This should be the simplest part of raising monarchs, but sometimes unexpected issues can arise. You will find that the caterpillars like to congregate in corners when making chrysalises…sometimes, ominously close to one another. I have tried moving them to a different corner of the cage before they form their silk pupation pad, but many times they crawl right back. Cuttings or Plants Unfortunately, sometimes we make plans…and caterpillars laugh!

Discussion Conclusion In your results section you need to record your observations in a scientific way. You can do this using a table, diagrams or a combination of both. Think carefully about what information you need to record in order to come to conclusions at the end of your experiment.

In your discussion, you need to explain your results and what they mean. You also need to evaluate your investigation and explain if there were any unusual results and suggest ways that you could have improved your investigation for future researchers who might want to repeat what you have done.

Present your report on separate paper. This activity may be done in groups or individually. Up until now learners have been provided with a framework in which to write up their results. For this investigation, they need to compile their own reports.

Some examples of what learners might produce are included here: To find out which parts of variegated leaves photosynthesise and store starch.

The green parts of variegated leaves will turn blue-black in iodine solution indicating that they photosynthesise and store starch, whereas the white parts will not turn blue-black will stay brown. This should be a similar list to what was used in Part 1.

Learners must record the items in a bulleted list and take note of measurements. This should also be similar to Part 1. The steps in the method must be numbered.

They must be written in full sentences. Learners must take note of what measurements they used. Learners should draw a table to record their results. They should provide headings for the columns and rows and also a heading for the table. Learners must make drawings of their leaves at the start of the experiment, indicating the different coloured regions as boiling in alcohol will remove the colour.

They can then indicate the results on the drawings. Assess learners ability to explain their results. They should also make reference to the fact that the white parts of the leaves do not contain chlorophyll and therefore they do not photosynthesise. This also shows that chlorophyll is crucial for photosynthesis.

Learners should explain anything that they might have improved on in their results. This should be a short statement in which they answer their aim or investigative question. Leaves are not the only parts of plants that store starch. Starch is also stored in the stems, roots and fruit.

Have you ever wondered why fruit becomes sweeter as it ripens? Think of an unripe green banana and a ripe yellow banana. Which one is sweeter? Let's find out why. Why do bananas become sweeter as they ripen? It is not crucial to do this investigation if you do not have time.

This is an optional extension of the starch test. In this investigation we will taste the bananas to determine if they have more glucose or more starch.

We will also conduct a starch test on the ripe and unripe bananas to see which contain more starch. Ripe yellow bananas and unripe green bananas.

What do you wish to establish by conducting this investigation? Learner-dependent answer An example of a possible answer is: To investigate the presence of starch in ripe and unripe bananas; To investigate why bananas becomes sweeter as they ripen; etc. What do you think or predict will happen when you conduct this investigation?AFAM Intro to African American Studies This course provides an overview of African American history and culture.

Topics include major events, persons, and issues spanning the period from the African heritage to contemporary times. General Nutrition -.

The Carrot is an economically important horticultural crop that has gained popularity since world War Two (ended ) due to increased awareness of its nutritional value through the need to feed a nation at a time of great shortages.
