14 DAYS OF VALENTINES DAY STEM ACTIVITIES
VALENTINE ACTIVITIES
Bring STEM fun to your Valentine’s Day this year! It’s super easy to give our STEM challenges a Valentine theme makeover with simple materials and everyday supplies. Set up fun and easy to do Valentine STEM activities and science experiments to get your kids thinking!
WHAT IS STEM?
STEM takes science and builds in elements of technology, engineering, math, and sometimes even art. A good STEM activity will include at least two of these four pillars such as math and engineering or science and technology.
Amazingly, a STEM activity is perfect for young kids because it provides so many valuable life lessons and skills such as observational skills, critical thinking skills, and design skills. It also provides a much-needed dose of failure before success. Perseverance and patience. Valentine STEM is also great for those kiddos who aren’t keen on crafts.

START WITH A TINKER TRAY!
Start each holiday or season with a theme tinker tray. Go to your local dollar store or seasonal aisle of any big box store for inexpensive finds to add to this type of tinker kit or tinker tray. Read more about what is on our tray here.
A tinker tray is just one of our go-to resources for inexpensive STEM activities supplies. If you want to learn more about how we do STEM on a budget, CLICK HERE.
VALENTINES DAY STEM SUPPLIES
Have fun with these STEM ideas below. Use them to set up your own 14 day countdown calendar or move them around to suit your needs. Pick just a few Valentine activities to enjoy or try each one! It’s up to you how many you try.
The materials are inexpensive overall. You may already have many simple supplies in your cupboards and drawers. The craft store, dollar store, and grocery store have everything you need. Some of the purchased materials can even be saved and reused for different activities. I like to store materials in a large plastic tote and separate holidays and seasons into zip-top bags to keep it organized.

The width of the mouth of the cup or so is fine. There is no specific measurement or you can use index cards.
