Generate excitement for STEM careers

Interacting with science concepts in an authentic, investigative setting helps students learn what the work of scientists feels like and motivates them to envision future roles in STEM careers for themselves. Profiles of people in science and engineering careers at the end of each unit further pique student interest.

Develop problem-solving skills

Making the engineering design process (EDP) an integral part of the curriculum, HMH Science Dimensions asks students to brainstorm solutions, collaborate on ideas, and solve real-world problems. Performance Tasks in each unit offer multiple opportunities to apply the EDP by defining a problem and designing a solution.

Create deeper understanding with 3D learning

With each learning objective based on the Three Dimensions of Learning, students are planning and conducting investigations, using evidence to explain their findings, and demonstrating their comprehension of a concept—resulting in enduring understanding.

Turn students into active, investigative learners

Taking charge of hands-on investigations, making claims, and learning to think critically helps students gain confidence in their scientific reasoning skills. Take It Features at the end of each lesson let students choose topics to explore in further depth.

Advance literacy and math skills in science class

In addition to science standards, connections throughout the program to literacy and math standards ensure that students are developing nonfiction reading and writing skills and learning to apply math in real-world situations.
