They observe, quantify, compare, and record length in centimeters, mass in grams, volume in milliliters, and temperature in degrees Celsius. They use metric measurement to solve problems. Physics of Sound Students investigate sound as a product of a vibrating object. They explore the variables that determine sound pitch and amplification and compare how sound travels through air, water, and solids.
Students observe how electricity in circuits can produce sound.
They investigate the concepts and principles of how simple machines can be used to move an object. They discover the relationships between distance, force, speed and direction when using various levers and gear arrangements. Finally, they use the concepts and principles they learned to solve every day problems. Students compare properties of seeds and fruits, germinate seeds, and grow hydroponically to observe plant life cycle. They maintain crayfish and land snails, and observe and compare their structures and behaviors.
