Turn an environmental problem into a testable idea
Choose a project, read the build guide, change the controls in its live model, and compare the result with your real experiment. The simulations show patterns for learning. Real results will vary with materials, weather, location, and measurement methods.
Safe science first
Ask an adult or teacher to supervise cutting, hot water, outdoor collection, and electrical parts. Never taste project materials. Never release dirty test water, oil, plastic pieces, or chemicals into nature. Use clean cooking oil and paper pieces for model tests.
Solar Oven
Explore how sunlight, reflector position, and insulation change the heating power of a simple box oven.
Build it
Question: Which design warms the inside fastest?
Materials: A cardboard box, dark paper, clear food safe cover, foil, tape, and a thermometer.
- Line the box base with dark paper.
- Add a foil covered flap to reflect sunlight inside.
- Cover the opening with a clear layer and place the thermometer inside.
- Record the temperature at equal time intervals.
Use this as a warming experiment only. An adult must supervise outdoor use and any warm materials.
Heat the solar oven
Goal: warm the model above fifty five C.
Mini Wind Turbine
Test how wind strength, blade count, and blade angle affect a small model turbine.
Build it
Question: Which blade design spins steadily in moving air?
Materials: Reused card, a wooden stick, a pin, a bottle cap, tape, and a small fan.
- Cut equal blades from reused card.
- Attach them evenly around the cap.
- Mount the rotor so it turns freely.
- Use the same fan setting for every blade test.
Keep fingers, hair, and loose clothing away from spinning blades. Ask an adult to handle sharp tools.
Power the eco lights
Goal: light all three model lamps.
Layered Water Filter Model
Compare how gravel, sand, cloth, and activated carbon change the appearance of model dirty water.
Build it
Question: Which layer order removes the most visible particles?
Materials: A clear reused bottle, clean gravel, clean sand, cloth, activated carbon, and muddy model water.
- Ask an adult to prepare the bottle safely.
- Place cloth near the outlet, then add test layers.
- Pour the same amount of model dirty water through each design.
- Compare colour, visible particles, and flow time.
Filtered project water is not safe to drink. Dispose of it responsibly and wash hands after the activity.
Build a filter stack
Goal: produce a clear looking sample with steady flow.
Rainwater Collection Model
Discover how roof area, rainfall, and tank size affect how much rainwater a simple system can store.
Build it
Question: How does collection area change the amount stored?
Materials: Card, a tray, a clean bottle, a straw, tape, a measuring cup, and clean water.
- Shape the card into a sloping model roof.
- Guide runoff through the straw into a bottle.
- Pour equal amounts of water over different roof areas.
- Measure the collected water and record any loss.
Stored rainwater may contain germs and pollutants. Do not drink it without approved treatment.
Fill the rain tank
Goal: store useful water without overflowing the tank.
Compost in a Jar
Model how the balance of fresh scraps, dry leaves, air, and moisture changes decomposition.
Build it
Question: Which mixture breaks down without becoming too wet or smelly?
Materials: A clear container with air holes, dry leaves, a little soil, fruit or vegetable scraps, and water.
- Add alternating thin layers of dry and fresh material.
- Keep the mixture damp, not soaked.
- Allow air to enter and mix the contents regularly.
- Observe colour, texture, smell, and volume over time.
Use plant scraps only. Wear gloves, avoid mouldy material, and wash hands after handling compost.
Balance the compost jar
Goal: create a warm, earthy, balanced model.
Model Oil Spill Cleanup
Compare containment, absorption, and surface removal in a safe tray model using clean cooking oil.
Build it
Question: Which cleanup method removes the most oil while taking the least water?
Materials: A shallow tray, water, a small amount of cooking oil, cotton, card strips, a spoon, and paper pieces.
- Add water to the tray and place a little cooking oil on the surface.
- Test a card barrier, cotton pad, and spoon separately.
- Measure oil removed and water accidentally collected.
- Seal all used material in household waste.
Never use motor oil or test in a natural water body. Keep all model oil contained.
Clean the model bay
Goal: click and clean all eight patches.
Mini Greenhouse
Investigate how light, ventilation, and water influence the conditions around a young plant.
Build it
Question: Does a clear cover change air temperature and soil moisture?
Materials: Two matching clear containers, soil, fast growing seeds, water, and a thermometer.
- Plant the same type and number of seeds in both containers.
- Cover one container and leave the other open.
- Give both the same light and water.
- Measure temperature, moisture, and growth daily.
Provide air holes and avoid overheating living plants. Reuse or recycle containers when the experiment ends.
Grow a healthy seedling
Goal: reach seven healthy leaves.
Reused Bottle Hydroponic Model
Explore how light, nutrient balance, and air near the roots affect a water grown plant.
Build it
Question: What balance supports steady root and leaf growth?
Materials: A clean reused bottle, a plant cutting or suitable seedling, cotton, water, and a school safe plant nutrient solution.
- Ask an adult to prepare the bottle opening.
- Support the plant so only the roots reach the solution.
- Keep the water level below the stem and allow air around roots.
- Observe root colour, water level, and new leaves.
Use only labelled plant nutrients with adult supervision. Do not taste the plant or solution.
Manage the root zone
Goal: grow strong white roots and eight leaves.
Ocean Acidification Indicator Model
Use a colour indicator model to explore how more dissolved carbon dioxide can change water chemistry and affect shells.
Build it
Question: How does added carbon dioxide change the colour of a safe indicator?
Materials: Clear cups, water, red cabbage indicator prepared by an adult, straws, and cleaned shell fragments for observation.
- Add the same amount of indicator to two cups.
- Keep one cup as a comparison sample.
- With adult guidance, gently blow through a straw into the second cup without drinking.
- Compare the colours and record the change.
Do not drink indicator water. Use cleaned empty shells only and avoid collecting living organisms.
Protect the shell habitat
Goal: keep the indicator in the safer colour zone.
Stream Microplastic Trap Model
Test how mesh size, water flow, and cleaning frequency affect a model trap for floating paper particles.
Build it
Question: Which screen captures small pieces without blocking the water?
Materials: A tray, water, paper confetti, reused mesh or cloth samples, cups, and a timer.
- Place one mesh sample across a model channel.
- Release the same amount of water and paper pieces each time.
- Count trapped and escaped pieces.
- Record how often the screen needs cleaning.
Use paper pieces, not real microplastics. Collect every piece after testing and never release it outdoors.
Keep the stream flowing
Goal: capture most particles without blocking the stream.

Questions about environmental science projects
Which environmental science project is easiest for beginners?
The rainwater collection model and wind turbine are good starting points because the result is easy to see and the materials can often be reused.
Can these projects be used anywhere in the world?
Yes. Choose locally available safe materials and adapt the investigation to your climate, water access, school rules, and waste collection system.
Are the live simulations exact predictions?
No. They are learning models that show likely patterns. Real results depend on materials, weather, construction quality, and measurement methods.
Is water from the filter project safe to drink?
No. The project only demonstrates removal of visible particles. It does not prove that germs, chemicals, or other hazards have been removed.
How can students make the project scientifically fair?
Change one main factor at a time, keep other conditions as similar as possible, repeat each test, measure carefully, and record every result.
