Energy in Living Systems Unit Bundle

Energize your biology classroom with this complete Energy in Living Systems Unit Bundle! This all-in-one resource delivers a clear, engaging, and scaffolded approach to three foundational life science topics—Photosynthesis, Cellular Respiration, and Energy Flow in Ecosystems. Perfect for over four weeks of instruction, this bundle is ideal for both new and experienced teachers looking to build deep student understanding through hands-on labs, critical thinking, and NGSS-aligned lessons.

Students will investigate how energy flows through living systems—from capturing sunlight in the chloroplasts of plants, to converting glucose into ATP inside mitochondria, to tracing energy as it moves through food chains, food webs, and trophic pyramids. With an emphasis on scientific inquiry, real-world relevance, and visual learning, this unit helps students connect complex biochemical processes to the everyday energy needs and relationships that sustain ecosystems.

Why Choose This Bundle?

• Save 10% with this comprehensive and highly-engaging three-unit bundle!
• Features interactive labs, student-choice projects, and visual aids that bring biology to life.
• Encourages higher-order thinking and reinforces learning through diverse question types and assessment formats.
• Designed to build mastery of core life science standards, including NGSS.
• Ideal for middle or high school biology or general science courses.
• Includes pacing guides, study guides, answer keys, and built-in differentiation to make planning stress-free.

What’s Included?

• Photosynthesis Unit – Students learn how light energy is captured and converted into chemical energy through the light-dependent and light-independent reactions. With interactive notes, graphic organizers, practice worksheets, and built-in assessments, everything you need is included—no prep required!
• Cellular Respiration Unit – This unit breaks down glycolysis, the Krebs cycle, and the electron transport chain while helping students compare aerobic and anaerobic respiration. Visuals, real-life connections, scaffolded practice, and hands-on activities are all included for seamless instruction.
• Food Chains, Food Webs, and Trophic Pyramids Unit – Students explore how energy flows through ecosystems by analyzing feeding relationships, modeling energy transfer, and investigating real-world ecological phenomena like keystone and invasive species. Includes two engaging labs, a student-designed food web activity, and a multi-day project on ecological impacts.

BONUS RESOURCES!

• Energy in Living Systems Unit Pacing Guide – Stay organized with a day-by-day instructional plan.
• Cellular Respiration & Photosynthesis Study Guide & Answer Key – Help students review and retain key concepts with this structured guide.
• Cellular Respiration & Photosynthesis Unit Exam & Answer Key – Assess student understanding with a comprehensive, standards-aligned unit test.
• Nutritional Relationships Exam Study Guide & Answer Key – Help students prepare for content on food chains, webs, and pyramids.
• Ecology Unit Exam Detailed Study Guide – Support deep review of major ecosystem concepts.
• Ecology Unit Exam & Answer Key – Assess student understanding with a summative test that covers ecosystem energy flow and major ecosystem concepts.

Make energy transformation meaningful and manageable with this full unit bundle! Whether you’re teaching cellular processes or ecosystem dynamics, this resource helps students visualize, connect, and master one of biology’s most vital topics.
