The student will investigate and understand that the position, motion, and physical properties of an object can be described. Key concepts include
a) colors (red, orange, yellow, green, blue, purple), white, and black;
b) shapes (circle, triangle, square, and rectangle) and forms (flexible/stiff, straight/curved);
c) textures (rough/smooth) and feel (hard/soft);
d) relative size and weight (big/little, large/small, heavy/light, wide/thin, long/short); and
e) position (over/under, in/out, above/below, left/right) and speed (fast/slow).
STANDARD K-5 The student will
investigate and understand that water flows and has properties that can be
observed and tested. Key concepts include
a) water occurs in different states (solid, liquid, gas);
b) the natural flow of water is downhill; and
c) some materials float in water, while others sink.
1ST GRADE Standard
The student will investigate and understand
how different common materials interact with water. Key concepts include
a) some liquids will separate when mixed with water, but others will not;
b) some common solids will dissolve in water, but others will not; and
c) some substances will dissolve more readily in hot water than in cold water.
1ST GRADERS SHOULD LEARN:
· Different types of materials react differently when mixed with water.
· Some liquids will mix with water, while others will not.
· Some solids will dissolve in water, while others will not.
· The temperature of the water affects how easily a substance will dissolve in it.
BE ABLE TO:
· describe and apply the term dissolve.
· predict and describe how various materials (vinegar, milk, baking soda, powdered drink mix, sugar, salt, sand, oil, soil, rocks) act when mixed with water.
· classify liquids and solids into those that will dissolve in water and those that will not. Use picture graphs, tables, and/or charts to record and display the information.
· infer that some substances will dissolve more easily in hot water than in cold water by conducting investigations using water at different temperatures.
Standard 2.3 The student will investigate and
understand basic properties of solids, liquids, and gases. Key concepts
a) mass and volume; and
b) processes involved with changes in matter from one state to another (condensation, evaporation, melting, and freezing).
2ND GRADERS SHOULD
· All common substances are made of matter.
· Matter is anything that has mass and takes up space.
· Mass is a measure of the amount of matter.
· Volume is the measure of the amount of space occupied by matter.
· Matter most commonly occurs in three states: solids, liquids, and gases.
· Matter can change from one state to another.
· When matter changes from one state to another, these changes are referred to as physical changes.
· Changes from solid to liquid to gas require heat energy.
AND BE ABLE
· classify materials as to whether they are liquids, solids, or gases.
· measure the mass of solids and the volume of liquids in metric and standard English units.
· design an investigation to determine basic factors that affect the evaporation of water.
· examine and describe the transformation of matter from one state to another, i.e., solid water (ice) to liquid (water) to gas (steam).
· conduct an investigation to observe the condensation of water.
· describe and identify examples of condensation, evaporation, melting, and freezing of water.
· identify the uses of water in the home and at school.
Standard 3.3 The student will investigate and
understand that objects are made of materials that can be described by
their physical properties. Key concepts include
3RD GRADERS SHOULD
· Objects are made of one or more materials.
· All materials are composed of parts too small to be seen without magnification.
· Physical properties remain the same even if the material (e.g., plastic, paper, metal, ice) is reduced in size.
BE ABLE TO:
· infer that objects are made of one or more materials based on observations of the physical properties that are common to each individual object.
· compare the physical properties of smaller pieces of a material to those physical properties of the entire material.
· conclude that materials have their own set of physical properties that are observable.
· explain that physical properties are observable characteristics that enable one to differentiate objects.
· design an investigation to determine if the physical properties of a material will remain the same if the material is reduced in size.
