With the phenomenon of climate change, a new mixture has rained down and flooded the area, including the town. It is a non-Newtonian fluid which has properties of both liquids and solids. The challenge for the second graders was to build structures that will stay up and not sink into the mixture. Along with that, walkways and bridges had to be built so that people can move around their town. The structures had to withstand rains that could leak into the structures. Additionally, the structures had to be able to withstand this mysterious fluid dropping from the sky.  The second grade engineers had their hands full with this new material that could take over all areas of the world!

Matter is anything that takes up space and has mass; everything around us is made of matter. The way the matter's molecules are placed determine what kind of matter it is.

States of Matter States of matter are the different forms of matter; there are three that we will focus on: solid, liquid and gas.

Solids have a definite shape; their size and shape remain the same and their molecules cannot move.

Liquids don't have a definite shape; they take the shape of their container and their molecules can move around.

Gases do not have a definite shape and their molecules are free and move around very fast.

Properites are the characteristics of something that help identify it. It's what something is like or What it can do.

Non Newtonian Fluid Non-Newtonian Fluids are a type of fluid that flows differently depending on how much pressure is applied.

Prototype A prototype is an early sample or model that is built to test an idea or a process.
