- Good morning class, last meeting I told you to study about the making of your DIY volcano project, right?
- Yes Sir!
- Today, we will have an oral recitation first before you start making your science project.
- 10 ml of dish soap, 100 ml of warm water, 400 ml of white vinegar, food coloring, baking soda slurry, and empty 2-litersoda bottle
- Okay let’s start. The first question is.. what are the materials that are needed to make a DIY volcano?
- Very good, Grace!
- Now, can you give me at least one procedure on making a DIY volcano.
- First, combine the vinegar, water, dish soap and 2 drops of food coloring into the empty soda bottle.
- Second,use a spoon to mix the baking soda slurry until it is all a liquid.
- Third, eruption time! … Pour the baking soda slurry into the soda bottle quickly and step back!
- carbon dioxide, Sir!
- But how does it work? What do you call the gas that was created in a chemical reaction between vinegar and baking soda?
- The gas gets very excited and tries to spread out...
- and what happens if you shake up a soda?
- ...and there is not enough room in the bottle for the gas to spread out so it leaves through the opening very quickly, causing an eruption!
