Introduction to Waves

Go to Pearson's textbook login: 
https://www.pearsonsuccessnet.com/snpapp/login/login.jsp

Once you are logged in, go to the "Sound and Light" textbook.  We will be working with this text for the remainder of the semester, focusing on waves and sound.  Use Chapter 1 (Characteristics of Waves), Sections 1 and 2 to help you with the following task.  Be sure to use the videos, as well...they are really helpful.  You may work in a group of 2, no more:

Create a Keynote presentation, using Doodle Buddy to create pictures (all pictures used must be made by your group).  Include the following:

1.  Explain how waves transfer energy and what causes waves.  Include LABELED pictures with your description.

2. Describe transverse and longitudinal waves.  Include LABELED pictures with your descriptions using the slinky provided.

3. Describe amplitude, wavelength, and frequency in relation to transverse and longitudinal waves.  Include LABELED pictures with your descriptions.

4.  Project Piece

Some waves involve repeating patterns, or cycles. Any motion that repeats itself at regular intervals is called periodic motion. The hands moving on a clock, a child swinging on a swing, and a Ferris wheel going round and round are examples of periodic motion.

Your GoalTo find original examples of periodic motion and describe them
To complete this project you must

• identify examples of periodic motion or events that have periodic characteristics
• collect and organize data on the frequency and duration of each event
• present your findings

Project Directions Plan It With your group, brainstorm examples of objects or events that go back and forth or alternate from high to low, dark to light, loud to quiet, or crowded to uncrowded. Select at least two objects or events to observe. Your observations can be from video found online or something around campus.  Record data such as how long it takes for the event to finish and start again or the highest and lowest point of the object’s motion. Finally, organize your findings to present in your Keynote.

-Quickly poke the mixture
-Lay your finger on the mixture surface
-Hold the mixture in your palm
-Squeeze the mixture tightly
-Set a spoon on the surface
-Stir the mixture
-Push the mixture
-Remove your hand from the mixture

pHet Lab

Record your lab in "Pages" on your iPad.

Go to the "Density" pHet lab by clicking on this link: http://phet.colorado.edu/en/simulation/density

1. Keep the right hand "Blocks" box on "Custom"
2. Keep the left hand box clicked on "Material".  Do not adjust the sliders for now.
3. Create a data table (in Pages) to record the objects' (styrofoam, wood, ice, brick, aluminum) mass, volume, density and observations (does it float or sink).
4. Which block is closest to the density of water?  How do you know this?  (answer in Pages)
5. Next, change the left corner box from "Material" to "My Block".  Create a block that is closest to the density of water.  Record it's mass, volume, density and observations in your data table.
6. Click on "Same Mass" in the right hand box.  Notice that you have four blocks of different sizes, but the same mass.  Create a new data table having a space for each block, whether your predict it will float or sink, and whether it does float or sink.  Next, drop each block into the water.
7.  Each block has the same mass.  Why did some float and some sink?  Why did they sink at different rates?  (Observe again, if necessary)  Answer in Pages.
8.  Click on "Same Volume" in the right hand box.  Create a data table for each block and your prediction of whether it will float or sink and your observation of what happens.  Drop each block into the water.
9.  Describe your results.  Each block is the same size, why did blocks sink and float?  Why did some float higher?
10. Create a new data table recording each block, your prediction of what will happen after being dropped in the water, and what does happen after being dropped in the water for blocks with the "Same Density".

Lab Safety and iMovie Project

We will be completing a lot of labs throughout the year.  To fully participate, you need to follow the safety guidelines.  You will be removed from the lab and given an alternate assignment if you fail to follow these simple lab rules.

1. Horseplay will not be tolerated.  Be careful and on your best behavior while in the lab.

2. Safety goggles must be worn at all times in the lab to prevent eye injuries.  This is not optional.

3. If any chemical has spilled, notify me.  If it has spilled on you, wash it immediately and notify me.  Wash your hands with soap and water after every lab.

4. Do not touch, taste or smell any chemical.

5.  Keep long hair pulled back.  Remove any jewelery or loose clothing before performing a lab.

6.  Do not eat or drink anything in the lab.

7.  Know the location of safety equipment and the first aid kit in the lab.

8.  Do not perform unauthorized experiments in the lab.  Follow all directions carefully.

9.  When using the bunsen burner or hot plates, do not touch beakers, flasks, etc that have been heated.  They are hot!!!!  Always use proper equipment to handle hot objects.

10.  When using eyedroppers or spatulas to transfer chemicals, be sure to return the utensil to the same chemical that it came from.  Avoid cross contamination!

You've watched a pretty cool movie on lab safety.  Your task is to choose one of the 10 safety rules and create a movie using iMovie.  You should have three participants.  Each person should "specialize" in one of three tasks: movie making, acting, scriptwriting.  However, each team member is involved in all three tasks.  You only need to use one iPad for movie making, though, each person may choose to use an iPad for their script.  If you choose to get more involved in using iMovie, there are some great tutorials online (Youtube, etc). 

What Should be in my Science Notebook?

We will keep a science notebook using the Smartnote app.  You may not use this notebook for other classes.  You can create a new notebook in Smartnote for your other class needs.

Things in your notebook include:
-Table of Contents with activity titles and page numbers
-Dates for each activity
-Title for each activity
-Scientific words noted (highlight, underline, circle important terms within your projects!)
-Equations, diagrams and generic models
-Personal reflections
-Warmups and notes
-"Aha!" moments, reflections or questions

In the end, your notebook should be a portfolio of your learning throughout the year.  It is a tool for you to record your work and ideas!

 After today's lab...write about the following in your notebook to record your thoughts!

-How has your thinking changed?...about gum, about your hypothesis, about the lab?
-How has your thinking been reinforced?
-Something I never thought of before this lab is....
-Some questions I have are....
-Next time I will....

Chemistry Phet and Fireworks Lab

*Density Lab: Visit the following link...Density Lab; At this website, you will do an inquiry experiment to examine the relationship between density, mass and volume.
1. In your notebook, describe the relationship between density, mass and volume.
2. In your notebook, create a data table to record observations about the wood, ice, brick and aluminum block. Examine each block in the Density Lab and record observations.
3. Switch the setting to "My block"...and create a new data table or space in your notebook to record multiple experiments with your own concoction. Record any new realizations regarding density in your notebook.
4. Report your findings on your blog in a New Post. (you may access your blog on the right hand side of my blog.)

*Chemical Equation Lab: Visit the following link...Reactants, Products and Leftovers; At this website you will explore balancing chemical equations.
1. Stay at the "Sandwich Shop" tab; Explore making some sandwiches...and looking at your reactants vs. your products. In your notebook, describe how balancing chemical equations is like making a sandwich.
2. Choose the "Real Reaction" tab. Complete each of the equations, "make water", "make ammonia", "combust methane". Create balanced equations, then add more reactants to notice the "leftovers" that are made on the product side from having too many reactants.
3. Choose the "Game" tab. I would stick with the current settings, but feel free to change what you like. Play with the game for awhile. Helpful Hint: you are trying to balance the PICTURE. If you keep getting them wrong...be sure to look at the "leftover" on the right side of the picture. If you are still getting them wrong....ask!
