Quiz Tomorrow!

Tonight for HW, please write AND solve a ratio or proportion word problem.

Here's some practice with ratios and proportions.

Get your writing mind ready, you will be beginning your argument paper tomorrow in class.

Proportion Practice and The Height of the Moon's Features

Tonight for HW make sure to complete the proportion problems if they were assigned to you. In addition, please read The Height of the Moon's Features and answer the questions using proportions.

Mountains on the MOON

Please remind your parents that there will be a Jekyll Island Informational meeting will be FEBRUARY 2 AT 7PM IN THE MEDIA CENTER.
Tonight for HW, complete the word problems about the moon that should be glued into your EARTH journal.
1) The tallest mountain on the Earth is Mt. Everest which is 8848m tall. K2, which is 8611m tall, is also in the Himalayan mountains and considered a sister mountain to Mt. Everest. The tallest mountain (although not the highest point) on the moon is Mons Huygens at 4.7km tall. If Mons Huygens is the moon’s Mt. Everest, which lunar mountain is closest to the Moon’s K2, Mons Hadley at 4.6km tall or Mt. Bradley at 4.2km tall? Show your work

2) The highest point on the moon is on the far side (the side we don’t see). It is 6500m higher than Mons Huygens. Is the highest point on the moon higher than Mt. Everest? Show your work

Scale Drawing of SOMETHING

Remember, that you can choose to draw a scale drawing of any abject/space as long as you include:
1. The original measurements of the object/scale.
2. The scale that you have determined will allow the drawing to fit in your Earth Journal and any calculations you did to find that scale.
3. The scale drawing of the object.

If you having any questions about the Earth/Moon System for the parking lot, you can post them her.

Scale Drawing of Our Room

Create a scale drawing of the classroom, using the following information:
The room is 265 inches wide by 365 inches long.
The 6 tables in the room are 59 1/2 inches long by 29 1/2 inches wide.

Questions about the moon???

I hope that after our exploration of the size of the moon in relation to the Earth, that you are thinking of other questions about the moon. Here's on place to get some answers!

Quiz Tomorrow

For your quiz, you need to be able to write a ratio, solve for a missing number in a proportion, convert within the metric system, and measure things in metric or customary measurement system.
For HW, complete problems G, H, and L. For extra credit, you can complete I, J, and K.

More ratios and proportions.

I hope that you feel more confident about ratios and proportions after today. Remember, you only have to complete 10 of 20 problems tonight for HW tonight.

Ratios, conversions, and measurement. Oh my!

Tonight, please complete the measurement/conversion worksheet that we began in class today. Also, for extra credit you can complete Aid Memory as usual.

Metric Conversions

Tonight for HW you will be practicing converting within the metric system using proportions.
So, to solve the problem 8,000mL= _____________ kL, you begin with the known unit conversions given.
You know that 1kL = 1,000,000mL.
This will be one side of your proportion.
The other side you get from the problem.
Your proportion will look like this:

1 kL
_____

1,000,000 mL


=


x
__________

8,000 mL





Then, you cross multiply.

1 * 8,000=1,000,000x

Use your knowledge of 1-step equations and algebra.
First you need to isolate the variable using the inverse operation.
The operation in the problem is multiplication, so you will divide.

8,000/1,000,000=x
x= 0.008 kL

This answer makes sense because kL is a larger unit that mL, so the number should get smaller.

Pea-brained and Other Tiny Things

Welcome back! I hope that you had a restful and enjoyable break.... Now, back to WORK!
Today, we measured the volume of a cup in terms of peas. Tonight, I challenge you to find the volume of your brain in terms of peas.
Extension: How many peas would fit in a human brain?
To estimate the number of peas in a human brain using volume: calculate the volume of one pea by measuring the dimensions of the cup to estimate its volume (length x width x height) and then divide this number by the number of peas that fit in the cup. This is an estimate of the volume of one pea. Divide the average volume of a human brain (1,300 cm3) by the volume of one pea.

In addition, please complete the measurement practice.
