You may have heard of a numerical expression, but have you heard of a algebraic expression? Numerical and algebraic expressions both have numbers and operations, but algebraic expressions include one more thing, variables. Variables are numbers that are written down as a symbol. You probably heard of x, y, a, c, and etcetera, which are all letters from the alphabet. Variables do not have to be letters, although they are more common. A star could also be a variable. These letters are used a placeholder for varying expressions and quantities, which is why they are called a variable. A algebraic has at least one or more variables. IMPORTANT: Keep in mind that both numerical and algebraic equations DO NOT have equal signs. When a group of numbers and operations do have a equal sign, they are called a equation. Now, let's test your knowledge before we get on to the more complicated information. What type of expression is this? 2+4+1 1. ...
The Periodic Table
"The periodic table is important because it is organized to provide a great deal of information about elements and how they relate to one another in one easy-to-use reference. The table can be used to predict the properties of elements, even those that have not yet been discovered."- Google Since there is 118 elements and still more to come, I recommend you get ready for... A LOT of writing. Here are the elements of the year 2020. P.S.

Categorized Conjunctions
Conjunctions are words or short sentences that connect sentences or clauses. Instead of using and and but, use these conjunctions instead! They are separated in time, equality, contrasting, conditioning, and cause and effect! (And sorry, this list is long and horizontal so it's hard to read everything. I was trying to make it landscape so it was easier to see, but I have no idea how to LOL.) Enjoy!

Water Cycle
Learn about evaporation, condensation, sublimation, precipitation, transpiration, runoff, infiltration, and collections! Evaporation, the process by which an element or compound transitions into a gaseous state below the temperature at which it boils. To be more clear, the process by which liquid water enters the atmosphere as water vapor. Condensation is when the water vapor starts to become liquid form by being in contact with other water vapors. Sublimation is when a solid turns into a gas, passing the liquid stage. For example, dried ice, a solid, turns into a gas right away if you put it in water. Precipitation is the falling products in the atmosphere like snow, hail, or rain. When the clouds from the condensation combine with too many other water vapors, it starts to come down, causing rain and etc. Transpiration is the water vapor through plants. Since plants need water, the plants transfer the water through plant tissues and release the water vapor through their ...
Black Holes: How do black holes collect energy? How does it suck you in? How can we use the Black hole as an energy source?
Written by: Ryan L. Edited by: Shannon Y. INTRODUCTION Black holes are a collection of massive amounts of violent energy in the universe. If something gets close to the black hole, it will devour it, adding your energy to the black hole’s collection. So how are black holes created? It all happens when a massive star or sun dies. Its core will collapse on its own gravity making a black hole. How do Black holes collect energy? To understand how Black holes collect energy, it takes a very complex idea. But we can summarize it down, so you can easily understand. Basically, black holes collect energy when stars are spinning, and also when other things that are spinning don’t want to stop spinning. This is called angular momentum and this angular momentum can’t go away. When a big thing gets smaller, it spins faster. So as the core of the sun collapses, it spins faster. Yes, the black hole is actually spinning. Now how does it suck things? Just imagine a black hole as ...
Charles Darwin
Charles Darwin was born on February 12, 1809 in Shrewsbury, Shropshire England. His parents were Robert and Susannah Darwin. At the age of eight, Susannah passed away from stomach cancer or a severe ulcer. Robert Darwin was a medical doctor and Susannah was a physician. Charles's dad wanted Charles to be a doctor, so he transferred him to Edinburgh University from Anglican Shrewsbury School. He gave up medical school after two years, not being able to stand blood or surgery. Then he went to Cambridge University to study theology, the study of the nature of God and religious beliefs. In 1831, one of his Cambridge professors recommended Charles as a naturalist and companion for Robert FitzRoy on the boat HMS Beagle. Charles immediately accepted and went exploring with the crew. He went to a variety of regions and continents, including the Galapagos Island. He is famous for studying small creatures, finches. Finches are a type of bird that are usually red and orange ...
