4 Labs

         Last week we did 4 labs the first was the candle the next was the marshmallow the next was the big candle and last was the matter lab. First i will talk about the small candle lab. Frst in the small candle we saw the physical properties some that I saw were that the candle was rough and it was small. After we lit the candle we saw the chemical changes one chemical change I found was that the candle was melting and burning.

Next we did the marshmallow lab. First we saw the physical properties one was that the small marshmallow was small. Then we ate the marshmallow and the marshmallow tasted sweet. Then we saw the physical properties of the big marshmallow were similar to the ones of the little marshmallow. After that we lit the Bunsen burner to burn the marshmallow and see a chemical change. After that we ate the burned marshmallow.
The third lab we did was the big candle. We had to observe the candle and find its physical properties one property was smooth. We lit the candle and then saw a chemical change. After that we mixed vinegar with water. Then we put the glass over the big candle. Then the flame went out because the flame ran out of oxygen.

The last lab we did was the sugar lab. Then we saw the sugar’s physical properties we saw that the sugar was cubed, sweet, and small. Then we crushed the cubes making another physical change. then we mixed it with sugar. After that we burned the last 2 pieces of sugar. First we saw that the sugar turned yellow the black. In the end we saw that the sugar was rough and fragile.
