Hydro Electric Generator Challenge

Reaction Products Investigation

What do you think you will see in your evaporation dish tomorrow? How will you determine if the white precipitate is baking soda or some other substance?

Chemical reaction investigation

Where did the bubbles come from in cups 1 & 3?  What was the solid that formed in cup 1?

Wrap Up Questions

1.  What happened to the bag?
2.  What made the bag puff up like a pillow?
3.  Where did the gas come from?
4.  What did you find out by doing the reaction in a bag that you couldn't find out doing the reaction in a cup?
5.  How much gas formed as a result of the reaction?
6.  How does the volume of gas compare to the volume of substances you put into the bag?
7.  How did the reaction differ between the 2 bagged experiment?
8.  Which reaction produced more gas?
9.  What happened when we put all 3 reactants in the bag and added water?

Mystery Solutions

What was the same for each solution?  How did you determine if the concentrations were the same or different for each of the solutions?

Roller Coaster Progress

Concentration Lab

Why was it important to take repeated measurements of our solutions?

Our 1st Science Olympiad

Lizard!!!

Extra credit....first student to identify this lizard, tell me what it eats and its ideal habitat.  Ready...GO!!!

Tornado in Lincoln!

Here's a picture of a funnel cloud my son took at baseball practice tonight...

KoolAid Recipe?

Were all the solutions we made today the same?  Was the concentration of each solution the same?  Were some solutions more diluted than others?  How could you tell?  What was the solvent and solute?    

Magic Multiplying Salt???

Explain why, as a class, the mass of the salt increased.

Separating Salt Solution

What do you predict you will see in your evaporation dish tomorrow?

Just for Fun :)

Making a Solution

In today's lab, which of the measurements were direct and which were derived? What other examples can you think of for direct and derived measurements? Why do you think we saw such a variance in our measurements today? What did your measurements prove in terms of the final mass of solutions?

How does Earth's Water Compare?

Jumping Penny

What principle helps explain how you were able to move the penny into the container/over the counter without touching it?  Explain how this works.

Robot Practice...Science Olympiad

Drop!!!

Thanks Mr. Smith!!

Saturation Lab

What was the solute, solvent, and solution in today's lab?  How did you know that your solution became saturated?  Was your prediction accurate?
