SCIENCE 5
4.0. B. Conservation of Matter
Objectives
-Students will cite evidence to support
the statement, “No matter how many
parts of an object is assembled, the
sum of the whole object made is
always the same as the sum of the
parts.”, in order to describe how
matter can change from one form to
another without the loss of mass.
ENGAGEMENT
EXPLORATION
Station 1: Fun with Lego!
Procedure
1.Give 10 pieces of Lego to each student.
2.Find the mass of Lego individually.
3.Find the sum for the total mass of all the
Lego.
4.Have students construct an object then,
find the mass of the whole object.
5.Compare and contrast the mass of each
object with the mass of the Lego taken in
step 3.
Station 2: Clay-Creation
Procedure
1.The group will be given 1 block of clay.
2.Take the mass of the whole block of
clay.
3.Divide the block of clay to each student
in the group.
4.Find the mass of each piece.
5.Have students create a figure from the
clay.
6.Get the mass of the each object then,
compare and contrast with the mass of
the clay in step 2 and 4.
Station 3: Pizza Dough
Procedure
1.Students will be given a dough recipe.
Example: 1 cup flour and 1 cup water
1.Measure the mass of each ingredient.
2.Solve for the total mass of all the
ingredients.
3.Make dough with the recipe.
4.Compare and contrast the mass of the
dough with the mass of the ingredients in
step 2 and 3.
EXPLANATION
-Go over the questions
-Clear-up any misconception.
-Explain the relationship between the
masses of whole objects to the sum
of the mass of their parts.
ELABORATION
Group Activity
-The group has to come up with a
real world example of their
understanding of conservation of
matter(make a poster, make a list,
use objects in the classroom etc.).
