🌙🔬 Today in Lab Littles, our little scientists explored the phases of the moon!

We started by learning about the different phases of the moon and then created our very own edible moon phase models using cookies. The fun continued with moon-themed games, movement activities, and a glowing sensory experience that transformed our classroom into a magical nighttime sky! ✨

From full moons to crescent moons, our curious learners discovered that science can be hands-on, delicious, and full of wonder. 🌕🌖🌗🌘🌑

Mini Movers Mondays = tiny hands, busy feet, rainbow crafts, and the sweetest little giggles 🌈✨

This morning our little movers explored sensory play, practiced fine motor skills, made beautiful rainbow clouds, danced, played instruments, and chased bubbles across the room like tiny tornadoes of joy 🫧💛 From pom poms and music to crafts and movement, every moment was packed with smiles and discovery!

We love starting our week with Mini Movers and watching friendships, confidence, and imagination grow one colorful activity at a time 💫
