This Grade 5 Science hard worksheet uses passages on the Great Pacific Garbage Patch and melting glaciers to drive analysis. Students compare ocean cleanup nets with plastic-use reduction, predict the realistic long-term outcomes of a local plastic-bag ban, and identify the chief mechanism by which glacier melt raises sea levels. Five fill-ins reinforce terms like microplastics, gyres, and pollinators, giving Grade 5 learners the vocabulary and reasoning practice needed for environmental science.

Human Impact on the Environment
Part A: Multiple Choice
Circle the best answer for each question.
1. The Great Pacific Garbage Patch is mostly made of ___.
A) Tiny plastic pieces and floating debris
B) Solid metal cans piled high above the waves
C) Crude oil that never broke down
D) Chunks of broken icebergs from the Arctic
2. Melting glaciers raise sea levels MAINLY by ___.
A) Cooling the air above coastal beaches each summer
B) Adding more freshwater into ocean basins
C) Pushing salty water deeper into the seafloor
D) Reflecting more sunlight back into outer space
3. Compare ocean cleanup nets vs reducing plastic use. Which judgment is MOST accurate?
A) Cleanup nets alone solve the entire plastic problem forever
B) Reducing use stops new plastic but ignores existing waste
C) Both reducing use AND cleanup are needed for real progress
D) Plastic pollution will fix itself if humans simply wait longer
4. A coastal town bans single-use plastic bags. The BEST predicted long-term outcome is ___.
A) Ocean plastic vanishes from the entire planet within one week
B) All sea animals everywhere instantly become healthy and safe
C) Local plastic litter on beaches drops over many months
D) Plastic factories close worldwide because of this single town
Part B: Fill in the Blank
Write the correct answer on each line.
1. Plastic pieces smaller than a pencil eraser are called microplastics.
2. Large rotating ocean currents that trap garbage are called gyres.
3. A massive sheet of slowly moving land ice is called a glacier.
4. Insects like bees that move pollen are called pollinators.
5. Global average warming caused by greenhouse gases is called climate change.
