You have explored some interesting, informative, and amusing examples of models. Now it's time to get creative and make your own model. Here is the requirement checklist for your model: ✔ Model types can include drawings, diagrams, physical models, virtual simulations, or videos. ✔ Models must be created by you, not something selected from an online or outside source. ✔ Submit a presentation, picture, video, or screenshot of your model. ✔ Submit a one-paragraph summary describing the topic you chose, your model, what it represents, how you made it, and the specific science involved. It is important that you are using science terminology and are accurate. Now that you know how to create and submit your model, you will need to choose a topic for your model. Choose one of the three topics listed below. Select each topic for an overview. Conservation of Mass Atomic Theory Thermal Energy Explore the effects of thermal energy. Model how adding or removing thermal energy affects motion in particles in a pure substance, such as water, or in a chemical reaction. The image shows the motion of particles changing due to thermal energy. Slow moving particules plus themeral energy equals fast moving partcules.

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
