Year 10 Science Inquiry Skills (Wind Seed Dispersal)

What is the aim of an experiment?

• A guess about what will happen

• A clear statement of what the experiment is trying to achieve

• A list of materials needed

• A summary of the experiment’s findings

What is a hypothesis?

• A statement predicting the outcome of an experiment

• A summary of previous research

• A list of steps in the experiment

• An aim of the experiment

In an experiment investigating how the surface area of wings affects the time it takes for a seed to hit the ground, what is the independent variable?

• Wind speed

• Seed type

• Surface area of wings

• Time it takes to hit the ground

What is reliability in an experiment?

• How well the experiment answers the aim

• The ability to repeat the experiment with similar results

• The experiment's accuracy

• The length of the experiment

What does validity refer to in an experiment?

• The number of trials conducted

• Ensuring the experiment tests what it's supposed to test

• How fast the experiment can be completed

• The quality of the hypothesis

If an experiment does not answer the aim, is it valid?

• Yes, because it was conducted properly

• No, because it must address the aim to be valid

• Yes, if it was repeated several times

• No, if the hypothesis was incorrect

In the wind seed dispersal investigation we conducted last week... what is the dependent variable?

• The distance between Point A and Point B of the seed dropped

• the surface area of the wings

• Time taken for seed to hit the ground from Point A to Point B

• Weight of Wind Seeds

Why are both independent and dependent variable axes necessary on a graph?

• They make the graph look complete

• They help display how one variable affects another

• They are always placed on the same side of the graph

• They allow for random data placement

What is a trend in data on a graph?

• The title of the graph

• A noticeable pattern in the data points

• The scale used

• The color of the lines

How do I calculate surface area of my seed wings for the wind seed dispersal investigation?

• Length x Width (of each wing ) x 2

• Measure the whole cut out

• Measure the distance from where I drop it from

• Surface area is calculated by length x width x 3
