One bag of Conversation Hearts can go along way to trying out some of these ideas.
CHALLENGE #1 Candy Building
Use your favorite heart shaped Valentine’s Day candy to stack towers, make bridges, or build structures. You can add cardboard pieces to make houses too!
CHALLENGE #2 Candy Stacking Races
Fun minute to minute. Have candy heart stacking races. Who can stack more hearts?
CHALLENGE #3 Candy Structures
Using a soft Valentine’s Day candy and toothpicks build structures, sculptures, 3D shapes, or anything you can imagine. You can see an example of the candy we used here!
CHALLENGE #4 Valentine’s Day Reactions
Valentine’s Day is all about chemistry! There are so many fun ways to explore baking soda science. You will need baking soda, vinegar, and red food coloring. Check out our Valentine’s Day chemistry ideas to see how to set up a love potion science activity.
Or you can do a simple reaction experiment in a plastic bottle or other container. I like to choose a container that tapers in towards the top. This way you can get a really nice eruption that kids love. Scoop in baking soda, color your vinegar red, and use a baster, measuring cup or eyedropper to add the vinegar to the baking soda.
CHALLENGE #5 Candy Dissolving Activity
How long does it take your favorite candy to dissolve in different liquids? Why does the candy dissolve? Where does the candy go once it is dissolved? So many great questions with an easy experiment.
Set up small cups with a variety of different liquids such as water, milk, cooking oil, seltzer, or juice. Add a favorite Valentine’s Day candy like conversation hearts to each cup.
Set a timer and record your results!
CHALLENGE #6 Secret Messages
Cut out white paper hearts and write secret messages in white crayon! Use watercolors or even water mixed with food coloring to read the messages. You can make your own conversation hearts! You can also try the lemon juice version, but you do need to add heat to the activity.
CHALLENGE #7 Build LEGO Hearts
CHALLENGE #8 Red Hots Oobleck
CHALLENGE #9 Build a Maze
Use LEGO bricks and base plate or a box top, straws, and tape to create a heart shaped marble maze!
CHALLENGE #10 Cardboard Hearts Building Challenge
Check out how we cut out cardboard hearts from the recycling bin and turned them into a building toy. Super easy and makes a great activity for quiet time too.
CHALLENGE #11 Spinner Toy or Thaumatrope
This is a really fun and simple science craft for kids. Make a thaumatrope with straws, paper, and markers. See how we made ours here.
CHALLENGE #12 Cupid’s Catapult
Build a catapult to launch candy hearts in the air. How far you launch them depends on your catapult design and the candy you choose! We have several building ideas for catapults to check out. You can even build several catapults and test them against each other or design a whole new one!
CHALLENGE #13 Valentine’s Slime
We love slime and have several cool Valentine’s Day themed slimes including a heart slime made with a clear glue or pink slime made with white glue.Our original slime recipe can be found here. You can add food coloring, glitter, heart confetti, or plastic hearts to our slime.
CHALLENGE #14 Love Bot
Build a recycled robot with a love bot theme! Raid your recycling bin to find interesting things to use. I also like to keep a bin to add neat things to that you might otherwise throw away. You can see what we keep on hand here for STEM on a budget.
CHALLENGE #15 BONUS
Learn about how your real heart works! Can you feel your heart beating. Learn how to check your pulse. Recheck your pulse after you have done jumping jacks or run around. Is it different? Maybe you have the chance to listen to your heart beat.
We need our hearts, so let’s take care of them. Plan a heart healthy snack to share when you work on these Valentines Day challenge cards.
You can print these at home in color or black and white. Cut out and laminate them if you plan on using them with a group. You can also print out a color copy at home and have a copy center print it on heavy weight paper!
Picka and choose the ones that work for you! Or write your own valentines Day challenge cards with your kids.
