Unit Title: Nechako White Sturgeon- our local prehistoric giant Subject: Science Grade(s): Intermediate Number of Lessons: 7 Time: 2-3 weeks Rationale/Overview: The purpose of this unit is for the students to gain a deeper awareness of the endangered Nechako white sturgeon and the many challenges the species currently face. Students need to be aware of local issues in order to connect to the Nechako watershed. Background and Teacher Preparation Required: It would be beneficial if the students have already learnt about the Nechako river (see the Nechako Watershed unit plan). The teacher touches base with local expert(s), such as Cory Williamson or Brian Frenkel of the Nechako white sturgeon Recovery Initiative (www.nechakowhitesturgeon.org). Cross-Curricular Connections: Math, Fine Arts, Language Arts, Social Studies, P.E. Extensions and Adaptations: We recommend that this unit is followed by the Riparian Zone lesson or unit plan. That way, students develop a more thorough insight into the complexity of the Nechako watershed and their role in it.

Introduction Instructional Objectives: Teaching Strategies: Student Activities: Assessment Materials StudentI can participate in a discussion about the Nechako white sturgeon and explain what an endangered status means. Invite students to brainstorm what they know about the Nechako white sturgeon Brainstorm prior knowledge Observation SMARTBoard Participate in discussion Discuss the concept “endangered”. What does it mean? What caused the sturgeon to be endangered? Who decides on an Endangered status for species? What is Canada’s Species at Risk Act (SARA)? (background information found on sheet Endangered Species…) Listen to story and respond throughout the read aloud. Ticket Out the Door “What does endangered mean?” Large visual/model of the White Sturgeon or Powerpoint Presentation: Why is the White Sturgeon Special? Read the book out loud and invite students to respond to the story and new knowledge on chart paper. Talk about sturgeon being endangered, due to: hydroelectric dam construction: reduced eliminate spring flooding, block access to spawning sites, trap nutrients on which salmon depend, Art activity “Pre-historic fish” (view local artist Annerose Georgeson’s website for inspiration!)

(Check Annerose’s website!) Cut out image. The images will be placed on to bulletin board on the right hand side (more images will later be added to complete the display) 2. External Anatomy Student can identify 5-10 external parts of the Nechako White Sturgeon. Use large visual of sturgeon and distribute Worksheet. Observe the visual and think of the purpose of each feature. Present the external parts and their functions (discuss with students). Identify external parts while teacher presents and record on the worksheet. After a class discussion, provide students with art material and ask them to recreate a White Sturgeon with at least 5 features that they can explain the functions of to someone. Participate in discussion. Recreate a sturgeon that has at least five features that the students can explain the function of. Create a model of a sturgeon where 5-10 features are apparent. Be able to explain what and why they are by presenting it to a partner, small group or the class. SMARTboard or visual PowerPoint Presentation: Parts of the Nechako White Sturgeon & Sturgeon PPT Cora M. Image: White Sturgeon Anatomy Image Worksheet Student Handout Part A: White Sturgeon Anatomy Sheet External Anatomy (answer key) Clay or paper and water for paper mache or other art material 3. Survival Student can reflect how adaptations have either helped the sturgeon survive. OR sturgeon adapt and evolve slowly, which is helping them go extinct Briefly review last lesson. Recall what they learnt last time. Brainstorm the word “adaptation” and relate to human experience: how do you adapt to the cold? The heat? Participate in brainstorming and class discussion. Using the knowledge from last lesson, think about how the external features help the sturgeon adapt to their environment? Whiteboard Observation and work sheet. Markers DFO document: Backgrounder White sturgeon in BC The class compares sturgeon to other fish. Students answer questions with partner on Adaptations sheet Worksheet: Adaptations Map of the Nechako Watershed Compare sturgeon to any other fish that you know: -small eyes, large barbels, heterocercal tail, body shape, shape of mouth, scutes, colour above and below the sturgeon (teacher can write/draw on the board) Hand out Adaptations sheet for students to answer (in partners). 4. Circle of Life Student can illustrate the life cycle of the Nechako White Sturgeon. Invite local expert to share information about life cycle and habitat (if possible). Brainstorming/Check Prior Knowledge about what students know about the life cycle of the Participate in discussion Participate in group work (expert groups). “Research” (by looking at Ticket out the door: show me what you know of the life cycle of the sturgeon.

Each group is the expert of their assigned/chosen stage. clay Life cycle poster available at Avison’s Management in Vanderhoof PowerPoint display Life cycles of a Sturgeon Students create images of their stage of the life cycle. Support sheets in curriculum package Students add images to bulletin board. Divide students into expert groups. Each group chooses a stage in the life cycle of which they become experts and then share with others (or do a gallery walk in the classroom). Art supplies Bulletin board TV for video Hands-on art activity: Each group creates images of their stage of the life cycle to add on to bulletin board. 5. A Sturgeon’s Habitat Student can explain how the habitat of the Nechako White Sturgeon has changed from functional to dysfunctional. Discuss what we know about a functional habitat. (Habitat meets the needs of the organism) Ask the students: How come the sturgeon has been able to adapt to its environment for millions of years, but in the last 100 years it has become an endangered species? What made its habitat dysfunctional? (See support sheet) Students share ideas regarding what they know about habitat. Reflect upon what has happened in the last 100 years that made the Nechako white sturgeon’s habitat dysfunctional. Students create a skit/dramatization. Students create objects essential Presentation of a newsflash about the “sensation” of the decline of the Nechako white sturgeon. SMARTboard PowerPoint Presentation: Saving the Nechako white sturgeon PowerPoint Nechako White Sturgeon Sheet Sturgeon Habitat a What is being done? (Local restoration projects) in functional habitat (i.e. rocks, gravel, bubbles, bugs, salmon) to add to bulletin board. Computers Support sheet for teacher (background knowledge): Salmon Habitat With a partner, create a newsflash where the issue of the Nechako White Sturgeon’s changing habitat is “the big news.” Dress-up clothes? Hands-on art activity: Create objects for sturgeon habitat on bulletin board. Bulletin board Art supplies 6. Nature Hike to spawning/ feeding/ wintering site Students record observations during the nature hike activity. Vanderhoof: spawning grounds Murray creek Ft St James: Feeding, wintering Ft Fraser: Feeding Fraser Lake: feeding and wintering Burns Lake: potential to go on a field trip to visit different sites that the Nechako white sturgeon are found The teacher takes the students on a hike to the spawning/feeding/wintering site in the Nechako River (Riverside Park) or another suitable location in the Nechako watershed. Meet up with local sturgeon expert. Local expert and the teacher encourages discussions about the sturgeon; history, anatomy, life cycle, habitat, and what the students remember most from learning about this. Also emphasize the changes to the river and adjacent sloughs or riparian zone. Hand out Sturgeon Habitat Study sheet for students to complete. Students go on a hike, participate in discussions about what it is like for the sturgeon in its changed habitat. Students fill out the Sturgeon Habitat Sheet (encourage complete sentences and details). Recording observations. Guest: Local Expert Good footwear and appropriate clothing. Nature Guide Cameras/phones and/or science journals? Pencils Hand-outs: Sturgeon Habitat Sheet Jars to collect sturgeon foods Thermometer for water temperature 7. What Do YOU think? Student can share what Nechako White sturgeon means to them. Facilitate a discussion about the main highlights and discoveries about the Nechako white sturgeon. The teacher asks the students to share what value the Nechako White Sturgeon has in the students’ personal lives and what it would mean to them if the Nechako White sturgeon becomes extinct? Future: Release of a Sturgeon Students can participate in sturgeon release event. The teacher brings students to the Vanderhoof Recovery Facility and hatchery, where the students get the opportunity to participate in a sturgeon release. Students review what they have learnt and share new insights with the class. Journal write Science journals Share orally (either in class or in small groups) Pencils Students think and write about what value the Nechako white sturgeon holds for them and what it would mean to them if it becomes extinct. The students participate in sturgeon release. Erasers Participation in sturgeon release. Appropriate outdoor clothing. Data recording skills practiced.
