Miah started a fire in her backyard. She began with fresh cut fire wood and the end result was black ash. Below are her observations:
Firewood is brown, hard, flammable, and has a pine scent.
Ash is black, soft, leaves a residue, and has a smoky scent.
What evidence do you have that a chemical reaction occurred? (Select ALL that apply)
The end product of ash doesn't look like the wood that you began with.
The wood was burned which began a chemical change. The atoms in the wood rearranged to form ash and a few other by-products.
You can form the ash back into wood, you just have to have lots of pressure.
The ashes from the fire smell quite different than fresh cut firewood you began with.
Check all of the following example that are "real world" examples of physical and chemical changes AND are identified correctly.
Melting Point: An ice cube melting in a glass is a physical change.
Reactivity: Hydrogen peroxide and potassium iodide combine to form creating "Elephant Toothpaste" which is a chemical change.
Solubility: Solving the equation 3 + x = 15 is a physical change.
Decomposition: An apple beginning to turn brown is a physical change.
Explain one connection you can make between a chemical or physical change you have seen or experienced in your world:
