Replication
Some sources of error in a principle of moments experiment include friction in the pivot point, inaccurate measurements of distances or forces, misalignment of the apparatus, and neglecting the weight of the beam. These errors can lead to discrepancies between the theoretical calculations and experimental results.

The edible pea experiment to formulate his basic principle of heredity
You have to calculate the amount of error that can be expected in your experiment, and if the results exceed the experimental error, they can be considered to be meaningful. We would really have to discuss a specific experiment to see how this principle works.
The principle of interspersion involves distributing treatments evenly throughout the experimental area to reduce the impact of local variation on the results. It should be incorporated into the experimental design by randomizing the placement of treatments to ensure that any potential sources of variability are evenly spread across the experimental units, leading to more reliable and robust results.
Anything that has to do with physics on the planet Earth
Griffith' experiment in Biology refers to an experiment that tries discover the "transforming principle" in pneumococcus creatures.
The Bifilar Suspension experiment involves suspending a rotating object with two threads (bifilar) to measure its moment of inertia. The theory behind the experiment is based on the principle of conservation of angular momentum, where the angular acceleration of the rotating object is related to the applied torque and moment of inertia of the system. By analyzing the motion of the object under different conditions, one can determine the moment of inertia of the object.
The blobs in a bottle science experiment demonstrates the principle of density. When two liquids with different densities, such as oil and water, are mixed together in a bottle, they form separate blobs due to their immiscibility. The blobs created in this experiment help to visualize how substances with different densities do not mix together and instead form distinct layers.
When objects of different mass are dropped under the same gravitational conditions, they will fall at the same rate and hit the ground simultaneously. This is due to the principle of gravitational acceleration, which states that all objects, regardless of their mass, will accelerate towards the Earth at the same rate (9.8 m/s^2). This phenomenon was famously demonstrated by Galileo with his experiment at the Leaning Tower of Pisa.
The principle involved in a sonometer experiment is the resonance of a vibrating string with a known tension and length. By adjusting the tension and length of the string, the frequency of the sound produced can be measured. This can be used to determine various properties of the string such as its fundamental frequency, harmonics, and speed of sound in the material.
A proof of principle experiment is one designed to see if the idea is workable. Usually little if any data is collected. Example: " I wonder what happens if I push this button?" Better example: " Can energy be generated by wind?" To do a proof of principle experiment, it would only be necessary to generate "some" energy from "some" wind by "some" method. It would not be necessary to collect data or decide the practicality of a particular method.
