A wise old king tells his subjects how he has decided to have a "uniform system" of measurement (SI Units) so everybody is on the same page! What a clever king! And so will your kids be after learning from this brilliant story about SI Units brought to you by ScienceWithMe! Highly recommended! Homeschoolers, parents, teachers and kids love it!!!
