Lesson+Plan

=Title: Exploring Reactions =

=
This lesson will take place after lessons covering physical and chemical reactions, acids and bases, and states and properties of matter. Teacher will place students into groups which will perform experiments identifying & explaining different elements of the experiment as laid out by the teacher. Students will demonstrate the experiment to the class. They will also turn in a report detailing their findings. =====

Objectives:
1) Students will correctly identify each experiment as a chemical or physical reaction with 100% accuracy. 2) Students will correctly identify at least 2 acids or bases. 3) Students will correctly identify at least 3 changes in states of matter from the experiments performed. 4) Students will perform the chosen experiment with the correct outcome.

**<span style="font-family: 'Comic Sans MS',cursive;">Instructional Plans: **
====<span style="font-family: 'Comic Sans MS',cursive;">Teacher will place students into groups of 4 & groups of students will take turns reviewing the wiki site http://exploresciencetoday.wikispaces.com/. For each experiment page, groups will identify whether each experiment is a physical or chemical reaction and why it is such, identify acids and bases involved, and identify changes in states of matter that take place. After this, students will choose one experiment and plan to perform it. They will determine the materials needed and turn in a list to the teacher. The next day, the teacher will provide the group with the proper materials and the group will conduct their experiment outside. Groups will experiment one group at a time, in front of the class, recording the results and explaining the science behind the experiment in their own words. They will also attempt to answer any questions fellow students may have about the experiment. After each group has presented their material to the class, they will turn in their report of the experiment. This report will be due 2 days from the day the experiment was performed. It should include materials needed, procedure, identification of chemical or physical reaction with explanation, identification of any acids or bases present, identification of changes in states of matter, and an explanation in their own words of the science behind the experiment. ====

<span style="font-family: 'Comic Sans MS',cursive;">Adaptation:
====<span style="font-family: 'Comic Sans MS',cursive;">Students are working in groups, so a “buddy” could be assigned to work with a student with special needs. Students with disabilities could turn in a shorter, less detailed report. English language learners may be given more time and may be allowed to research the experiment in their native language for better understanding. ====
