Grade 8: Galileo
Project Title:
Observing the amount of Carbon Dioxide produced from the
decomposition of hydrogen peroxide
Research
Question:
How do varying amounts of manganese oxide affect the production of
carbon dioxide?
Hypothesis:
If varying amounts of manganese oxide are added to a solution of
hydrogen peroxide, then the production and the rate of reaction of
carbon dioxide will increase with higher concentrations of manganese
oxide.
Independent
Variable:
The amount of manganese oxide used
Dependent
Variable:
The amount of carbon dioxide produced
Constant
Variable:
The concentration of hydrogen peroxide used, the temperature at
which the reaction is conducted and the duration of the reaction

2.
Identify and Explain a research question for the scientific investigation.
A research question is an answerable inquiry into a specific concern or issue.
The question seeks to investigate the relationship between the amount of manganese oxide
added and the to a reaction mixture and the rate at which carbon dioxide is produced
during the decomposition of hydrogen peroxide. By varying the concentration of
manganese oxide, this experiment aims to determine if there is a correlation between the
catalyst concentration and the rate of the reaction.
Formulate a testable hypothesis for the scientific investigation.
3.
A testable hypothesis is a hypothesis that can be proved or disproved as a result of
testing, data collection, or experience.
Identify and Describe the independent variable.
4.
An independent variable is defined as the variable that is changed or controlled in a
scientific experiment. It represents the cause or reason for an outcome
.
Identify and Describe the dependent variable.
5.
A dependent variable is the variable being tested and measured in a scientific
experiment. The dependent variable is 'dependent' on the independent variable
.
Identify, Explain and Describe the constant variables.
6.
A variable whose value cannot be changed once it has been assigned a value.

7.
List of all apparatus and materials.
The difference between apparatus and materials is that an apparatus is an instrument that
has proper measurements whereas the materials are substances that are used in the
experiment. Majorly the apparatus is a non-consumable entity and materials are entities
that are consumed during an experiment.
