PLEASE HELP! ASAP!!!!

Lyndon is investigating whether putting plastic on her windows will help seal out cold winter drafts. She covers a window on the south side of her house with plastic and measures the inside temperature near the window. She also measures the inside temperature near a window without plastic on the north side of her house. The windows are the same size and design. Why is this not an ideal controlled investigation?

A.

The windows should be different sizes to introduce variation.

B.

The drafts at each window may be different because the windows aren’t near each other.

C.

Temperature isn’t a good indicator of cold winter drafts.

D.

Outside temperature is a better indicator of cold winter drafts than inside temperature.

E.

The type of plastic used in the investigation isn’t mentioned.

Answers

Answer 1
The answer should be B.

Prevailing winds are likely from the north.

Windward vs. leeward sides would create infiltration on one side and exfiltration on the other.

Should do a before and after on the same window under same conditions. Wind, ambient temperature, etc.

How should you set up your notes when using the Cornell method?

0 with levels and sublevels
0 with right and left sides
0 with tables and charts

Answers

Answer:

With right and left side charts

Explanation:

I was doing research on this exact question, so here is what I have been looking at;

The Cornell method uses a two-column approach. The left column takes up no more than a third of the page and is often referred to as the “cue” or “recall” column. The right column (about two-thirds of the page) is used for taking notes using any of the methods described above or a combination of them. After class or completing the reading, review your notes and write the key ideas and concepts or questions in the left column. You may also include a summary box at the bottom of the page, in which to write a summary of the class or reading in your own words.
