7 Fun Dinosaur Activities to do at Home

Dinosaurs seem to capture the imagination of every child at some point, and almost every kid I’ve known has gone through a dinosaur phase.  Some kids never grow out of it.  What better way to keep your kids active and  learning than with dinosaur activates you can do at home.

Here are a few of our favorites:

Grow Dinosaurs

You can usually find these little guys in the dollar stores or the cheap gifts section in the entrance of Target, so it’s an inexpensive dinosaur activity.  You can also get some of these guys in bulk at Amazon, which seems to be a cheaper option per dinosaur all around. These little dinosaurs could make great party favors , stocking stuffers, or giveaways.

The process is simple once you’ve got your dinosaur ready.  You’ll just need a container or bucket and some water. Once you’ve got everything together:

1. Fill your container with water
2. Drop in your dinosaur
3. Watch it grow! 

We left our dinos on the kitchen counter and checked them before heading off to school each morning, then again before bed over the course of several days.  They hadn’t done much the next morning or evening, but had noticeably growth the following morning.  By the suggested 72 hours or soaking time, they had grown quite a bit. 

After measuring and playing with our dinosaurs for a bit, we put them back in the water and let them sit for nearly a week.  They grew considerably, though not nearly the 600% that the packaging suggested.  Still, this is a fun exercise and can get your kids measuring, making observations, predictions, and gauging results over time. 

Here’s a quick chart we used to track the growth. It was a fun exercise to let the kids measure and observe the changes over time. They learned that creating a simple log allowed them to measure and compare progress, just like their growth chart on the wall.

Day	Time	Size & Observations
1	9AM	2 1/4 inches
2	7:30PM	2 3/4 inches
3	9AM	still 2 3/4 inches
3	7:30 PM	still 2 3/4 inches long, but much fatter
4	7:30 PM	3 1/2 inches
5	7PM	3 3/4 inches
7	7PM	They got HUGE! 4 3/4 inches

Once the dinosaurs are removed from the water, they dehydrate and slowly shrink.  I took about a week for these dinos to return to their original size. You can drop them in water again and repeat.

DIY Bath Bomb Dinosaur Eggs

Make some home made bath bombs with a twist.  Put your plastic dinosaurs inside and make some hatchable dinosaur eggs for bath time fun.

• Small Plastic Dinosaurs
• Mixing bowl or container
• 1/2 cup Baking Soda
• 1/4 Teaspoon Water
• 2 Tablespoons of Citric Acid*
• 2 Teaspoons Oil (We prefer coconut oil, because it’s solid at room temperatures which helps the bath bombs stay together. Olive oil or vegetable oil will work as well)
• Water Soluble Coloring (optional – Note: food coloring may stain your tub, or your child)
• Essential Oils if you want some fragrance (optional)
• Molds (optional)

*Citric Acid is the ingredient in this list most frequently not on hand, but it is easy to find online. It’s the citric acid that makes the bath bombs fizz. And what’s a dinosaur bath bomb without the fizz? You could also check in your local pharmacy or bulk foods section or your grocery store.

To form your bath bomb eggs, do the following:

1. In your mixing bowl, combine 1/2 cup Baking Soda and 1/4 Teaspoon of water.
2. Add a few drops of your coloring if you want colored eggs
3. Knead mixture until it’s a uniform consistency
4. Add 2 Tablespoons of Citric Acid (it will start fizzing a bit. The citric acid is reacting with the baking soda.)
5. Add the oil. If you’re using coconut oil like us, you may want to heat the oil briefly to get it into a liquid form. A quick zap in the microwave should do the trick.
6. Add 1 Teaspoon Coconut Oil and mix

You should have a fairly dry and flaky consistency.  It should stick together if you squeeze it in your hands.  If your mix is not clumping together, add a bit more oil.  Just a little at a time, you want to keep it dry. You can always add a more.  Too much oil, and you mixture will be more like a dough.

Our little scientists didn’t care for the scent of the mixture, so we added 1/4 teaspoon of vanilla extract at this point, and he was quite happy with that.

DO NOT add water at this point, as it’ll cause the bath bombs to fizz now, instead of when you drop them in the bath.

Once you’ve got some good clumping action, help your little paleontologist  pack the mixture around your little plastic dinosaurs into egg shapes (or whatever shapes you like.)  If you want a smoother, less lumpy shape, feel free to press the mixture into molds. Plastic Easter eggs or muffin pans can work well (lightly greased so you can get the bath bombs out in one piece.)

The only thing left to do is to wait until the eggs dry and harden, which should take about 10 to 12 hours.  We usually leave ours overnight, and try to wait a few days before using them.

Then, bathtime! Drop one in the bath and watch it fizz.

Dinosaur Ice Eggs

You’ve heard of the Ice Age?  What about Ice Eggs?  That’s what our little guy thought he heard when we first talked about the Ice Age, so we decided to go with it and make some “Dinosaur Ice Eggs.”

Well, okay – our first few were more like Ice Spheres rather than ice eggs, since we didn’t have any egg shaped containers to freeze the water in. We did however have this handy Death Star ice mold, which worked quite well.

Plastic Easter eggs may come in handy here, if you can fine ones large enough for your dinosaurs. If they do not have holes in them where you can get some water inside once the egg is sealed, you can use a drill or soldering iron to make a small hole to fill with water. Remember to not fill all the way, as water expands when freezing.

Pretend you and your kid are arctic explorers and find a dinosaur encased in ice!  Or a whole bunch of them.  How should you get them out? 

Let your little scientist brainstorm ideas.  Should you simply wait around for the ice to melt?  Or perhaps speed up the process with a hair dryer?  Maybe pour some hot water on the ice?  Chisel the dinosaur out?

Try out each idea and note the results.

We left one to thaw at room temperature, which took about 3 1/2 hours to melt. Another one went into a bowl of warm water, which took several minutes to thaw. Dumping boiling water on another ice egg freed our dinosaur immediately. Chipping away at the ice took time and effort, and made a mess with ice chips flying everywhere.

What was your child’s best idea for getting the dinosaurs out of the ice?

Dinosaur Dig STEM Activity

Kids often love digging in the dirt or discovering hidden surprises.  You can channel their curiosity and inner archeologist with a dinosaur activity designed to unearth hidden dinos.

If you want a quick dinosaur dig activity, there are pre made kits like this one on Amazon that has everything needed.

A backyard sandbox is great in the summertime, or just a small tub of play sand where you can bury them for your budding archeologist to dig up. We all know that sand can get everywhere, and if the though of vacuuming up buckets of sand gives you pause, let’s look at another option for a dinosaur activity digging material.

You can make some simple ‘clay’ with just a few simple ingredients:

• 2 Cups Cornstarch
• 1 Cup water
• Shallow baking pan

It’s easy to mix any quantity you want with a simple 2:1 ratio of cornstarch to water. If your mix is too dry, add a bit more water, if it’s too soupy, add a bit more cornstarch. You get the idea.

For a more authentic “dirt” look, try mixing in some coffee grounds.

Drop a few of your dinosaurs in the pan and cover with the mixture. You may want to partially push in a dinosaur or two from the top, to give the appearance that a fossil is poking up from the ground waiting to be discovered.

Now, it’s a matter of waiting until it’s dry, which may take a day or two. Bonus if you can put them outside in the sun for a bit. In the wintertime, we’ve put them on top of our furnace to help dry quicker. You’ll know when the surface starts to crack, it’s digging time!

We used some clay sculpting tools and a paintbrush to dig up our fossils. You could just as easily use a spoon and an old toothbrush. We carefully dug around each of our dinosaurs and extracted them, then brushed them off.

One cool thing about the cornstarch “clay” mixture: when it drys out, you can just add another cup of water to make the goop again. You can set up another dinosaur dig, or just play!

Lego Dino

Sure, there a plenty of Lego dinosaur kits you can buy off the shelf (this one looks particularly cool), but sometimes it’s a fun challenge to just try to create from scratch. 

If you have Legos around the house, see what kind of dinosaurs your child can create with what they have.

Long necked brontosaurs or a giant T-Rex? Perhaps something a bit smaller like a velociraptor? Let your Legos and imagination guide you.
