SCAVENGER HUNT

ELEMENT #1

• Titanium
• This golf club is made of titanium.
• Ti

ELEMENT #2

• Compressed nitrogen (found in a fire extinguisher)
• N

COMPOUND #1

• Crystal chandelier
• Made up of silicon and oxygen elements chemically combined (SiO2)
• (There are many types of crystal)

COMPOUND #2

• This soil has methane in it.
• Methane is a compound (CH4)
• It is made up of carbon and hydrogen.

HOMOGENOUS MIXTURE #1

• This perfume looks the same throughout.
• Just like HOMOZYGOUS DNA has two of the same traits given
• (Such as gg or GG)

HOMOGENOUS MIXTURE #2

• The second mixture we found was air freshener
• Beautiful garden scented!! :)
• Same thing- it looks the same throughout, and resembles
• the Homozygous DNA that is passed down through generations

HETEROGENOUS MIXTURE #1

• We chose a homemade soy sauce with spices and oil, etc.
• Each ingredient is separate and has the same identity
• (If you remove it from the mixture)
• This resembles heterozygous DNA (Gg)

HETEROGENOUS MIXTURE #2

• This bowl of fruit salad is delicious and nutritious.
• It is also a heterogeneous mixture, and the fruits can be taken out of the bowl
• (Without changing their identity)

PHASE CHANGE

• This melting ooblek is a phase change
• It is this because it changed from a solid to a liquid while it melted
• And the identity of the ooblek stayed the same.
• This is the same as if it turned from a liquid to a solid
• The ooblek didn't change; it's particles just got closer or farther apart from each other

PHYSICAL CHANGE

• When I first put the soap on my hands, it was clear.
• You can kinda see it in this picture
• BTW's this soap is vanilla cookie scented.
• Just wanted to give you the heads up.

PHYSICAL CHANGE

• When I rubbed my hands together, the soap turned white.
• This is a physical change.

CHEMICAL CHANGE #1

• As you can see, the potstickers were seared
• Some turned brown because of the heat
• The texture also changed
• The identity was changed in the potstickers
• Yummy potstickers :)

CHEMICAL CHANGE #2

• Ms. Crosby set the money on fire.
• This shows flammability since a dollar bill is made of mostly paper
• But she put alcohol on it first so it didn't burn.
• If we pretended she didn't, then the money would change.
• It's chemical identity would change and it would be a different substance.

THANK YOU FOR WATCHING!
