Structures ( Year 5, Natural Science)

What is a structure?

A structure is a group of elements which can support weight. There are two kinds of structures:

• Natural structures: The skeleton.
• Artificial structures: A shelf.

The resistant of the structure depends on the material and the shape. 

Let's think on different structures you can have around you in your daily life. We are going to do it using a Cooperative Learning Technique: Let's spin the sheet. Think on one structure: the name of it and a picture. Use your notebooks so at the end each member of the group will have the four different structures. In the following presentation you will know how to work with this technique.

BRIDGES

Let's have a look to the following video, along it you will have some questions to answer it. 
It will be an assesment tool, but for that you have to register on EDpuzzle. To join your class you can use Edmodo user and password. We have created two classes, enter the code to join them:

• Year 5A: Code: onpepfu. Link to the class: https://edpuzzle.com/join/onpepfu
• Year 5B: Code: huereje. Link to de class: https://edpuzzle.com/join/huereje 

Bridges are structures that can support very large forces. They can support:

• Their own weight.
• The movement caused of the wind and the cars.

There are different kinds of bridges depending the structure:

• Bridges made up of arches, usually done by stones.

Let's investigate a bit about famous bridges. You will choose one bridge and investigate some date you will post in the following padlet. 

• Photo.
• Name and place.
• Architect and the year it was built.
• Kind of bridge and materials.

This website will help you: Hi Comsuption: The 39 most amazing bridges in the world. 

We are going to work in cooperative groups so each role will have mission to do.

• Leader: Distribute which part each person will investigate. 
• Scribe: Check all the information is complete before uploading into the padlet.
• Recorder: Write down everybody information into the padlet.
• Time Keeper: Be sure everybody does the task in 15 minutes.

Review Activities for English. (Present Cotinuous, Past and Compartives)

At the end of the whole topic it would be a great idea to review. With the following activities you will be aware about all your knowledge. So you will decide if you need to go back over any parts of the topic or if you want to go a bit further with something. 

Along this topic we have learnt about:

• The use of present continuous to say what you are doing now. 
• Vocabulary about sports.
• The use of the past to describe in the past or talk about past habits. 
• The comparative adjectives to compare things or people.

The following presentation will ask you to do some task using COOPERATIVE LEARNING.

PAST SIMPLE (Regular and Irregular)

We are going to focus our attention in the PAST SIMPLE TENSE of regular and irregular verbs.

We use the past for talking:

• An action finished in the past.
• Past habits. 

LET'S WATCH THIS VIDEO, WITH A SONG ABOUT THE PAST. 

DOING THESE ACTIVITIES YOU CAN PRATICE WHAT YOU HAVE LEARNT. Remember if you don't practices you won't get it.
