Learning Experience 5E Component Identify the 5E component addressed for the learning experience. The 5E model is not linear. Details Science and Engineering Practices ☐Engagement x Exploration ☐Explanation ☐Extension ☐Evaluation Materials:(for each lab group of 2-3 students) erlenmeyer flask balance weighing dish two reactants balloon hot plate hot hands or flask tongs For the reactants are many different chemical reactions that can be used for this investigation and calculation. One good combination is acetic acid (vinegar) and sodium bicarbonate (baking soda). If another reaction is selected, check the safety of both the reactants and products, and be sure that evaporating the liquid solution that remains by using a hot plate will not product a hazardous condition in the laboratory. Preparation: Be sure to test out the ratio of acetic acid to sodium bicarbonate to make sure the gas produced is enough to partially fill the balloon but not pop the balloon off of the flask. Students will be calculating the quantities of each reactant to use, but depending on the concentration of acetic acid you are using, you need to limit the quantity of one of the two reactants to avoid having the balloon overfill and pop off of the flask. Facilitation of Learning Experience: Introduce students to the erlenmeyer flask if students have not previously used them, and demonstrate the technique of putting an empty balloon over the mouth of the flask before mixing the chemicals. The Asking questions (for science) and defining problems (for engineering) Developing and using models Planning and carrying out investigations Analyzing and interpreting data Using mathematics and computational thinking Constructing explanations (for science) and designing solutions (for engineering) Engaging in argument from evidence Obtaining, evaluating, and communicating information
