Review for IV term test 

Forces. Newton (N). Different types of forces. Gravitation. Weight. What is weight and how to calculate it. 

Mechanical work. Joule(J). Work vs energy.

Power. Watt (W)

Levers. Moments. Fulcrum

Electricity.Electric current. Voltage. Measuring current and voltage.  Ammeter, voltmeter. Series and parallel circuit.

Simple electromagnet.

Pulleys. Trading force for distance.  

HOMEWORK

- Over the break build a demonstration experiment showing the working principles pulley systems. prepare a model of a pulley system of your choice. 

Prepare also a poster, where you explain how pulley system works, how can we win in the force we have to use and what do we lose in. You should be able to bring examples where this particular pulley system can be used in (put pictures of these pulleys on the poster). 

Extra credit for creativity.

Review for III term test 

What kind of microbes are there in the world? 

What are the basic characteristics of viruses, bacteria and single celled eukayotic organisms? 

Bring one example of a virus, bacterium and single celled eukaryotic organism: describe it, describe the illness that it causes, are there cures or ways how to prevent the illness?
Turn your attention to vaccination, antibiotics and the natural way your body fights against microbes.

What is light? How does it travel through different substances? Describe experiments how to control that light travels in straight lines.

Dispersion and absorption of light. What are primary and secondary colours? How to create different colours using filters?

Describe how light reflects from different mirrors (plane, convex, concave). describe the law of reflection and draw a diagram to illustrate your explanation. Make sure you use all the terms.
Where can we use convex and concave mirrors? Bring examples. How does the image change in them?
Describe how light refracts in concave and convex lenses. Draw ray diagram. Construct diagrams showing how the image forms. Which is a diverging, which is a converging lens? Bring examples, where can we use diverging and converging lenses.

Anatomy of a human eye. Near- and farsightedness. What is wrong in the eye and how to fix it?

Very good explanations of how images form! Have a look.

Final activity of II term 

Find information about one harmful microorganism. Describe how that microorganism looks and where can we find it. Describe how a human can get an infection by that microorganism. Describe the illness/symptoms in two scenarios - when it is not treated, when it is treated. Find out, how widespread this disease/microorganism is and if there are areas where it is more common. 

Next week we will continue with this task.
