Explain to students that they just went through the littleBits Invention Cycle. They created a first prototype, Played with it to see how it worked, then Remixed it with adjustments, improvements, and perhaps tried a few totally different approaches. After a lot of experimentation and comparison, they got to Share their results with others, collecting feedback and inspiration. Lots of designers and engineers have a process they go through when inventing. This is the process the team at littleBits uses when they create new Bits and Kits. The students will also be using it when they complete their littleBits challenges.
If God communicates His intention through His servants the prophets, and Satan counterfeits the messages of God through false prophets, then it is vital that we test the prophets to see if the message is indeed from God. On one hand, the Scriptures admonish us to "Despise not prophesyings" (1 Thessalonians 5:2) and to "Believe in the LORD your God, so shall ye be established; believe his prophets, so shall ye prosper" (2 Chronicles 20:20).
