1. Planting Buddy

Another unrestricted chance awaits you and your children or classmates with this endeavour. The goal is to build a tool that assists with seed planting. You can utilise any items you have lying around that would’ve been thrown out, just as the Egg Drop Challenge project. I enjoy making my device out of used but clean straws, cardboard boxes that I can cut into different shapes, small plastic or paper cups, and used tissue boxes. Unless you and your child are particularly handy and have small motors lying around, it isn’t motorised, but I believe hand power is far more effective. Here is a video to get you started if you need some motivation:


For even more recycled gardening and planting fun, if you’re feeling very adventurous, you may combine this project with the Recycled Garden project. 

2. Crystalized Words

“Crystalized words” is not a common term or concept in English, so I’m not sure exactly what you’re referring to. However, if you’re interested in something related to words and crystals, here are a couple of interpretations:
1. Crystalized Words as Metaphor: In a metaphorical sense, “crystalized words” could be used to describe words or language that are clear, precise, and well-defined, much like the facets of a crystal. It could be a way of emphasizing the importance of clarity and precision in communication.

4. Liquid Fireworks


“Liquid fireworks” is not a standard term or concept, but it can refer to a creative and visually captivating experiment or art project involving liquids that mimic the colors and patterns of fireworks. Here’s a fun and safe way to create a liquid fireworks display:
Materials Needed:
1. Milk
2. Liquid dish soap (preferably a variety with colors like blue, green, or red)
3. Food coloring (multiple colors)
4. A shallow dish or plate
5. Cotton swabs or a thin stick (for creating patterns)
Procedure:
1. Pour the Milk: Pour a small amount of milk into the shallow dish, enough to cover the bottom.
2. Add Drops of Dish Soap: Place drops of liquid dish soap onto the surface of the milk. You can create multiple drops in different areas.
3. Add Food Coloring: Add a drop or two of different food coloring to the drops of dish soap. You can use various colors to create a colorful display.
4. Observe the Reaction: As the soap interacts with the fat in the milk, it will create swirling patterns and bursts of color, somewhat resembling fireworks. You’ll see the colors rapidly expand and mix.
5. Experiment with Patterns: To create different “firework” patterns, you can gently swirl the milk with a cotton swab or drag a thin stick through the mixture. Be careful not to mix it too vigorously; you want to maintain the colorful patterns.
6. Continue Experimenting: You can continue to add drops of soap and food coloring to create new bursts of color and patterns. Try different color combinations and patterns to make your “liquid fireworks” display more intricate.
7. Document and Enjoy: You can take photographs or videos of the evolving patterns. It’s a mesmerizing and educational experiment that demonstrates the principles of surface tension, chemistry, and fluid dynamics.
Remember that this experiment is safe and non-toxic, but it’s meant for observation and entertainment rather than consumption. Ensure proper supervision if children are involved. When you’re done, you can safely dispose of the mixture down the drain.
This “liquid fireworks” experiment is a creative way to explore the science of surface tension and chemical reactions while enjoying a visually stunning display reminiscent of fireworks.

5. Egg Drop Challenge

The Egg Drop Challenge is a classic STEM (Science, Technology, Engineering, and Mathematics) activity where participants design and build a protective structure to prevent a raw egg from breaking when dropped from a certain height. It’s a fun and educational project that teaches principles of physics, engineering, and problem-solving. Here’s how you can organize your own Egg Drop Challenge:
