Unit

Through the Looking Glass--LAB

Local Objective

At the end of this lab, students will be able to...

a.  Construct a simple model of a refracting telescope.

b.  Observe distant objects by using the refracting telescope.

Objective used to evaluate students

Yes

Assessment Activity

Informal Evaluations--Teacher will observe during class discussion and questioning.  Teacher will also observe during student making of their "telescope."  Check for students contruction of a simple model of a refracting telescope and their observation of distant objects using their telescope.

Independent Practice--Students will be following the procedure for this activity on their own.  Teacher can make a formal assessment on their work and abiltiy to read and follow directions. 

Assessment:  A final assessment can be made of students final project and their answers to analyzing their results and drawing conclusions.

Learning Activity

The students will:

a.  Review all safety cautions and icons before beginning the lab activity.  Caution:  It is extremely important that students do not look directly at the sun for damage to the eye may occur. 

b. Bring their collection of wrapping paper and toliet paper cardboard tubes to class.  (Teacher will obtain two double-convex lenses per child.)

c.  Follow the procedure outline listed on page 22-23 of the Holt Science and Technology (J) for creating their looking glass. 

d.  Conclude this activity by analyzing their results and drawing conclusions.  During their activity, write down notes about their telescope and their findings; those will be used to analyze and draw conclusions.

Instructional Method

The teacher will:

a.  Guide students during the review of all safety cautions and icons before beginning the lab activity.  Continuously caution students to not look directly at the sun because it could damage their eye.

b.  Help students complete their collection of wrapping paper and toilet paper cardboard tubes.  Bring two double-convex lenses per child.

c.  Guide students in following the procedure outline listed on page 22-23 of their textbook.

d.  Guide students in analyzing their results and drawing conclusions about their telescopes.  Show students how using their notes will help them analyze and draw their conclusions.
