Science Curriculum: Elementary School

Science Elementary

In Montgomery County Public Schools, the goal of the science program is for all students to achieve full scientific literacy through Next Generation Science Standards aligned and phenomenon-based instruction that will prepare them for success in college and career. The MCPS science curriculum was developed as a coherent learning progression from kindergarten through grade 12 where all students experience a rigorous, interdisciplinary approach to science content, exploring science through hands-on explorations, productive discourse, and purposeful reading and writing. Students apply content knowledge through the scientific and engineering practices to solve real world problems and develop the tools that will make them successful lifelong learners.

Grade K Science Course Overview

The Grade K Science curriculum is an NGSS aligned science program that provides opportunities for students to experience an interdisciplinary approach to science content, exploring all three domains of science (Earth/Space, Physical, and Life Sciences) by actively engaging in science using multiple methods and approaches to teaching and learning. Each unit is built around a culminating STEM activity that challenges the students to use their new found knowledge to design and/or build a hands-on project related to unit topics.

influence the ability of plants and animals to meet their needs in their environment?

Unit Anchoring Phenomena

Kindergarten students begin marking period 1 by exploring the practices of scientists and engineers, and make weather observations using their senses.  Students explore the phenomenon of walking barefoot across ground surfaces warmed by sunlight, and go outside to observe the effects of sunlight and shade on objects in the schoolyard and collect data to compare the effects of sunlight on samples of different surface materials. They then use the data to make a claim and test their claims through an investigation of outdoor surfaces. Students deepen their understanding by planning and conducting their own investigation to test the effects of sunlight on papers of different colors.  They will then extend their understanding of sunlight and shade to act as weather scientists forecasting heat waves. This understanding of the effects of sunlight is used to design and build a mini-shade shelter which will then be tested using the engineering design cycle.

In marking period two, students expand their exploration of weather.  They learn to make weather observations and make daily observations for at least two weeks.  They explore rain and wind and will look for patterns in their weather observations.  Students investigate severe wet weather patterns (thunderstorms and blizzards), and act as scientists to develop a forecast.  Finally, students apply their understanding of weather patterns and severe wet weather to investigate materials, and design and test a roof to keep the rain/snow out of a schoolyard shed.
