                                                2. heat shield - supporting equipment in a laboratory because beakers or                                                     any type of  glassware cannot be heated directly with a flame from the Bunsen burner
3. bottle - to keep some chemical inside it.
                        4. flask - used in a laboratory to hold reagents or samples.
                                                 5. Beakers - hold and measure the liquids.
                                                6. test tube - set by chemists to handle chemicals,especially for                                                                     qualitative  experiments and assays                                                                                                         7.

                                                8. watch glass - to hold solids while being weighed, for heating a small                                                       amount of substance and as a cover for a beaker.
                                                 9. stirring rod - stirring the liquid.
                                                10. owire - To grab a small piece of some chemical.
                                                11. pipette - used in chemistry, biology and medicine to transport a                                                                 measured volume of liquid.
                                                12. scoopula - a tool with a deep bowl shaped end that is used to dig out                                                             and move a soft substance or powder.      
                                                13. clamp - it is used to hold rounded laboratory glassware,for example,a                                                       beaker,flask,etc.
                                   14. evaporating dish - liquids are heated over a flame so that they evaporate,leaving a solid residue.

my feeling

I felt very fun very fun sometimes when I learn math with teacher Gary.I think when teacher Gary teach I can see the calculation in my head and we can understand it if we listen to the teacher. In Add math class It's a little bit boring because I didn't  like math very much but when I study here I felt better with math.
