Energy Web

4 Part 4: Language Frames (Speaking & Writing)

Fill in the blanks using words from the diagram

1 Explain a Producer:

The algae is a because it makes food using .

2 Explain a Primary Consumer:

The water beetle is a because it eats .

3 Trace the Energy Flow:

Energy flows from the to the because the trout eats the beetle.

4 Explain the Apex Predator:

The osprey hawk is at the of the pyramid, so it has the (most / least) energy.

Oral Practice: Read Frame 3 out loud with your partner! Check each other's answers.

Step-by-Step Facilitation & WIDA Scaffolding Protocols

Teacher Reference

Crucial ESL Level 1 Misconception: Arrow Direction in Food Webs

Almost all beginning language learners assume the arrow points from predator to prey because the predator is "stronger" or "attacks". Correction Protocol: Write "Grass ➔ Deer" on the board. Point to the arrowhead and state: "Energy moves INTO the deer's belly. The arrow is an energy delivery truck!" Have students physically point their arms forward to model the delivery.

Phase 1: Visual Vocabulary & TPR Intro (Slides 1-5) Choral Practice

Introduce one trophic level at a time. Have students repeat the term 3 times (whisper, normal, loud) while performing the TPR hand gesture. Explicitly reference the Spanish cognate (Productor, Consumidor) to leverage home-language literacy.

Phase 2: Structured A/B Partner Routine (Slide 7) Speaking Scaffold

Pair Level 1 students strategically with a bilingual partner or Level 2 peer. Partner A points to an organism on Slide 7 and asks the prompt. Partner B must use the sentence strip. Circulate and stamp/praise full sentence completions rather than one-word answers.

Phase 3: Graphic Organizer Practice Sheet (Pages 1-2) Writing Scaffold

Model Item 1 of the Pyramid tier on the board first. Highlight that the biggest tier is at the bottom (Producers = 10,000 J). Encourage students to use their colored pencils (Green for Producers, Blue for Primary, Purple for Secondary, Red for Apex).

Differentiation Guide for English Proficiency Levels

WIDA Level 1 (Entering) Scaffolds

• Allow pointing, circling, and letter matching on Part 1.
• Provide pre-cut word tiles for the Energy Pyramid tiers.
• Accept oral answers with sentence frame fill-ins.
• Encourage the use of home-language scientific glossaries.

WIDA Level 2 (Emerging) Extensions

• Require students to write a complete sentence explaining why 90% of energy is lost as heat.
• Challenge them to add a decomposer (fungi/bacteria) to the web.
• Have students predict what happens if all primary consumers disappear.

Quick Formative Check (Thumbs Up / Side / Down):

"Does the arrow point to the eater or to the organism that gets energy?"

Target: 100% Correct

Part 4: Language Sentence Frames Solutions (8 Points)

2 pts per frame (1 pt concept, 1 pt vocabulary)

1. Producer Frame:

"The algae is a producer because it makes food using sunlight (or the Sun)."

Acceptable: "light", "sun", "solar energy", "photosynthesis".

2. Primary Consumer Frame:

"The water beetle is a primary consumer because it eats algae (or plants)."

Acceptable: "green plants", "producers", "leaves".

3. Energy Flow Frame:

"Energy flows from the beetle to the trout because the trout eats the beetle."

Caution: Ensure students put beetle FIRST and trout SECOND, showing energy direction!

4. Apex Predator Frame:

"The osprey hawk is at the top of the pyramid, so it has the least energy."

Key concept: 10 Joules is the LEAST amount of energy in this pyramid.

WIDA Level 1 Evaluative Scoring Matrix

Approaching (1-2 pts)

Identifies 1-2 trophic levels with extensive teacher prompt; reverses arrow flow; leaves frames partially blank.

Proficient Target (3 pts)

Accurately identifies all 4 trophic levels; correctly places organisms in pyramid; completes frames with word bank support.

Exceeding (4 pts)

Explains why energy is lost (heat/metabolism); reads frames fluently to partner; traces complex multi-path food webs.
