This worksheet is designed to help students understand the
Human Life Cycle by comparing what people can and cannot do at different stages of life. The goal is to fill in the blanks using appropriate actions that match each developmental stage — baby, toddler, child, adult — while using the given conjunctions: *but*, *however*, *although*.
Here’s a logical and age-appropriate solution:
---
✔ A baby can _cry_ but it can’t _walk_.
> Babies are born with reflexes like crying to communicate needs. They cannot yet walk — that typically develops around 9–12 months.
---
✔ A toddler can _walk_ however it can’t _read_.
> Toddlers (ages 1–3) usually learn to walk independently. But reading requires advanced cognitive and language skills they haven’t developed yet.
---
✔ A child can _ride a bike_ although it can’t _drive a car_.
> Children (roughly ages 5–12) often learn to ride bikes. Driving a car is legally and physically beyond their capability until adolescence or adulthood.
---
✔ An adult can _drive a car_ but it can’t _grow taller_.
> Adults have reached full physical maturity, so they generally stop growing taller. Driving a car is a common adult responsibility (with a license).

📌
Note: You may use slightly different verbs as long as they are developmentally accurate and grammatically correct. For example:
- “A baby can _smile_ but it can’t _talk_.”
- “A child can _go to school_ although it can’t _vote_.”
But the answers above are simple, clear, and widely relatable for young learners.

Educational Goal: This activity teaches:
- Sequencing of human development
- Use of contrastive conjunctions (*but, however, although*)
- Real-world understanding of abilities at different life stages
