Test the spoons
Put a metal spoon, a plastic spoon and a wooden spoon in a cup of warm water and have kids feel the handles after a minute. The metal one warms up fastest! Then they sort materials into conductors and insulators. Feeling it first makes the vocabulary stick.
Why it works: kids understand an idea best when they touch it, then draw it, then write it, the order the U.S. Department of Education recommends for elementary math.
