MSCERT-Science-Grade 7

[edit]

[Contributor - Anu Nived]

Objective: To teach the students about elements, compounds and mixtures and how they differ

Subtopics to be covered:

  1. Matter
  2. Metals / non metals / Metalloids
  3. Molecular Formula
  4. Methods of separation

Learning Outcome:

  1. Students know about elements, compounds and mixtures that we use in our daily life
  2. They know about the various separating methods to separate mixtures
  3. They can write the molecular formula of various compounds

[Contributor - Kripa S]


1. In your village, visit a place that has a fence of wire. Take few small marbles or pebbles along with you. Throw them all in one go into the fence. You will observe that few of the pebbles will pass through the fence to the other side, and few will get hit and bounce back. This is how the electrons also move.
