  1. 4.0. B. Conservation of Matter SCIENCE 5

  2. 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.

  3. ENGAGEMENT

  4. EXPLORATION • Station 1: Fun with Lego! • Procedure • Give 10 pieces of Lego to each student. • Find the mass of Lego individually. • Find the sum for the total mass of all the Lego. • Have students construct an object then, find the mass of the whole object. • Compare and contrast the mass of each object with the mass of the Lego taken in step 3.

  5. Station 2: Clay-Creation • Procedure • The group will be given 1 block of clay. • Take the mass of the whole block of clay. • Divide the block of clay to each student in the group. • Find the mass of each piece. • Have students create a figure from the clay. • Get the mass of the each object then, compare and contrast with the mass of the clay in step 2 and 4.

  6. Station 3: Pizza Dough • Procedure • Students will be given a dough recipe. • Example: 1 cup flour and 1 cup water • Measure the mass of each ingredient. • Solve for the total mass of all the ingredients. • Make dough with the recipe. • Compare and contrast the mass of the dough with the mass of the ingredients in step 2 and 3.

  7. 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.

  8. 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.).

  9. EVALUATION
