Physics P5

For physics P5, you need to explain how different types of waves are used for communications. You need to explain what kinds of waves mobile phones, radio and television use to operate.
You also need to explain what optic fibres are, how they transmit information from place to place.

Physics P6 and 7

For Physics P6 and 7, we need to explain how electricity is produced and transferred to homes and businesses.

For P6, you need to create a poster showing what happens at each stage of electricity production. Make sure you have also explained what happens in each step.

For P7, you need to make a model of the national grid. We will do this by making a model in class, but you can read about what you're making here.

Chemistry P2, P4, P5

Today we'll be working on different bits of the Chemistry section. Check which ones you need to do and go to the questions below:

P2:
You need to draw a graph showing how the current decreases when the length of wire increases. Use the sample graph and the results below to make your own graph.         

Current (amps)	Length of wire (cm)
2	5
1.7	15
1.4	20
.8	25
.4	30
.1	35

P4:

1. You need to name the elements in group 1 and group 7 of the periodic table.
2. You also need to write the equation for sodium and oxygen, chlorine, and water.  
3. Finally, you need to explain how the reactivity of elements changes as you move down a group.

P5:

1. Define the rate of reaction.
2. Name the factors that affect reaction rates (Temperature, concentration, surface area, catalysts)
3. Explain HOW each of the factors makes the reaction happen quicker.

Biology P4

For Biology P4 you need to explain how human activities are affecting the environment. You can do this as leaflets or a poster.
Summarise how the following activities are changing things:

• Deforestation
• Over fishing
• Whaling
• Pollution

Say what each one is, then give a breif summary of the problems it causes. This will meet P4.

Biology P6

Today we're going to complete an assignment on homeostasis, which is how the body keeps certain things at a constant level. Watch this video and then use the links below to complete leaflets about the different topics.

For leaflet 1 (title: Controlling temperature):

1. Explain what homeostasis means:
2. Explain some different ways that the body can stay warm or cool down.

For leaflet 2 (title: Blood sugar levels):

1. Explain how insulin and glucagon control blood sugar levels in the body.
2. What happens when someone has type I diabetes?

Chemistry P7

Today we're going to look at Chemistry P7, which is about how volcanoes are formed. Use the links below to answer the following questions on a poster.

1. How are volcanoes formed?
2. Which gases are released in a volcanic eruption?
3. What are tectonic plates? What do they do?
4. How are mountains formed by tectonic plates?



Make sure you also include a diagram of a volcano.
