Unit Title: NA Lesson Title: Sink or Float? - Buoyancy

Context

Essential Questions
What is buoyancy? What makes an object sink or float in water? Can we predict the buoyancy
of similar/opposite objects in water?

Objectives
1. Students will be able to correctly define buoyancy.
2. Students will be able to predict if an object can sink or float in water.
3. Students will observe what makes something buoyant or not.

learning.
1, 2, 3       Formative            Students will predict if something is
buoyant and if it will float or sink in water.
The students will need to give reasoning
behind their predictions.
2          Formative           Students will test their predictions and
record if the objects sink or float.
2, 3      Formative     Students will go back over the predictions
and make sense of why things performed as
they did.

Resources, Media and Technology
 tubs for water
 ping pong balls
 golf balls
 paperclips
 craft sticks
 pebble (large and small)
 noodles
 aluminum foil pieces
 cork
 pumis stone
 diet and regular coke
 balls
 wood pieces

Procedures
1. First we will introduce the topic of buoyancy to the students.
2. We will ask the students in groups to come up with a chart describing the objects and
predicting whether the objects we have will sink or float when placed in water and why.
3. We will then have a whole class prediction chart and have the different groups explain
using their prior knowledge about density and buoyancy to explain their predictions.
4. The different groups will test different objects and record their findings in a group chart
explaining why the objects sink or float.
5. We will come back together as a class to share what we found in the class chart and make
sure the students understand the concepts.
6. We will do a few class demonstrations of the objects and share the reasoning.
7. We will have a few extra objects that the class will have to predict and explain.
8. Students will write about their findings in the science journal.
