Free Food Chains science reading passage for grades 3-5. Food-chain arrows are easy to reverse when students picture who chases whom. Chompling makes the direction explicit: energy moves from food to eater. The set then expands from one chain to webs, decomposition, and changing populations.

Simple classroom use
Allow about 25-35 minutes. Introduce Chompling and preview the bold science words. Read the two-page passage independently, with a partner, or aloud with support. Students use numbered paragraphs to locate evidence, choose vocabulary in context and explain science ideas on the response pages. Discuss answers using the 18-point key; accept accurate equivalent explanations and use misconceptions to choose a paragraph to reread.
Use this for science-literacy practice, a reading center, a substitute lesson or preparation for the free Online Adventure. Intended for grades 3-5; younger or developing readers may benefit from adult read-aloud support. No validated Lexile or independent grade-level test is claimed.
A teaching point to discuss
Decomposers recycle matter; energy flows through food relationships and is eventually dispersed as heat. A predator can also be prey, and real food-web predictions should allow for alternative foods and other conditions.
Read each arrow aloud as "energy goes to." Begin with grass and rabbit, then add another consumer and a predator. Ask students which new connections make the model a web and how a change in one food resource might spread.

Optional hands-on science field trip in your classroom
Dig Kits can extend the experience through Discover - Identify - Collect: uncover real specimens, identify them using observations and available specimen/trading cards, then organize a collection. Contents vary by product. Online completion does not reserve kits or record a physical discovery.
Teachers have alternative routes: purchase available Dig Kits directly, explore the Free Dig Kits classroom campaign, or ask their PTA/PTO whether it can fund a classroom purchase. PTA funding is not guaranteed or arranged by this resource. Campaign signup does not automatically guarantee free kits; current funding and fulfillment conditions apply, including full funding and school/delivery confirmation.
