-Most of them had more difficulty dealing with part B which included open questions.
-A few students answered beforehand and were asked to draw a picture of the skeletal system with the main parts on the back of the worksheet.
-Two students started crying because they couldn't answer part B. They were reminded that it was just a diagnostic test.
-Other students got stuck in part B, so they were asked to draw the picture of the skeletal system.

N° of students: 22.

1. A student said the prayer.
2. Students showed the teacher what they had found about the digestive system as homework.
3. Students were asked to look at their workbooks page 48. They read the instructions and a few of them asked questions about what they were expected to do.
4. Other students were asked to explain them what they had to do. Students had to read some statements about the digestive system and say if they agreed or disagreed with them but they had to provide evidence based on information from the materials they brought for their portfolios or they could look for information on their books pages 152-153.
5. Students worked in groups of three to gather the information they needed.
6. While students were working in groups, the teacher called each group to his desk and showed them a short video that showed how nutrients were absorbed in the small intestine.
7. Students gave their answers and then were asked to explain the path food follows after it enters the mouth. Students explained the process based on what they had just read and the pictures they had.
8. Students were able to get to the conclusion that most of the digestion takes place in the small intestine because it is there that the nutrients pass to the blood to be taken to the whole body.
9. Students read tthe statements in their workbooks and students from different groups gave the evidence to support each answer and said where exactly they had found the evidence.

Remarks:

-Students were willing to start the class. Some of them were waiting for the tacher at the door with their portfolios to show him what they had brought about the digestive system.
-Some students wanted to form their own groups. The teacher told them about the importance of working with other students different from their best friends.
-When students were working in groups, some of them led the discussion asking, "Do you agree or disagree (with the statement)? The others pointed to the part of the book or the materials they had where the evidence was.
-After watching the video that showed how the nutrients were absorbed in the small intestine, students were even more enthusiastic trying to answer the questions in their small groups.
- Students were very happy when they confirmed that their answers to the workbook exercise were right. Most of them were very willing to participate.

Inquiry-based lesson 9: The nervous system
N° of students: 22

1. A student said the prayer.
2. Students were told that they would do an experiment in which they would watch some pictures of animals with the names of each animal on top. They would work in pairs and time each other to observe how long each one of them took to name all the animals.
3. Students worked in pairs. They looked at the pictures of animals with the names on top of them and recorded how long each one of them took to name all the animals.
4. Students shared their results with the class.
5. Students were asked to do the same, but this time the words on top of the animals did not match the animals. They were asked to ignore the words and name only the animals.
6. Students worked in pairs again and recorded how long it took each one of them to name the animals ignoring the words.
7. Students had more trouble this time naming the animals since the words did not match the pictures so they took longer naming all the animals.
8. The teacher asked students what part of their bodies was responsible for the change in how long it took them to name the animals.
9. Students answered that the brain was. Students were encouraged to ask questions related to the brain. Some students said it was part of the nervous system.
10. Students said what they knew about the nervous system and its parts.
11. Students watched an interactive presentation about the nervous system at this website: http://kidshealth.org/misc/movie/bodybasics/bodybasics_brain.html

12. The program asked them to repeat the names of the main parts of the nervous system and they did so.
13. Some students were asked to read aloud the brief explanation about the function of each part of the nervous system.
14. Students were asked to discuss in small groups the conclusion they could draw from the experiment based on what they had observed about the nervous system.
15. Students concluded that since different parts of the brain control different actions, there was interference of one part of the brain on another when trying to name the animals with the mismatching words on them.
16. Students were told that in the next class there would be a general review of all the systems of the human body studied so far. They were asked to review at home all the materials they had collected throughout the inquiry-based unit and to include in their portfolios any other material they found.


Remarks:

-Students liked the idea of going out of the classroom to the auditotorium to do the experiment.
-Some students were very anxious about the experiment and they couldn't wait to get started.
-A few students had trouble timing their peers since they did not have a cronometer. The teacher asked them how they could time their classmates without a cronometer. A student suggested that they could count while closing and opening their right hand.
-Students realized that it took them more time to name the animals when the words did not match the pictures.
-Students were very involved in the activity in which they had to repeat the names of the main parts of the nervous system and almost all of them wanted to participate reading aloud the definitions of the different parts.

7. Students shared their findings with the class and made any necessary corrections.
8. Students were told that in the next lesson they would have the opportunity to demonstrate how much they had learned in the inquiry-based lesson by taking a post-test.
