Changes in Matter Graph

What is Matter?

• Matter is anything that has mass and takes up space. This includes solids, liquids, and gases.

The Law of Conservation of Matter

• Matter cannot be created or destroyed; it can only change forms.

When Matter Changes Form

• Whether something is melting, dissolving, or evaporating, the total amount of matter remains the same.

• Example: Melting ice – Ice changes to water, but the amount of matter stays the same.

How Do We Use Graphs to Show Matter?

• Graphs can be used to show the weight of matter before and after it changes form.

• Example: A graph showing the weight of an apple before it is cut, and the pieces afterward.

Tracking Matter in a Recipe

• When you mix ingredients to bake a cake, the total weight of the cake is the same as the ingredients you started with, even though they look different.

Does Matter Disappear?

• When you dissolve sugar in water, it may seem like the sugar disappears, but it’s still there!

• The mass of the water and sugar combined doesn’t change!

Putting It All Together!

• Conservation of matter means that matter is always conserved, even when it changes form. Graphs help us visually track these changes.
