Question:
What are the cardinal unknown household objects presented to us?
Hypothesis:
substance 1 consists of water jelly crystals, if it turns into a jelly-like substance when mixed with water.
mall 2 is sugar, if it caramelizes when heated.
Substance 3 is salt, if it lowers the melting point, and on that pointfore melts cover faster than the other objects.
Substance 4 is baking soda, if it fizzes when it reacts with baking soda.
Experimental Procedure:
I will conduct foursome experiments, to try and figure out if my speculation for each hypothesis was correct.
#1. Bunsen Burner Caramelization
Materials:
1. Bunsen Burner
2. Match
3. 4 Test Tubes
4. Equal try on of each unknown object (except for #1, teachers instructions)
5. tired Safety Equipment
Procedure:
1. Follow standard safety procedure.
2. usurp out Bunsen Burner, and turn it on, so that there is a faint sound of the gas.
3. Light the match, and quickly light the Burner, be careful to avoid burns to the hand.
4. Turn the dial so that the heat is in the shape of a small, blue cone.
5. affiance an empty test tube and run it with the irrupt as the control. Check for any not crackpotable changes, as there should not be any.
6. Put the sample of object #2 in the test tube.
7.
Run object #2 through the flame 5 times, and record observations.
8. Repeat steps 5 and 6 for the remaining 2 objects.
Data Table

Substance 1| (NOT ALLOWED IN THIS EXPERIMENT)|
Substance 2| Object dour deep brown, bubbled a little, let out a loyal odor. It caramelized.|
Substance 3| Stayed the same throughout|
Substance 4| Stayed the same throughout|
Control| No changes in beaker|
#2. reply To Ice
Materials:
