Course Description

In unit one, students engage in an engineering challenge to develop habits of mind and classroom practices that will be reinforced throughout the school year. In unit two, students build on the science concepts of growth and development of plants and animals from grades K–1 by observing new organisms over time. Students see the life cycles of insects unfold in real time and compare the stages exhibited by each species to reveal patterns. At the same time, students grow one type of plant from seed and observe it through its life cycle to produce new seeds. They gain experience with the ways that plants and insects interact in feeding relationships, seed dispersal, and pollination, and students develop models to communicate their understanding. In unit three, students build on the science concepts of matter and its interactions developed in kindergarten using new tools to enrich observations. Students observe, describe, and compare properties of solids and liquids. They conduct investigations to nd out what happens when solids and water are mixed and when liquids and water are mixed. They use their knowledge of solids and liquids to conduct an investigation on an unknown material (toothpaste). They gain firsthand experience with reversible changes caused by heating or cooling, and read about changes caused by heating that are irreversible. In unit four, students use simple tools to observe, describe, analyze, and sort solid earth materials and learn how the properties of the materials are suited to different purposes. The investigations complement the students’ experiences in the Solids and Liquids Module with a focus on earth materials and the influence of engineering and science on society and the natural world. Students explore how wind and water change the shape of the land and compare ways to slow the process of erosion. Students learn about the important role that earth materials have as natural resources. Throughout all units, students engage in science and engineering practices to collect and interpret data to answer science questions, develop models to communicate interactions and processes, and define problems in order to compare solutions. Students gain experiences that will contribute to understanding of crosscutting concepts of cause and effect; scale, proportion, and quantity; energy and matter; and stability and change.

Unit Summary The Pebbles, Sand, and Silt unit provides experiences that heighten primary students’ awareness, curiosity, and understanding of Earth’s natural resources—

rocks, soil, and water—and provides opportunities for students to engage in scientific and engineering practices. Students explore the natural world by using

simple tools to observe and describe properties of earth materials. In this module, students will

• Observe and compare physical properties of rocks and soils, using various tools. • Rub rocks together and observe that they break into smaller pieces. • Use screens to separate and group river rocks by particle size, and investigate properties of pebbles, gravel, sand, silt, and clay particles. • Explore places where earth materials are naturally found and ways that earth materials are used. • Use sand to make sculptures and clay to make beads, jewelry, and bricks. • Find, collect, record, and compare samples of soil outside the classroom.

What It Looks Like in the Classroom

In this unit of study, students learn that a situation that people want to change or create can be approached as a problem to be solved through engineering.

Before beginning to design a solution, it is important to clearly understand the problem, and asking questions, making observations and gathering information

are helpful in thinking about and clarifying problems. Students learn that designs can be conveyed through sketches, drawings, or physical models, and that

these representations are useful in communicating ideas for a problem’s solutions to other people. As outlined in the narrative above, students will develop

simple sketches or drawings showing how humans have helped minimized the effects of a chosen Earth event.

Students use evidence from several sources to develop an understanding that Earth events can occur quickly or slowly. Because some events happen too quickly

too observe, and others too slowly, we often rely on models and simulations to help us understand how changes to the surface of the Earth are caused by a

number of different Earth events. For example,

● Volcanic eruptions are Earth events that happen very quickly. As volcanic eruptions occur, ash and lava are quickly emitted from the volcano. The flow of

lava from the volcano causes immediate changes to the landscape as it flows and cools.

● Flooding can happen quickly during events such as hurricanes and tsunamis. Flooding can cause rapid changes to the surface of the Earth.

● Rainfall is an event that recurs often over long periods of time and will gradually lead to the weathering and erosion of rocks and soil.

In order to gather information to use as evidence, students need to make observations. They can easily look for evidence of changes caused by rain, flooding, or

drought. However, actually observing Earth events as they happen is often not possible; therefore, students will need opportunities to observe different types of

Earth events using models, simulations, video, and other media and online sources. At this grade level, quantitative measurements of timescales are not

important. Students do need to see the kinds of changes that Earth events cause, and whether the changes are rapid or slow.

Engaging in engineering design helps students understand that a situation that people want to change or create can be approached as a problem to be solved

through engineering. Asking questions, making observations, and gathering information are helpful in clearly understanding the problem. Designs can be

conveyed through sketches, drawings, or physical models. These representations are useful in communicating ideas for a problem’s solutions to other people. In

this unit of study, students need the opportunity to engage in the engineering design process in order to generate and compare multiple solutions designed to

slow or prevent wind or water from changing the shape of the land. Students are not expected to come up with original solutions, although original solutions are

always welcome. The emphasis is on asking questions, making observations, and gathering information in order to compare multiple solutions designed to slow

or prevent wind or water from changing the land. This process should include the following steps:

● As a class, with teacher guidance, students brainstorm a list of natural Earth events, such as a volcanoes, earthquakes, tsunamis, or floods. The class

selects one Earth event to research in order to gather more information.

● As a class or in small groups, with guidance, students conduct research on the selected Earth event using books and other reliable sources. They gather

information about the problems that are caused by the selected event, and gather information on the ways in which humans have minimized the effects

of the chosen earth event. For example,

○ Different designs of dikes or dams to hold back water,

○ Different designs of windbreaks to hold back wind, or

○ Different designs for using plants (shrubs, grass, and/or trees) to hold back the land.

● Next, students look for examples in their community of ways that humans have minimized the effect of natural Earth events. This can be accomplished

through a nature walk or short hike around the schoolyard, during a field trip, or students can make observations around their own neighborhoods. If

available, students can carry digital cameras (or other technology that allows them to take pictures) in order to document any examples they find.

● Groups select one solution they have found through research and develop a simple sketch, drawing, or physical model to illustrate how it minimizes the

effects of the selected Earth event.

● Groups should prepare a presentation using their sketches, drawings, or models, and present them to the class.

Modifications

(Note: Teachers identify the modifications that they will use in the unit. See NGSS Appendix D: All Standards, All Students/Case Studies for vignettes and

14 | Page

explanations of the modifications.)

● Structure lessons around questions that are authentic, relate to students’ interests, social/family background and knowledge of their community.

● Provide students with multiple choices for how they can represent their understandings (e.g. multisensory techniques-auditory/visual aids; pictures,

illustrations, graphs, charts, data tables, multimedia, modeling).

● Provide opportunities for students to connect with people of similar backgrounds (e.g. conversations via digital tool such as SKYPE, experts from the

community helping with a project, journal articles, and biographies).

● Provide multiple grouping opportunities for students to share their ideas and to encourage work among various backgrounds and cultures (e.g. multiple

representation and multimodal experiences).

● Engage students with a variety of Science and Engineering practices to provide students with multiple entry points and multiple ways to demonstrate

their understandings.

● Use project-based science learning to connect science with observable phenomena.

● Structure the learning around explaining or solving a social or community-based issue.

● Provide ELL students with multiple literacy strategies.

● Collaborate with after-school programs or clubs to extend learning opportunities.

● Restructure lesson using UDL principles (http://www.cast.org/our-work/about-udl.html#.VXmoXcfD_UA).

Research on Student Learning

Students of all ages may hold the view that the world was always as it is now, or that any changes that have occurred must have been sudden and

comprehensive. The students in these studies did not, however, have any formal instruction on the topics investigated (NSDL, 2015)

Prior Learning

Kindergarten

● A situation that people want to change or create can be approached as a problem to be solved through engineering. Such problems may have many

acceptable solutions. (secondary)

● Asking questions, making observations, and gathering information are helpful in thinking about problems.

● Before beginning to design a solution, it is important to clearly understand the problem.

● Designs can be conveyed through sketches, drawings, or physical models. These representations are useful in communicating ideas for a problem’s

solutions to other people.

● Because there is always more than one possible solution to a problem, it is useful to compare and test designs.

Future Learning

Grade 3

● When the environment changes in ways that affect a place’s physical characteristics, temperature, or availability of resources, some organisms survive

and reproduce, others move to new locations, yet others move into the transformed environment, and some die.(secondary)

Grade 4

● Rainfall helps to shape the land and affects the types of living things found in a region. Water, ice, wind, living organisms, and gravity break rocks, soils,

and sediments into smaller particles and move them around.

● Testing a solution involves investigating how well it performs under a range of likely conditions. (secondary)

● Possible solutions to a problem are limited by available materials and resources (constraints). The success of a designed solution is determined by

considering the desired features of a solution (criteria). Different proposals for solutions can be compared on the basis of how well each one meets the

16 | Page

specified criteria for success or how well each takes the constraints into account. (secondary)

● Different solutions need to be tested in order to determine which of them best solves the problem, given the criteria and the constraints.(secondary)

● The locations of mountain ranges, deep ocean trenches, ocean floor structures, earthquakes, and volcanoes occur in patterns. Most earthquakes and

volcanoes occur in bands that are often along the boundaries between continents and oceans. Major mountain chains form inside continents or near

their edges. Maps can help locate the different land and water features areas of Earth.

Grade 5

● Nearly all of Earth’s available water is in the ocean. Most fresh water is in glaciers or underground; only a tiny fraction is in streams, lakes, wetlands, and

the atmosphere.

● Earth’s major systems are the geosphere (solid and molten rock, soil, and sediments), the hydrosphere (water and ice), the atmosphere (air), and the

biosphere (living things, including humans). These systems interact in multiple ways to affect Earth’s surface materials and processes. The ocean

supports a variety of ecosystems and organisms, shapes landforms, and influences climate. Winds and clouds in the atmosphere interact with the

landforms to determine patterns of weather.

Interdisciplinary Connections

English Language Arts

Students participate in shared research to gather information about Earth events from texts and other media and digital resources. They will use this

information to answer questions and describe key ideas and details about ways in which the land can change and what causes these changes. Students should

also have opportunities to compose a writing piece, either independently or collaboratively with peers, using digital tools to produce and publish their writing.

Students should describe connections between Earth events and the changes they cause, and they should include photographs, videos, poems, dioramas,

models, drawings, or other visual displays of their work, when appropriate, to clarify ideas, thoughts, and feelings.

Mathematics

17 | Page

Students have multiple opportunities to reason abstractly and quantitatively as they gather information from media sources. Students can organize data into

picture graphs or bar graphs in order to make comparisons. For example, students can graph rainfall amounts. Students can use the data to solve simple

addition and subtraction problems using information from the graphs to determine the amount of change that has occurred to local landforms. For example, a

gulley was 17 inches deep before a rainstorm and 32 inches deep after a rainstorm. How much deeper is it after the rainstorm? Students must also have an

understanding of place value as they encounter the varying timescales on which Earth events can occur. For example, students understand that a period of

thousands of years is much longer than a period of hundreds of years, which in turn is much longer than a period of tens of years. In addition, teachers should

give students opportunities to work with large numbers as they describe length, height, size, and distance when learning about Earth events and the changes

they cause. For example, students might write about a canyon that is 550 feet deep, a river that is 687 miles long, or a forest that began growing about 200

years ago.
