Working with kids and parents together
Make sure kids are doing the work or activity, don’t let the parents take over
Engage parents as well as kids, talk to both
Make sure parents are included
If something is going to be loud or provide a flash of light, depending on the age of the kids, warn the parents that the next demo will be loud or flashy, so they know whether to shield their kids from the sound or view (this is important when doing demo shows for mixed audiences of kids of many ages and parents. For example: smashing things that have been frozen with LN2. Older kids like the view and sound of it, but a younger kid that might be in the audience, say age 5 or so, might become frightened by the noise.
