Explore the wonders of chemistry in this fun filled presentation! Discover how to inflate a balloon
and make a rainbow of colors using chemical reactions! Students learn the difference between
physical and chemical changes and four hints that distinguish between the two types of changes.
Students will use observation skills to identify hints demonstrated in a series of experiments. They’ll
be amazed at how physical and chemical changes are a part of their everyday lives!

1. Identify the four hints used to describe physical and chemical changes (Physical changes do not change the matter, can be a
change in shape, can be undone or be a change in the state or phase of matter. Chemical change hints: heat, light, odor is
emitted, a color change occurs, a solid is formed, or gas is emitted through fizzing and bubbling).
2. Understand how the arrangement of molecules is fundamental in identifying chemical and physical changes.
3. Discover that physical and chemical changes occur all around us.
Helium is lighter
than the air around
us. That is why it is
commonly used in
balloons..
Dry ice is the
solid form of
carbon
dioxide
(CO2 ).
Hydrogen is
the most
abundant
element in the
universe.
1. Read about chemical and physical changes.

2. Have students determine which processes are physical or chemical changes.

3. Discuss examples of physical and chemical changes that happen in everyday life.
1. Understand chemical changes using an endothermic reaction.

2. Test whether household chemicals are acids or bases using an indicator made from red cabbage juice.
