Two birds, one stone.
Easy home science experiments that can also be Bible lessons.
These experiments can be emailed to families, or recreated in your own video with your own narrated points you want to make. It's helpful to email the videos too, but the idea is for kids to do these "hands on" at home.
Four Science Experiments that Demonstrate Biblical Ideas from ResourceUMC.org, including elephant's toothpaste and the soap-repelling-pepper (sin) demonstrations. I like the flowers in colored water "experiment" because it visually demonstrates how God's goodness and presence can change us. The links to the videos are in the article.
The orange that floats, and the orange that sinks
This a-peeling demonstration was originally about "the armor of God" that protects us (keeps us afloat), but I would suggest making it about "faith" being the peel that keeps us afloat in difficult times (like these). Here's the YouTube video of it. What else keeps us afloat? Prayer, worship, not being self-centered, making good use of our time and circumstances rather than worrying.
How things "fly" and how our faith and "spirits" can be lifted by God's Spirit
The Bernouli Effect is always fun to demonstrate. In this video, a ping pong ball and hair dryer are used. You can also use a leaf blower and try various balls. The science point is worth explaining because it explains how kites, bird wings, and airplanes work. The faith point is that we are to "live" in God's spirit (spirit = wind, breath, moving force). God's Spirit can also "lift our spirits." And we can lift up each other.
