INTRODUCTION:
Soon after the Brassia oleracea plants were transferred into the garden, nearly all of the crops have died. There are many potential causes as to why they could have died.
THE QUESTION:
What could have caused the sudden death of the crops? There is one suspect and that is the insects, insects tend to feed on food such as cabbage, broccoli, and mant more because those are easiest to eat. The answer to this is not pesticide, but a task that requires a bit more work which is doing check ups on plants.
BACKGROUND
Crop failure is a fairly common thing with farmers. If avoided by doing the right steps, healthy plants could grow. If the plants aren't checked on very often, they will be vulnerable to consequences like diseases, insects, and animals and make the farmer lose money and people starve.
THE PURPOSE:
When beginning the investigation, my team and i noticed that there were signs of bite marks on the affected crops. There also seemed to be a few insects such as caterpillars and insects.
THE MATERIALS:
What my team used were specimen jars, paper towels, a few rubber bands, leafy vegetables, and catterpillars. My team got help from classmates from another period that had a similar experiment to ours.
HYPOTHESIS
My team believes that insects are the major cause of the sudden death of the crops. The amount of leaves being eaten depends on the caterpillars. The catterpilars are in no way impacted negatively, but the plants are. We chose this as our hypothesis because of the presence of insects on the garden and because of the bite marks on the crops.
SUMMARY
The results of the experiment were not too much to support the hypothesis. After some time, the caterpillars started to go into miosis. This also happened to the other team in 4th period. But, the other insects that were caught did eat the leaves.
