What Is A Discovery Bottle?
Discovery bottles, or sensory bottles, are great for kids to explore and discover. They are also easy to make and easy to use.
You can adapt or adjust the ingredients for whatever you have or hand. Or for whatever theme or concept you want to emphasize.

More Discovery Bottles Ideas To Use In Your Classroom
Discovery bottles can be used throughout the year in your classroom. They can be used to create wonder. Encourage conversation. Build vocabulary. Develop visual skills. And they are great fun!
I like to use baby soda bottles to create my discovery bottles. A baby soda bottle looks like a test tube and has a lid like a regular soda bottle.
You can use these great discovery bottles in your science center for observation or put them in your calm down center (or safe spot) for calming. Many of these bottles also work great on a light table.
You can also make distant concepts that might otherwise be out of their reach, like outer space, fit literally in their little hands. These Star Gazing Discovery Bottles let my toddler and preschooler explore stars, star formations, and inspired lots of awe as well.
More Valentine’s Day Ideas
There are so many activities that you can incorporate into your classroom for Valentine’s Day! You can incorporate the holiday into your math activity literacy activity or use books to celebrate Valentine’s Day!
A light table activity is also a great way to center the lesson around Valentine’s Day. When your kids are picking up and manipulating the plastic hearts on the light table they’ll be engaging in sensory play. They will also be developing those important fine motor skills too!
And no preschool Valentine’s Day theme would be complete without a Valentine play dough activity. Playing with play dough is a great way for kids to practice their fine motor skills. In a fun, hands-on way! The simple act of pressing chenille stems, beads, cookie cutters into dough has so many benefits for young children.
Your pre-K or kindergarten students could also work on their sight words during the holiday as well. Using Valentine card sight words is a highly engaging and fun activity can help your pre-k or kindergarten students get even more excited to practice their sight words.
You could also incorporate songs into the holiday. You can sing Valentine songs during circle time, transitions, or whenever your kids just need to refocus and get their wiggles out!

Thanks so much for including our glitter heart jars. The kiddos are making more for our discovery center next week!
