Learners define and discuss salinity, conduct classroom experiment to determine salinity of water sample by using hydrometer, record predictions, and demonstrate understanding of how salinity influences object's ability to float in water.

Students complete a science experiment to study insulation, heat transfer, and permafrost. In this permafrost study lesson, students design and test a soda insulator. Students graph their class data and discuss the results. Students...

Students follow this recipe for fun clay creations. In this early childhood art and science lesson, students develop creative-thinking skills, fine-motor skills, and sensory awareness while they make, mold, and decorate salt dough.

Students learn about snow. In this snow themed lesson plan, students read a book, make a painting, and observe snow. A math activity timing how long it takes for snow to melt is included.

Students study the properties of the physical and natural world. In this properties of the physical and natural world lesson, preschool students work at discovery tables to see how simple machines work, what happens when items are put...

Students explore various animal brains. In this animal anatomy lesson, students compare and contrast animal brains with the brain of a human. They record several characteristics in a data table for each brain they observe.

Fourth graders taste different flavors on their popcorn. In this taste bud lesson, 4th graders make predictions about taste and dip popcorn into four different flavors. They record how the flavors tasted - sweet, salty, bitter, or sour.

Fifth graders are presented with three rocks and a variety of tools and are asked to investigate the properties of the rocks to see which rock is best for building tables and benches for a museum picnic area.

Students examine the effects of acid rain by performing a simulation experiment. They also view the effects of acid rain and erosion on the reservation and record observations in a science log.

Students build a model aquifer to study groundwater zones and water table formation. Students use the models to measure the movement of polluted groundwater.

Students investigate water usage at school and at home. They use graphs and tables to evaluate water usage. Students describe possible water conservation measures. They use graphs and tables to relate data as part of a written report.

Second graders conduct investigations to explore matter. In this states of matter lesson, 2nd graders complete four activities to analyze the three states of matter. Students analyze the properties of solids, liquids, and gases. Students...
