Lesson Plan version 1.1 acitivites

1. An organism such as horse has a number of organ systems. One such system is the circulatory system. Name an organ of the circula-tory system. Mention a tissue of this organ, and a cell of this tissue.

2. Take a peice of a layer from an onion. Remove a thin epidermal layer from this piece. Put this on a drop of water taken on a glass slide. Put a drop of iodine or any suitable staining solution on this piece. Observe the slide under a microscope with the guidance of your teacher. Under a microscope, you will see the cells

3. Experiment to demonstrate osmosis

Make a cup shaped cavity in a peeled potato . Pour sugar solution into the cavity. Place the potato in a container with little water. Mark the level of sugar solution. Leave it for about half an hour. Note the rise in the level of sugar solution.


4. Experiment to demonstrate diffusion

Take some water in a beaker. Drop a crystal of potassium permanganate into it. Observe the change in the colour of water-whether the change was gradual or immediate.

5.  Find out the differences between an organ and an organelle

 Collect information about the number of chromosomes present in some plants.
