Which sentence is the claim?
Air is matter.
We found that the weight of the ball increases by .5lbs each time we pumped more air into it.
This shows that air has weight, one of the characteristics of matter.
Which sentence is the evidence?

We found that the weight of the ball increases by .5lbs each time we pumped more air into it.
This shows that air has weight, one of the characteristics of matter.
Which sentence is the reasoning?

Which of these is relevant evidence to this claim: Plants in bigger pots will grow taller.
The researchers placed plants in pots of different sizes and let them grow for one month.
Some plants grow taller than others when grown in large pots.
According to the data, a plant grown in a 5 cm pot only grew to be 4 cm tall, where as a plant in a 10cm pot grow to be 8 cm tall.
The researchers observed 10 plants total, 5 planted in smaller pots and 5 planted in larger pots.
Which reasoning explains the following evidence? "According to the data, a plant grown in a 5 cm pot only grew to be 4 cm tall, where as a plant in a 10cm pot grow to be 8 cm tall."
When plants are placed in a bigger pot, the roots have more room to spread out, making it more optimal for a plant to grow taller.
Sometimes, plants just enjoy being in a bigger pot. When a plant enjoys its pot more it will grow taller
No one really knows why, it just happened.
The evidence supports the claim that plants grow taller in a bigger pot because a plant grown in a 5 cm pot only grew to be 4 cm tall, where as a plant in a 10cm pot grow to be 8 cm tall.
Which options provide relevant evidence to support the claim that students who get less sleep are more likely to perform poorly in academics. (Select up to two)
According to the study, students who went to sleep later, causing them to get less sleep, scored an average of 30% lower on their exams.
The claim of an article I read in another class was that students who sleep less do poorly on tests.
Students reported feeling more sluggish over all, making it hard to focus and do well on their exams.
According the the study, the kids were sleepy. When I am sleepy, I also do poorly on my assignments.
Which reasoning explains the following evidence? "According to the study, students who went to sleep later, causing them to get less sleep, scored an average of 30% lower on their exams."
When a person has had less sleep they can have a harder time remembering things, focusing, and reading. All of these can result in mistakes on an exam which could explain the lower score.
When a person has had less sleep they are often in a bad mood. Exams also put people in a bad mood.
I got an A on my last history test after studying all night, so maybe they did the experiment with people who are bad at studying?
The evidence supports the claim that people who get less sleep do poorly on exams because students who went to sleep later, causing them to get less sleep, scored an average of 30% lower.
If the prompt is, "Is there a best color notebook to use for your science class?", which of the following would make a good claim?
Yes, there is a best color but I'm not telling.
There is no single "correct" color to use for a science notebook.
There is only one correct color to use as a notebook for any subject.
I have always used purple notebooks for science class.
If the prompt is, "Do students who sleep get better grades?
No, students who sleep do not study.
Students who are well rested are likely to be able to focus, remember information, and participate in class.
I will test this by sleeping in class.
Yes, I think so.

If you were graphing this table on a grid that had 10 available spaces horizontally and vertically which of the following options would make the easiest to read and most accurate graph?
every horizontal space is worth 4.5 hours. Every vertical space is worth $0.5
every horizontal space is worth 1 hours. Every vertical space is worth $36
every horizontal space is worth 5 hours. Every vertical space is worth $10
every horizontal space is worth 0.5 hours. Every vertical space is worth $4.5
If you were to graph this data set and your graph had 10 vertical lines to place your data on, how much would each line need to be worth to get an easy to read graph?
Each line should always be worth 1 and I can use a ruler to extend the graph space.
If I count by twos it will be easy to estimate the odd numbers half way between lines and I'll have enough space.
I can place 3 on the first line, 8 on the second, 11 on the third, 8 again on the fourth. I'll only need 6 of the lines.
The first number is 3 so I should count by 3s.
