Curated OER
Physical Science- Sink or Float?
Learners investigate which objects sink and which ones float. Learners engage in an experiment, make predictions, and record results on a graphic organizer. This is a comprehensive and easy to follow resource.

Manifest Density
There's a lot content packed into the four lessons of this physical science unit on density. From salad dressing to the water cycle and hot air balloons, these lessons engage students in hands-on activities that explore real-world...
Curated OER
Ice Floats
Students explore the changing density of water. In this physics lesson, students investigate how an object's density determines whether it will float or sink in water. They explain why this unique property of is important to living things.

Sink or Float Water Play Activity
Students experiment with different objects to see if they sink or float. They can also choose certain colored items if more review is necessary.
Curated OER
Liquid Rainbow
Learners develop their own techniques for drawing a small sample of solutions into a straw. They hypothesize ways to increase the density of water, and discuss how salt-free rainwater tends to float on top of salty seawater.
Curated OER
Mountain Barriers
Students examine geographical change. In this mountain barriers lesson, students conduct an experiment to discover how mountains affect surrounding land. Students draw conclusions on how change in land affects plant and animal life.

How Do We Breathe?
Students study the structure of the lungs. In this lung structure lesson plan, students use lung models to study the structure of lungs and experiment to measure the amount of air in the lungs.
