The STEM challenges and activities encourage your child to think creatively and explore different ideas to solve problems. Parents act as facilitators, guiding their children through the problem-solving process. Each unit includes stories and practice pages that help children understand science concepts and provide a foundation for completing each STEM challenge. A STEM journal activity helps guide children through the engineering design process: plan, create, test, and record. Topics within each STEM challenge target earth, life, and physical science. Each unit covers a specific scientific concept and includes: Science Story: Introduces each science concept Practice Activities: Support children's understanding STEM Story: Fictional story with a problem to solve STEM Challenge: Hands-on activity to solve a problem STEM Journal: Provides a planning outline to help complete the challenge activity Includes answer key. PreK STEM skills include: Visual discrimination Fine motor skills Comparisons Letter formation Sequencing PreK activities incorporate scientific concepts such as: Physical science Shapes and sizes Magnets Floating/sinking Life science Animals Plants People grow and change Earth science Rocks Weather Air Use Smart Start: STEM for enrichment at home and help your child develop lifelong critical thinking skills.
