Physics P1 and P2

Today we're going to start the first radiation assignment. Answer the following questions in a powerpoint:
For P1:

1. What particles make up the nucleus?
2. What is radioactive decay? How is it caused?
3. Define what half life means:

Make sure you also find some diagrams to illustrate your answers!

For P2:

1. You need to complete a table about the different kinds of radiation. Copy and complete these headings:

Type of radiation

Structure:

Stopped by:

Uses:

You may need to find some more resources, as well as using the link above.

For M1:
You need to explain what the half-life of an element is (giving both definitions), using a graph to help make it clear. Are half lives the same or different for different elements? You should also include some examples of different half lives.

For D1:
You need to show how you can calculate the half life of an isotope. Create 2 sample questions and the mark schemes that the students can use to practice the calculations.

Pollution Indicators

Today we're going to finish the assignment about indicators of pollution.

• Make sure you've written up three experiments for temperature, oxygen levels and pH using the writing frame on the shared area.
• You also need to draw three graphs using the sample sheets that Mr. Cole will give you . Once you've done these, you can work on merits for other assignments.
