Looks OK.

Bit of a shame that you didn't set a checkpoint before rewriting Brad's text.

This was originally "watching grass grow". I have changed the context from 1st to 3rd person and changed grass to a sunflower, which seems a much more likely thing to measure.

Also used the random names extension, and as a result I've changed quite a lot of this, so I'm marking needs to be tested.

Published this.

Lovely question, definitely one of my favourite questions so far. Just a few grammatical comments

In the statement you probably should put a hyphen between observation and B as you have for "Observation-A"

Main Parts

a) good (the graph looks really nice)

b) I would delete the should in the question here

In the first (top left) bullet point, "take" should be "taken"

In the bottom left bullet point, you could change "millimeters" to just mm if you wanted.

c) you write "3^th day" but this should be "3^rd day"

I don't think you need a colon at the end, i would just put a full stop

e) "The power goes to you head" should be "The power goes to your head".

I would put a "why" after hence and before "this".

a) I would put the equation to calculate c in the second paragraph on it's own line using display mode.

"point's" should be "points"

I would put the multiplications in brackets here.

c) i don't think you need the colon here

d) Again i don't think you need the colon here.

e) "oustide" should be "outside"

Hopefully this question will inspire many young students to become grass length consultants in the future!

This variable is an HTML node. HTML nodes can not be relied upon to work correctly when resuming a session - for example, attached event callbacks will be lost, and mathematical notation will likely also break.

If this causes problems, try to create HTML nodes where you use them in content areas, instead of storing them in variables.

Describe what this variable represents, and list any assumptions made about its value.

#### Error in variable testing condition

There's an error in the condition you specified in the Variable testing tab. Variable values can't be generated until it's fixed.

No parts have been defined in this question.

Select a part to edit.

Ask the student a question, and give any hints about how they should answer this part.

The correct answer is an equation. Use the accuracy tab to generate variable values satisfying this equation so it can be marked accurately.

#### Checking accuracy

Define the range of points over which the student's answer will be compared with the correct answer, and the method used to compare them.

#### Variable value generators

Give expressions which produce values for each of the variables in the expected answer. Leave blank to pick a random value from the range defined above, following the inferred type of the variable.

#### String restrictions

Both choices and answers must be defined for this part.

##### Base marking algorithm

#### Test that the marking algorithm works

Check that the marking algorithm works with different sets of variables and student answers using the interface below.

Create unit tests to save expected results and to document how the algorithm should work.

There's an error which means the marking algorithm can't run:

#### Unit tests

No unit tests have been defined. Enter an answer above, select one or more notes, and click the "Create a unit test" button.

The following tests check that the question is behaving as desired.

### This test has not been run yet This test produces the expected output This test does not produce the expected output

This test is not currently producing the expected result. Fix the marking algorithm to produce the expected results detailed below or, if this test is out of date, update the test to accept the current values.

One or more notes in this test are no longer defined. If these notes are no longer needed, you should delete this test.

When you need to change the way this part works beyond the available options, you can write JavaScript code to be executed at the times described below.

Run this script the built-in script.

This script runs after the built-in script.

To account for errors made by the student in earlier calculations, replace question variables with answers to earlier parts.

In order to create a variable replacement, you must define at least one variable and one other part.

Variable Answer to use Must be answered?

The variable replacements you've chosen will cause the following variables to be regenerated each time the student submits an answer to this part:

These variables have some random elements, which means they're not guaranteed to have the same value each time the student submits an answer. You should define new variables to store the random elements, so that they remain the same each time this part is marked.
