Classroom Resources | Chemistry in a Bag | AACT Measure 30 mL of distilled water and pour it into bag 1. Repeat for bags 2-4. Add 5 ml of the universal indicator to each bag. Note the color in your data table. Squeeze out the any excess air and seal the bags. Measure 1 gram (or use 3 nuggets) of Calcium, and add it to bag 1. Make sure the bag is tightly sealed. Chemistry in a Bag - The Art of Teaching Science Inquiry Procedure 1. Measure one spoonful of calcium chloride and place it into the ziplock bag. 2. Add one spoonful of sodium bicarbonate (baking soda) to the bag. Zip the bag closed and shake it to observe for any evidence of a chemical change. 3. Pour 10 mL of cabbage juice into a small vial. Chemistry in a Baggie | Central Coast Science Project ... This is a chemical change that produces no heat but does result in an acidic solution, so the cabbage juice turns pink. The acidic protons also react with the bicarbonae ions to make water and carbon dioxide gas, which inflates the bag. This chemical reaction also pulls in heat from the surroundings, so the bag becomes cold as well.

In this project, safe materials are mixed to change colors and produce bubbles, heat, gas, and odor. Explore endothermic and exothermic chemical reactions and help students develop skills in observation, experimentation, and inference. Chemistry in a Bag - STEM-Works Students will learn all about the concepts of chemical reactions. Worksheets are provided along with the activity to assess what they observe, and what they learned from the experiment. Do this activity. PDF Chemistry In a Bag - Weebly Chemistry In a Bag Science & Matter Purpose: To make observations and inferences; and to design an experiment in order to isolate variables. Materials: · Your Lab Notebook · Scoopula · Goggles · Balance · Zip lock bag · Weigh paper · Sodium bicarbonate · 10 ml graduated cylinder Reaction in a Bag - The Wonder of Science Reaction in a Bag. Description: This video shows a chemical reaction of sodium bicarbonate (baking soda), calcium chloride (road salt), and an indicator phenol red. The chemicals react to form calcium carbonate, sodium chloride, and carbon dioxide gas. This changes the pH inside the bag resulting in a color change in the phenol red.
