Top 10 Environment Science Project Ideas for Class 6-8th

With over 7.5 billion of us on Earth, our combined actions also significantly impact the environment. As long as we are aware of the impact, we can do things as individuals, and work together as groups, to lessen the detrimental impact of billions of people. Explore important topics like air quality, water quality, the effects of climate change, and many others to make informed decisions about caring for our planet.

Top 10 environment science project Ideas for Class 6-8th

1. The Effect of Oil Spills on Underwater Plant Life

The Effect of Oil Spills on Underwater Plant LifeThe BP oil spill will have consequences for decades to come. This timely science project could focus on the long-term impact on animals that feed off the plants or only the effects on the plants themselves.

2. An Investigation into Methods Data Storage Using Magnets

An Investigation into Methods Data Storage Using MagnetsThere are several ways to store data in a computer system. CD-ROMs use the interference patterns created by light waves, but hard-drives tend to use magnetic platters. This science project would likely appeal to a techie high school student who wants to understand how computers work.

3. Analysing the Reactivity of Alkali Metals in Water

Analysing the Reactivity of Alkali Metals in WaterAn oldie, but also a classic. Metals in group one of the periodic table all have increasingly violent reactions to water. This project makes a good demonstration to get kids hooked on chemistry, although it’s advisable to avoid using Cesium. You could talk speculatively about the possible reaction francium, a scarce alkali metal, would display for a science fair project.

4. Demonstrating Conservation of Matter

Demonstrating Conservation of MatterThe Law of Conservation of Matter states that no matter can be created or destroyed, merely changed in form. This can, however, be hard to comprehend. A cost-free science project could focus on showing exactly how this is the case for a certain reaction.

5. Electromagnetic Railguns – Theory and Practice

Electromagnetic Railguns – Theory and PracticeThe US army has a prototype railgun that can fire a 3kg projectile at almost seven times the sound speed. That snippet of information alone should be enough to get almost any high school boy excited, regardless of whether or not he normally enjoys science. If you want a particularly involving project, you could even try to build a railgun of your own, albeit a considerably less powerful one.

6. Making a natural pH indicator

Making a natural pH indicator

Boil cabbage in a covered pan for 30 minutes or microwave for 10 minutes. (Don’t let the water boil away. Let cool before removing the cabbage. Pour about 1/4 cup of cabbage juice into each cup. Add 1/2 teaspoon ammonia or baking soda to one cup and stir with a clean spoon. Add 1/2 teaspoon vinegar to the second cup, stir with a clean spoon. Add about 1 teaspoon clear non-cola to the last cup and stir with a clean spoon. After answering the first two questions for this experiment, pour the vinegar cup contents into the ammonia cup.

7. Measuring pH of soil


Pick two or three different soil locations, such as a garden, wooded area, city park, or meadow. Write down as much as you can about what you find. Dig down about 2 inches, scoop out 2 cups of soil, and seal it in a plastic bag for later use. Label each plastic bag. Be sure to clean your digging tool after collecting soil samples at each location. Measure the pH of each soil sample following the directions provided in the garden soil pH test kit and record each soil sample’s approximate pH.- Save the excess soil from each site for use in the “Soil Buffering” experiment.

8. Renewable Energy

Paint the inside of one of the Styrofoam cups with black poster paint. Add the food to the bottom of the cup. Chop it into small pieces. Cover the cup with cling wrap, and pull it tight; hold it in place with an elastic band around the cup’s rim. Use the aluminum foil to collect sunlight. Please make sure the shiny side is up, and try to avoid getting any wrinkles in it. Then wrap it around your cup so that the foil faces inwards and fasten with tape. Trim the top edge. Put this inside a second cup, hold the tube securely in place, and provide a little more insulation for your oven. Now put your ‘oven’ into an insulator. Make sure the collector foil is unwrinkled and pointing at the sun.

9. Solar Car

Solar CarCut a 2-inch-wide strip of wood. Mark axles by drawing two lines and mark two points around 6 mm away from each side. Each screw will hold the axles, so insert one eye screw in each of the issues. Insert axle and ensure the alignment is straight and can spin freely. Later use a piece of straw and place them as a spacer on both sides. After making space for the wheels, now insert wheels on all four sides. If your rear wheels are plain, you need to insert a gear or a pulley next to the rear wheel. Now, insert a small pulley or a gear onto the shaft of the DC motor. Now place the motor on the mount and strap it securely. Place it on the motor mount on the car, ensure the gears, one on the wheel and another on the shaft, are engaged. Place the solar panel on the car and connect all the required wires to the motor. Note that the solar cell panel is placed slanted. Finally, take your solar car to a sunny location and test it!

10. Gauss Rifle

Gauss RiflePlace the first magnet on the wooden ruler at the 2.5-inch mark. If you are not using the ruler, you need to measure the distance and place the magnet at the marked point. Tape the ruler temporally on the table so that magnets don’t jump and attach. Keep four magnets on the ruler with a 2.5-inch distance between each of them. On the right-hand side of each magnet, place two steel balls. Make sure the ball doesn’t roll down from the ruler. Now, it’s time to fire! Set the steel ball on the left-most magnet and push-roll to the magnet. When the gauss rifle fires, the ball on the right shoots away from the gun and hits the target with sustainable force.
