Finding My Volume!

Volume of Liquids

Volume is the amount of space something takes up. Volume of liquids means the amount of space a liquid takes up, and it is measured in liters (L). Smaller volumes are measured in milliliters (mL). To find volume of liquids you use a graduated cylinder and read the bottom of the meniscus. The meniscus is the bubble that forms at the top of a column of water. It is important to make sure you look at the cylinder and determine how much each graduate is worth before you make a reading.

1,000 Lockers Explanation

Question :

The problem involves many things that we have learned in class including multiples, factors, and square numbers. The question is that if student 1 opens all 1,000 lockers, student 2 changes the state of all lockers that are multiples of 2, and student 3 changes all multiples of 3, etc., which lockers would be open?

Explanation :

First, we discovered that all prime numbers would be closed and in doing so, that narrowed it down. Then, we tried to find out which ones were open in 30 lockers because we didn’t see how the prime number helped that much, but we decided against it because we knew the pattern wouldn’t repeat. So after that, we went back to the prime numbers because it was the only thing we had. We started to think about it factor-wise. Why were all prime lockers closed? Because they all had an even amount of factors (2). That means all numbers with an odd amount of factors would be open, the problem was finding every number with in 1,000 with odd factors. We then recalled having a lesson about square numbers and them all having odd amounts of factor because one of their factors multiplied by itself was that number. That means every square number would be open. Every square number is open because they have an odd amount of factors, but why? That is because all square numbers have one factor pair where there are 2 of the same number so we only count it as one factor and therefore all square numbers have an odd amount of factors. Of course that is just generalization, we also want to find out how many lockers there were. We needed to find out how many square numbers were in a thousand. Now all square numbers are not in 1,000, so we just needed to find which square number goes over a thousand. I tried 50 * 50 first and it was way over a thousand, so I tried halving it (25 * 25) but it was too small. So I tried 30 * 30 and it was just a little too small. So then I tried 31 * 31 and it still fit 1,000 but I didn’t know if the next square number (32 * 32) fit in 1,000. It turns out that it doesn’t. So there are 31 square numbers in 1,000 and that means 31 of the 1,000 lockers would be open.

Representations :

Out of 30 :       O = OPEN       C = CLOSED       BOLD = SQUARE      UNDERLINE = PRIME

1 - O	2 - OC	3 - OC	4 - OCO	5 - OC	6 - OCOC
7 - OC	8 - OCOC	9 - OCO	10 - OCOC	11 - OC	12 - OCOCOC
13 - OC	14 - OCOC	15 - OCOC	16 - OCOCO	17 - OC	18 - OCOCOC
19 - OC	20 - OCOCOC	21 - OCOC	22 - OCOC	23 - OC	24 - OCOCOCOC
25 - OCO	26 - OCOC	27 - OCOC	28 - OCOCOC	29 - OC	30 - OCOCOCOC

Square Numbers :

50 * 50 = 2,500  Too Large

25 * 25 = 625  Too Small (Could be a Bigger One)

30 * 30 = 900 A Little Too Small (Maybe One or Two More still Bigger)

√√√  31 * 31 = 961 (There could be a bigger one) √√√

32 * 32 = 1024 Too Large  (This means 31 is the biggest and is correct)

Swimming Reflection

1. Describe what you do well with your freestyle stroke and what you can improve on.

I did good with my head turn, flutter kick, and arms in opposition but I need to have a long reach.

2. Describe how perseverance is relevant to the biathlon. Explain how you demonstrated this.

Perseverance is needed in the biathlon because if you give up half way through, then you won't be able to go to your full potential and will get a bad time even though you could have gotten better.

I demonstrated this when I was running on the track. I am not a very good runner but I paced and encouraged myself to keep going and try not to stop for a walk, and I didn't!

I am at 3:30

Drama!!!!!!!!!!!!! 7.5!!!!!!!!!!

TEN is a person who is dying to hit the stage on day one of drama and would willingly perform in front of all of 6th grade right NOW!  ONE is a person who would rather be ANYWHERE but the stage and would prefer to be wrapped up in a blanket back in their bed hugging their teddy bear. On this scale of one to ten, I would be a 7.5 because even though I have done some plays I wouldn't want to get up on stage right now. I also don't like to preform in front of A LOT of people. I like acting but I'm not comfortable acting on the spot in front of a crowd. I would prefer practicing and also not in front of too many people.
