Transforming science education through research-driven innovation



OpenSciEd Middle Grades Science Units


The OpenSciEd initiative was launched to address a critical need in science education: the need for high quality science instructional materials that are standards-aligned and practical for broad implementation. Led by BSCS Science Learning, a national consortium of curriculum developers and researchers created a three-year middle school science program for free distribution.

The program’s classroom materials and associated teacher professional learning materials are

  • designed to align with the NRC Framework for K-12 Science Education and the Next Generation Science Standards (NGSS),
  • based on research on student learning and teacher practice,
  • developed in collaboration with teachers and field-tested in hundreds of classrooms in ten states across the United States,
  • open-source and locally adaptable, and
  • continuously improved based on feedback from teachers and field testing.

The complete, three-year middle grades science program is now available for free download at openscied.org.

Weather, Climate & Water Cycling 

Weather, Climate & Water Cycling

This 6th grade unit on weather, climate, and water cycling is broken into four separate lesson sets. In the first two lesson sets, students explain small-scale storms. In the third and fourth lesson sets, students explain mesoscale weather systems and climate-level patterns of precipitation. Each of these two parts of the unit is grounded in a different anchoring phenomenon.

The unit starts out with anchoring students in the exploration of a series of videos of hailstorms from different locations across the country at different times of the year. The videos show that pieces of ice of different sizes (some very large) are falling out of the sky, sometimes accompanied by rain and wind gusts, all on days when the temperature of the air outside remained above freezing for the entire day. These cases spark questions and ideas for investigations, such as investigating how ice can be falling from the sky on a warm day, how clouds form, why some clouds produce storms with large amounts of precipitation and others don’t, and how all that water gets into the air in the first place.

The second half of the unit is anchored in the exploration of a weather report of a winter storm that affected large portions of the midwestern United States. The maps, transcripts, and video that students analyze show them that the storm was forecasted to produce large amounts of snow and ice accumulation in large portions of the northeastern part of the country within the next day. This case sparks questions and ideas for investigations around trying to figure out what could be causing such a large-scale storm and why it would end up affecting a different part of the country a day later.


Matter Cycling & Photosynthesis

This 7th grade unit on matter cycling and photosynthesis begins with students reflecting on what they ate for breakfast. Questions about where their food comes from lead them to consider which breakfast items might be from plants. Then students explore (and taste) a common breakfast food, maple syrup, and see that according to the label, it is 100% from a tree.

Students apply what they learned in a previous unit to argue that they know what happens to sugar in syrup or other foods when they consume it. Students explore what else is in food and discover that foods from plants not only have sugars but proteins and fats as well. This discovery leads them to wonder how plants are getting these food molecules, why a plant needs food, and where a plant’s food comes from in the first place. Students figure out that they can trace all food back to plants, including processed and synthetic food. They explain that the pieces of their food are constantly recycled between living and nonliving parts of a system.


Forces at a Distance 

Compass

This 8th grade unit launches with a slow motion video of a speaker vibrating. Students explore the cause of a speaker’s vibration as opposed to the effect.

Students dissect speakers to explore what’s inside, and they build homemade cup speakers. They identify that speakers of all kinds have some of the same parts—a magnet, a coil of wire, and a membrane. Students investigate each of these parts to figure out how they work together in the speaker system. Along the way, students manipulate the parts to see how this technology could be modified to apply to systems in very different contexts, like MagLev trains, junkyard magnets, and electric motors.


Thermal Energy

This unit on thermal energy engages students in a design challenge to create a cup that keeps drinks cold longer. They identify the features that make some cups better at keeping drinks cold, and they construct their own models to explain how those features prevent the transfer of thermal energy.

In this unit for 6th grade, students build an understanding of energy transfer within and between materials based on a particle model, and they work on the practices of modeling, conducting investigations, constructing explanations, arguing from evidence, and designing solutions.


Metabolic Reactions

This unit on metabolic reactions in the human body engages students in an investigation of a real case study of M’Kenna, a 13-year-old girl, who reported some alarming medical symptoms to her doctor. Her case sparks questions and ideas for investigations to figure out which parts of M’Kenna’s body are functioning differently from a healthy person’s system and why. Through the work of investigating M’Kenna’s symptoms, the class constructs a model to explain what happens to food after it enters people’s bodies, and they use it to explain M’Kenna’s symptoms.

In this 7th grade unit, students build an understanding of how body systems interact to process food and use the energy stored within it. They work on the practices of developing models, interpreting data, and arguing from evidence.


Sound Waves 

Hands hitting a drum

In this unit, students investigate how sounds can cause objects at a distance to move. Motivated by a video of windows shaking when a truck outside plays loud music, students investigate what happens when an object makes sound. Over the course of the unit, they build a model that describes what happens when sounds are created that can explain the shaking windows and other examples of sounds causing objects to move.

In this 8th grade unit, students use a particle model of air to build an understanding of how sounds move that explains the effect of sounds on other objects. They work on the practices of planning and conducting investigations, using mathematical and computational thinking, and evidence-based argumentation.

The consortium of curriculum developers includes BSCS, Boston College, the Dana Center at The University of Texas at Austin, Digital Promise Global, Northwestern University, and a broad network of leaders in science education. This developers consortium works in close collaboration with a state steering committee representing ten partner states from across the United States.

What is the best time of year to host a lilac blossom festival? Does a plastic bag tax work to reduce litter in the environment? Students now have the opportunity to explore large data sets to answer questions like these and ultimately increase their confidence in analyzing data.

What's Included for Teachers

BSCS Science Learning has launched Invitations to Inquiry to help middle and high school students work with community and citizen science data from projects hosted on FieldScope–BSCS’s platform for collecting, displaying, and analyzing data. Invitations to Inquiry are activities in which students explore FieldScope’s mapping and graphing tools to dig into data in the context of meaningful questions.

Each lesson engages students in interpreting graphs and maps to learn about where the data are collected and what they mean. In one Inquiry, students use data from the Chesapeake Bay estuary to determine suitable sites for oyster reef restoration. In another, students investigate light pollution using a data set collected by individuals throughout the globe.

The Invitations are designed for 2-4 days of learning and support the science and engineering practices from the Next Generation Science Standards. They include teacher guides, slides, handouts, and other instructional resources and supports. Although the Invitations are designed for classroom learning with computer access, each activity offers an opportunity for students to collect data and contribute to a community science project.

BSCS’s Invitations to Inquiry for the classroom can be accessed here. Educators and parents supporting learning at-home can access student-directed versions of Invitations to Inquiry here.

For a school district, the adoption of instructional materials is a costly investment with long-term impacts. This decision-making process is critically important because instructional materials can either support or inhibit improvements in teaching and learning.

Historically, the selection process can be as simple as an individual leafing through materials—sometimes referred to as a “thumb test”—or as intensive as a year-long process involving teams of teachers and administrators. BSCS Science Learning and its collaborators have designed the NextGen TIME program for districts that are prepared to make an investment in the process to go beyond mere selection of materials to planning for implementation in order to maximize the benefit of their instructional materials.

NextGen TIME is a suite of tools and processes designed for professional development of leaders at the state, district, and school levels. Over the course of the NextGen TIME program, teams of educators are guided through the evaluation, selection, and planning for implementation of materials that will help teachers enact the vision of the Next Generation Science Standards (NGSS) in their classrooms. All program tools are freely available.

Educators in central O’ahu want to immerse students in traditional and next generation science learning in a way that deepens their connection to the place of Hawaiʻi. With this goal in mind, the Leilehua-Mililani-Waialua Complex partnered with BSCS Science Learning to co-design and field-test a new curriculum unit for middle school students.

The resulting science unit, Restoring Ea, is place-based, three-dimensional, and phenomenon-focused. While specifically designed for seventh grade teachers and students in central O’ahu, Restoring Ea could be adapted and used by middle school teachers across the country who are looking to engage their students in meaningful, next generation science learning.

The Restoring Ea unit includes classroom materials and associated professional learning resources. It is now freely available.

About the Unit

Restoring Ea is a place-based middle school science unit exploring management strategies that could be used for the Loko ea fishpond to sustainably feed people and ensure the ecosystem is healthy and pono (balanced). This unit honors and leverages traditional and scientific ways of knowing to create experiences that connect students to ‘āina (land) through investigations of place. Focused on ecosystems and food sovereignty, students begin with an exploration of food shortages during emergencies and learn that Hawai’i imports most of its food, including fish. Students wonder how their kūpuna (ancestors) fed themselves prior to importing food. They learn that loko i’a (fishponds) used to feed many people, and one fishpond, Loko ea, is being restored to improve the ecosystem and feed people. Local teachers and students visit Loko ea to kilo (observe), hear mo’olelo (stories) about her past and present, and participate in stewardship activities. In the classroom, teachers help their students investigate the relationships between the desired fish and other key organisms that live at Loko ea. Students consider the ideal environmental conditions for the desired fish and how changes to the environmental conditions affect Loko ea and her organisms.

This unit leverages BSCS’s FieldScope  interactive community & citizen science platform to allow students to investigate environmental data previously collected at Loko ea over time and also to collect additional data themselves.
