straight lines until it reaches the eye.

Unit Three: Structures and Functions of Living Things

Structures and Functions

I can describe how flowers produce seeds.

I can describe how stemscarry water and nutrients from the roots to the leaves.

I can describe how stems provide support to the plant and allow the leaves to reach sunlight.

I can describe how roots provide support by anchoring the plant.

I can describe how roots absorb water and nutrients needed for growth.

I can describe how leaves make food in green plants.

I can recognize that body coverings (fur, feathers, skin, and hair) help control body temperature.

I can recognize that skeletons and exoskeletons provide support.

I can recognize that limbs, wings, fins and muscles help animals move.

I can recognize that animals use jaws, teeth, claws, and beaks for getting food.

I can recognize that animals use exoskeletons, scales, shells, claws, teeth, beaks, legs and wings for protection.

Classifications

I can sort plants based on physical characteristics I can see such as roots, leaves, stems, and flowers.

I can sort seed plants by evergreens or broad-leafed.

I can distinguish between root systems as taproots or branching.

I can organize plants by leaf type, leaf shape, and veins.

I can sort plants by woody stems and green, non-woody stems.

I can sort plants by the type of flower color, shape, and number of petals.

I can arrange animals based on physical characteristics I can see such as backbone, body covering, and limbs.

I can sort animals into two broad categories: animals with backbones (vertebrate - internal skeleton) and animals without backbones (invertebrate - external skeleton/exoskeleton or no skeletal system).

I can classify animals with backbones based on body covering and other characteristics I can see.

I can recognize fish by their scales and gills.

I can recognize amphibians by their smooth, wet skin.

I can recognize reptiles by their rough, dry skin.

I can recognize birds by their wings, two feet, and feathers.

I can recognize mammals because they have hair and feed their young milk.

Environmental Adaptation

I can relate characteristics of plants such as leaf shape, thorns, odor, and/or color that help them survive in their environment.

I can relate characteristics of animals such as sharp teeth, claws, odor, and/or body coverings that help them survive in their environment.

Unit Four: Earth Materials, Change, and Resources

Natural Resources

I can identify natural resources as naturally occurring materials including metals, fuels, fresh water, soil, and forests.

I can explain that natural resources come from living organisms (forests) or from nonliving things (fuels, metals, fresh water).

I can classify natural resources as renewable and non-renewable based on whether the resource can be replaced by nature in a human lifetime (or a reasonable amount of time).

I can define and give an example of renewable resources as resources that can be used again, made again by people or nature, or will never run out (for example, water, forests, plants, animals, sunlight, wind).

I can define and give examples of non-renewable resources as one that cannot be made again by nature or people (for example, oil, gas, minerals). Most come from the ground.

I can tell or write how important it is for people to protect non-renewable resources (because they will run out) and renewable resources (because they can be killed off, overused, or polluted to the point of becoming unusable).

I can define recycling as collecting and returning materials to be manufactured into new products.

I can give examples of some materials that can be recycled: glass, some plastics, paper, aluminum, cardboard, and steel.

I can define reusing as using an item again or finding new uses for them instead of throwing them away.

I can give examples of some materials that can be reused: paper bags, plastic jugs, jars, coffee mugs, plastic containers, etc.

I can define reducing as producing less waste by choosing to buy fewer products or buying less wasteful products to conserve natural resources.

I can give examples of reducing: turning out the lights, using less water, reusing grocery bags, riding bikes, carpooling, using mass transportation, and buying products in bulk or with less packaging.

I can give examples of renewing resources: replanting, reforesting, and composting.

I can recognize that many everyday materials can be recycled.

Human Impact

I can describe how humans depend on their natural environment for clean air, clean water, forests, food, and earth materials such as soil, sand, rocks, and minerals.

I can describe how humans depend on their constructed environments (including homes, neighborhoods, shopping malls, factories, and industry) to meet their basic needs for shelter, work, and recreation.

I can explain that changes that people make to their environment can have helpful or harmful effects.

I can describe some examples of harmful effects that people have on the environment as garbage, habitat destruction, poor use of resources, and pollution.

I can describe some examples of helpful effects that people have on the environment as land management and the management of non-renewable and renewable resources (reduce, reuse, recycle, renew).

Earth Materials

I can recognize that minerals, rock, clay, boulders, gravel, sand, and soil are different types of earth materials.

I can explain that most rocks are made of two or more minerals.

I can explain that the solid material of the earth's crust is rock.

I can explain that when natural processes (like weathering and breakage) break down the earth's crust (rock), it forms earth materials including boulders, gravel, sand, silt, and clay.

I can describe clay as a naturally occurring material composed of fine-grained minerals which becomes hardened when dried or fired.

I can describe soil as a combination of dead, decomposed plants and animals; minerals; different sized rock materials (sand, silt, clay); and nutrients.

I can explain that soils have different properties such as color, texture, and particle size based on their composition.

I can explain that minerals are natural solid substances with a crystalline structure that are found in the earth's crust.

I can explain that rocks are made of two or more minerals that add color, hardness, and sparkle.

Surface Changes

I can identify natural causes of change in the earth's surface. Some happen rapidly and dramatically, and some take millions of years.

I can describe weathering as breaking or wearing away rocks and erosion as the movement of weathered material by wind, water, or ice.

I can describe erosion as a slow, gradual process (like the formation of the Grand Canyon), or it can be as rapid as rainwater running down a steep slope.

I can describe the erosion due to glaciers as a slow process which can move trees, soil, and rock and leave behind soil and rock (like in the state of Michigan).

I can describe volcanoes as an opening in the earth's surface through which lava, volcanic ash, and other materials erupt. This process usually happens quickly.

I can describe landslides as the movement of a large amount of rock, soil, and other materials down a slope. Landslides are an example of a rapid process which can begin with an earthquake, volcano, rainfall, or a man-made activity.

I can describe earthquakes as a very rapid, destructive natural event which causes the earth to tremble and shake, sometimes violently.

Using Earth Materials

I can recognize that bricks are made from a variety of earth materials including clay and rock.

I can recognize that earth materials such as rock and sand are used in building construction.

I can recognize that sand and rock are used in concrete and asphalt for road construction.

I can recognize that sand is used to make glass and glass products.

I can recognize that materials taken from the earth can be used as fuels.

I can describe fuels taken from the earth include oil, natural gas, and coal.

I can explain that different fuels are used for transportation (cars, trains, airplanes), heating and cooling buildings, and construction.
