Growth in Science Teaching (GIST) Activities


Standard I: Students will understand the structure of matter.

Objective 1: Describe the structure of matter in terms of atoms and molecules.

Students probe a clay ball to determine the size, shape and location of an object hidden inside,

thus recreating Rutherford’s efforts with his gold-foil experiment.

  • ILO 1: Use science process and thinking skills.
  • ILO 5: Demonstrate awareness of social and historical aspects of science.

Objective 2: Accurately measure the characteristics of matter in different phases.

Students construct a working definition of density based on their observations and investigations.

  • ILO 1: Use science process and thinking skills.
  • ILO 4: Communicate effectively using science language and reasoning.

Objective 3: Investigate the motion of particles.


Standard II: Students will understand the relationship between properties of matter and the
Earth’s structure.

Objective 1: Examine the effects of density and particle size on the behavior of materials in mixtures.

Students calculate the density of several materials found on Earth.

  • ILO 1: Use science process and thinking skills.
  • ILO 3: Demonstrate understanding of science concepts and principles.

Students use information collected in “Calculating Densities of Earth’s Materials” to predict layering

phenomena based on density differences.

  • ILO 1: Use science process and thinking skills.
  • ILO 3: Demonstrate understanding of science concepts and principles.

Objective 2: Analyze how density affects Earth's structure.

Based on observable evidence, students make inferences about Earth’s internal structure.

  • ILO 1: Use science process and thinking skills.
  • ILO 4: Communicate effectively using science language and reasoning.

To prepare for an understanding of seismic readings and interpretations, students investigate an

object embedded in a clay ball.

  • ILO 1: Use science process and thinking skills.
  • ILO 4: Communicate effectively using science language and reasoning.

Using supplied seismic data, students make inferences about Earth’s internal structure and adjust

the model they developed in “What’s Up Down There?” above.

  • ILO 4: Communicate effectively using science language and reasoning.
  • ILO 6: Demonstrate understanding of the nature of science.

Combining information from the “Layered Separations” activity in Objective 1 above and the model

of Earth’s interior structure developed by the students in the “Earthquake Data Analysis” above,

students make further inferences about the relative densities of Earth’s interior layers.

  • ILO 4: Communicate effectively using science language and reasoning.
  • ILO 6: Demonstrate understanding of the nature of science.

A summative exercise that looks at our current understanding of Earth’s interior structure.

  • ILO 3: Demonstrate understanding of science concepts and principles.
  • ILO 5: Demonstrate awareness of social and historical aspects of science.

Standard III: Students will understand that the organs in an organism are made of cells that have structures and perform specific life functions.

Objective 1: Observe and describe cellular structures and functions.

Objective 2: Identify and describe the function and interdependence of various organs and tissues.


Standard IV: Students will understand that offspring inherit traits that make them more or less
suitable to survive in the environment.

Objective 1: Compare how sexual and asexual reproduction passes genetic information from

parent to offspring.

  • How Many Traits Are There?

Using personal phenotypic traits, students determine their genotypes.

  • ILO 1: Use science process and thinking skills.
  • ILO 3: Demonstrate understanding of science concepts, principles and systems.

Objective 2: Relate the adaptability of organisms in an environment to their inherited traits and

structures.

  • I Will Survive

Students make and hide camouflaged paper butterflies which “predators” then have the

opportunity of finding. The results are graphed.

  • ILO 1: Use science process and thinking skills.
  • ILO 3: Demonstrate understanding of science concepts, principles and systems.

Standard V: Students will understand that structure is used to develop classification systems.

Objective 1: Classify based on observable properties.

Objective 2: Use and develop a simple classification system

Using a variety of beans, students create a dichotomous key.

  • ILO 1: Use science process and thinking skills.
  • ILO 6: Demonstrate understanding of the nature of science.

Objective 3: Classify organisms using an orderly pattern based upon structure
