S+3.2.2+Lesson+2

= LESSON PLAN = created by: Eagle Valley and Foothill 1st Grades

__Core Objective/Standard__:
Standard 3: Physical Science Objective 2: Analyze objects ad record their properties.

__Student learning objective__:
Students will predict the weight of an object when compared to a standard object

__Materials needed__:
1 Standard object per group (i.e--Pink Pearl Eraser, box of crayons, bottle of glue) 1 balance per group a collection of objects of different weight from your classroom that can fit on your balance (i.e.--markers, blocks, unifix cubes, small books, pens, pencils, paper clips, water bottles, etc) 1 copy of Heavier and Lighter recording sheet for each child

__Teacher (To) directions/actions/instructions__:
Demonstrate how to predict whether the object will be heavier or lighter. Demonstrate how to use a balance to compare weights. Students will always be comparing the weight of the collection of objects to the standard object.

Use the vocabulary: predict, conclusion, data

__Teachers/Students (With) actions__:
Make predictions together on whether one of your collection objects are heavier or lighter than your standard objects. Show and do on the recording sheet how to first circle prediction and check it.

__Students (By) actions/activities students will do during lesson__:
Put students in groups of 2 or 3. Have them record on the Heavier and Lighter recording sheet as they use balances to compare collection objects to standard object.

__Assessment-these may be written, verbal, observations, etc__:
Listen to student vocabulary. Are they using predict, weight, conclusion, and data? Are students recording properly?


 * Old investigations lesson in "Bigger, Taller, Heavier, Smaller" on weight comparison is very similar and has additional activities
