Get your Pre-K/Kinder kids ready for science through a fun, safe, easy experiment and lesson plan. This lesson packet includes detailed lesson plans, handouts, and templates for prediction signs so students can investigate acids and bases, and more importantly understand how scientists think scientifically! The packet includes story-book-like pictures that walk students through the lesson, with teacher scripts on the back. Students learn about bubbles, and that bubbling occurs when acids and bases mix. Students then explore a carefully scaffolded experiment that can be done by students themselves, or as demonstrations with household materials. Students try to find patterns in each experiment and make predictions using their prediction signs. There are great teachable moments about key aspects of science throughout this lesson, all of which are noted in the lesson plan and on the teaching scripts. Students then apply their understanding of acids and bases to a real-world example. This lesson is designed to work with both native and ESL students, and encourages vocabulary building, inquiry skills and prediction. A great introduction to science!
