Quiz: scientific report

Experiment 1: A student wants to investigate the effect of different types of fertilizer on plant growth. What are the independent and dependent variables in this experiment?

Answer explanation

The independent variable is the type of fertilizer, and the dependent variable is plant growth.

Experiment 1: What are the controlled variables in this experiment?

Answer explanation

The controlled variables in an experiment are the factors that are kept constant and unchanged throughout the experiment to ensure that any observed effects are due to the manipulated independent variable.

Experiment 1: What would be a suitable title for experiment 1?

Answer explanation

The suitable title for Experiment 1 should reflect the purpose or focus of the experiment, such as 'Effect of Temperature on Enzyme Activity'.

Experiment 1: What is the aim of experiment 1?

Answer explanation

The aim of experiment 1 is to determine the specific outcome or result of the first experiment conducted.

Experiment 1: What is a possible hypothesis for experiment 1?

Answer explanation

A possible hypothesis for experiment 1 could be that increasing the temperature will lead to a higher rate of enzyme activity.

Which of the following material lists correctly follows the instructions of writing material lists that students need to list the QUANTITY and TYPE of equipment?

• 1. Watering can, gardening gloves, shovel

• 2. 2 watering cans, 1 pair of gardening gloves, 1 shovel
