An investigation involves determining which metal is better for making pots that will cook food faster. Which is the best hypothesis to use for this investigation? Copper is better than iron for making pots. Copper is more malleable and heats up faster than iron. If copper is a better conductor, it will heat up faster than iron. If copper heats up faster than iron, it is better for making pots.

    A scientist would most likely need to update her model when it has become too simple. no longer supports the latest results. reduces the need for verbal explanation of data. no longer appears interesting.

    ok A scientist wants to use a model to help present the results of his detailed scientific investigation. Why would a model be useful? because the model makes the concepts easier to understand because the model is easy to put together and to use because the model prevents other scientists from asking questions because the model requires the audience to pay full attention to it
