One of my favorite things to explore with my students is preschool science. Doing preschool science experiments during circle time is a fun way to engage your students but you really need a science center or science corner in your preschool classroom for your students to explore science independently without an adult directing their learning. Children need time to manipulate and dive into science without us telling them the who, what, when, where, and why. Let them ask and answer their own questions through exploration at the science center.
I made our science center with an old night table and started going about making and collecting things for our preschool science center. Here are the materials and activities that have been the biggest hits with my students so far this year. I have more ideas and some new supplies coming that I can’t wait to share soon. Until then, check out these science activities for 3-year-olds!
*Some of these activities we moved to the floor, or our table because our science table is small but they would work great in most preschool science centers. Some of the supplies have affiliate links so you can find the supplies easily on Amazon.
What Goes In A Preschool Science Center
Below you will find simple independent science activities for your preschool or kindergarten classroom.
Sorting Living and Non-Living Things
This science center activity was a hit with my daughter, it’s so simple but really important. Usually, when I introduce this idea I do it first as a circle time, so every child understands how to do it so that during free choice they can explore it independently having already been engaged in the activity in a group. I just found a great book called What’s Alive that I plan to use this activity in my class very soon.
Preschool Magnetic Exploration
Magnets are so much fun but in a class as young as mine with 2-3-year-olds you need to be cautious. Our science center is pictured with a store-bought magnetic exploration tray and two homemade magnetic discovery bottles.
Discovery Bottle #2 – Pom Poms, magnetic disks, and magnetic balls. Like the discovery bottle above they are both in plastic VOSS water bottles with the cap glued on. The children used the large blue magnet to manipulate the magnetic disks and balls inside the bottle.
Exploring A Sunflower – Preschool Science
I planted this sunflower so that I could do this in my science area. There is no huge agenda other than exploring. We used the tweezers to get seeds out, although the children figured out by “scratching” the seeds they would fly out at them. While they did that, I opened many of the seeds to let them taste the seeds as well. I love bringing nature inside, even though we go outside for a good chunk of time daily I can never get enough of interacting with nature.
Weighing Nature in The Science Center
This science activity was a huge hit, the kids loved the scale. I like using nature because it gives me one more chance to bring the natural world inside. They didn’t just weight the nature; they explored it too. This play scale was OK, but I just bought this balance one, which will be a lot more accurate and developmentally appropriate as my students gain the understanding of lighter and heavier.
The activity is simple; the students weigh the nature to see which is heavier. They also then added all the items on, tried to see if two rocks were equal to 2 pinecones and one rock… the exploration was in depth. I hope they enjoy it when we do it again with the new scale filled with flowers and soil later this month.
Exploring Habitats, Predators, and Prey
Bringing the outside world into a small classroom for very young children isn’t always easy. One of the more successful attempts at exploring, the larger world inside our class has been this Arctic Ice sensory bin. To see how I made it check this post out. How we played was just like we play with any sensory bin I will join in from time to time and listen to how they are playing. One of my students was very interested in what the polar bears ate. So we all learned about predators that day. There will always be wonderful chances to teach if you give your students the time to explore.

Backyard Critters Discovery Bottle & Bug Viewer
This was so easy to make and the way the children use this is wonderful. These are all animals you see or hear in our area, so the children are familiar with many of them, even at a young age. I did this early in the year and brought it back out multiple times. Recently the children have been using it in pairs and small groups with one child calling out the animal and another finding it in the discovery bottle. The big bug viewer goes along perfectly with the main activity to give children a choice in the center.
I took photos of all the animals with my phone, made a collage and printed it. Add the magnifying glasses and you are set!
Wings or No Wings-Sorting
We just explored this activity this past week, and if you follow me on Instagram, you might recognize this photo. Like the other sorting activity, this one was done first as a circle time whole group lesson and then put out for free choice in our science area the following class. The children debated about the ladybug because many have never seen one fly. Great thinking! This activity also led to counting each pile, sorting into small groups of the same bugs, and more.
Winter Discovery Bottle Science Activity
This was thrown together with a clipping from my Christmas tree, and some holly berries from a bouquet and my students loved it. It allowed them to play with the prickly needles and berries without me worrying and hovering about them getting poked ( those needles were so sharp, my arms were shredded after putting the lights on!) or possibly eating the berries. It was fun to turn this bottle upside down and watch the berries try to get around the pine needles to float. Also, the water magnified it all to inspect it that much easier.
Inside the bottle, it’s just the branch, berries, and plain water. The bottle remained clear and the plants bright for about two weeks; then it started to brown. We made similar ones with leaves for the fall which also stayed nice for about 2-3 weeks.
Freeing Toys From The Iceberg
This is such fun and what I would call classic activity for preschool, using pipettes with warm water the children free the toys from the ice. They learn that the ice will melt from the warm water and as it melts the toys come loose. I like doing this as a group because some kids just want to squirt the water and others will stay until everything is free. At free choice children have the chance to do that, engaged at their interest level!
Pumpkin Preschool Science Experiment – Physics!
Not all science at preschool happens in the science center. We did a pumpkin hunt outside in our playground in the fall. After the children had found one mini-pumpkin each some put them aside and played on our playground, but a few others started seeing if the pumpkins could roll down the slide. Oh heavens! I was so excited watching them explore, have races, and as the next photo shows they also tried to explain why the pumpkins that rolled off their sides didn’t move anymore. Science and play together!
