Chemical Reactions!

 In science class we learned the scientific method through experimentation. This was a more effective and fun way to teach about the steps of the scientific method. We started the chemical reaction experiment with three different ingredients: baking soda, calcium chloride, and phenol red.




For the first experiment we were given a specific recipe to follow. This recipe was 2 scoops of calcium chloride, 1 scoop of baking soda, and 10 mL of phenol red.

We measured each one of these ingredients out and poured them into a ziplock bag.

As soon as all of the ingredients were in we sealed the bag and mixed the ingredients.

When all of the ingredients were mixed we got to see a chemical reaction. The mixture started to produce gas bubbles and heat.

After seeing this reaction we were given the chance to try and produce a different chemical reaction. We tried to create a mixture with more gas bubbles. To do this we created a mixture with 1 calcium chloride, 2 baking soda, and 10 mL phenol red. When this did not give us the reaction we wanted we tried a mixture of 2 calcium chloride, 1 baking soda, and 10mL vinegar. The vinegar mixture gave us significantly more heat and bubbles from the reaction. This experiment would be a great one to do with students in the classroom because it is easy to do and it allows the students to use the steps of the scientific method to try to make their own mixtures.
