Procedure: Try these combinations: Liquid Additive Water Epsom salt Hydrogen Peroxide Yeast Vinegar Baking Soda Epsom salt and water Measure out 80 mL of water using a graduated cylinder, pour into a 250 mL beaker. Use a thermometer to record the water’s initial temperature and record in the table below. Measure 25 grams of Epsom salt. Use a stirring rod to dissolve the Epsom salt in the water. Record the solution temperature in the data table below every 20 seconds for three minutes. Hydrogen peroxide and yeast Measure out 60 mL of hydrogen peroxide using a graduated cylinder and pour into a 250 mL beaker. Use a thermometer to record the hydrogen peroxide’s initial temperature in the table below. Measure out 6g of yeast. Use a stirring rod to dissolve the yeast in the hydrogen peroxide. Record the solution temperature in the data table below every 20 seconds for three minutes. Vinegar and baking soda Next, measure out 50 mL of vinegar with a graduated cylinder and pour into a 250 mL beaker. Use a thermometer to record the vinegar's initial temperature. Record in the table below. Measure out 4g of baking soda. Use a stirring rod to dissolve the baking soda in the vinegar. Record the solution temperature in the data table below every 20 seconds for three minutes. Graph your data using different colors for each process. Don’t forget all the components of a graph that we have talked about!!
