Instruction:

• Read StemScopedia Section C.9AB - Gas Laws - Take notes and answer the questions as you read. When you have finished, write a summary of what you learned.

Activities:

• Virtual Lab - Go to the PhET simulation Gases Intro. Complete the lab by following this procedure: Exploring the Behavior of Gases. You will be asked to make a copy of the Google document in your drive. Save the document with Behavior of Gases Lab as the file name. Complete the procedure, recording data and answering the questions on the Google document or notebook paper as you go. When you are finished, submit the completed lab assignment into Canvas or email it to your teacher.

Review:

• Complete the Quizizz assignment found here using the join code provided by your teacher.

Create a poster presentation that describes how thermal energy transfer allows a system, such as the human body, heat pumps, or weather, to function.

• Include the method of thermal energy transfer, convection, conduction, or radiation, at each transfer point in the system and a summary of how energy is conserved.

Research sound and take notes. Define the terms above and complete the following:

Activities

1. Experiment with the speed of sound in different media. Lean against the wall with one ear pressed firmly against the wall and one ear open to the air. Have someone tap on the wall gradually increasing their distance from you until you can not hear the tapping. Record observations: what did you notice with the sound through the wall verses the sound through air.

• Do the same experiment but this time have your lab assistant stomp on the floor on the opposite end of the house. Remember to leave room to increase the distance.The resonance is better at 2:00 in the morning. Again Record observations: compare your observations to the wall experiment. Did you notice a difference? Explain what you think caused this using scientific evidence and reasoning.

• Extension: If you live near a long pipe fence do it again and see if you can time the difference it takes for the sound to travel through the metal versus the air. Use a shoe so that you don’t hurt the pipe. (I would take the shoe off also)

1. Create water waves in your sink by tapping lightly on the surface with uniform tapping. Can you identify any patterns? Record your observations in a journal. What happens when you apply a second set of waves by tapping on the opposite side of the sink? Can you clearly identify any interference patterns? Describe the changes you observe.

The body systems of the Human work together to keep us alive.

• Research the 11 human body systems. Create a table with the system name and main functions of that system. (integumentary, muscular, skeletal, nervous, circulatory, lymphatic, respiratory, endocrine, urinary/excretory, reproductive and digestive). Name systems that interact with each other and give examples.
