Use for teaching students on reading the main and vernier scale of a vernier caliper. Features include zooming in and out of the vernier calipers to enlarge the reading, changing the vernier body translucent to help students read the main scales easier and hide or reveal answers to quickly assess students understanding.

Control the force meter to increase or decrease the forward force acting on the car. As the car accelerates, air resistance increases until net force reaches zero. Teachers can use this to illustrate constant speed, increasing speed, decreasing acceleration, net force and speed-time graph of a moving object.

Use to illustrate the rays through a thin converging lens and the formation of image. Move the object from distance of greater than 2F to less than F and observe the image formed.

Use to illustrate to students the refraction of light through a rectangular block of material. <br /> Features include ability to rotate the ray box and move it along the top or side of the block, observe refraction of light and total internal refraction a various angles, and ability to select the material such as glass, water, plastic and diamond. Observe the changes in refraction for different materials.

<p>Menstrual cycle activity based on Cambridge International O level Combined Science Syllabus 5129. Students use the flash file and activity worksheet to learn about the menstrual cycle such as length of the cycle, fertile period and ovulation.</p>

<p>Based on Cambridge International Combined Science O Level code 5129. Contents in the file is used as an end of lesson activity, for teacher to assess the teaching and learning on basic functions and parts of a flower, seed and human reproductive system. Using a mouse and projector, teacher can ask students to come forward and click and drag to label the diagram.</p>

<p>Based on Cambridge International O Level Physics, code 5054.<br /> Can be used as part of lesson or as lesson summary after class activity. Teacher can drag and drop paper, Al or Pb into provided slots and observe the change on count rate. Can be use to discuss random activity and penetrative power. Also included is 4 unknown sources which students can use to identify the radiation emitted by using the setup. Teacher can start class discussion based on observation on the drop in countrate to identify the unknown radiations emitted by a source.</p>

<p>Flash file for drag and drop and fill in the blanks for functions of the different parts of the human digestive system. Include parts of the mouth, oesophagus, stomach, liver, pnacreas, gall bladder, small and large intestine. Can be used as class activity for lesson recall or summary.<br /> Syllabus based on Cambridge International O Level Combined Science Biology component, syllabus code 5129</p>

<p>Electromagnetic Induction flash file based on Cambridge O Level Physics 5054 Syllabus.</p>

<p>Simple flash animation on using the cloud chamber to observe tracks produced by alpha, beta and gamma radiation.</p>
