High School Education Module
Sexual vs Asexual Plant propagation / Scientific Inquiry

This High School education module is a comprehensive science education module designed to compliment and supplement plant biology curriculums through scientific inquiry. This module consists of lessons directing students through the process of a scientific inquiry in two areas of agricultural science.

  • Seed germination in an inert / sterile growing media (sexual reproduction)
  • Plant propagation in an inert / sterile growing media (asexual/vegetative reproduction)

Students will apply the concepts, principles and processes of scientific inquiry within classroom investigations to:

  1. Apply technological designs to research tools necessary to perform scientific inquiries within the process of plant propagation
    1. Define plant propagation?
    2. What do plants need to survive?
    3. What tools are needed to scientifically perform plant propagation?

  2. Apply technological designs to research the concepts, principles and processes of scientific inquiries related to plant propagation processes
    1. What are the concepts, principles and processes of scientific inquiries?

  3. Conduct inquiries into growing media using technologies for research including collaboration of science professionals
    1. The term growing media refers to the soil, aggregate or substrate a plant is growing or grown in.
    2. What are the different types of growing media or rooting materials used in plant propagation?

  4. Develop a comprehensive understanding of sexual and asexual plant reproduction using technologies and science professionals
    1. Where do plant seeds come from? Type of plant?
    2. Where do plant cuttings come from? Type of plant?
    3. What are the genetic differences between plants that asexually reproduce and those that sexually reproduce?

  5. Develop a relationship between inert / sterile growing media and plant propagation
    1. What factors related to growing media have an effect on plant propagation?
    2. Compare and contrast researched growing media and factors related to plant propagation to develop a conclusion.

  6. Interpret research compiled regarding plant propagation to develop appropriate scientific questions
    1. Analyze all compiled data related to plant survival to develop four (4) questions pertaining to plant propagation to use as the beginning of the scientific inquiry. Use the attached KWL worksheet to assist in developing your questions.
    2. Record the scientific questions in the journal

  7. Formulate a content-specific hypothesis surrounding the developed scientific question for either sexual or asexual plant reproduction
    1. What are some guidelines in writing a hypothesis?
    2. Review the scientific questions written and then compose a content-specific hypothesis for one question to be answered.
    3. Record the content-specific hypothesis in the journal

  8. Determine variables and controls related to the materials and testing of the content-specific hypothesis keeping all safety measures and procedures in mind
    1. What are possible variables and controls to be considered in a scientific inquiry related to plant propagation?
    2. Variables and controls are things that can change.
    3. Analyze all variables and controls to determine the one (1) variable that matches the stated hypothesis
    4. Record this variable in the journal / or revisit your hypothesis if it needs to be more content-specific and then record
    5. Design the scientific investigation using all variables related to plant propagation and plant survival.

  9. Develop data recording processes relevant to the testing of the hypothesis
    1. Review various types of tables, graphs, charts or other recording devices that will allow data to be collected with all of the elements of the experiment included. More than one data recording processes may be used.
    2. Design your data recording device to ensure that your recordings related to the stated hypothesis.
    3. Create your data recording device. This will be included in the journal.

  10. Conduct a scientific investigation developed around plant propagation using researched technologies, soilless growing media and data recording processes related to the hypothesis
    1. Assemble all materials needed to conduct the scientific investigation
    2. Start investigation. Remember all variables are the same except the one (1) variable that is being tested for the hypothesis
    3. Record the complete procedure being used to begin the investigation. This is to be placed in the journal

  11. Compile data and test results from scientific investigation for analysis
    1. What are some methods or tools that can be used in the recording of the scientific investigations data?
    2. Record all data from the science investigation on a scheduled time frame. This data is placed in the recording device and then in the journal for future analysis.

  12. Design and present results in a scientific accord so that the conclusion proves or disproves the content specific hypothesis
    1. Once the specified time is completed for the investigation, design a presentation for the data collected. Create this presentation and include this in the journal.
    2. Develop a "Statement of Conclusion" which either proves or disproves the hypothesis. Record the "Statement of Conclusion" in the journal.

  13. Present the conclusion in a technological design that will promote further questioning, studying, inquiry and investigation
    1. Publish the journal, data recording devices, scientific questions, hypothesis, statement of conclusion and all other recorded documentation.
    2. Allow others to review your investigation and conclusion.

SteadyGROWpro is the ideal media for hydroponics and soilless growing. It is an inert and sterile growing media available in sheets, plugs, blocks and slabs.

SteadyGROWpro helps gardeners maximize results when germinating seeds, when propagating or cloning cuttings, and when growing plants to maturity indoors. SteadyGROWpro growth media is eco-friendly, and is a superior substitute to rockwool or coco coir.
