coordinating with objects on the sheet) to each group and

give them their container of water.

2. Once each group has their objects, pass out the water

containers and have them test whether the objects sink or

float and remind them to record it on their sheets, writing

the name of the object they’re testing in the 1sts column,

whether they think it will sink or float in the 2nd column,

and then their 2 trials in the 3rd and 4th columns.

3. After everyone has tried their objects twice, pass out the t-

chart sheets and tell them that they’re going to use their

first sheets to complete this sheet.

Independent Practice:

Have students complete the t-chart, writing on either side of

the t-chart the names of the objects that sank or floated.

Closure:

Have children get to where they can see the big container

and show them the two cans of soda. Put them in the water

(the diet colored soda will float but the colored soda will sink)

Tell them why (because the colored soda is heavier due to

sugar, the diet colored soda has no sugar, but instead has

artificial sweetener which is lighter).

Evaluation:

Students will complete a t-chart (see sheet) using their data

collection to write which items sank and which floated. They

will also turn in their data/prediction sheets for participation

credit. They will write a journal entry about why things sank

or floated based on what they saw during the experiment.
