Since this is a research-based worksheet and not a math or logic problem with a single correct answer, I will guide you through how to complete it using an example invasive species: the
Zebra Mussel.
---
Step-by-Step Completion (Using Zebra Mussels as Example):
1.
Name & Date
→ Write your name and today’s date at the top.
2.
Invasive Species
→ *Zebra Mussel*
3.
Scientific Name
→ *Dreissena polymorpha*
4.
Native Location
→ Freshwater lakes and rivers in Eastern Europe and Russia.
5.
Physical Description
→ Small shellfish, about 1–2 inches long. Shells are striped like zebras (brown and white). They attach firmly to rocks, pipes, boats, etc.
6.
Introduction to North America
-
When: Early 1980s (first found in Lake St. Clair near Detroit)
-
Where: Great Lakes region
-
How: Likely came in ballast water from ships traveling from Europe
-
Impact: Clogs water intake pipes, damages infrastructure, outcompetes native mussels, changes water clarity, harms fish populations
7.
Control
→ Chemical treatments, physical removal, filters on intake pipes, public education to clean boats before moving them between lakes.
8.
References
→ List sources like: U.S. Geological Survey, EPA website, National Invasive Species Information Center, textbooks, or trusted educational sites.
9.
Summary Report *(Write this last, after filling out all sections)*
→ Use complete sentences and paragraphs. Example:
> The zebra mussel is an invasive species originally from Eastern Europe. It was accidentally brought to North America in ship ballast water during the 1980s. These small mussels have black-and-white striped shells and stick tightly to hard surfaces. Since arriving, they’ve caused major problems by clogging water systems and hurting native wildlife. Scientists and governments are trying to control them with chemicals, filters, and public awareness campaigns.

✔ You can use this same structure for any other invasive species — like Kudzu, Asian Carp, or Burmese Pythons — just swap in the facts!
Final Answer:
Complete the worksheet using accurate information about one invasive species — such as the Zebra Mussel — following each section carefully. Include scientific name, origin, how it arrived in North America, its effects, control methods, and cite your sources. Then write a short summary report using full sentences and proper paragraph breaks.
Parent Tip: Review the logic above to help your child master the concept of invasive species worksheet.
