Water Science Camp for Kids
This DIY summer camp at home explores scientific concepts like surface tension, absorption, solubility, and more using simple, kid-safe materials. Whether running a full-day camp or just filling in summer afternoons, this week of water science activities is easy to set up and fun to repeat.
Grab your FREE Water Science Camp Week below, or grab the complete printable pack with step-by-step instructions, bonus projects, and all the planning done for you.
🔎 Make sure to look through all of our camp theme weeks here! Tip: They work well anytime of the year for instant learning and fun!
What Do Kids Learn with Water Science?
Water is an amazing tool for exploring science! During Water Camp, kids will learn:
- States of matter and phase changes (solid, liquid, gas)
- Scientific observation and experimentation
- Properties of water, like surface tension, density, and solubility
Water science opens many learning opportunities, from experiments to art to outdoor play!

Water Science Activities for Kids
You can try one activity per day or mix and match based on interest. All experiments use simple materials and can be adapted for different ages.
Melting Ice Challenge (3 projects to try)
Can you slow down or speed up melting ice? Experiment with salt, baking soda, or materials like foil and plastic wrap.
🔍 Concepts: Heat transfer, phase change, insulation
What Dissolves in Water?
Test different substances—sugar, pepper, sand, oil—and see what dissolves and what doesn’t. You can also try this with candy!
🔍 Concepts: Solubility, mixtures vs. solutions
Drops of Water on a Penny
How many drops can you fit before it spills over? This experiment is great for observing surface tension and practicing patience.
🔍 Concepts: Surface tension, cohesion
Walking Water Experiment
Watch colored water “walk” between cups using paper towels. This is a colorful and exciting way to explore capillary action. You can also try this “grow a rainbow” version here.
🔍 Concepts: Absorption, capillary action, color mixing
Oil and Water Lava Lamp
Mix oil, water, and food coloring, then drop in an antacid tablet for a bubbling lava lamp effect.
🔍 Concepts: Density, polarity, chemical reaction
Leak-Proof Bag
Push pencils through a zip-top bag filled with water without spilling a drop. It’s not magic—it’s science!
🔍 Concepts: Polymer structure, surface tension
Skittles Painting
Dissolve Skittles in water and paint a rainbow masterpiece with the colorful sugar water. Of course, you can set up the classic skittles experiment as well.
🔍 Concepts: Color diffusion, solubility
Coffee Filter Flowers
Create beautiful, watercolor-like flowers by soaking coffee filters in water with markers.
🔍 Concepts: Chromatography, absorption, evaporation
Add a Water-Themed Art Project!
Looking for more? Try a Monet-Inspired Bridge Painting with watercolors and mixed media techniques. Explore impressionism while building fine motor skills and creativity.
Extension Activities for a Water Themed Camp
Nature Walks: Take nature walks near bodies of water such as ponds, rivers, or lakes. Encourage kids to observe and document the plants and animals they see and discuss the importance of water ecosystems. Use our free River and Stream Explorer Guide [here].
Water Conservation: Use this theme to teach kids about the importance of water conservation. Discuss simple ways to conserve water at home, such as turning off the faucet while brushing their teeth or fixing leaky faucets.

Frequently Asked Questions (FAQ)
Q: What is water science for kids?
Water science explores basic chemistry and physics concepts like surface tension, density, and absorption using experiments and activities with water.
Q: What age is Water Camp best for?
These activities are ideal for ages 5–10, though younger children may enjoy them with adult help, and older kids can dig deeper into the science.
Q: Are the supplies expensive?
Not at all! Most experiments use items you already have at home like plastic bags, cups, water, food coloring, and kitchen basics.
Q: Is this safe for younger kids?
Yes! All activities are kid-friendly and use safe materials. Always supervise water play and small items to ensure safety.
Q: Do I have to do it as a full camp?
Nope! You can use it as a week-long theme or spread activities throughout the summer. Everything is flexible.
