2. Introduction Student Page Title Introduction Task Process Evaluation Conclusion Credits [ Teacher Page ] In this Webquest you will play the role of the detective as you investigate what occurred the night of the Chemical Reactions Ball. We still don’t know how many casualties there are; however, we know there were both elements and polyatomic ions that walked away from the reactions. Also we already know that the anions were negative and on the right side of the ballroom and the cations were positive and on the left side of the ballroom. Your goal is to understand what exactly happened that night between the polyatomic ions and monatomic ions. How did the compounds react with each other and what should they be charged with for their actions? What signs were there that a chemical reactions occurred? What did the crime scene look like? So far, we suspect the following compounds and elements reacted with each other: Lead Nitrate [Pb(NO 3 ) 2 ] reacted with Sodium Iodide [NaI] Hydrogen Peroxide [H 2 O 2 ] reacted with the catalyst Potassium Iodide [KI Sodium [Na] reacted with Chlorine gas [Cl 2 ] Silver Nitrate [AgNO 3 ] reacted with Copper Metal [Cu] Methane Gas [CH 3 ] reacted with Oxygen Gas [O 2 ] *remember a Catalyst does not react with the reactant, but speeds up the process of the reaction.

6. Conclusion Student Page Title Introduction Task Process Evaluation Conclusion Credits [ Teacher Page ] During this exploration, you learned about five kinds of chemical reactions. These include, but are not limited to: synthesis, combustion, decomposition, single displacement, and double displacement. You also learned how cations react with anions and what products are produced in accordance to The types of chemical reactions. You also reinforced your knowledge of when a chemical reaction occurs using EPOCHL, balancing equations and compounds, and types of bonds between compounds.

9. Introduction (Teacher) [ Student Page ] Title Introduction Learners Standards Process Resources Credits Teacher Page The origin of this lesson came from when I created my first lesson plan in my Practicum I education class. I used the lesson plan to lecture 9 th graders in the class Introduction to Chemistry, Physics, and Earth Sciences at Preston Junior High. The topic was, of course, types of chemical reactions. The teacher wanted me to give a PowerPoint presentation on chemical reactions and to show demos of each reaction during class. She also wanted me to create a lab that the students could do in class. This Exploration was specifically designed for these students in the ICPE class. ICPE is a remedial science class for 9 th graders that didn’t do so well in their 8 th grade science class; therefore, they are learning what they didn’t learn the previous year. The lesson discusses five different kinds of reactions: synthesis, decomposition, combustion, single displacement, and double displacement. The students watch videos and look at notes and their science book to find more information about the types of reactions. After the students get a sense of how each reaction works, they can then predict what the products are of each reaction. Afterwards, the students watch other videos that explain the reactions. The videos demonstrate the reactions and show what specifically happens during the reaction. The students can then use EPOCHL (effervesce, precipitate, odor, color, heat or cold, and light) as traits of a chemical reaction taking place to decide if a chemical reaction did indeed take place.

10. Learners (Teacher) [ Student Page ] Title Introduction Learners Standards Process Resources Credits Teacher Page This lesson could be used for 8 th grade students as well as students of a higher grade. This lesson could also be used for any chemistry class where you think the students would be able to understand these concepts. There is some math involved when balancing the equations and you need to keep that in mind when assigning this Webquest. The students should know how to balance a chemical compound before this Webquest as it asks the students to balance chemical reactions. The student should also have a basic understanding of the terms anions, cations, polyatomic ions, monatomic ions, elements, covalent bonding and ionic bonding, and the difference between a physical and chemical reaction using EPOCHL.

12. The Process (Teacher) [ Student Page ] Title Introduction Learners Standards Process Resources Credits Teacher Page This lesson was organized by the scientific method. The students begin the project with research, predict what they think might happen with the reactions on the introduction page, then they visually qualitatively and quantitatively see what happens to the reactions and record the data, and they draw conclusions based upon what they saw and create visuals to express what they saw happening. The students should be able to get through the videos in one class period and then at home finish writing the report. If they need to see the videos again they will be able to access it on the internet. It should take a week to complete the project upon starting it. This lesson is mulitdisciplinary. The students can be in groups if they want. If that is the case, allow they to create their own groups because then it allows them to be responsible to their own group and they can’t complain if one of their group members is being lazy. The teacher will need to know how to navigate through blogger and know how to use a computer. This lesson is easy enough for a novice teacher as long as the teacher understands the concepts in detail that the students will be learning. The lesson may require for the teacher to know class-management skills if the students become unfocused. Variations The lesson can be taught in class as supposed to a computer lab. They teacher could do the reactions in class as demos and then the students would still be able to see the reactions occurring. If the teacher is uncomfortable with doing demos in class they could show the videos to the students on a projector. Evaluation Teacher Script Conclusion Student Process Page

14. Evaluation(Teacher) [ Student Page ] Title Introduction Learners Standards Process Resources Credits Teacher Page In order for this lesson to be successful, the students must create reports that give accurate accounts of each types of chemical reaction and correctly answer the questions given to them. The students should also be as creative as possible and enjoy the project. Additionally, the lesson is successful if the project is easy for the students to understand what is asked of them. An exemplary project is one that correctly describes all the types of reactions as well as the reactions on the introduction page. They need to have all the questions correctly answered and create a visual and investigative report that is very colorful, understandable, and sophisticated. This, of course, should be tightly related to the standards and objectives you cited above. Evaluation Teacher Script Conclusion More than 4 errors in spelling, punctuation and grammar in the report.

16. Conclusion (Teacher) [ Student Page ] Title Introduction Learners Standards Process Resources Credits Teacher Page This lesson gives students a creative means to learn about types of chemical reactions. It is not a lab report, but an investigative report. The lesson, also, directs the students to different concepts that relate to the types of chemical reactions and the students are forced to make connections between these different concepts and the chemical reactions. Hopefully, the students will remember this project when they go on to higher level chemistry classes. It will be important to know this information because it creates the foundations needed for these harder chemistry classes. Evaluation Teacher Script Conclusion
