Life Cycles, Measurement

West Haven Public Schools

Unit Planning Organizer

Subject:  Science

Grade:  1

Unit:  1.3  Life Cycles,  Measurement GLE #1 (length & weight)

Pacing:  April - June

Essential Question(s):

1.      How do you grow and change?  (infant, toddler, child, adolescent, adult, elderly adult)

2.      How does (an animal that undergoes metamorphosis) grow and change?

3.      How does (an animal that does not undergo metamorphosis) grow and change?

4.      What can you use to measure how long a ________is?

5.      What can you use to measure how much a _____ weighs?

 

Big Idea(s):

1.  Living things change as they grow in their life cycle.

2.  There are many different ways to find the size and weight of things        

      so we can better describe them.

 

 

CT State Standards (includes West Haven’s “Priority” GLES’s in BOLD and “Supporting” Standards)

Priority Standard

 

Science 1.3  Organisms change in form and behavior as part of their life cycle

 

# 1 Explain that living things experience a life cycle that includes birth, growth,    reproduction, and death.

#2  Distinguish between animals that are born alive (e.g. humans, dogs, cows) and those that hatch from eggs (e.g. chickens, sea turtles, crocodiles)

# 3  Compare/Contrast the changes in structure and behavior that occur during the life cycles of animals that undergo metamorphosis and those that do not.

#4  Analyze recorded observations to compare the sequenced metamorphosis stages of different animals, and make predictions based on observed patterns.

 

Science 1.4  The properties of materials and organisms can be described more accurately through the use of standard measuring units.

 

#1.  Use nonstandard and standard measurements to describe and compare the weight, length, and size of objects and organisms.

#2  Show approximate size of a centimeter, meter, inch, foot and yard using referents such as a finger, a hand, or a book.

#3  Use metric and customary rulers to measure length, height, or distance, in centimeters, meters, inches, feet, and yards.

#4  Use balances and scales to compare and measure the heaviness of objects and organisms in kilograms, grams, pounds, and ounces.

 “Unwrapped” Concepts and Skills, and Bloom Levels (BL)

Concepts(Need to Know)

Skills(Able to Do)

BL

1.  Life cycle of living things –

     *birth, growth, reproduction    

       and death

 

2.  Changes in structure and        

      behavior occur during    

      the life cycle of animals

 

3.  Weight of object or  

      organism -

     *kilograms

     *grams

     *ounces

     *pounds

 

4.  Length/height or distance of

      an object or organism -

     *centimeter

     *meter

     *inch

     *foot

     *yard

Assessments

Common Formative Pre- Assessment (Followed by Data Team Analysis):

Use a KWL chart (Know, Want to know, Learned)  Life Cycles,

Order life cycle pictures

 

Oral assessment for measurement

 

“Dipsticks” (Informal Progress Monitoring Checks):

1.      Observations of student progress

2.      Oral assessments

3.      Informal questions and answers

4.      Supplemental worksheets (not for measurement)

 

Common Formative Post- Assessment (Followed by Data Team Analysis):

Post Test (attached) 

Instructional Planning

Suggested Resources/Materials:

*Life cycle teaching charts

*Non-fiction leveled readers

*Ruler, yardstick, meter stick

 

Suggested Research-based Effective Instructional Strategies:

1.      Whole group instruction

2.      Small group and/or partner experimentation

3.      One on one instruction and reinforcement by paraprofessional

4.      Science manipulatives
