SCIENCE UNIT


Level: 4th grade of primary

AIMS

CONTENT AIMS:
  1. Identify and describe our digestive system
  2. Define the parts of this system
  3. Explore and understand concepts related to digestion
  4. Learn the food  pyramid and what it means
  5. Learn the main nutrients our bodies need
EFL AIMS:
  1. Express orally views and experiences in small and large groups communicating with classmates.
  2. Foster children’s confidence in the use of the English language.
  3. Prompt the development of children’s ability to listen attentively and respond appropriately, in a variety of contexts.
  4. Enable children to communicate clearly, using forms of speech appropriate to the occasion and purpose.
  5. Develope writing skills for a range of purposes and audiences, using correct spelling, punctuation and syntax confidently.
  6. Promote independence in written tasks and encourage children to evaluate their own work.
LITERACY AIMS:

  1. Broaden and enhance children’s command of literacy skills, by providing them with a range of different contexts in which to use and practise these skills.
  2. Explore and experiment with sounds, words and texts.
  3. Link sounds to letters naming and pronouncing the letters of the alphabet.
  4. Identify the main events and characters in stories and find  specific information in simple texts
  5. Create short simple texts on paper that combine words with images
MATERIALS

-          Worksheets
-          Videos / games
-          Pictures
-          Computers: internet
-          Textbook
-          Plasticine
-          Visual organizers
-          Science article
-          Products of a supermarket
-          Flash cards
-          Subject-specific glossary 

LESSON 1:

The first step is to activate prior knowledge. For this purpose, the teacher introduces a listening task in which the main characters will mention the important parts of our subject.
1.      Students look at the comic and listen to the story.

Where are Dr. Small, Tom and Laura?

2.      They listen to it again and at the same time, in their notebooks, they have to write the words they have really understood; after that, the teacher interacts with the students asking them ‘what are you listening to? What organs do you see?’
3.      All together aloud ,we brainstorm the  parts of the digestive system
4.      We make a hangman in order to develop their spelling. 

Play code: hitbffeaecjb

These are the hints given to the students so that they guess the part that belongs to the digestion:

-          Moves food down to be digested
-          Where most nutrients are absorbed
-          Where the waste exits the body
-          Where water is absorbed
-          Stores energy, vitamins and minerals.
-          Highly acid to break down food

5. The teacher revises the present simple making questions. Firstly, the teacher gives some examples and then students have to make and answer questions in pairs, writing them down in their notebooks.
Examples: What is the favorite food of your sister?
What do you like most: chips or sausages?
Does your bother love pasta?

Before moving on to the other step! The whole class will play an interactive game about the present simple.


6.    Make a cut-out: the teacher hands out one sheet per couple.
One student cuts the organs’ pictures and the other the organs’ names, then they have to match and stick each part with their own name.

v  WORKSHEET: (work in pairs) cut and paste each part with the name



LESSON 2



  1. Watch a video about how human body works


2.  Again we watch the video, but this time each student will have a sheet where they have to complete the gaps (these gaps are related to the moment when the parrot talks)




3. Word pairs game
Each pair has a sheet, both pupils have to cut it and start the game. The one, who has more pairs, wins




4. Crossword

















LESSON 3



  1. We read and understand ‘the story about a hamburger ‘; after that, students will have to answer some questions:

Where does the digestion process begin?
And where does it end?
Where are the gastric juices?
Why does our body need nutrients?
2.      Personalize the topic by doing a comic in groups of three in which they have to draw the process of another food. Meanwhile, the teacher walks around the class making questions about the type of food they have chosen.



LESSON 4

1.   We will work with the textbook for learning the complete definition of each part. The teacher asks for volunteers that want to read aloud, in order to practice their pronunciation.



2.      With these two flashcards which will be handed out, students have to answer right or wrong depending on the card they raise.


v  The large intestine is like a mixer
v  In the mouth the food is mashed and mixed until it forms a liquid.
v  In the small intestine the nutrients from the liquid food mixture are extracted
v  The stomach is a tube
v  The digestion process begins in the esophagus.
v  The food mixture do not necessary leaves the body through the anus.

3.      In pairs students have to complete this visual organizer writing in order the stages of the digestion and color each square.



4.      When they have finished the last activity, the teacher gives the students Plasticine® to build their body, modeling the parts of that system.  



LESSON 5



1.             In order to change the subject, students have to complete another graphic organizer: “K.W.L. chart”. Before that, the teacher explains to them that they should move to another step which is the food pyramid.


2.      In groups students have to describe photos related to healthy food and fast food. Each one will have a photo; thus, they have to reach an agreement on the description and characteristics of their photo. When they have finished, the teacher will ask some groups to describe their picture. 







-          Involving in our culture, we read together an article published in Science Daily about the obesity problems in children. Then the teacher will make some questions to his pupils.


v Do you like fast food?
v Is it healthy?
v How many days per week do you eat fish?
v  What is your favorite meal? Why?
