it doesnt really matterr that much... its going to go over the side anyway. the bigger the reaction you want, the more you put in.
baking soda and vinegar put the baking soda in first
Because people put in baking soda, vinegar and red food coloring in the volcano. The baking soda and vinegar makes it explode
That really depends on how big your volcano is. If you want a nice big explosion fill your volcano up about 1/3 full with baking soda but measure out how much baking soda you used, then add some food coloring to the vinegar and pour the same amount of vinegar as baking soda into the volcano. REMEMBER: Pour the vinegar in quickly otherwise it will start spilling out all over before you even get all of the vinegar in. Now stand baack and watch your volcano go!
Baking soda and vinegar is the standard way of making a papier-mache "volcano" for a child's science project. The reaction between baking soda and vinegar is immediate and can be quite intense. Too much baking soda and too much vinegar can make the "lava" erupt to the ceiling of the classroom!
The control group is the vinegar and the volcano
well, the chemicals and molecules in the baking soda and vinegar causes them to react with each other.
vinegar and baking soda
i think baking soda but don't use a combination of vinegar and baking soda or else you will get a volcano eruption =) hope this helps Katie xxx
vinegar or baking soda
nothing
The vinegar-baking soda reaction is a chemical change.
EX: "I can predict that the baking soda will react with the [vinegar] violently and will produce a foaming effect and will emerge from the volcano rapidly"
