2. Who am I ??
I’m something that covers your eyes
But I do not block out light
Instead you look through my lenses
As I help protect your eyesight.
I’m found on scientists' faces
As I’m something that they wear
I help protect eyesight
And always come as a pair
3. Why do we wear safety goggles?
Goggles, or safety glasses, are forms of protective eyewear that usually enclose or
protect the area surrounding the eye in order to prevent particulates, water or
chemicals from striking the eyes..
6. What is Thremometer?
A thermometer is the instrument used to tell the air temperature.
A thermometer is usually made up of a small, hollow glass tube. At the bottom of
the tube is a bulb, which holds a liquid such as alcohol or mercury.
When there is an increase in heat, the liquid inside the bulb expands, pushing up
into the tube.
7. Activity: Try to read the temperature of
the water using the thermometer.
8. Stopwatch
A watch with a hand or a digital display that can be started and stopped at will for
exact timing (as of a race).
