5th Grade IA3 Review

A geographic information system (GIS) helps scientists visualize, analyze, and interpret data about locations on Earth. Which statement describes how GIS mapping can help in planning for floods?

• They can help identify weak infrastructure, like roads and bridges, that would need repair before a flood.

  
  

• They can help seismologists understand how floodwater can absorb into the ground and cause plates to shift.

  
  

• They can help meteorologists understand the air temperatures and cloud formations before and after a flood.

  
  

• They can help search for lost pets that were separated from their families during floods and other severe weather.

Liana puts a stick of butter in a pan on the stove. She turns the stove on and watches the butter melt. However, the heat on the stove is too high, so the edges of the melted butter scorches and burns. Which statements describe the changes Liana observed in the butter?

• Both the melting and the burning of the butter were chemical changes.

  
  

• Both the melting and the burning of the butter were physical changes.

  
  

• The melting butter was a physical change while the burning butter was a chemical change.

  
  

• The melting butter was a chemical change while the burning butter was a physical change.

• The paper can be burned easily when unfolded.

  
  

• The paper can be unfolded and will remain the same size.

  
  

• The paper can be stained with paper or dye after folding.

  
  

Mark is chopping up a tree into small pieces. He feels that he is causing a physical change. Why is he correct?

• The tree is a different type of species now.

  
  

• The chemical identity of the tree has not been changed.

  
  

• The tree lost cells when it was cut up.

  
  

• The tree has a new chemical identity.

Matter can change: the changes can be physical or chemical. When a physical change happens, nothing new is formed. During a physical change, matter changes form; it can be crushed or torn. It can also change state; it can change from a solid to a liquid as it melts. When a chemical change occurs, something new is formed. The reactant or reactants change and become something new. For example, a piece of iron can rust. The rust is the new substance that is formed. It is called iron oxide. Also, when something burns, it is always caused by a chemical change.

Review the images below. Which image shows a physical change?
