Nature Exploration: Discovery

August-June

This program engages students in a hands-on exploration of Ohio’s natural areas.  We will focus on building identification and classification skills and applying them to learning about our environment.   This is an ideal program for a first time visit to Greenacres or for students to become more comfortable in nature.

Ohio Science Standards:

  • SIPA Grade 3-5: Observe and ask questions about the world that can be answered through scientific investigations.
  • SWK Grade 3-5: Science is a way of knowing about the world around us based on evidence from experimentation and observations.
  • 4.LS.1: Changes in an organism’s environment are sometimes beneficial to its survival and sometimes harmful.

NGSS Standards:

  • 4-LS1-1. Construct an argument that plants and animals have internal and external structures that function to support survival, growth, behavior, and reproduction. 

Vocabulary:

observation, discovery, classification

Fossils

August-June

Take a look at the history of Ohio’s land through its ancient ancestors.  Learn about a distant past where Trilobites ruled the warm waters of the Ordovician sea. Investigate how fossils are formed and what was left behind for us to find here at Greenacres.

Ohio Science Standards:

  • LS Grade 4: Fossils can be compared to one another and to present day organisms according to their similarities and differences.

NGSS Standards:

  • 4-ESS1-1. Identify evidence from patterns in rock formations and fossils in rock layers to support an explanation for changes in a landscape over time.
  • 4-ESS2-1. Make observations and/or measurements to provide evidence of the effects of weathering or the rate of erosion by water, ice, wind, or vegetation.

Vocabulary:

erosion, deposition, sediment, Ordovician fossils, glacial erratic, limestone, shale

Erosion and Weathering

August-June

In Ohio, our rivers and streams tell a story. Changes in the landscape are caused by weathering of rock and soil, and by transportation and deposition of sediments. Students will explore the process of erosion and look for signs of weathering here at Greenacres.

Ohio Science Standards:

  • ESS Grade 4: Earth’s surface has specific characteristics and landforms that can be identified.
  • ESS Grade 4: The surface of Earth changes due to weathering.
  • ESS Grade 4: The surface of Earth changes due to erosion and deposition.

NGSS Standards:

  • 4-ESS1-1. Identify evidence from patterns in rock formations and fossils in rock layers to support an explanation for changes in a landscape over time.
  • 4-ESS2-1. Make observations and/or measurements to provide evidence of the effects of weathering or the rate of erosion by water, ice, wind, or vegetation.

Vocabulary:

erosion, weathering, deposition, sediment, landform
