a line graph
I don't know what visual model is, but 1/2 + 3/16 = 11/16 .
A line graph would show this.
A line graph is used to display data or information that changes continuously over time. Line graphs show overall trends such as an increase or decrease in data over time. In this case, it would show a change in air temp over a long period of time.

Graph
A series of before-and-after photographs showing the actual melting of polar ice caps over time would be a powerful visual aid for a speech on this topic. This can help demonstrate the impact of climate change on the environment and reinforce the urgency of the issue to the audience.
A visual aid of data is giving an example or showing your data in picture or visual form. "I'm going to take over the world!" So you would have a picture of the Earth or showing us how your going to do it.
Scientist
if it did know what it was doing then no but if it did not know better then yes.
months* I think the best choice would be a line graph since line graphs are known to display data that changes over time. In your question the mass probably changes throughout an owl's life. This info would show clearly in a line graph since the mass changes.
it just goes down because of weathering
Fossil evidence would indicate change over time.
Data gathering
you would expect that the populations of animals are increasing or decreasing or because of no rainfall the plants will get dried.
The mixing of different people caused changes. English is a combination of a lot of different languages put together over time.
