Description

Plants vs CO₂ is an educational science game inspired by tower defense mechanics, where students learn how photosynthesis helps restore balance to Earth’s atmosphere. Set on a polluted planet, players use alien plants to fight clouds of carbon dioxide. Through arcade-style gameplay, students collect key resources such as carbon dioxide, water, and sunlight, which are later used in interactive drag-and-drop activities to generate photosynthesis. Each level combines action, experimentation, and reflection, ending with a short question to reinforce understanding. As difficulty increases, students explore how plants transform light energy into chemical energy, produce oxygen, and support life on Earth. Plants vs CO₂ is ideal for introducing and reinforcing life science concepts in an engaging and age-appropriate way.

Instructions

Play through this interactive game to learn about Photosynthesis. Suitable for Grade 6, Grade 7, Grade 8.

Main Concepts

Photosynthesizing organisms are the foundation of virtually all food webs.

Chlorophyll is a chemical compound in chloroplasts that can absorb light energy.

Photosynthesis affects Earth's atmosphere and oceans by removing carbon dioxide and producing oxygen.

Chemical reactions can transform energy within living organisms.

Plant cells have chloroplasts that aid in photosynthesis.

The material reactants in photosynthesis include water and carbon dioxide.

The function of photosynthesis is to make food for a plant to live and grow.

In photosynthesis, radiant energy from the sun is transformed into chemical energy.

The products of photosynthesis are oxygen and sugar.

The primary source of energy on Earth's surface is sunlight.

Discussion Questions

Before the Game

What is pollution? What molecule is building up in our atmosphere and causing problems for Earth? What organisms do photosynthesis?

After the Game

What is the goal of photosynthesis? What positive effect does photosynthesis have on the planet? What are the reactants needed for a plant to do photosynthesis? Where in a plant cell does photosynthesis take place? What are the products of photosynthesis?
