ISS Student Friendly Learning Target 



Teaching Strategies  Teacher Resources  Student Resources 
Competency Goal 1: The learner will conduct investigations and build an understanding of animal life cycles     

1.01- I can describe life cycles of animals.


(Describe the life cycle of animals including:

  • Birth
  • Developing into an adult
  • Reproducing
  • Aging and death) 

Life Cycle



1.02- I can recognize that insects need food, air, and space to grow.


(Observe that insects need food, air, and space to grow) 


1.03- I can recognize the stages of an insect life cycle.


(Observe the different stages of an insect life cycle) 








1.04- I can compare and contrast life cycles of other living creatures(mealworms, ladybugs, crickets, guppies, or frogs.)


(Compare and contrast life cycles of other animals such as mealworms, ladybugs, crickets, guppies, or frogs) 

Competency Goal 2: The learner will conduct investigations and use appropriate tools to build an understanding of the changes in weather     

2.01- I can see how air moves things.


(Investigate and describe how moving air interacts with objects) 


2.02- I can watch and show how air pushes on things.


(Observe the force of air pressure pushing on objects) 

Air Pressure      

2.03- I can tell how to read temperature, wind direction, wind speed, and precipitation.


(Describe weather using quantitative measures of:

  • Temperature
  • Wind directions
  • Wind speed 
  • Precipitation 




2.04- I can use a wind vane, anemometer, rain gauge, and thermometer.


(Identify and use common tools to measure weather:

  • Wind vane and anemometer
  • Thermometer
  • Rain gauge)

2.05- I can explain how energy from the sun affects land, air, and water.


(Discuss and determine how energy from the sun warms the land, air, and water) 

Water Cycle

Water Vapor



2.06- I can tell how the weather changes through the day and year and why.


(Observe and record weather changes over time and relate to time of day and time of year) 


Competency Goal 3: The learner will observe and conduct investigations to build an understanding of changes in properties 

3.01- I can name three states of matter.


(Identify three states of matter:

  • Solid
  • Liquid
  • Gas) 

States of Matter



3.02- I can recognize changes in states of matter because of heating and cooling objects. 


(Observe changes in state due to heating and cooling of common materials)


3.03- I can tell how heat is made and travels from one object to another.


(Explain how heat is produced and can move from one material or object to another) 


3.04- I can show that solids, liquids, and gases can be sorted by their properties.


(Show that solids, liquids, and gases can be characterized by their properties) 


3.05- I can explain how mixtures can  be put together and taken apart.


(Investigate and observe how mixtures can be made by combining solids, liquids, or gases and how they can be separated again) 





3.06- I can take two materials and make a new material.


(Observe that a new material is made by combining two or more materials with properties different from the original material) 


Competency Goal 4: The learner will conduct investigations and use appropriate technology to build an understanding of the concepts of sound 

4.01- I can make sound by vibrating objects and columns of air.


(Demonstrate how sound is produced by vibrating objects and vibrating columns of air) 




4.02- I can show how to change sounds by making vibrations faster or slower.


(Show how the frequency can be changed by altering the rate of the vibrations) 





4.03- I can change sound by changing the shape or size of instruments.


(Show how the frequency can be changed by altering the size and shape of a variety of instruments) 


4.04- I can explain how my ears hear.


(Show how the human ear detects sound by having a membrane that vibrates when sound reaches it) 


Inner Ear

Outer Ear

Ear Drum


4.05- I can compare and explain how sound is produced by a variety of instruments.


(Observe and describe how sounds are made by using a variety of instruments and other "sound makers" including the human vocal cords)
