Discussion Overview

The discussion revolves around finding suitable experiments for constructing an investigation design report. Participants explore various experimental ideas that could be simple enough to guide the report's construction while considering the complexity and relevance to personal interests.

Discussion Character

  • Exploratory, Homework-related

Main Points Raised

  • One participant suggests building a catapult using arrows and bungee cords, proposing calculations related to velocity, kinetic energy, angular velocity, and momentum, while expressing uncertainty about the complexity of the idea.
  • Another participant expresses that the catapult idea may be too complex for their needs and requests alternative suggestions.
  • A different participant advises choosing a subject of personal interest and suggests conducting an experiment comparing the heating rates of water in pots of different dimensions, emphasizing the importance of consistent conditions.

Areas of Agreement / Disagreement

Participants do not reach a consensus on a specific experiment, and multiple suggestions are presented, indicating a variety of approaches and preferences.

Contextual Notes

Participants express varying levels of complexity in their suggested experiments, and the discussion reflects differing interests and potential challenges in selecting an appropriate investigation design.

can anyone help me find a simple experiment that i would be able to use to guide me to construct an investigation design report?

You could build a catapult out of arrows and bungee cords. Set the stopping point at some angle. Then calculate expected velocity, kinetetic energy, etc... Maybe the angular velocity, momentum etc... of the swining arm...possibly coefficient of friction, stuff like that.

I don't know if this is too simple or advanced...


Fun nevertheless.
 
cheers for the suggestion, i think it may be alittle complex for what I am trying to do. have you got any others??
 
Welcome to PF, Jstark11. It would probably be to your advantage to choose a subject that you enjoy and pick an experiment that is within that area. What are your interests?
 
How about you take two pots, one wider than the other, and fill them with the same amount of water (making sure the water's all at the same temp.) Put a pot on a burner and heat it up until it boils; every minute or so record the temperature with an oven thermometer or something. Do the same with the other pot some time later in the day (after the burner's cooled down). See if the dimensions of the pots have anything to do with how quickly the water heats up.
