Cells Activities
Students look at binocular microscopes, gather things to look at, give them some examples of dead insects etc. experiment with drawing them........ Complete the following prac
 * Activity 1: Using a binocular microscope**
 * ACTIVITY 2: magnification**
 * Talk to students about how to calculate magnification and show them the parts of a microscope. You can also use core science 1 to help. There is a good diagram and description.
 * Activity 3: using monocular microscopes**

** Monocular Microscopes **
 * Aim: ** How to use a light microscope
 * Materials: **
 * Microscope
 * Newspaper
 * Scissors
 * Eye dropper
 * Slide
 * Cover slip


 * Method: **
 * 1) 1. Cut out a small ‘e’ from your newspaper.
 * 2) 2. Place it on the centre of your slide.
 * 3) 3. Put a large drop of water on the ‘e’ using the eye dropper.
 * 4) 4. Carefully lower the cover slip onto the slide to cover the ‘e’. Make sure there are no air bubbles under the cover slip.
 * 5) 5. Secure your slide to the stage of your microscope and observe, at low power.
 * 6) 6. Answer the following questions.
 * Discussion: **
 * 1) 1. In which direction did the e move under the microscope when you moved the slide a) towards you? B) to the left?.
 * 2) 2. Draw your field of view, and estimate the area covered by the ‘e’ at this magnification.
 * 3) 3. Change to a higher magnification and repeat question 2.


 * Homework activity: ** microscope sheet, label the parts of a microscope and state what each part is for.

Brief discussion about cells.
 * Activity 4 :** Introduction to cells
 * Smallest living thing.
 * Make up living things
 * Group together to form tissues
 * Too small to be seen with the naked eye etc


 * Activity 5:** pond water prac
 * Prepare a slide of pond water and see how many different things you can see in it.
 * (aim to get students thinking about the different kinds of cells/ single celled organisms etc.)
