Learning Surveys & Final Chemistry Trials

6/12/2018

You started the day by completing several learning surveys. You reviewed your digital portfolios on FreshGrade and carefully completed your self-assessments. You self-assessed your work habits, attitude, strengths, stretches, self-regulation, and more. Reflecting on your learning is an integral part of the learning process. It is our hope that you can take what you learned about how you learn with you to high school in order to achieve even more success. We also did our final trials in the chemistry unit and have some solid data to work with. This data will help us answer our inquiry question of the relative strength of the acids and bases.

1) Reminders:

Keep getting ready for camp
Prepare and acknowledgment for someone at your table group

2) Math:

Complete the first 3 probability tree diagrams

3) Post A Response:

Part 1:

Prepare and acknowledgment for someone at your table group
Post who your acknowledgement is for on the website so no one is left our!
We will share the acknowledgments orally in class tomorrow! MAKE SURE NO ONE IS LEFT OUT!

Part 2:

Explain the difference between independent and dependent events in probability.
Use an example to help you explain

I'll acknowledge Andrew.
Independent events is an event or a thing that will never change
Dependant events are things that might change and don't follow a rule. They might double after once and twice after that.

An independent event is when it doesn’t depend on another event to get a lacerating outcome. A dependent event is hen it depends on the first outcome so that the second outcome can equal something.
Bad explanation?

Part 2:
An independent event is an event not effected by the outcome of the other events and will never change

Dependent events are events that are effected by other events and their outcomes.

An example to show an independent event: There is a bag with 1 red marble, 1 blue marble, and 1 yellow marble. What is the probability of you drawing a yellow marble?

An example to show a dependent event: There are 19 Pom poms in a bag. 10 are green, 2 are purple, 7 are pink. You draw one out, and it is pink. You set it on the table and draw another Pom Pom. What is the probsbility of you drawing a green Pom Pom from the second draw?

A independent event is on its own and not effected by other events before or after.
A dependent event is effected that can be effected by other events

In an independent event, the outcome does not effect any of the other outcomes in your "experiment". It has it's own results that don't effect any other results that you may get. Where as in a dependent event, the results effect other outcomes you receive. They all are put together.
(I will post the example in the morning when I have more time)

An example of an independent event is flipping a coin once. You will receive either heads or tails. When you have completed flipping the coin, the event is over. The outcome of what you got, is not effected by anything else.

An example of a dependent event, is if you had a spinner that was broken up into 4 quarters, red, blue, purple and green. I want to see out of 10 spins, which colour will the spinner land on the most. The first time I spin, it lands on blue. Now there are 9 spins left. The second time it lands on blue again! Then on the 3rd spin it landed on purple and so on...
This is a dependent event because all of the outcomes effected one another. They all added up together in the end to perform an answer.

(I think this is accurate? Correct me if I'm wrong)

Part 1:
I'll acknowledge Aaron.
Part 2:
An independent event is an event that remains the same each time and does not cause or is affected by previous and future events.
An example of this is a coin flip. If we have a coin and flip it over and over again, the first event's probability and outcome amount will be the same as the next one, and so on.

A dependent event is an event that is caused by the event preceding it. It does not and will not remain the same as other events; the probability and outcomes will change. Most of the time it can also affect other events too.
An example of this would be taking out items from a bag and not putting them back in. That way, the first event is independent, but the second and third ones depend on the ones preceding them, respectively. The probability and outcomes change with each event; the bag will have less and less items to choose from, and consequently, the probability of each item being selected will change.
If we have 4 marbles in a bag, the probability for each item being selected is 1/4. Once we take one out, the probability for each item changes to 1/3, and the amount of outcomes drops to three.

PART 2: An independent event is when that event isn't affected by events before or after it. A dependent event is something that is impacted by an event that comes before it.

An example:
Say you have a regular six-sided die. Rolling it multiple times would be independent events, the outcome of one roll doesn't impact the next one.
As for dependent events, say you have 10 cookies in a jar, five of them blue and five of them red. If you take one out, and eat it, that's an independent event, but taking another one out and eating it, that's a dependent event. Because you already ate one, the probability of you getting a cookie in a certain color is different, affected by the fact you already ate one.

Part 2.
A independent event is a event that isn't changed or affected by the events before it or after it and remains the same throughout the entire thing. For example a spinner. The first spins probability is the same as the second one and so on.

A dependent event is an event which the event after the first event is affected by the first event and doesn't remain the same throughout the events. A fine example is when you're drawing out the sticks for the seating arrangement. If you take out number 6 out of 28 then the next draw will be out of 27 and there would be no number 6.

An independent event is an event where it can't change the outcome like a coin toss. When you flip it once, it doesn't change the possibility when you flip it again.

A dependant event is when the first event changes the outcome of the events after. For example, there is a bag of 10 marbles, if you picked 1 marbles out of the bag, then when you pick it out again the possibility changes from out of 10 to out of 9.

An independent event is is when the first event is not affected by the other
An depedent event is the outcome of the first event which affects the outcome of the second

Kaya

Acknowledging Miikka!!

An independent event is an event that isn't affected by the outcomes of the preceding events. An example could be a coin flip. If the first flip is heads, this won't impact the result of the next flip; there are still only two outcomes.

A dependent event is an event in which the outcome of the previous events affect the outcome of the newest one. For example, drawing cards out of a deck. Say on your first draw, you pick a seven of diamonds out of 52. The next time you draw there will be 51 cards, so the probability of you choosing say a four of hearts is changed from 1/52 to 1/51

An independent event is when it doesn’t really matter what the outcome earlier was. Like when you flip a coin with an equal weight on each side.

A dependent event is when the previous outcome matters and will effect the outcome. Like flipping a bottle, if fail it will damage the bottle so you are less likely to land it.

I will be acknowledging Ray

Independent event:
An event in which the probability of something else happening is not effected by other outcomes. For example, flipping a coin and getting either heads or tails is an independent event because after you the second flip will not be affect by the first outcome and the third flip will not be affect by the second outcome and so on.

Dependant event:
An event in which other outcomes effect the probability of further outcomes. For example, you have a sock containing 10 different coloured peanuts. The probability of you getting a unique coloured peanut is 1/10. After the first outcome the probability will change to 1/9 now that a peanut has been removed. After the second outcome the probability will be 1/8 and so on.

I will acknowledge Hanyi.

An independent event in probability is when an event's outcome is not affected by the upcoming events. For example, flipping a coin. When you flip either heads or tails on the first flip, the second, third and so on is not affected by the first flip what so ever.

A Dependant event is when an event's outcome will be based on the future and past events. For example, there is a bag with 5 marbles of all different colours. The probability of picking a red marble is 1/5 but if you take out a marble, the rest of the outcomes will become 1/4 instead.

The difference between dependant and independent is that independent doesn’t change the event after the first event

Say you have 5 chocolate and u take out one. It wouldn’t be 1/5 anymore it would be 1/4
