Week 6 Day 1
Useful and Harmful Materials
I. Learning Objectives: Investigate changes that happen in materials under
the following conditions:
2.2 Application of or exposure to heat
II. Subject Matter:
A. Concepts: Heating materials can cause materials to change
Example:
A slab of butter left lying in the sun will melt.
When ice is warmed it changes into water.
When you heat water, tiny droplets of water leave the container and enter the
air. These tiny droplets are called water vapor. This process is called
evaporation and is part of the water cycle.

D. Process Skills: Observing, , Identifying, Describing
E. Value Integration: Carefulness in handling hot objects
III. Learning Tasks:
A. Engagement:
Show picture of an ice cream stick.
Ask: What state of matter is it? When expose to heat what do you
think will happen?
B. Exploration:
Activity 1: Video Presentation:

hold the tin can with butter or margarine) over the flame.
b. Heat the tin can for 2-3 minutes
c. Observe and record what happen to the butter
Questions:
1. What happen to each material when heated? Why?
2. Is there a change in the appearance of the material?
3. What change took place?
4. Describe the changes in the properties of the materials
that took place when heated.
C.Explanation:
1. How do you feel with the activity?
2. What happen to the chocolates when heated?
3. What happen to the butter when heated?
4. What happen to the crayon when heated?
5. What do you call the changes that took place in the materials
Whenheated?
D. Elaborate:
Motherwants to make sweet banana cue for a snack, what do you think will she do with
the sugar for it to stick to bananas?Why?
E. Evaluation:
True or False
1. Size and shapes of pieces ofwood changes when heated. -False
2. Water cools when placed under the sun.-False
3. Evaporation occur when water is heated.-True
4. Marshmallow melts as you exposed it to sunlight.True
