Why HMH Science Dimensions?
HMH Field Trips powered by Google Expeditions

As a Google^® content partner, HMH has developed field trips for Google Expeditions. Using a simple Google Cardboard™ device and a smartphone, students are swept away into 3D, 360-degree experiences in fascinating locations, directly tied to science content! A Teacher Guide provides ideas for incorporating the Expeditions into your lessons, as well as tips on how to guide and customize the experience.

Designed to Raise Science Achievement in ALL Students

Houghton Mifflin Harcourt is proud to partner with you to raise the level of scientific achievement for all students and to better spark students’ curiosity in science to prepare them for college, career, and global citizenship.

HMH Science Dimensions’ curriculum materials align with the National Research Council’s Three Dimensions of Learning: Disciplinary Core Ideas, Crosscutting Concepts, and Science and Engineering Practices. These intertwined curriculum strands are expertly woven together into each lesson in order to meet the Performance Expectations (PEs). Research has shown that this braided, bundled approach best prepares students to succeed.

Professional Learning to Help You Through the Transition

In addition to independent professional development courses that support both program implementation and best practices for transitioning to an NGSS* curriculum, professional learning is also built directly into the core curriculum with just-in-time videos featuring our dynamic consulting authors guiding teachers through the key approaches that ensure NGSS success.

Activity-led Learning

Learning Activities are no longer an accessory to learning—they form the foundation of every lesson! The program provides abundant opportunities for students to collaborate, work in teams to devise solutions, perform hands-on experiments, build models, and journal in science notebooks. Lessons always begin with a problem to solve or a discrepant event or phenomenon to explain, which lays the groundwork for students to explore science in the same way real-life scientists do, by starting with a question.

Engineering and STEM as an Essential Part of the Curriculum

In HMH Science Dimensions, engineering and STEM are considered an integral part of the curriculum. Engineering and engineering design features are incorporated throughout all the features and activities. Watch your students’ eyes light up as they brainstorm solutions, share their ideas, and experiment to find solutions. They'll become experts in the engineering design process by practicing their skills in unit performance tasks called Engineer It!.

Superior Digital Learning Experience

Finally, a digital program that exceeds the learning experience of anything available in print. Go fully digital, or seamlessly blend digital with print—HMH Science Dimensions has the flexibility to match your classroom’s digital capacity.

Performance-Based Assessment

HMH Science Dimensions prepares students to succeed on high-stakes performance-based assessments by weaving three-dimensional learning and hands-on applications into every day of teaching. The interactive online Student Edition provides students with valuable experience answering technology-enhanced item types, which increases their comfort level with computer-based testing.

Every step of the learning process includes a scaffolded assessment strategy. This leads to summative performance assessments that help teachers predict how well students will perform on high-stakes assessments based on the NGSS Performance Expectations.

  The labeling in the Teacher Edition clearly identifies all of the Performance Expectations, Science and Engineering Practices, Disciplinary Core Ideas, and Crosscutting Concepts, including the math and ELA connections. This helps educators identify the standards that are being covered in any given lesson.
  
  A Spiraled and Comprehensive Standards Solution
  
  The HMH Science Dimensions Trace Tool to the NGSS helps you make sense of NGSS, understand how the standards connect and spiral from one grade to another, and identify HMH resources to support your instruction.
  
  You can trace the standards by PEs, SEPs, CCCs, or DCIs. When you click on a standard, you can view where in the program that standard is covered. But, the Trace Tool is even more powerful than a traditional correlation because it shows you how that standard spirals through every grade, from K to 12.
  
  Engaging Disciplinary Core Ideas Coverage
  
  For Grades K–8, HMH Science Dimensions includes access to ScienceSaurus^® for additional DCI coverage. This convenient handbook covers life, Earth and space, physical, and environmental science, as well as engineering and technology. Clear explanations with dynamic visuals can be used for presentation, review, or reinforcement of science concepts.
  
  In high school, HMH Science Dimensions incorporates the valued work of Randall Munroe, of xkcd.com fame, and his book Thing Explainer. Munroe’s highly engaging illustrations and accessible explanations for key science topics help students gain a better understanding of both scientific ideas and processes. Plus, HMH Science Dimensions Biology and Chemistry will include all-new illustrations never before seen in Thing Explainer or xkcd.com!
  
  Create Strong Cross-Curricular Connections
  
  Science literacy is incomplete without a strong foundation in math and ELA. HMH Science Dimensions offers Common Core Math and ELA connections throughout the curriculum. Strong math and reading skills are essential to quality STEM learning.

- Student-Led Activities and Investigations
  
  Every Lesson Is an Activity
  
  At its core, learning science is about doing science. HMH Science Dimensions™ provides rich opportunities for students to conduct hands-on investigations, solve problems, and discuss their findings with teachers and classmates. In HMH Science Dimensions, “activity” means more than just “lab.” It means opportunities for collaboration, gathering evidence, presenting arguments, and journaling in science notebooks.
  
  Start with a Question to Spark Curiosity
  
  Each lesson begins with “Can You Explain It?,” a problem to solve or discrepant event to explain, in order to engage students with an activity that is interesting, captivating, fun, and challenging. This lesson-leading feature provides intrinsic motivation to spark curiosity and serves as the context for the three-dimensional learning and hands-on activities throughout the lessons. Students are motivated to think critically and construct explanations of how and why.
  
  The program is built around active learning. Rather than receive content passively, students are asked to solve problems or explain phenomena by stating claims, gathering evidence, and providing explanations through reasoning.
  
  Support Reasoning and Strengthen Writing Skills
  
  HMH Science Dimensions follows the Claims-Evidence-Reasoning model of scientific explanations. Many of the lessons in HMH Science Dimensions support the use of Evidence Notebooks. Helpful prompts have been inserted throughout the lessons to help students know when to use these notebooks. Students will love creating their own study guide that can be taken into the next grade, and teachers will love the extra writing practice!
  
  Drive Student Inquiry with Hands-On Investigations
  
  Hands-on Activities are integrated into many of the lessons. These are built with teachers’ busy schedules in mind. Each activity uses easily sourced materials and clear instructions are stepped out for the student.
  
  Students get to actively “do science” while thinking critically about their observations, gathering evidence, and defending their claims.
  
  Encourage Collaboration
  
  Working in a team is an essential part of developing 21st-century skills. HMH Science Dimensions provides ample opportunities for students to participate in groups to complete activities and partner with their peers to discuss their findings.
