Students will investigate sound and make observation that when sound waves are collected and directed toward the ear it increases the ability to hear. They will also explore how sound waves travel differently through solids, liquids, and gases.
Students will relate the pitch of sound to the length of a vibrating object. Investigations will be conducted with both air and water.
Students will investigate constant and changing (accelerated) motion. They will calculate speed from distance and time measurements and observe the differences between the distance vs. time graph for each motion.
Students will examine the thermal energy transfer through a pane glass window and to clarify the physical definitions of heat and thermal transfer.
Students will learn what organs aid in digestion and how digestion occurs in the human body.
Students will demonstrate that work equals force times distance and investigate the connection between work and potential energy, kinetic energy, and heat.
Students will be able to describe the four functions of the skin.
Students will understand the relationship between heat, specific foods, and calories. Students will learn how to calculate the temperature and mass of the foods and determine how much heat is given off under specific conditions. Students will also learn how to use laboratory equipment to develop this specific experiment.
Students will write the electron configuration for various elements, given the atomic number. Given the location of an element on the periodic table, students will be able to give the highest energy level the valence electrons are on, and how many valence electrons it has.
In this lesson, work and power will be demonstrated and explained. Students will also observe that entropy is a real process that must occur whenever work occurs.
Students will test pH of various substances and mix substances to investigate neutralization.
