BES: Research design plans April 18, 2019 Please obtain the yellow handout. Get your rubric and Individual Plan out.

Community Building! Give the person across from you a triple fist bump! Ask that person “What is your opinion of putting ketchup on macaroni and cheese? Yeah or Neh?”

Warm Up 4-18-19 What does it mean to be a phytoremediation plant?

Designing a Phytoremediation Experiment: Your Research Design Plan

What is phytoremediation? Here’s another example of phytoremediation. Video link

Why are Peer Reviews necessary? They do it in the “real” world all the time! Peer Review Video clip

Experiment Constraints: Unit Project: Design an experiment to study phytoremediation in Fast Plants Experiment Constraints: Zinc and copper are the “toxins” you can use. Suggested amounts to test are: Copper: 0, 50, 100, 200, 400 mg/liter of H2O Zinc: 0, 25, 50, 100, 300 mg/liter of H2O  You have 3 different species of Fast Plants (Brassica) to work with. You can use the Brassica plants you grew, or Brassica seeds: Brassica negra Brassica juncea Brassica rapa NOTE: To more easily manage the disposal of the toxins used and to more accurately mimic soil contamination by heavy metals, the students should add the toxins to the soil, not to the water tray. ©2018 Educurious Partners.

Brainstorm in your Journal What kinds of questions can we ask about Fast Plants (Brassica) and phytoremediation? Does pH affect how Fast Plants can absorb toxins? What kind of toxins can Brassicas absorb. What amounts of toxins or heavy metals can Brassicas absorb. How do metals affect the plant? Do the toxins stay in the plant? What should we do with the plant after it has absorbed the toxins? Explain to students: Note: For your experiment, due to time and cost, you cannot measure the amount of heavy metals your plants do or do not take up. However, you can design your experiment to see what conditions help these plants thrive or not—telling you if they would be a good plant to use for phytoremediation.   Is this clear enough without giving too much away? ©2018 Educurious Partners.

Introduction to Research Design Unit Project Why do scientists need to plan out their experiments BEFORE they do them? What is the variable I’m going to change? What is my control (the thing I’m going to compare to)? How will I set up my experiment? What materials will I need? How many trials will I complete? What do I know about the topic? Is there a local issue with this topic? Who will it affect? ©2018 Educurious Partners. All rights reserved. www.educurious.org

Research Design Plan Project Overview Grade example research design plan using rubric. Write individual draft research design plan. (Turn in) Peer review individual research design plans. (With comments and use rubric) With your team, decide on a research design plan. Write first draft of team research design plan with your team (individually) Submit team research design plan for Ms. Jarvis’ review. Revise research design plan based on feedback. ©2018 Educurious Partners. All rights reserved. www.educurious.org
