The Science Mill’s monthly Home School Day focuses on careers in engineering: use your engineering skills to take wild ideas from design to reality: A roller coaster for marbles! A maze for robots! Catapults that play catch! Challenge yourself to build crazy contraptions from unusual materials, including a sky-high tower from bamboo skewers. Register in advance for immersive Learning Labs. Plus, students can explore the museum’s 50+ unique exhibits and see “Incredible Predators 3D”.
