Competency Goal 1: The learner will conduct investigations and build an understanding of animal life cycles.
Objectives

1.01 Describe the life cycle of animals including:

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

1.02 Observe that insects need food, air and space to grow.

1.03 Observe the different stages of an insect life cycle.

1.04 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.
Objectives

2.01 Investigate and describe how moving air interacts with objects.

2.02 Observe the force of air pressure pushing on objects.

2.03 Describe weather using quantitative measures of:

  • Temperature.
  • Wind direction.
  • Wind speed.
  • Precipitation.

2.04 Identify and use common tools to measure weather:

  • Wind vane and anemometer.
  • Thermometer.
  • Rain gauge.

2.05 Discuss and determine how energy from the sun warms the land, air and water.

2.06 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.
Objectives

3.01 Identify three states of matter:

  • Solid.
  • Liquid.
  • Gas.

3.02 Observe changes in state due to heating and cooling of common materials.

3.03 Explain how heat is produced and can move from one material or object to another.

3.04 Show that solids, liquids and gases can be characterized by their properties.

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

3.06 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.
Objectives

4.01 Demonstrate how sound is produced by vibrating objects and vibrating columns of air.

4.02 Show how the frequency can be changed by altering the rate of the vibration

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

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

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