This document provides an overview of a science lesson on floating and sinking. The lesson introduces the concepts of floating and sinking, identifies whether common materials like plastic, metal, wood, and rubber absorb or do not absorb water, and involves a class activity where students predict and observe whether selected objects will float or sink. The lesson also discusses how the density and shape of an object can impact whether it floats or sinks in water.

Science Ma’am Rose

3. Let us review
our past lesson

4. Identify the materials below if they absorb or
does not absorb water.

5. Eh di WOW!
CONGRATS….

6. Objective of the lesson:
At the end of the lesson, learners
can classify objects whether they
float or sink

7. Learning Circuit !
Sink means to go to
the bottom of water
float means to
stay on top.

8. Are
you
ready?

9. PLASTIC

10. METAL

11. WOOD

12. RUBBER

13. What are the words revealed from
the pictures?
PLASTIC METAL
WOOD RUBBER

14. Class Activity:
Each one will come in front, pick
one object then put it on the water
to find out whether it will float or
sink:

15. Analysis of the activity:
Question & answer:
Why do you think some objects
float while some objects sink into
the water?
Because of it’s density

16. Some things float on the surface of
water. Others submerged, partway
down,
Some things sink very fast and
some things sink very slowly.

17. The shape of an object can affect its
ability to float, but some materials float
no matter what is their shape - such as
styrofoam and wood.
Some things float at first, but then
slowly sink as they absorb water
through their holes

18. Evaluation:
List down on your paper 2 objects that
float and 2 objects that sink.
OBJECTS THAT FLOAT OBJECTS THAT SINK

19. Assignment:
Draw a picture of a river with
sinking and floating objects. Color
it.
