Are you ready to get your hands dirty with some ooey, gooey, slimy fun? I’ve got just the thing for you – afterschool slime activities that’ll keep the kids entertained for hours.

Slime is not just a fun substance, it also provides a sensory experience that can ignite creativity and curiosity. Additionally, it offers a fun way to teach basic science concepts without children realizing they are learning. Shh, don’t tell them that part!

Let’s dive into the world of afterschool slime activities by rolling up our sleeves, and grabbing some glue and activator. Trust me, once you see the joy on those little faces as they squish and stretch their slimy creations, you’ll be hooked too.

Benefits of Afterschool Slime Activities for Kids

When you hand a container of slime to your children, they are apt to dive in and start experiencing the substance’s interesting properties with their hands and senses.

Sensory Exploration

Slime is the ultimate messy play material, offering a fun time for kids. Kids can’t resist squishing, stretching, and manipulating it. 

This exploration helps develop their sense of touch and builds neural connections in the brain. Plus, the cool, gooey texture is just plain fun.

Fine Motor Skill Development

All that squeezing and stretching is secretly building strength in those little hands and fingers. The resistance of the slime provides a gentle workout. Pinching, pulling, and shaping slime hones fine motor skills needed for tasks like writing, buttoning, and using utensils.

Science Learning

Slime is a gateway to scientific curiosity. Making slime is an opportunity to explore states of matter and chemical reactions. 

Older children can delve into slime’s different properties and the science behind it. But even little ones absorb basic science concepts as they play.

Creativity and Imagination

Slime play has no rules or expectations. It invites open-ended creativity as kids mold, shape, and pretend. 

Slime is the perfect blank canvas for unstructured play. These are just a few of the benefits of afterschool slime activities. When kids have it in their eager hands, they’re learning more than they realize – and loving every minute.

Easy Slime Recipes for Afterschool Fun

Homemade slime has never been easier to make. With just a few ingredients, you can whip up a batch in no time. Here are some of our favorite foolproof recipes:

Basic Slime Recipe

This is the slime recipe I always start with. You’ll need:

  • 1/2 cup white school glue
  • 1/2 cup water
  • 1/2 tsp baking soda
  • 1-2 tbsp saline solution (must contain boric acid and sodium borate.)

Mix the glue and water in a bowl. Add the baking soda and mix. 

Then add the saline solution until the slime forms and pulls away from the sides of the bowl. Knead by hand until it reaches the perfect slime consistency.

Fluffy Slime

For a marshmallow-like texture, try this recipe:

  • 2/3 cup white school glue
  • 1/2 tsp baking soda
  • 1/4 cup water
  • 2-3 cups shaving cream
  • 1.5 tbsp contact lens solution

Mix the glue, baking soda, and water in a bowl. Add the shaving cream and mix until combined. Add the contact solution and mix until slime forms. 

Knead as needed. For see-through slime, use clear school glue instead of white in the basic recipe. You can add glitter, sequins, or small toys for a cool effect.

Glitter Slime

Add a generous shake of glitter to any slime recipe for instant sparkle. Fine glitter works best and won’t be abrasive on little hands.

Magnetic Slime

For a STEM twist, make your slime magnetic. Add 2 tbsp of iron oxide powder to your favorite slime recipe. Then play with it using strong neodymium magnets (with adult supervision). 

The variations are endless – have fun experimenting to find your perfect slime recipe. These DIY slimes beat store-bought any day.

Slime Ingredients and Materials

Half the fun of slime is experimenting with different ingredients and mix-ins. Stock up on these supplies and let the slime-making begin.

Glue Options

White school glue is the most common base, but clear school glue (sometimes called PVA glue) is great for transparent or jewel-toned slimes. You can even use glitter glue for a pre-sparkled base.

Slime Activators

The secret to slime success is the activator – the ingredient that turns glue into slime. My go-to’s are:

  • Contact lens solution (must contain boric acid and sodium borate)
  • Liquid starch

Always supervise kids when using these chemicals and have them wash their hands after play.

Add-ins for Texture and Color

Now for the fun part – the mix-ins. Some of our favorites:

  • Food coloring or liquid watercolors for vibrant hues
  • Glitter in every size and color
  • Foam beads for a squishy texture
  • Shaving cream for fluffy, stretchy slime
  • Baby oil for glossy shine and softness
  • Lotion for a creamy, spreadable consistency

Raid your craft stash and experiment with whatever you have on hand. 

Slime is a blast to play with, but sometimes things can go wrong. Maybe your slime is too sticky, or it’s dried out and lost its stretch. Don’t worry, I’ve been there. 

You can fix most slime snafus with a little know-how and some simple ingredients like baking soda and contact lens solution. 

If your slime is too sticky, it probably needs more activator. Try adding a little more contact lens solution or baking soda, a little at a time, until it reaches the perfect consistency. Knead it well after each addition. 

If it’s still too sticky, let it sit for a few minutes. This gives the activator time to work its magic.

Slime can dry out if it’s left out of its container or if it’s been around for a while. 

To revive it, try adding a little water or lotion. Knead it in thoroughly. If it’s still not stretchy enough, add a touch more. 

Be careful not to add too much, or you’ll end up with slime soup. To keep your slime fresh and stretchy, always store it in an airtight container. I like to use plastic containers with tight-fitting lids. 

Make sure your hands are clean and dry when you’re playing with slime, so no dirt or moisture gets trapped inside. With proper storage, homemade slime can last for weeks.

Themed Slime

Celebrate the seasons with themed slimes. For fall, try adding pumpkin spice or apple pie spice to your slime. 

In the winter, make a batch of sparkly “snow” slime with silver and blue glitter. 

Spring is perfect for pastel-colored slimes or even a “dirt” slime with cocoa powder and plastic bugs. 

And for summer, what about a tropical slime with a coconut scent and mini umbrella picks?

Kids love slimes that look like their favorite characters. You can make Minion slime with yellow coloring and googly eyes, or Elsa slime with blue and silver glitter. Superhero slimes are a hit too – try green for Hulk, red and blue for Spider-Man, or black and yellow for Batman. 

Bring the outdoors in with nature-inspired slimes. Make an “ocean” slime with blue coloring and plastic sea creatures. Or how about a “galaxy” slime with black glitter glue and star-shaped confetti? You could even make a “lava” slime with red and orange coloring and a cinnamon scent. 

Experimenting with Slime

Is slime a solid or a liquid? It’s actually a bit of both. 

Slime is a non-Newtonian fluid, which means it can act like a solid or a liquid depending on the force applied to it. When you stretch slime slowly, it flows like a liquid. But if you pull it apart quickly, it snaps like a solid. 

Experimenting with slime is a great way to demonstrate this unique property. Slime is just one example of a non-Newtonian fluid. Others include quicksand, ketchup, and even blood. 

These substances don’t follow Newton’s law of viscosity, which states that a fluid’s thickness (viscosity) should stay constant. Instead, their viscosity changes based on the force applied. 

Making slime is a basic chemical reaction. When you mix the glue (a polymer) with the activator (a cross-linker), it creates a new substance with different properties. 

Slime is an excellent hands-on activity that can be adapted for different ages and skill levels, making it perfect for afterschool programs. Additionally, it’s a fun way to reinforce science concepts learned in school.

Set up different slime stations with various ingredients and mix-ins. Kids can rotate through the stations, experimenting with different recipes and techniques. You can have a station for fluffy slime, another for clear slime, and another for glitter slime.

Have kids work in teams to create a giant batch of slime, or challenge them to create a slime with specific properties (e.g., the stretchiest, the fluffiest, the most colorful). You can also use slime for team-building activities like slime tug-of-war or slime relay races. The possibilities are endless.

Keep things exciting with weekly slime challenges. Challenge kids to create a slime using only certain ingredients, or to make a slime in a specific color scheme. You could even have a slime-making contest with prizes for the most creative, the best-textured, or the most unique slime.

Key Takeaway: 

Slime-making isn’t just fun; it’s a science lesson in disguise. From fixing sticky or dried-out slime to creating themed variations, there’s always something new to learn and explore. Incorporating slime into education teaches kids about non-Newtonian fluids and chemical reactions in an engaging way.
