Digestive System (Cut-and-Assemble) - Libras

WATCH THE VIDEO OF THE COMPLETE ACTIVITY

⚠️ This material is an adapted Science/Biology activity with an illustrated summary (it is not a complete theoretical workbook on the topic).

Number of questions in the activity:

6 adapted questions + complete answer key, distributed across 6 activity pages, including a hands-on cut-and-assemble Digestive System activity.

The sequence begins with simpler identification and recognition activities. Gradually, students explore the path traveled by food, organs and structures of the digestive system, substances involved in digestion, and the location of organs within the human body, concluding with the hands-on assembly of the system.

Target audience:

The material was developed primarily for deaf students who use Brazilian Sign Language (Libras), especially those who require greater linguistic accessibility to follow the Science/Biology content taught in class.

It may also benefit deaf students learning written Portuguese as a second language (L2), students with Intellectual Disabilities associated with deafness, and students with ASD associated with deafness, as well as students who benefit from visual, concrete, and hands-on learning activities.

It can be used by Science and Biology teachers, bilingual teachers, Specialized Educational Support (AEE) professionals, and other educators who work with deaf students.

Content covered:

The activity addresses the Digestive System; path traveled by food; mouth; esophagus; stomach; liver; pancreas; small intestine; large intestine; saliva; bile; gastric juice; location of organs within the human body; and spatial organization of digestive system structures.

Important for the teacher:

One of the main features of this adaptation is its focus on linguistic accessibility. The instructions and different words used throughout the activities are accompanied by representations in Libras while also maintaining written Portuguese. Even the numerical answer choices in the first question include visual representations in Libras.

This organization also supports connections between Libras sign → image → written Portuguese word → scientific concept. In the activity about substances involved in digestion, for example, students observe the mouth, liver, and stomach, identify the corresponding signs and written names, and match these structures with saliva, bile, and gastric juice.

In the following stages, students use a word bank to name individual structures and then identify those same organs within a complete representation of the human body.

Finally, question 6 transforms the content into a hands-on learning experience: students cut out the digestive system pieces and organize them within the human body shown on the following page, analyzing the position and spatial relationships between the different structures.

Key Features:

✅ Integrates Libras, written Portuguese, and Science/Biology, increasing accessibility to Digestive System content.

✅ Supports deaf students who are learning Portuguese as a second language (L2) by allowing them to connect signs, images, and written words.

✅ Organizes learning progressively: identify → sequence → associate → name → locate → assemble.

✅ Explores not only the names of the organs but also the path traveled by food, the location of structures, and substances involved in digestion.

✅ Includes a hands-on cut-and-assemble activity, also supporting visual-motor coordination, manipulation skills, and spatial organization.

✅ Uses large anatomical images, a word bank, and different response formats, reducing exclusive reliance on reading and writing.

✅ Includes a standard version, an UPPERCASE version, and a complete visual answer key.

✅ Saves approximately 9 hours and 59 minutes of teacher preparation time.
