Help kids learn about the impact of pollution and the importance of protecting our earth and environment with this pollution experiment for kids. This simple acid rain experiment is great for preschool, pre-k, kindergarten, first grade, 2nd grade, 3rd grde, 4th grade, 5th grade, and 6th graders. All you need are a few simple supplies ot try this flower experiment where children can see first hand the impace of acid rain on plants.Use this water pollution experiment for kids as part of earth day science or earth science experiment.
Pollution Experiment for Kids
This acid rain experiment allows children to abserve the impact acid rain has on the growth, foliage, and health of plants. This simple water pollution experiment for kids is a quick and easy way to observe the impact acid rain has on the enviroment around it. Use this flower experiment as part of a unit of environment, pollution for kids, earth day science, plant activity for kindegarteners, preschoolers, grade 1, grade 2, grade 3, grade 4, grade, 5, and grade 6 students.
Acid Rain Experiment
Pollution is a problem in our world. We pollute the water and ground by litering paper, plastic, glass, and other garbage on the ground or into the water. Pouring chemicals such as motor oil and gas into water or runoff from weed killers used on our lawn make their way into our water and must be filtered. Factories, homes and cars pollute the air by burning coal, gas, and other chemicals. The smoke travels through the air and into the atmosphere where it gets trapped in the clouds with the moisture that naturally evaporats from the earth’s surface. When clouds get full of water, they empty by raining (or snowing) bringing the pollution along ; this is called acid rain. Not all rain is acid rain. Acid rain is the rain that has a high ph level (acid level).
So, what’s the big deal – that’s the Earth’s way to filter and provide water, right? Well the problem is that when we produce too much pollution that rains down and becomes part of the water source for plants – the acid rain can harm plants (and animals in high enough concentrations). Normal rain has a PH of 5.6. At 4.3 acid rain starts to have harmful effects headaches, coughs, and throat irritations in humans. Fish will begin to die at a ph of 4.2. When people eat toxic plants and animals that have been contaminated with acid, they can have kidney problems, brain damage, and more.
All you need to try this quick acid rain experiment on plants are a few simple materials you may even have on hand already!
- 3 jars
- white distilled vinegar OR lemon juice
- 3 single flowers (carnations, gerberra daisy, etc)
Water Pollution Experiment for Kids
Start by labeling your 3 jars and adding the solution indicated:
- water (just water)
- little acid rain (1/4 cup vinegar OR lemon juice and the rest water)
- lot of acid rain (1 cup vinegar OR lemon juice and the rest water.
Add a flower to each solution. Point out how all the flowers are healthy and look about the same. You can add a cute green constrution paper grass border like we did, but it is purely for asthetics!
Acid Rain Science Project
Observe the flowers. DO you notice a difference in the flowers. Document the changes you observe in the flowers on the worksheet below.
Acid Rain Experiment on Plants
So what happened? Basically, the lemon juice or vinegar is highly acidic; it contains a lot of acid just like acid rain. The acidic solution was soaked up by the plant along with the water—just like pollution in rain and groundwater is soaked up by plants. Acid is not good for the plants and it interrupts plants ability to make the glucose they need to grow and have energy. Their growth will be stunted at first and then they will look withered if the pollution continues.
Acid Rain Science Experiments
After students have recorded their findings on the worksheet discuss what they observed.
- Which flower looks the best?
- Why do you think that flower looks better than the other flowers?
- What does this tell you about the importance of taking good care of our environment?
- What are some things you can do to help cut down on pollution?
- What will happen if you put the polluted flower into a clean water solution?
