Preparing for this Lesson
Indoor Air Quality
Preparing for this lesson / This lesson assumes that an Extension educator will be the speaker. If an alternate facilitator or co-facilitator is used, be certain they have reviewed the material and are clear that Extension is tasked with presenting non-biased material.
Before the training:
  1. Several weeks in advance:
  • Determine appropriate training location and time
  • Contact guest speaker(s) at least a month in advance (optional)—if using, use Guest Speaker Confirmation form. For this subject area, consider asking a radon professional or fire department representative (discuss CO poisoning), for example
  • Send out notices for the training
  • Order handouts/reference materials/videos
  1. At least one week before training:
  2. Read the lesson guide and PowerPoint materials; review speaker notes and add notes if necessary
  • Review handouts/reference materials and supplemental material
  • Make copies of handouts
  • Review the optional activities and assemble show and tell activity/demonstration tools. Visit a store and purchase demonstration supplies or bring samples from home. See Suggested Materials & Supplies for Demonstrations and Activities.
  • Download any videos onto your computer
  1. Day before training:
  2. Assemble snacks/beverages: Drinks, fruit, plates, napkins, etc.
  3. Load course materials on computer/thumb drive
  1. Day of training
  2. Arrive at least 45 minutes in advance
  3. Set up computer/LCD projector/check speakers. Tape down cords.
  4. Set out references/publications, course materials. Either place on participants’ tables or place near registration table for students to pick up. Set out registration sign-in list
  5. Set up demonstration tools on table or have in container for easy access
  6. Set up whiteboard/large flipchart

Presenting the Lesson
Indoor Air Quality
Important Instructor
Notes /
  • Remember to use activities, demonstration of materials, and videos for a variety of teaching tools and to not be too dependent on the PowerPoint slides.
  • Encourage participation and questions by the participants throughout the presentation. Be interactive with your learners.
  • Provide personal stories when possible. People sometimes remember better when personal stories are shared either by you or by the participants.
  • Good visuals will provide guided practice for the learning objectives of the lesson. Activities and demonstration materials can reinforce learning.
  • The adult learner brings a background of learning and experience that contributes to learning. Many will have experienced some of these home hazards in their own homes.
  • The purpose of this information is to empower people with knowledge so they will adopt healthy behaviors and to offer practical, low-cost action steps to solve problems.
  • Emphasize the vulnerability of children for environmental health concerns. These are important concepts to remember:
  • Children are not just little adults. Their organs (especially the brain) and immune systems are still developing, especially until about age 6. Their metabolic rates are faster. Pound-per-pound children drink, eat, and breathe more than adults.
  • Children’s behaviors keep them closer to the floor—where pollutants may collect.

“Both indoor air and outdoor air contains water vapor.
Wherever air goes, water vapor goes. When humid
air contacts a surface that is cold enough, the water
vapor in the air will condense onto that cold surface.” Source:
