Students use hands on scientific observation to determine characteristics of wood. They work directly with the materials and record their observations. Students test if wood absorbs water, if wood floats or sinks, and if all wood...

First graders develop skills of scientific inquiry. They determine which objects float and which sink.

Students examine how density is a value that describes what type of a material an object is made of regardless of its shape or size.

Students discover how seeds travel from their parent plants in search of water, sunlight, and nutrients, and conduct experiments in which they note characteristics that encourage seed dispersal by means of wind, water, animal carriers,...

Students participate in a demonstration to test the different densities of plastics, and suggest a method that plastic waste can be separated and collected.

Students work together to create a watershed model. They discover the flow of surface water on different topography. They examine how materials originate from miles away and end up in a different wetland.

In this instructional activity, students will listen to nonfiction books about items that sink and float. Students will participate in filling in words to fill in a teacher-created chart that is connected to the information. Students...
