What happens to
objects when you put them into water?
Students should predict which objects will sink or float
before they test them in the water. Allow students to test objects in the water
to see if they were correct. Have students record their results on the activity
sheet for Learning Experience 7 in the Properties Student Activity Book. (Please see
PDF) Have the students draw objects on top or bottom of
the water to show which objects sank or floated.After students are done drawing
their objects, have them work on the next page of the activity sheet for
Learning Experience #7 in the Properties Student Activity Book. (Please see
PDF) Students will circle the objects that floated in
red and circle the objects that did not float in blue.
