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.
2. Crystalized Words as a Creative Project: You could embark on a creative project where you embed words or letters into crystal formations or sculptures. This could be done using resin, glass, or actual crystals. Each crystalized word could have a specific meaning or significance in the context of your project.
If you have a more specific concept or idea in mind related to “crystalized words,” please provide additional details, and I’ll be happy to provide more tailored information or suggestions.

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:
Materials Needed:
1. Raw eggs (for testing)
2. Variety of materials for constructing the egg containers (e.g., paper, cardboard, straws, tape, rubber bands, cotton balls, foam, balloons, bubble wrap, etc.)

4. Optional: Markers, paint, or decorative materials for customization
5. Measuring tape or ruler
6. A safe location for egg drops (outdoors or a high platform indoors)
7. Safety goggles for participants (recommended)
Procedure:
1. Understand the Challenge: Explain the challenge to participants. They need to design a protective container or device that will keep a raw egg intact when dropped from a specified height. The goal is to minimize the force of impact.
2. Set Height Parameters: Determine the height from which the eggs will be dropped. You can start with a lower height and gradually increase it for subsequent rounds to make the challenge more interesting.
3. Design Phase: Allow participants time to brainstorm and design their egg containers. Encourage them to consider principles of physics, such as shock absorption, cushioning, and structural integrity.
4. Materials Selection: Provide a variety of materials for participants to choose from. They can use these materials to build and customize their egg containers. Emphasize the importance of using the materials efficiently.
5. Construction: Participants should construct their egg containers according to their designs. They can use scissors, tape, and other tools as needed. Remind them to be creative but also practical in their designs.
6. Testing: Each participant or team should test their egg container by placing a raw egg inside and then dropping it from the predetermined height. Inspect the egg after each drop to see if it survived intact. If it breaks, participants can make adjustments and try again.
7. Record Results: Keep track of which containers successfully protect the egg and which ones do not. You can have a leaderboard to showcase the most successful designs.
8. Iterate and Improve: Encourage participants to learn from each drop, make improvements to their designs, and test again. This iterative process is an essential part of the challenge.
9. Winners and Awards: Consider giving awards for categories like “Most Creative Design,” “Best Use of Materials,” and “Most Effective Egg Protector.”
The Egg Drop Challenge is a great way to foster creativity, critical thinking, and teamwork while introducing STEM concepts in a fun and engaging manner. It also provides a hands-on lesson in the physics of force and impact.
