Lesson 1 - Systems

In this lesson, the children were introduced to the concept of a system. They begin to understand that components can work together to perform a task. Finally, the children explored how digital systems work and learned about physical and electronic connections. 

Key vocabulary: system, connection, digital, input, process, output

Have a look at some of our designs of our very own 'digital teds'. We were able to explain our input, process and output to our class.

We then looked at a different types of crossing and evaluate these using the sheets below. Finally, we discussed how the use of the sensors within the system of a puffin crossing can help us.

Lesson 3 - To experiment with search engines

The children were introduced to a range of search engines. They were given the opportunity to explain how to search, before they write and test instructions. Next, they learned that searches do not always return the results that someone is looking for, and refine their searches accordingly. Finally, learners were introduced to the two most common methods of searching: using a search engine and using the address bar.

Key vocabulary: search, search engine, refine

We had lots of fun testing out each others instructions on how to search for the answer to a question. Next our teacher gave us the search term rugby and we had to evaluate different search engines, have a look at our work below:

Lesson 4 - To describe how search engines select results

The children gained an understanding of why search engines are necessary to help them find things on the World Wide Web. They conducted their own searches and break down, in detail, the steps needed to find things on the web. They then emulated web crawlers to create an index of their own classroom. Finally, they considered why some searches return more results than others.

Key vocabulary: index, crawler, bot, search engine
