Learning ObjectivesUnderstand how protons, neutrons and electrons make up an atomBe able to digitally build an atomStart to differentiate between types of radioactive decay

Success critsLabelled diagrams of atoms; matrix of radioactive decay types; a smile.

The big picture/steps to understanding are......1. What particles make up a nucleus? How are they

different? We’ll watch a clip, discuss and draw a labelled diagram.

2. How does this relate to elements? I’ve seen this in the periodic table but how are they linked? We’ll watch another video, draw a quick sketch and then practice this by building atoms on a website.

3. What is radiation/radioactive decay? What are the different types? You’ll do some independent work here to research how they are different – choose how to present your notes in your books for homework.

Basic atomic structure

Watch. Draw diagram. Label. Shade in if time.

A suggested start for your diagram....

What particles are found here – and what charge and

mass do they have?

What’s this called? What charge does it have? What mass?

How does this relate to elements in the periodic table?

Right – explain these!

Practice!

Now it’s over to you.Planners out please. Write down that you

have Science homework, to be handed in first lesson with me next week.

Your homework is to create notes on the three different types of radioactive decay. My expectations:◦At least half a page per type◦Mix of text/shaded & labelled diagrams◦ Includes info from more than one source ◦Presentation, literacy, effort all top drawer

Last main taskSpend the rest of your lesson

time researching & reading up on the three main types of radioactive decay◦Alpha◦Beta◦Gamma

Use BTEC texts, laptops, 3GAt least 10 minutes NO WRITING

“An element’s atomic number shows the number of electrons in a nucleus; it’s mass number is the number of electrons and protons surrounding the nucleus.”
