The Science of Flight

Investigation 1

What did we investigate?

We wanted to find out which would fall to the ground first, a square piece of paper or a ball of paper?

What predictions did we make?

Because both the pieces of paper were the same size before we rolled one up we thought they might fall hit the ground at the same time.

What did we do?

Science exp.1 003

What did we discover?

We found out that on every attempt the ball of paper hit the floor first.

Why was this?

We felt that the air was stopping the flat sheet from falling and slowed it down.

Further investigations?

What is Air?

How does it stop the flat page?

What is Air?

Air is an invisible gas made up of 78% nitrogen 21% oxygen and 1% of lots of different gases. Air is everywhere on Earth. The further up you go the less air there is.

 What is a gas?

A gas is a state of matter. In a gas the atoms aren’t tightly pressed together. Gases are all around the atmosphere. Vapor and gas mean the same thing but the word vapor is used to describe gases that are usually at room temperatures.

Investigation 2 What is Air

What is Air?

(States of matter)

What are we investigating?

  1. If Air is a gas what is a gas and what are the other states of matter?
  2. What is the difference between them?
  3. How can we demonstrate the three most common states of matter?
  4. How can we change the states of matter?

What did we do?

  1. We looked at the how the atoms are different in a liquid solid and gas.
  2. We looked at ice water and steam as an example of solid liquid and gas.
  3. We tried to turn change the state of the water from solid to liquid to gas and back to solid again.

What did we find out?

  1. The atoms is in a solid are closely packed together.
  2. The atoms in a liquid are not as close together and move freely
  • The atoms in a gas are really loose and fly about easily.
  1. If we heat ice (solid) it turns to water (liquid) and if we keep heating it turns to steam (gas) and if we then catch and condense the water and put it in the freezer we can turn it back to ic ice
