The students will watch a video of different types of reactions. They will do
this on Kidblog for homework. The teacher must post the video in a post for
the students to watch. The video is below.
Given the video on Kidblog the students will be able to identify the different
kind of reactions given a chemical equation with ninety percent accuracy.
Students should know that mixing different substances make new
substances. They should also know basic chemistry laws and concepts.
The video you must post is above in the section labeled “Video.” That is the
video you must post in a post on Kidblog so the students can watch it.
 Post the video in a post in Kidblog.
 The students will watch the video and take notes if they wish. They do
not have to if they choose not to although tell the students that it may
be helpful with the following exercises.
 The students will then go to another post the teacher has posted and
do the exercises telling which kind of reaction it is: synthesis
decomposition, single displacement, double displacement, or
combustion. The exercises are below in the section named
 The teacher should tell them how they did and make comments about
whether they should do the exercises over again watching the video
over again.
A. 2K + Br2 -> 2KBr – synthesis
B. Mg3N2 -> 3Mg + N2 –decomposition
C. CH4 + 2O2 -> CO2 + 2H2O - combustion
D. 4Al + 3O2 -> 2Al2O3 – synthesis
E. Zn +CuCl2 -> ZnCl2 + Cu – single displacement
F. 2KI -> 2K + I2 – decomposition
G. Fe2O3 + 6HCl -> 2FeCl3 + 3H2O – double displacement
H. H2 + Br2 -> 2HBr – synthesis
I. 2C8H18 + 25O2 -> 16CO2 +2H2O - combustion
J. Cl2 + 2NaBr -> 2NaCl + Br2 – single displacement
K. Fe + Cl2 - > FeCl2 – synthesis
L. 2NaCl -> 2Na + Cl2 – decomposition
M. 2C6H6 + 15O2 -> 16CO2 +18H2O - combustion
N. AgNO3 + HCl -> AgCl + HNO3 – double displacement
O. Mg + 2HCl -> MgCl2 + H2 – single displacement
P. 2N2O3 -> 2N2 + 3O2 - decomposition
You should grade them on well they understood the material. If they did not
do well have the repeat the exercise and watch the video over again. If they
did well on the exercise then tell them they did a good job.
Principles of Integrated Chemistry-Physics - CP.1
Students begin to conceptualize the general architecture of the
atom and the roles played by the main constituents of the atom
in determining the properties of materials. They investigate,
using such methods as laboratory work, the different properties
of matter. They investigate the concepts of relative motion, the
action/reaction principle, wave behavior, and the interaction of
matter and energy.
