Big Chemistry Experiments for Little Kids A First Science Book for Ages 3 to 5 (Big Experiments for Little Kids) by Dr....

Imagine the joy on a child’s face as they watch colors swirl in a homemade lava lamp or see baking soda and vinegar erupt like a tiny volcano. Big Chemistry Experiments for Little Kids by Dr. Megan Olivia Hall PhD MEd is more than just a science book—it’s a gateway to wonder, discovery, and hands-on learning for preschoolers.

As a parent or educator, finding engaging, age-appropriate STEM activities can be challenging. This book bridges that gap beautifully, offering 20 safe, simple, and exciting experiments designed specifically for children ages 3 to 5. But does it truly deliver on its promise of making chemistry fun and accessible for the youngest learners? Let’s dive in.

Big Chemistry Experiments for Little Kids is structured as a step-by-step guide that introduces foundational chemistry concepts through play. Each experiment is:

• Short and simple (most take 5-10 minutes)
• Uses household items (no lab equipment needed)
• Includes clear instructions and explanations

Some standout experiments include:

• "Fizzing Colors" (a baking soda and vinegar reaction with food coloring)
• "Magic Milk" (exploring surface tension with dish soap)
• "Rainbow Density Tower" (layering liquids of different densities)

The book also includes safety tips, discussion questions, and real-world connections to help adults guide children through each activity.

Dr. Megan Olivia Hall isn’t just a scientist—she’s an award-winning educator with a PhD in STEM curriculum development. Her background shines through in how she:

• Breaks down complex ideas into toddler-friendly language
• Encourages observation and questioning (key scientific skills!)
• Prioritizes safety and simplicity

Unlike many kids’ science books that focus on flashy results, this one emphasizes process over product, helping children develop critical thinking and curiosity.

The book’s conversational tone makes it feel like a friendly teacher is guiding you. Key strengths:

• Clear, visual instructions with minimal text (perfect for short attention spans)
• "Why It Works" sections that explain the science in simple terms
• Encourages repetition and variation (e.g., "What happens if we use cold water instead of warm?")

One minor critique? A few experiments (like the "Ice Cream in a Bag" activity) require pre-planning (e.g., freezing ingredients ahead of time), which might frustrate spontaneous learners.

---

Beyond the wow-factor experiments, this book subtly teaches:

• Cause and effect ("If I mix these, what happens?")
• Patience and observation (some reactions take time)
• Environmental awareness (e.g., discussing where ingredients come from)

It also normalizes failure—because in science, unexpected results are part of the learning process!

As a parent, I’ve tried many "science for kids" books, but this one stood out because:
✅ Minimal mess (most experiments use a baking tray for easy cleanup)
✅ Instant engagement (my child begged to do "Fizzing Colors" three days in a row)
✅ Real learning (she now asks, "Is this a chemical reaction?" when mixing bath toys!)

The biggest win? It made science feel magical yet approachable—no fancy gadgets required.

How does it stack up against similar titles?

Feature	Big Chemistry Experiments	Other Preschool Science Books
Age-Appropriate	✅ Perfect for 3–5	❌ Often too complex
Everyday Materials	✅ Uses pantry staples	❌ May need special supplies
Educational Depth	✅ Explains "why"	❌ Focuses only on "how"

For toddlers and preschoolers, this is one of the best introductions to hands-on chemistry available.

---

• Accessible for non-science parents (no PhD needed!)

• Encourages parent-child interaction

• Builds foundational STEM skills

• A few experiments require prep (not all are spur-of-the-moment)

• Limited diversity in photos (most images feature Caucasian children)

---

Ideal for:

• Parents of curious 3–5-year-olds
• Preschool and kindergarten teachers
• Homeschoolers seeking hands-on science

Not ideal for:

• Older kids (check out The Curious Kid’s Science Book for ages 4–8)
• Families wanting elaborate experiments (these are simple by design)

---

"Science isn’t about getting the ‘right’ answer—it’s about asking great questions."

Try asking your child:

• "What do you think will happen if…?"
• "Why did the colors mix that way?"

Early STEM education is critical for closing gender and racial gaps in science fields. Books like this help democratize science access by making it fun, affordable, and inclusive from the start.

---

Big Chemistry Experiments for Little Kids is a delightful, educational, and practical introduction to chemistry for preschoolers. While no book is perfect, this one comes remarkably close—offering just the right mix of fun and learning.
