The 13 robust science units present important science concepts, supporting Next Generation Science Standards (NGSS) in life, earth, and physical science.

Each unit guides students in exploring a science concept following the 5E model: Engage, Explore, Explain, Evaluate, and Extend. The variety of activities helps to build on students' prior knowledge and experience and helps them apply their understanding of the science concept in a creative way.

Science Lessons and Investigations provides you with teaching support and comprehensive science units that include:

• Concept engagement activity that sparks students' interest and engages prior knowledge by introducing each topic with questions and discussion. (Engage)
• Exploration activity that helps students explore the concept through hands-on investigation. (Explore)
• Reading selections, real-life visuals, and vocabulary review to help students develop understanding. (Explain)
• Comprehension activities incorporating higher-order thinking to help students show and apply what they have learned. (Evaluate)
• Writing prompts and hands-on activities* to help students apply and extend their understanding. (Extend)

*The hands-on activities may include science experiments, STEM challenges, art projects, taking on the role of a scientist, or other cross-curricular activities.
