Good morning Kids,
As soon as I can I will give your Social Science marks.
Today is the Earth Day and this year is specially dedicated to bees 🐝 because they’re important in our planet and in our lives.
Today In English I want to do a big review of grammar because you will do an English exam soon: Tuesday, 28 th of April.
We will also work some Natural Science. I prepared a summary to review about the heart parts and its movements and you will also read about how blood circulates in our circulatory system.
ENGLISH
1) Time to review the irregular verbs past tense with this well known game for you. Just one thing: When you will see “present participle” it refers to an “-ing verb”. Example: playing, running. Ok?
Play during10 minutes.

Now you will start practicing grammar. 💡Suggestion: Copy on your notebook the wrong sentences after you checked them on the computer and translate them in Spanish. It will help you to understand them better and see the mistake.

NATURAL SCIENCE
1) THE HEART REVIEW
Watch this video again about the heart:

-What is the heart?
Our ❤️is a very strong muscle that pushes blood all around our body. Its movements allow blood to achieve different areas in our body to provide them with oxygen and nutrients (minerals, vitamins from food) Once these substances are given to our cells and organs, the red blood cells get waste substances from them to keep them clean. And once more, blood comes back to the heart again to be pushed to the lungs and to expell the waste substances and get more oxygen.
-Structure
If you remember, our ❤️ is formed by four parts or chambers (cámaras):
- Two atrium (aurículas): The right one and left one. They are on the top.
- Two ventricles (ventrículos): The right one and left one. They are at the bottom of the heart.
Both sides of the heart, the right and the left one, are separated by a cell wall called “septum”. The septum avoids blood rich in oxygen and blood rich in waste substances be mixed. In this way blood 🩸 rich in oxygen is not contaminated and it gets clean and safe to our cells and organs.
- The heartbeat 💓
The ❤️ pushes blood all around our body through two different movements:
- One expands our heart and allows the entrance of blood rich in oxygen or waste substances as carbon dioxide in the atriums placed on the top. This is the DIASTOLE MOVEMENT.
Then blood passes to the two ventricles through the valves (remember: the valves work as a door)
- The other movement consists in the contraction of the heart to push blood 🩸 to the lungs or to the rest of the body. This is the SYSTOLE MOVEMENT.
Here blood that is in the right ventricle is pushed to our lungs through the pulmonary artery and blood in the left ventricle is pushed to our body cells and organs through the aorta artery.
In this video you will see how the ❤️moves in detail:

2) Time to do some activities!
- Read page 27: The circulatory system.
- Page 27, activities 4, 5 and 6.
AND THAT’S ALL KIDS!
