Studying the human body is the most exciting thing for kids! Lungs, heart and stomach are amazing organs that interests the mind of our students.

Here you can find a review of the three organs.
This is a good worksheet to use, after you taught the three organs separately. This resource can be used to prepare them for a test, or even as an informal assessment for you to see where they are.

PPT Introduction

On second grade, when students learn about human body we use a big skeleton on the Science board as a display, so every time that we learn something new about organs, bones, tendons and muscles we add the description and also the organ or body part to the skeleton. That way students can visually integrate what they are learning and what they have learnt.  

I got the skeleton and body parts for free on Pinterest. Here is the link if you want it: https://pin.it/4JVYmIf 

Here is a PPT to help you introduce the subject of human body. It contains some questions you can discuss with the whole group, and explanations about what does each organ do.

I did this ppt with my friend Carmen Ortúzar.

Objective: Identify major organs of the human body.

Have your students watch the following video: https://www.youtube.com/watch?v=zKSqNLT8kAA

After they have watched the video once or twice, tell them to look at the pictures and to read the words from the word bank. Then, tell them to solve the crossword writing the correct name for the corresponding organs. Finally, you can play the video again, making some pauses if necessary, to check the students' answers. 

Use this exit ticket to work with muscles!
Students have to understand that muscles cover and protect the bones.
Fun facts are great! Let them guess how many bones and muscles are in their body!

Watch this video to explain muscles.
Complement it with the ppt review!

OA7: Identify, locate and explain the function of some vital parts and organs of the human body, such as  the heart, lungs, stomach, skeleton and muscles, among others.

With this worksheet, students will be able to apply what they have learnt about the respiratory system and breathing process, by completing a text with vocabulary from the unit.

OA7: Identify, locate and explain the function of some vital parts of the human body, such as the heart, lungs, stomach, skeleton and muscles, among others. 

On this worksheet students will be able to apply vocabulary from the unit on a text. They will also apply what they have learnt about the main organs and processes of the circulatory system.

CN03 OA06: Classify food, identify their effects over human health and purpose good eating habits for a healthy lifestyle.

Once students have learnt about the different food groups, nutrients and the function that each of them has in human body, this worksheet is useful to do a "round up" on this topic. 

cn03oa06:  Classify food, identify their effects over human health and purpose good eating habits for a healthy lifestyle.
cn03oa07: Purpose and communicate good hygienic practices when manipulating food, in order to prevent diseases.

Once students have learnt about different food groups, nutrients and their functions in the human body, his resource can be used either as a review workshTeet, or as an assessment, depending on what the teacher wants to do. 

It includes questions of True or False (false statements have to be replaced by a true statement), multiple choice questions and a part on which students have to connect what they have learnt with their real life, since they need to look in their house to find different types of food, and classify them according to the food group they belong to, or nutrients they contain.
