In 2015, I began doing homeschool pre-k lessons with my son. I would put together little thematic lesson plans that we would do together one morning per week. Each lesson would usually incorporate art activities, sensory activities, books related to the topic, a play activity, and writing. I mixed these up with the occasional music component, educational video, a trip to a related museum, or nature adventure.

In late 2016, I decided to broach the topic of environmental issues and pollution. Even though he was only 3, I thought my son would get something out of it, and in retrospect, he did! So I thought I’d share some of the activities we did. Feel free to use or share any of these ideas!

Oil Spills

My son still recalls the activity where we put toy animals into blue water polluted by an oil spill. I was inspired by a blog post where they used feathers in their experiment.¹ I added toy animals and showed how oil in the water stayed on the animals. Here’s what we did:

We started with plain blue water to represent the ocean.

Next, I mixed cocoa powder with vegetable oil, as recommended by Almost Unschoolers. We started with feathers but then I quickly realized that he’d love playing with his toy animals even more.

We added a few more animals as we continued to play and experiment. He observed several times that the oil wouldn’t simply rinse off the animals or his hands.

My son had so much fun that he asked me to do it again several months later!

Recycling & Composting

Recycling sticker game from the Dollar Tree. I bought a sticker set from Dollar Tree which included four disposal cans with stickers. The cans represented plastic, paper, aluminum, and compost. My son took the stickers and placed them on the appropriate can and he only needed a little help. It was a fun activity to do together! You can find similar games or activities online.

Pollution Jar

The last activity we did was to create a pollution jar. I got the idea from Pinterest but cannot credit the blog because it no longer exists. I asked my son to help me choose pieces of trash of various types of materials. We chose different types of plastics, paper, string, etc. We did not use any food waste.

Then we filled the jar with tap water and put the lid on.

We kept this jar for over a year. Over time the materials did not break down, especially the plastics. While that may be obvious to an adult, this was new and interesting information for a preschooler. He thought it was cool. I will say that when I disposed of it, the smell of chemicals from that jar was disturbing.

Other Ideas

We took a walk along the Tennessee River for that lesson as well, just to notice our surroundings. What sounds did we hear? What animals did we see? Did we notice any litter along the river? We talked about how the rivers and oceans are connected; that oceans are full of life; that water and air are our most precious resources. Even if a young child doesn’t understand everything you’re explaining, know that they are absorbing some of it and admiring your knowledge.

There is a coalition of aquariums across the United States that are striving to reduce the use of plastic straws. The coalition is called the Aquarium Conservation Partnership (ACP) and is a collaboration of 22 public aquariums in 17 states, including the Tennessee Aquarium. They are “committed to advancing conservation of the world’s ocean, lakes, and rivers through consumer engagement, business leadership and policy changes.”¹

Aquariums are awesome and full of wonder and thousands of children go through them daily. So they are poised to be leaders in positive change, and this is a great example of that! One of the things they’re doing is asking restaurants and others in the hospitality industry to reduce the use of straws by only giving them out upon request, instead of automatically. They’re also asking individuals to sign a pledge to stop using plastic straws.

What’s wrong with plastic straws?

First, the sheer amount of them! Just like with all single-use disposable plastic products, it’s the over-consumption of them. Think 500 million plastic straws per day. That’s more than one straw per person per day in the United States. Our consumption has gone way overboard and has created a waste stream that is too large for us to keep up with! Second, they are not recyclable at all.

Don’t feel guilty about having used plastic straws. Just please refuse plastic straws – START TODAY. Politely refuse those plastic straws – if everyone refuses just one straw per day, we’ll more than cut our usage in half!

I threw my disposables into the trash/recycling receptacle like I’m supposed to, how are they ending up in the rivers and ocean?

One of the critical issues with all the media about single-use disposable plastics is that the biggest question is often not answered: How does the plastic end up in the ocean in the first place?

Most people assume that once they’ve placed their disposables into a receptacle, those disposables go to the proper facility. What people don’t know is that many items don’t make it to the recycling facility or landfill. Since that’s out of our control, it seems impossible to do anything about it. But it’s not impossible by any means. The best way to guarantee that your single-use disposable plastics don’t end up in the ocean is…

To just not use them! Refuse them. Find an alternative. Then you do have control. We have the power to be the change.

So back to the question – how are plastics ending up in the rivers and ocean?

There are so many causes! Spillage from recycling that has been transported across the ocean for years to Asia; plastic products shipped across the ocean to the U.S. have spilled from ships; the fishing industry regularly dumps their trash into the ocean; trash and litter get blown or washed into storm drains and rivers that then feed into the ocean; illegal dumping; beach trash; river pollution; microbeads washing down drains; and debris from natural disasters and floods. Plastic bags are picked up by the wind and blown into waterways that flow into the ocean.

Ok, so what steps can I take?

First, let’s support the Aquarium Conservation Partnership. You can do this by signing the pledge (linked under Additional Resources below).

Second, refuse. Just say no thank you. To all single-use disposable plastics. Because recycling is not the answer. Only about 9% of our plastics get recycled. That means 91% is not recycled!

Third, if you must have something commonly produced as a single-use disposable plastic, like a straw, please buy a reusable one. Paper disposables and supposedly biodegradable straws are a better option, but it’s still going to be thrown away after one use. Try a stainless steel straw, glass straw, or bamboo straw.

Fourth, tell others! Tell your friends, your co-workers, your favorite restaurant, the local coffee shop, and your local school. So many to tell!

Fifth, participate in trash clean-up efforts. Join the Litterati. Maybe you’ll keep some of the trash you pick up from entering the ocean.

Last, stop supporting businesses that just won’t get on board. If consumers are asking businesses they patronize to stop using certain items, such as single-use disposable plastics, the consumer also has the power to not patronize that business. If consumers refuse to spend money at a business because that business does not do or provide what consumers want, then that business will be forced to change if they want to maintain profitability.

Final Thoughts

Collectively, have the power to create change just by modeling the best behavior. Refuse that straw. Be polite, of course. But just say no. You might influence someone else to refuse straws too. If everyone starts refusing straws, businesses won’t have the need to order as many. Then the plastic straw manufacturers will have to produce less. And then less will end up in landfills, in nature, and in the oceans. Carry a reusable stainless steel straw with you. Be the change! And as always, thanks for reading.
