1-2 years old

Give toddlers cool science gadgets that are no- or low-tech especially in their first two years. Granted, kids will eventually be more exposed to technology and electronics as they grow older. But this is an opportunity to introduce them to a world of simplicity.

Here are cool science gadgets you can buy for your 1-2 year old toddlers!


Fisher-Price Baby's First Blocks and Rock-a-Stack Gift Set

It comes with 2 science toys for kids in one set: 

  • The first is for matching shapes into the correct holes. A perfect opportunity to aid toddlers in sorting objects.

  • The second is for stacking varying-sized rings into a pole. This helps in training kids’ coordination and may be an avenue to teach them about sizes, colors, and numbers.


Hape Wood Building Blocks 

Fostering toddler imagination through scientific toys helps in cultivating their creativity. Hape Wood Building Blocks allow children to create their own designs and tap into their engineering ingenuity.

But even the more complicated irregular polygons, to stimulate toddlers’ analytical thinking and fine motor skills even further!


2-3 years old

It is advisable to, as much as possible, keep children off the screen at this age. They can be exposed to some educational shows, but only briefly. You should keep in check their recommended screentime to be certain. Since most kids this age play all day, scientific toys that require screens might not be the best option. Nevertheless, here are screen-less and cool science gadgets that you can buy toddlers ages 2-3:


Melissa & Doug Geometric Stacker 

From stacking unevenly sized rings into a pole, this upgrade trains toddlers to stack various geometrical shapes instead! Geometric Stacker from Melissa & Doug helps in further developing the critical-thinking skills of toddlers. 

It comes with three poles and three sets of rings. Kids can mix and match or perform the whole puzzle until they complete it. Guide them in their quest! Science toys for kids are meant to also initiate bonding time with children.


Mega Bloks First Builders

Lego is a golden standard among science toys for kids. And if you desire a similar experience, minus the choking hazard, then Mega Bloks First Builders might be the one for you!

This helps children refine their spatial reasoning skills, aside from improving their fine motor skills!


Quercetti Saxoflute 

Perhaps one of the most ingenious toys for the 3-4 year old toddlers category. Quercetti Saxoflute capitalizes on two of the things kids love doing the most: tinkering with stuff and making noise.

This flute set comes in 16 separate pieces. All of which can be interconnected to form one long Saxoflute. How they make the connections influence the sound it produces! Toddlers are not only limited by the number of connections they make, but also the angles! This develops their creativity further and their artsy side better.

Nothing beats playing a song made out of their own creation!


3-4 years old

As kids mature further, it is good to slowly reel them into electronics and more challenging scientific toys. These sets of cool science gadgets are still off the screen. But these are major upgrades from simple motor skills and dexterity fine-tuning. Toddlers can now analyze things better and this skill must be stimulated through the following science toys for kids!

4-5 years old

Brief exposures to screen time at this age would be fine. Especially those screen exposures that sharpen and mold their minds even further.
