Let’s Do an Experiment!

In which subject do you often do experiments?

[k?'rekt]

[k?n'klu??(?)n]

[sa??n't?f?k]

['meθ?d]

using scientific methods. Doing

experiment is a scientific method.

1. Where does Danny think they should do the experiment?

2. What keeps the water in the jar?

3. Is Jenny sure of her theory? How do you know?

4. What does Danny conclude?

1. Danny thinks that they should do the experiment outside.

2. The force of the air./The air pressure.

Danny’s head and he won’t get wet.

4. Air is stronger than he thought.
