Flying cupids, launching hearts, and so much more! Let’s kick off the season with a 14 Valentines Day STEM challenges  countdown. Valentines Day STEM activities are simple twists on everyday STEM activities. Adding hearts, traditional holiday colors, or themed candies/supplies is great for young kids. Encourage a love of learning with holiday themed STEM activities.

14 DAYS OF VALENTINES DAY STEM ACTIVITIES COUNTDOWN

Bring STEM fun to your Valentine’s Day this year! It’s super easy to give classic STEM activities a holiday makeover when you add theme accessories and of course traditional colors. This season we have been all over setting up fun and easy to do Valentines Day 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.

MY LATEST VIDEOS

Amazingly, STEM activities 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.

WHY VALENTINES DAY STEM ACTIVITIES?

You can keep STEM activities fresh all year long by adding fun themes along the way. Adding theme colors and accessories just allows your kids to practice the basic concepts one more time but with a little twist. I have always found that kids love these little twists.

We do love holidays around here, and if you are into them too, these Valentines Day STEM activities will be a big hit. One day my son may not care about themed activities as much, so I am going to enjoy these days while I have them.

Below you will find a mix of classic experiments, activities, and challenges that have been recreated with a Valentine’s Day theme.

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 ideas. Move the calendar around to suit your needs. Pick just a few 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.
