Testing out a syringe to measure reactant produced.
The British Science week primary pack has an experiment using
- Water
- Sugar
- Yeast
- 3 samples of water at different temperatures
The idea is to determine which produces the best reaction
The experiment uses a balloon to collect the $CO_2$ produced, and uses a tape measure to compare the results.
I am trying to modify this a little to avoid using a baloon, but use a syringe instead.
So the set up I am looking to use has
- Conical flask
- Bung
- Glass tube
- Rubber tube
- Syringe
- Clamp Stand set up to hold the syringe
I have just tested this set up but used Bicarbonate of soda & Citric acid and then added water using a dropper to start the reaction. Putting the bung in quickly so the $CO_2$ doesn't have time to escape. Sure enough the syringe plunger moved as the gas was pushed in.
So the next step is to set this up at the library and use the ingredients above. I plan to set this up before the STEM group on Saturday and observe during the session, which should be over a good few hours. I can then tweak before the next session on March 11th.
