I often find myself doing homework at the last minute- how can I fix this?
Ah, procrastination, every student's worst nightmare. There is no one perfect solution for procrastination, you need to try out a few different ideas until you find the one that works for you. Here are a few ideas to help get you started: - Often, just starting is the hardest part! As soon as you get home from school, work on your homework for just 5 minutes. You don't need to work on it for any longer than that; if you feel like stopping after 5 minutes that is okay. You'll often find that after the first 5 minutes, doing the homework isn't as painful as you think! If you do take a break after 5 minutes, you'll be more familiar with the material when you look at it later! - Take breaks! No one can study for hours and hours straight and do their best work. Work for 20 minutes and take a 5-minute break. Repeat until your homework is done. If homework is less painful to do, you're less likely to avoid it! - Set smaller dates for yourself. If you have a big project due on Friday, break the assignment into smaller, more manageable chunks. Assign each chunk a different due date. It's often easier to accomplish small things one at a time than try to accomplish one big, daunting project all at once! There are many more ideas out there- feel free to ask me about them if these don't work for you!
Miguel has a lemonade stand. He spends 20 dollars on lemons, 4 dollars on cups, and 2 dollars on sugar. He sets up his stand on a hot, summer day and earns 71 dollars. How much money did he make overall?
To figure out how much money Miguel made overall, we need to find out how much he earn and subtract how much money he spent. We know he made 71 dollars overall, so now let's calculate how much he spent. The problem tells us he spent 20 on lemons, 4 dollars on cups, and 2 dollars on sugar. We can add those all up to find out how much he spent overall: 20 + 4 + 2 = 26 . Miguel spent 26 dollars on his lemonade stand. Migueal made 71 dollars but spent 26 to get it started. We can subtract how much he spent from how much he earned to figure out his overall earnings: 71 - 26 = 45. Miguel made 45 dollars overall on his lemonade stand!
How does the cell produce proteins?
Proteins are tiny molecular tools that our cells use to carry out their daily functions. The instructions for making proteins are stored in DNA as a series of base pairs. The base pairs of DNA are A, T, C, and G. Each protein is coded for by a long string of these letters. The information stored in DNA stays inside the nucleus of the cell, but proteins are made outside the nucleus in the cytoplasm of the cell. In order to get the information stored in the DNA out into the cytoplasm, a copy is made. This copy is called RNA. It is also a string of A, T, C, and Gs, but is an impermanent copy of the information found in DNA. Proteins in the cytoplasm called ribosomes "read" the code of A, T, C, and Gs and use that information to build a new protein! This transition of DNA to RNA to Protein is called the "Central Dogma of Biology", and understanding it is key to understanding how our own bodies work.
