Based on an experiment from Janice Van Cleave 

*Predictions/Hypothesis (What do you think is going to happen?)

• I think when you mix them together they will explode because of the alka seltzer. Celine 
• I think the water is going to fizz and make colored bubbles.
• I think bubbles are going to fizz up.
• I think the alka selter is going to blow up. Rick
• I think the water is going to bubble and turn red.Elizabeth

 Procedures (What you observed or did during the experiment)

• 1. Use a plastic soda or water bottle (16 to 20 oz).
• 2. Pour one cup of water into the bottle.
• 3. Add 10 drops of food coloring-swirl the bottle to mix.
• 4. Fill the bottle with cooking oil to height shown in diagram.
• 5. Break an Alkaseltzer tablet in half. Drop one of the pieces into the bottle. Make observation. 

 Observations/Data (What happened as a result of your procedures)

•   When I pourd the oil and the food coloring into the bottle it didn't mix and the oil stayed at the top.
• The liquid vibrated in the bottle because it has less mass.     
• The water was at the botle was at the botom because it was heavier.
• When we put the alka seltzer in the water it bubbled up.

*Results  (Why you think what you observed happened...in your own words)

• I think the liquid bubbled up because The sodium-carbonate releases a gas or air will make it bubble up.
• When Mr.Parker put the Alka-selter in the water bottle the water started to fiz. 
• I think the water bubbled up and down because when the alkasetzer is put in the water the bakingsoda and citric acid react to form gas bubbles.  

*Conclusion  (What actually happened...use vocabulary learned)

  Further Research/Questions (For extra credit unlsee assigned...any further questions?  Or go on the internet, research the topic, and teach us something!) 

•  What will happen if we put more than one alka selzter?Elizabeth
• Sodium bicarbonate is used to reduce stomach acids , treats heart burn, indigestion, stomach disorders, and kidney disorders.nick
• What will happen if you only put water,oil,and the alka selzer? Destiny
