1. Topic-
|
Will it sink or will it float?
|
| |
|
2. Content-
|
Important key vocabulary words for the students to know are
-sink
-float |
| |
|
3. Goals: Aims/Outcomes-
|
1. That at the end the children will know the difference between
sinking or floating.
2. That the child will follow directions given to them to be able
to complete this experiment.
3. That the children will be able to work together in groups. |
| |
|
|
4. Objectives-
|
1. After this experiment, the student will be able to tell the difference
in the ideas of sinking and floating.
2. To classify objects into categories, sink or float. |

|
5. Materials and Aids-
|
For this activity, I will need:
-Medium sized containers to hold the water (1 for every group of 4
students)
-a toy metal car
-an apple
-a rock
-a leaf
-an egg
-a paperclip
-glitter
-an eraser
-1 worksheet per child
-a cutout of each item being dropped into the water
-glue |

6. Procedures/Methods-
|
|
A. Introduction-
1.First, I will ask the students to predict what they believe will
sink, and what they think will float. We will chart this on the board
to see if our prediction was correct.
2.I will then say the following: "Today we are going to test a few
objects to see if they will sink or float. Before we do that, what
do you think makes objects float or sink? Do you think it has to do
with its size or what it is made of? Actually, the what it is made
of determines whether or not it sinks or floats!"

B. Development-
1.Then, I will go on to explain the activity by saying" For this
activity, you will each be in groups of fours. Once you are in your
groups, I will then give each of you two items that you will get to
drop into the water to see if it sinks or floats.
2.After putting the children together in their groups and putting
their container of water on the table, I will then give each student
two items to drop into the water. I will also give each student within
the groups a number, so they will know what order to go in to drop
the objects.
3.Then I will explain " Taking turns, each of you will be able to
drop your items into the water. Make sure to leave the items in the
water, so that you can fill out your chart of what items sank and
what items float."
4. I will then walk around the room as the children are trying this
activity, and explain to them why the objects are sinking or floating.
I will go around so I can have a small group discussion with each
group about why they are sinking or floating. |

C. Practice-
1.Once each group has finished, we will then have a group discussion
about what items float or sank, and we will refer back to the original
chart that we made.
2.We will look at the chart, and address which ones were different
from what we originally thought they would do. |

Checking for understanding-
| Once we have had our group discussion, each child will fill out
a worksheet handed to them. In this work sheet, they will classify
what items float or sank by gluing the cutout of the item either under
the water, or below it. |
| |
|
|
Closure-
| To wrap up our activity, we will read the book "What floats? What
sinks? A look at density" that better describes the reason that objects
float and sink. |
