Aphid Control Activity
Students will research, select and test methods of aphid control in the green house. Note: Petro-chemical insecticides are not on the list of control methods.
- Guidelines for OHHS Lab reports. While we may not end up writing a lab report, all the aspects of communication found in a lab report are components of the experiment design process and presentation.
- OHHS Lab report rubric.
- Experiment design vocabulary.
- Informational Product with Visuals Rubric
- Blank Data Table
- A brief visual presentation to the class will include the following information:
- Does your question include what you will change (mv) and what will change (rv) when you do that?
- What do you already know about aphids and their relations with plants?
- What do you expect the answer is for the question? "If I do this (mv) , then this will happen (rv) because __________.
- Make a list of what you need to do this experiment.
- Do you have a step that tells a person what to change? (mv)
- Do you have a step that tells a person what to measure (rv) after they make the change you described above?
- Do you have a step that tells a person what to always keep the same? (controlled variables)
- Do you have a step that tells a person to write down the data?
- Do you have a step that tells a person how many times to do these steps over? (repeated trials)
- Check your procedure...does it make sense? Could anybody use this procedure to do the experiment?
- Does your data table include what you changed (mv) and what then happened (rv) ?
- Did you restate your hypothesis?
- So tell me, was the hypothesis or prediction correct?
- When you changed your variable (mv) the least, what happened (rv)?
- When you changed your variable (mv) the most, what happened (rv)?
- Put it together for me, what does the data say about your hypothesis?
- The Informational Product with Visuals Rubric will be used for grading. Use the OHHS Lab report rubric for insight as to the information requirements.
- Students may use a poster, Powerpoint , manga, or other methods shared with your instructor prior to committing.
