Our experiment on changes in materials!

Today we are going to discuss about changes in materials. To make it simple me and my group had an experiment about changes in materials.... We are going to discuss about physical and chemical change. First off we will start with the materials needed.

Activity no.1                                                          Activity no.2                            

Materials needed:                                             Materials needed:
◦ spoon                                                                ◦ spoon
◦ candle wax                                                        ◦ beaker
◦ sugar                                                                ◦ water
◦ butter                                                               ◦ baking soda
◦ candle                                                              ◦ vinegar
                                                                           ◦ flour    

                                                                                                                                                                                                                                                     

Activity no.1
1. First we place some sugar in the spoon.
2. Light the candle. Heat the the sugar in the spoon over the candle flame until all the sugar has melt
3. Remove the candle flame. Leave the sugar in the spoon to cool.
4. Repeat steps 1 to 3, replacing sugar with butter
5. Repeat steps 1 to 3, replacing butter with candle wax
(**Note: We recored every step in this activity)

Activity no.2

1. Add a spoon of flour into the beaker of water. Observe what happens.

2. Add a teaspoon of baking soda into the beaker half-filled with vinegar. Observe what happens.

This is me and my group

With this experiment i was able to conclude that:

◦ No new material is formed when a physical change takes place. A new material is formed when a chemical change  takes place.

◦ Physical changes are usually reversible. Chemical changes are usually non-reversible.
