It started with a drawer. Then a cupboard and now overflow into my studio. They come in a variety of sizes, designs, colours and even quality. They don’t stack and store nicely. I will warn you about that, but if there is one thing you need to add to your arsenal of cool supplies to have on hand for science, STEM and crafting, it’s silicone molds.

Where to Buy Silicone Molds

You can find silicone molds everywhere. I order a lot of my special ones from Amazon, but I also pick up molds at the dollar store, grocers, crafting stores and kitchen supply shops. I’m always on the look out for unique and special molds.

Note, molds vary in quality and construction. Not all molds will work for all projects. For instance something with a lot of detail may not work well for making bath bombs, but is great for soaps. Some molds are thicker and stiffer construction making it harder to remove items, but also making them better for really packing in materials. They all have their uses. So I suggest collecting all of them!

Why Use Silicone Molds in Education

I can hear you asking, what the heck do you do with all of those silicone molds? Well, we take a regular old science experiment or activity, and make it something that will really WOW the kids!

No matter what your kids are into, I bet there is a silicone mold that will excite them. My most cherished mold is a Doctor Who TARDIS. Our Lego molds get so much use. The rest are fantastic when we are doing specific themes. Harry Potter, Spiderman, Christmas, Halloween, Pirates, Unicorns, Dinosaurs…. phew! The list is endless!

Can you see now why I feel silicone molds are so important for your educational toolkit? They get kids motivated, excited and interested.

And when do kids learn the most? What makes those lessons stick in their memories? When they are having fun, excited and thrilled with the experience.

So ramp up your learning and education with these innovative silicone mold ideas.

STEM Activities and Experiments Using Molds

FROZEN OOBLECK

We are obsessed with Oobleck around here! We have done so many experiments with it from making it glow, to having it magically change colours, to using it in an egg drop experiment. The amazing list of things you can do with Oobleck seems to be endless! One of our experiments was to see what would happen if we froze Oobleck. Now of course we could have just frozen it in a big blob, but that wouldn’t be any fun, so we froze it into cool and interesting shapes using our silicone molds!

MAKING PLASTIC

We love making bioplastics and whether you chose to make a milk plastic or a clear gelatin plastic, the best part is picking a silicone mold to shape your homemade plastic into something awesome!

DIY Bath Bombs

The chemistry and science behind bath bombs earns them a spot in the STEM section of our list. We love making bath bombs and discussing the amazing reactions behind the fizz. And when you make bath bombs in silicone molds you can get some really cool shapes and bath bombs that kids can have fun decorating.

Simple Erupting Chemistry

Kids love a good baking soda and vinegar reaction. They get really excited and when they get to erupt cool shaped stuff! By using silicone molds you can shape your baking soda paste into some amazing little creations that kids can then erupt. We did one project at Christmas time where we made our baking soda into Christmas trees that the kids decorated before we erupted them. It was such a fun and cool project. They still talk about it.

Paintball Bombs

My kids recently played paintball for the first time, so this project immediately caught my attention. I am fascinated by the science behind it and think it would make such an amazing summer STEAM project. Use silicone molds to help get a uniform shape to your paintball bombs. Get all the details from our friends at Teach Beside Me.

Care of Silicone Molds

If cared for properly, silicone molds can last 10 to 20 years with regular use. That’s a lot of educational projects! You could pass these on to future generations.

Preventing Cross Contamination

For safety reasons I always designate my molds for either food use or science use. Although I clean them regularly, it’s a safety thing. We may not get them completely clean, certain items may degrade the silicone, plus who knows! I just don’t want to take the risk.

To remember whether a silicone mold is for food or science/crafts, simply use a Sharpie and write on the bottom of them. It is very easy to keep track this way and it will ensure your silicone molds that are used for treats remain food safe.

Tip! Often I will start out using molds for food, then after a few uses move them into the science and craft pile.

Cleaning Silicone

To clean your silicone molds, simply use hot water (as hot as you can stand) and a grease cutting dish soap. Hand wash and dry. Let it sit on a drying rack for a few hours before putting it away to ensure it is dried completely.

Never use abrasive cleaners or sponges. This will damage your molds.

Don’t let your molds remain dirty. Letting the dirt sit in the molds will make them harder to clean.

If you are struggling to clean your molds or remove stains, use baking soda. Simply make a thick paste and apply it over the areas you are struggling to clean. Let it dry overnight and rinse in the morning.

I will also tell you something, if I am in a hurry, I often toss my silicone molds in the top rack of my dishwasher. It works most of the time, but I do find they often end up with a soapy residue. So often I end up spending more time cleaning that off, than if I had just done it by hand the first time!

Protecting Molds from Damage

Limit the use of oils in your molds as these can cause deterioration of the silicone. Also, keep out of direct sunlight, UV rays will also cause your silicone mold to deteriorate.

I find our molds are quite tough for the purposes we are using them for, but accidents do happen. If you do get a tear in a beloved mold that can’t be replaced you can repair them with a silicone rubber adhesive. Simply make sure all edges are well cleaned with acetone on the bonding edges before applying the adhesive.

Storage of Silicone Molds

It is recommended that silicone molds are stored flat. For my purposes I have had no problems at all with just stacking them in a drawer or cupboard, but I’m not working in a professional capacity with my molds. So if a few of my molds don’t sit completely flat after a year or two, I am really not worried about it. You may feel differently.

A NOTE ON TYPES OF MOLDS

Just a quick note about quality and construction of silicone molds. Once you start using them you will notice a lot of variability in the softness, stiffness, depth, detailing and more of molds. This will lend certain molds to different types of uses. For instance, when making bath bombs you want a mold with minimal detail and quite soft. But making soap can be done in a mold with more details and can be fairly stiff.

As you start using molds you will see how certain types work better for different projects. Soon you will be a master of silicone molds too!

So do I have you convinced that you need to add silicone molds to your educational toolbox? I know we love them here at STEAM Powered Family and I am sure they will add something special to your projects.
