Get a large tin can that may have contained stewed friut or dogfood etc . Put some nail holes in the side of it in a column starting from the bottom and going near to the top.Get another container and continuosly pour water into the tin can. The flow of water from the bottom hole spurts out the most because the pressure at the bottom of the can is larger than at the top . This demonstrates the principle that pressure is equal to height
times density.
Very cheap.
Quick to manufacture.

Optics is the best
requirements : A prism with its refractive index known, a laser ligt(red) or any u can choose,few pins,protactor,pencil,ruler,A4 size Paper.
aim: to find the diff velocities of colour light when it passes through a medium, and its angle.
how to do it:1.trace the figure of the prisms on the paper (say Triangle ABC ( BC as base)
2.draw a 90 degree line from side AB.
3.place your prims on the strucure of prism u hve traced put ur laser light on the line u hve drawn and switch it on
4 u will see that the light bends when it comes out frm the other side place the pins on the light which comes out frm the other side.
5 draw the line of the light comin out and measure the angle.u will see the deviation
6 u can do it with diff angles like 15,30,45,60,75 anything
and for speed formulae. velocity = (3 x 10^8)/r.i of the prism
I did it in my grade and got A

Internet radio is great. If you have internet access at work you should be able to access it. And the choices are enormous. Sometimes getting up and taking a brief walk helps. So does simple stretching. Taking deep breaths can help as well. I'm sorry you're having a rough patch at the moment. Moods can really sabotage us if we don't know how to handle them. I'm assuming that you don't experience frequent sad moods, because if you are often sad, maybe you should see a doctor. But it sounds as if you're reacting to real-life stressors. Remember HALT - never let yourself get too hungry, angry, lonely or tired. That'll help you mantain calmness better. And remember that the bad stuff passes.

take a transparent jar,a big rubber balloon on or piece of stretchable rubber sheet,a string, few chick-peas or black gram or dry green peas.
Preparation- put the seeds in the jar.sew the string to the centre of the rubber sheet and put some tape to keep it tied.stretch and tie the rubber sheet on the mouth of the jar.your model is ready.now run your fingers up and down the string by first tugging at it slowly and then rapidly.

Physics is a very large field, covering Sound to Light and Matter to Relativity to Forces and Motions to Magnetism to Electricity, and that's just Units 3 and 4 in Victoria. Please state what area of physics, though I would assume given that this is year 9 it would be something to do with forces (F = ma).

A good and important model is to show what equilibrium is. A good model is to build a balance scale. It also mimics a mathematics equation.

you can make
1) kalidoscope with three pieces of slides and a big cover slip from your biology box.
2) pin hole camera using box of any syrup and semi-transparent paper.
If you select my idea and if you have any problem to do that you may contact me at- amitabhashes@sify.com.
