# Lessons

 Date:      Monday 8/15/11 Objective: To learn the classroom rules, procedures and expectations for the upcoming school year. Lesson or  Lab Activity: Arkansas Frameworks:

 Date:     Tuesday 8/16/11 Objective: To understand that science is built on evidence that can be observed or deduced from the natural world.  To learn to discern between useful and useless data. Lesson or  Lab Activity: Checks lab – students in groups of four will choose four checks from an envelope at random and determine the circumstances that surround the writing of the checks.  They will discuss their observations and form a hypothesis based on the observable data.  They will then draw four more checks with new information and revise their hypothesis based on the inclusion of the new data.  The group will then draw two more checks from a final envelope and revise the hypothesis again.  Each group will select a spokesperson that will give present the group’s conclusions to the class. Arkansas Frameworks: NS.1.8.1 Justify conclusions based on appropriate and unbiased observations NS.1.8.6 Formulate inferences based on scientific data NS.1.8.7 Communicate results and conclusions from scientific inquiry following peer review

 Date:      Wednesday 8/17/11 Objective: To use the scientific method to construct a foil boat design capable of holding as many pennies as possible without sinking. Lesson or  Lab Activity: Building penny boats lab:  Working in pairs, students will measure and cut three 10 x 10 centimeter squares of foil.  Students will discuss and draw three potential models that they think will work best.  Those three boat designs will then be constructed and tested.  Students will use the number of pennies each boat will hold to collect data and test their hypothesis for each design. Selection of the best design as well as design flaws will be discussed in the students’ conclusion. Arkansas Frameworks: NS.1.8.1 Justify conclusions based on appropriate and unbiased observations NS.1.8.3 Formulate a testable problem using experimental design NS.1.8.6 Formulate inferences based on scientific data NS.1.8.7 Communicate results and conclusions from scientific inquiry following peer review

 Date:  Thursday 8/18/11 Objective: To learn how to classify objects by observable charcteristics. Lesson or Lab Activity: Students will work in groups with bins of seashells. Each group must sort and classify the shells by characteristics determined by the group.  After all groups are finished, each one will present their classification system to the class. Arkansas Frameworks: NS.1.8.1 Justify conclusions based on appropriate and unbiased observations NS.1.8.7 Communicate results and conclusions from scientific inquiry following peer review

 Date:  Friday 8/19/11 Objective: To learn how to use a dichotomous key.  To read and discuss safety contracts. Lesson or   Lab Activity: Students will work in pairs and use a dichotomous key to sort and classify ten types of wetland habitats.  The class will then discuss the activity as a whole group to check accuracy of student classification.  After completing the activity, the class will go over the lab safety rules and contract. Arkansas Frameworks: LS.2.8.5 Use a dichotomous key
