1. Watch the video explainer  - section 1 - below which will guide you through what you will be doing and how to get started.

2. Set up your own personal Padlet wall. Link below. You don't need to do more than that right now.

3. REGISTER your project using the google form linked below. There is also a link on Mr Jackson's introduction instructions

4. Use the diagram and the checklist in the last column to give you a heads up on which sections you will need to include. Your wall is personal, so you can customise your presentation however you  like, as long as the project title and sections are clearly visible.

5. Learn how to use Padlet - there are lots of different layout options and ways to present information, so you can get really creative!  How to use Padlet video below.

1. Watch the section 2 video explainer below.

2. Decide on a Science fair topic. Use the links below as well as the video explainer plus your own internet research to help you.

3. Make sure your project is something you can do at home! You can be completely creative, but don't pick something that needs specialist equipment, or something that will cost loads of money! You also need to be able to carry out an EXPERIMENT and collect some data.

4. Start to form a question in your mind that you are going to try and answer.

It doesn't have to be an incredible piece of technical science, (although maybe it will be!), it could be as simple / bizarre as
>'Can you tell which bottled water is the most expensive just from its taste?'
>'Which flavour ice cream melts the fastest?'
>Which Lego car design is the fastest at rolling down a slope?'
>Which flavour tea is the best, according to my family?'
or the slightly sinister
>'Can I use operant conditioning to get my little brother to leave my stuff alone?

1. First, watch the  Section  3  explainer video below . It takes a few seconds to get going so be patient!

2.Use the guidance document below to help you write your aim, background research and hypothesis.

3. THEN watch the OTHER video explainer  below called 'adding information to your padlet wall'  to see how you can lay out your wall and add information in many different ways. It's a different video from the first one - make sure you watch it

4.  Now add your aim, hypothesis and background research sections to your Padlet wall and start laying out your project!

# data[].attributes.attachment_link.title
Section 3 - Aim, Background information and hypothesis

# data[].attributes.body
1. Have you collected all your data? Now watch the section 6 video explainer below

2. Next, draw your results tables and graphs, and add them to your Padlet wall. You can use Google sheets / Excel, or you can draw by hand and upload a photo. Video guide to graphing with Google below.

3. Use the results tables and graphs sections in the attached skills booklet if you would like to use the usual checklists for guidance.

# data[].attributes.body
1. Watch the section 7 video explainer below.

2.What did you find out ? Write a conclusion and make sure you back up what you say with data from your experiment.

3. Try and use your background Science to explain what you found out.

4. Answer the question you wrote for your aim. Sometimes, you don't really find everything out, and that's fine. You can say what you expected to find out, and to what extent your results seem to be different from that.

5. You can use the conclusion section in the skills booklet attached below for extra guidance.

6. Add this section to your Padlet wall. Again, lots of ways to do this, use the way you like best.
