Water Refraction

I decided to do a fun water refraction experiment with my kids. I filled a clear bowl with water 💧 and put it in the sunlight. I asked my kids to look closely and notice what happens when we put objects in the water. I explained how it happens because of light bending in water.

Static Electricity

I chose to demonstrate a fun static electricity activity to my children. I massaged my hair with a balloon that I took. Then, I moved it close to small pieces of paper on a table. The paper bits stuck to the balloon! 

My children looked on in amazement. I gave them balloons 🎈 to rub in their hair because they wanted to try it, too. 

We discussed how the static electricity caused the balloon to grab the tiny pieces. It was a simple, fun, and educational experiment that the kids enjoyed.


When demonstrating science activities like static electricity ⚡️ with kids, engage their curiosity by allowing them hands-on experience. Encourage them to try the experiment themselves. It fosters understanding, sparks their interest, and makes learning enjoyable. Experimentation and discussion afterward build up their understanding of the scientific concepts.

Sink or Float

I organized a fun Sink or Float experiment for my kids. We gathered different objects from around the house, like a toy car 🚗 , a sponge, and a coin 🪙 . 

We filled a tub with water and took turns guessing if each item would sink or float. It was exciting to watch as we dropped them one by one.


To enhance the Sink or Float experiment, involve predictions before testing each item. Encourage reasoning behind guesses and encourage critical thinking. Expand by discussing density or shape’s role in the buoyancy of objects. Document results for comparison and consider unexpected outcomes as opportunities for further exploration.

Marble Run

I introduced them to a fun Marble Run project. First, I gathered some cardboard tubes, old paper towel rolls, and marbles. 

Together, we built a twisting, turning marble maze. I let my kids decide the path, and we connected the tubes with tape. We dropped the marbles in and watched them zoom through the maze we created!


Encourage creativity and problem-solving by providing diverse materials for constructing Marble Runs. Engage kids in designing the maze, fostering decision-making and spatial skills. Let them experiment freely to discover how changes in tube angles and connections affect the marble’s journey.

DIY Thermometer

First, we gathered a clear plastic bottle, water, rubbing alcohol, food coloring, and a straw. We mixed equal parts water and rubbing alcohol in the bottle and added a few drops of food coloring. 

Then, I sealed it and taped a straw inside. When we held the bottle, the liquid rose 🌹 in the straw. We talked about how the liquid rises and falls when it’s hot or cold. It’s a fun and easy way to learn about temperature.

To engage kids in understanding temperature, create a DIY thermometer using a clear bottle, water, rubbing alcohol, food coloring, and a straw. 

Equal parts water and alcohol, combined with food coloring, demonstrate temperature 🤒 changes. As the liquid moves in the straw, explain how it responds to heat and cold for an interactive science lesson.

Magnets Exploration

I brought out magnets of different sizes and shapes. We explored what they stick to around the house, like the fridge and some toys. 

I showed how magnets 🧲 attract certain things, and we played with making things stick together or push apart. 


When exploring magnets with kids, start with everyday objects to showcase their magnetic properties. Encourage hands-on experimentation by allowing them to discover what attracts and repels.

Shadow Tracing

I introduced my kids to Shadow Tracing, a fun game where we trace shadows of everyday things. We place toys 🧸 or objects on paper and outline their shadows with crayons or markers. We chat about how shadows change with light angles, just like clues in a detective 🕵️ story.

For a fun educational experience, combine play with education. Engage kids in Shadow Tracing by using various light sources and exploring how shadows alter with angles and distances. Encourage discussions on shape recognition, fostering curiosity about light behavior.

Egg Drop Challenge

I decided to create an exciting Egg Drop Challenge for my kids! We gathered pillows, cotton balls, and a cardboard box 📦 .
