Which life process is the monkey showing? Why is this important?
Movement. This is important for the monkey to move around, get food and also run away from predators.
A solution reacts with B solution and starts to bubble.
You test it for oxygen, hydrogen, and carbon dioxide. Explain the process for these tests.
oxygen = put a glowing splint inside, and it will re-light.
hydrogen = put a fire splint inside, and it will make a 'pop' sound.
carbon dioxide = put the bubbles in lime water, and it will turn milky.

Explain what the student needs and how to do this experiment.
The student needs a hard surface for sound to reflect.
They need a ruler to measure the distance and a timer to record the time.
They make a sound and record its echo.
Do the math: speed = 2d/t

A girl is mad at her crazy brother and yells very very LOUD!
She hears an echo by a nearby building that is 100 meters away.
The echo takes 0.625 sec.
What is its speed.
speed = distace / time
echo d = 2d so; s=2d/t
2(100m)/0.625 sec.
s=320 m/s
This is a eclipse that will happen in 2030. What would you expect to see in Taiwan and what would people in North West Australia see?
People in Taiwan will see a partial eclipse. But since it is on the outside, only a small amount of the sun will be blocked.
People in Australia will see more a total solar eclipse. Most if not all the sun will be blocked by the moon.
