Our 2025 Stem Kits
December Edition
1st-3rd grade
Paper Lanterns
Lunar New Year is a major festival celebrated in many Asian cultures, marking the start if the lunar calender, usually between late January and mid-February. It is a time for family reunions, feasts, red envelope gifts, dragon dances, and fire works to bring good fortune. The celebration lasts up to 15 days, ending with the Lantern Festival and each year is associated with an animal from the Chinese zodiac.
November Edition
1st-3rd grade
The Science Behind Popsicle Stick Harmonicas
Harmonicas made with paper and straws demonstrate principles of sound production and resonance. The vibrating reeds made from paper or straws produce sound waves when air flows over them, similar to traditional metal reeds. The shape and size of the paper or straw reeds affect the pitch and timbre of the sound produced. This simple construction allows for hands-on exploration of acoustic physics, including how vibration frequency and air flow impact sound quality.
October Edition
1st-3rd grade
The Science Behind Invisible Ink
Lemon juice invisible ink works through a simple chemical reaction that reveals itself with heat. When you write with lemon juice on paper, the liquid dries clear because it’s mostly water with a bit of citric acid. However, when you heat the paper, the acidic compounds in the lemon juice break down and oxidize faster than the surrounding paper, turning brown and making your hidden message visible. This reaction shows how organic materials, like lemon juice, respond to heat by changing color, illustrating basic principles of oxidation and heat sensitivity.

The Science Behind Grow a Plant
When you plant a seed and add water, it absorbs moisture, activating enzymes that start germination. The root grows first, followed by the shoot that seeks sunlight. Through photosynthesis, the plant uses light, water, and carbon dioxide to make its own food and release oxygen. The soil provides nutrients like nitrogen and potassium for healthy growth. This simple kit demonstrates how water, light, and soil work together to create life!
August Edition
1st-3rd grade
The Science Behind Mini Rocket Shooter
Paper rockets operate on principles of physics involving Newton’s law of motion and aerodynamics, They are propelled by compressed air or by the release of stored elastic energy, demonstrating concepts of energy transfer and conservation. The shape and size of the rocket affect its flight path, showcasing principles of stability and drag. Overall, paper rockets provide a hands-on way to explore fundamental scientific concepts related to forces, motion, and flight dynamics.

June Edition
1st-5th grade
The Science Behind Oobleck
Oobleck is a substance that weirdly behaves like both a liquid and a solid! When you light touch or pick up oobleck, it acts as a liquid, flowing smoothly. But, if you squeeze it or hit it, it turns solid! This fascinating transformation happens because of the unique properties of a mixture of cornstarch and water in oobleck.

The Science Behind Sponge Waterbombs
A sponge water bomb works because sponges have lots of tiny holes that soak up water like a thirsty plant. Water sticks inside the sponge until you squeeze it or throw it, making the water splash out! This happens because water likes to stick to things(adhesion) and also to itself(cohesion). When the sponge hits something, it squishes and pushes the water out!
March Edition
1st-5th grade
The Science Behind Spoon Catapults
A spoon catapult works by storing potential energy when pressed down and released it as kinetic energy to launch a projectile. When you release it, that energy launches the object forward. The shape of the spoon to send the object flying at an angle, making it go farther. Adjusting tension and stability can improve performance, making it a fun and simple way to explore physics!
