Either Wednesday or Friday you will be demonstrating the properties of water to the class in a hands on activity. You can work in groups of four or five.
Some properties to think about are adhesion, cohesion, thermal properties, surface tension, universal solvent, and conductivity.
youtube.com is a great resource to get ideas that you would like to present to class.
1. You need to write at least a three sentence typed short story about the Elephant Toothpaste experiment. You need to hand it in through the google forms to get credit.
-you need to have the reactants and products of the reaction
-you need to describe what happened and how the experiment evolved
-you need to use the ABT "and but therefore" method of story telling.
-grammar needs to be proper
Down Load Clean Swell App and go to the Maui Huliau Beach Clean up or another beach clean up this weekend and take a screen shot of the results you make. I also need a group photo of you cleaning up the beach.
Answer the questions without looking at the answers. Then check to see if your answers are correct. This will prepare you for the mini information festival on Wenesday 9/14/2016
1. If you were a superhero what three super hero powers would you want? List them from your most important to least important. Why did you choose these super powers?
2. Name your super hero using symbols from the periodic table. See photo for example
3. How many grams does one mole of all the elements in your super hero name weigh?
Ex. H2O = 2 (1.008)+(15.994)=18.01g/mole of water
4. What properties do several elements have that are similar to your super hero powers? Make a list of at least four elements and explain how they match.
5. Create a Symbol for your Super Hero.
Try to use and modify a symbol that represents one of the elements you used in the previous questions. You can find the symbols using the following interactive periodic table.
Use the interactive periodic table to help examine different elements.
Compare and Contrast your “change” battery to a marketable battery such as an LED battery or a salt water battery.
Include a diagram for your battery and a diagram for the battery of comparison.
What do you think the difference between the distilled water and saturated salt water would be?
How do you think the Vinegar affected the pH of the water?
How many pennies do you need for your LED to work and why?
What could go wrong or what did go wrong?
How did you trouble shoot your battery?
Show your parents your “change” battery. Upload a picture to google drive and share it with me through the form fill.
