Stations Lab

Station 1- Beans

• Mixture (not chemically combined, just physically)

• Heterogeneous Mixture– Large particles

Station 2- Salt Water

• Mixture (not chemically combined, just physically)

• Homogeneous Mixture- – Particles are VERY small– Does not scatter light

• made of 2 pure substances- what are they?– Water and salt– Compounds

Station 3- Tin

• Pure Substance• Element– #50 on periodic table

Station 4- Baking Soda

• NaCO3• Three elements- – Na, C, O

• Pure Substance– Chemically combined

• Compound

Station 5- granite

• Mixture (not chemically combined, just physically)

• Heterogeneous Mixture– LARGE particles

Station 6- Water

• H2O• Two elements chemically bonded• Pure Substance• Compound

Station 7- Muddy Water

• Mixture (not chemically combined, just physically)

• Heterogeneous- because shows Tyndall Effect

• Suspension because particles are big enough to settle out
