Have your class predict whether objects will sink or float in water. Learners consider a data table of mass, volume and whether the object sank or floated. They develop an evidence-based explanation for the results.

Students explore sinking and floating.  For this buoyancy lesson, students conduct an investigation dealing with regular and diet soda. Students drop various soda cans into water and then discuss why some float and some...

Students will determine whether various objects sink or float in water. They do not need to explain why objects sink or float. They are rather to be encouraged to observe that the same objects will sink or float every time, i.e., that...

Students explore the concept of floating objects (ice).  In this floating lesson, students conduct an investigation in which they hypothesize about the time that an ice boat will last floating in water.  Students record their...

Young scholars use their background knowledge of how scientists work to discuss and predict if a given object will sink or float. They record their predictions on a data sheet. Students test the objects and organize them into floating...

Pupils design a craft that safely floats vegetables across a classroom. The teacher provides some materials, but the child may as well. As the experiment is created, they have to fill out worksheets to keep the actiivity organized. After...

Students predict whether objects will sink or float in water. They classify objects as sinking or floating in water. Students identify and explain similarities between objects that sink and float.

Students have seen that solids, which are more dense than a liquid, that sinks in that liquid and solids, which are less dense than a liquid, that floats on that liquid. They use a metal boat to float in water. Pupils comprehend that...

This lesson plan is designed to have young children explore the concept of sinking vs. floating by using the skills of prediction, observation and classification.
