Generate sounds using different materials, objects and techniques. Record the sounds and then discuss and share the results.


Investigate how the loudness and pitch of sound changes when the rate of vibrations changes.


Investigate and recognize that sound moves through solids, liquids and gases (e.g., air).


Investigate how light travels through the air and tends to maintain its direction until it interacts with some other object or material.


Observe and describe how light is absorbed, changes its direction, is reflected back and passes through objects. Observe and describe that a shadow results when light cannot pass through an object.


Describe evidence to support the idea that light and sound are forms of energy.


Examine the physical properties of rock samples and sort them into categories based on size using simple tools such as sieves.


Observe the detailed characteristics of rocks and minerals. Identify rocks as being composed of different combinations of minerals.


Classify and identify minerals by their physical properties of hardness, color, luster and streak.


Identify fossils and describe how they provide evidence about the plants and animals that lived long ago and the nature of their environment at that time.


Describe natural materials and give examples of how they sustain the lives of plants and animals.


Describe how the properties of earth materials make them useful to humans in different ways. Describe ways that humans have altered these resources to meet their needs for survival.


Identify the common structures of a plant including its roots, stems, leaves, flowers, fruits and seeds. Describe their functions.


Investigate plant growth over time, take measurements in SI units, record the data and display the data in graphs. Examine factors that might influence plant growth.


Choose and use the appropriate tools to estimate and measure length, mass and temperature in SI units.


Define the uses and types of simple machines and utilize simple machines in the solution to a ?real world? problem.
