Molecular Polarity Lab Report

Acid and Base Intro

Fireworks and Phet: Part 2

1. Complete the Fireworks Lab from last week, and post your final summary to your blog.
2. Go to the Salts & Solubility Lab. Stay on the "Table Salt" tab. Answer the following questions on your blog.
A. Table salt is made up of what two elements?
B. What happens to a molecule of table salt when it enters water?
C. Describe the following terms and discuss how they relate to the tutorial: solution, solute, solvent, concentration.
D. Add a lot of salt to the water. Describe what happens with the amount dissolved vs. the amount bound. How could you increase the amount dissolved?
E. Switch to the "Slightly Soluble Salt" tab. Choose a salt and compare the maximum amount dissolved to table salt. (be specific!)
3. Go to the Acid-Base Solutions simulation. Complete the data tables and questions provided.
4. If you finish early, create a glogster showing your work on fireworks. Include information from your notes, your last post, and the lab we performed last week.

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!

*Visit Nova Fireworks
1. Click on "Name that Shell" and view videos 1-6 using Quicktime. Describe each type of firework in your notebook.
2. Click on "Anatomy of a Firework" (choose the one requiring Flash). View and read about each part of the firework.
3. Click on "Pyrotechnically Speaking" and read the 2 PART interview. Take some notes on the most interesting parts in your notebook.
4. Click on "On Fire" (choose the Flash version). Complete the game (you must read the directions!)
5. Write 2 reflection/summary paragraphs about fireworks and what you have learned on your blog. Use your notes to help you!
