CHEMICAL REACTIONS: COLOR, FOAM, and FLUFF Lauren Hawkins, Karen Yuhas Booth, Venzella Stowers, and Eric Davis Piedmont College Running Head: CHEMICAL REACTIONS: COLOR, FOAM, and FLUFF The theme and topic of the final project was “Color, Foam, and Fluff.” This topic explains the three different types of scientific chemical reactions. The project discussed the three 2 types of chemical reactions, which are; volatile, size and state, and avoidance reactions. In order to explain these types of reactions experiments were done that consisted of placing Mentos in diet coke, producing “magic snow”, and placing soap and food coloring in milk. The experiment of placing Mentos in diet coke gave a visual explanation of volatile reactions. Volatile reactions are described as “an evaporating effect that takes place at normal temperatures and pressures, which can readily be vaporized. During the experiment, four different types of soda were used to determine which combinations of ingredients provided the most effective result. When the Mentos was placed in the soda, an expansion of the carbonation occurred, which caused an explosion, sending the soda out of the bottle and several feet into the air. The next experiment that was conducted was creating “magic snow.” This type of experiment was conducted by combining sodium polyacrylate and water. This type of experiment provided a visual example of both size and state reactions and rapid absorption. Size and state reactions increase in volume, rapid absorption, and changes from hard to soft or from a soft to a liquid. The more water that was used increased the overall volume of the “snow.” The sodium polyacrylate absorbed the water and changed its molecular structure which produced the white powdered snow. Finally, the avoidance reaction helps the cell move and can cause other objects to bounce off of the cells outer membrane. This type of reaction was explained by utilizing the experiment of placing soap in milk that had been mixed with food coloring. By placing liquid soap in milk, Running Head: CHEMICAL REACTIONS: COLOR, FOAM, and FLUFF the fatty molecules in the milk are separated and pushed away. The reasoning for the food coloring was to provide a visual of this occurrence taking place. 3 The State standard that was utilized was standard S5P2, which states that “students will explain the difference between a physical change and a chemical change”. It was recognized that the properties of these substances used in each of the three experiments changed during and after the experimental process. Each of these experiments was videotaped to provide visual examples of what took place during the entire process. The lesson plan that was chosen for this project was the UBD, or Understanding by Design lesson plan. This type of lesson plan utilizes visual learning, which was needed to fully understand the reactions that took place in the three experiments that were conducted. This lesson plan also helps to establish goals, provides essential questions, and utilizes technology during the entire leaning process. This lesson plan is also quite formal and has an easy to understand layout. The target audience for this project is fifth grade students. This is due to the fact that the reactions that were caused by these experiments are for higher elementary educations. Another reason for the target audience being fifth graders is that level of education, vocabulary skills are rapidly expanding, and attention spans are rapidly decreasing. This causes teachers to work harder and come up with fun and exciting ways to teach their students rather than using the age old chalk board, or dry erase board. These experiments do just that by bringing the students into an outside environment, allowing group work, visual aids, and hands on learning for the kinesthetic learners. Running Head: CHEMICAL REACTIONS: COLOR, FOAM, and FLUFF The types of technology that are being attempted to integrate into the lesson plan are; PowerPoint, SmartBoard activities, video clips, and concept maps. The first step was 4 providing a concept map of the project, which provided an order of events and main ideas. This was done so that each individual is aware of what is going to be discussed. The next step was to form a story board, which is utilized by PowerPoint. The PowerPoint outlined the main ideas that the group was wishing to incorporate and the order of events in a more story telling setting. Finally, videos and SmartBoard activities were designed in order to provide interaction not just with the teacher and students but student to student interaction as well. This type of interaction would hopefully allow the students to become more engaged on the subject and learn at a faster and more consistent level. This project was done with the idea of it being for a future teaching situation. This is due to the fact that fifth grade classrooms were not utilized during the experiments to determine if this would be an effective teaching mechanism. It is also unknown if the students would even enjoy this type of learning environment. It is quite possible that some classrooms are using this type of learning at the present time, but as for this project, this will be for future teaching endeavors. Initial ideas were constructed for arranging the group’s plan and materials on a website that can be utilized by teachers, students, and their parents. The plan and materials are based on explaining the terms and reactions in a manner that everyone can understand, and where easy and effective learning can be achieved. This site would in turn be a site that would provide more fun and easy experiments that can be performed and can allow the student to think of other possible experiments that could be done. Running Head: CHEMICAL REACTIONS: COLOR, FOAM, and FLUFF These experiments conducted by the group utilized higher learning of volatile reactions, size and state reactions, and avoidance reactions. These experiments can be done in either a 5 classroom setting or in an outdoor setting, can utilize hands on learning, and teamwork, which can help with the decreasing attention spans of the students. The group also utilized these projects because they not only utilize the previously stated aspects, but also can utilize technology such as video, SmartBoard, and internet during the education process, and can even bring the parents of the students into the learning process as well. Overall, these experiments provide a great example of types of learning that can be utilized to engage the minds of students better than sitting in a desk looking at a chalk board for an entire day. Students will be familiar with the character of scientific knowledge and how it is achieved. Students will recognize that: › Similar scientific investigations seldom produce exactly the same results, which may differ due to unexpected differences in whatever is being investigated, unrecognized differences in the methods or circumstances of the investigation, or observational uncertainties.
