I really need your help to determine if the following techniques are possible when analyzing scientific data (biodiversity in water) with pupils.

I think an English science teacher can help me determine the techniques.

Approach
1) Task organization and information distribution
The various tasks will be divided into as many parts as the members of the groups of students involved
Investigation
2) Investigation activities will be based on three components: investigation (analyzing problems from different points of view), interaction (activities and skills) and interpretation (presentation of findings in front of the partner students)
Cooperative Learning
3) Students will work in heterogeneous groups to achieve a common task.
Problem solving
4) Students will be asked to find creative solutions to solve problems and therefore achieve their results. This method includes the following activities:
Understanding the problem
Gathering information about the problem
Determining ways of solution
Preparing report and its evaluation
5) Experimental method
Investigation activities involve manipulating one variable to determine if changes in one variable cause changes in another variable

Assistance needed.
Also, be sure to read up on the scientific method -- the terminology and order in which investigation is carried out.
