6. Identification of: Parenchyma, Collenchyma and Sclerenchyma tissues in plants, striped, smooth and cardiac muscle fibers and nerve cells in animals from prepared slides. Drawing of their labeled diagrams.

7. Determination of the melting point of : Ice and the boiling point of water.

8. Verification of the Laws of reflection of sound.

9. Determination of the density of :Solid (denser than water) by using a spring balance and a measuring cylinder.

10. Establishing the relation between the loss in weight of a solid when fully immersed in :
