Mad Science – Full

Welcome back homeschooling families. For September, give your child a taste of what it’s like to be a scientist as we explore Mad Science activities in the Guadalupe River Park & Gardens. Students will use the ‘Kids First Chemistry Kit’ to learn about lab safety and how to use basic lab equipment. The Jr. Scientists will participate in spectacular science experiments including crystal creation, a vibrant color lab and bubbly gas lab. Join us to research simple chemical reactions from everyday life and analyze them in our mini labs, just like a real scientist! All materials will be provided.

Update: Mondays, Thursdays & Fridays are full!


Crystal Clear Science

September 12th/September 8th/September 9th

Crystals are fascinating marvels of nature. They form cubes, pointed needles, warped rectangles and other complicated shapes with smooth surfaces that sparkle in the light. During our crystal clear science activity students will learn about mysterious crystal formations and make their own rock candy to take home. Adventure out into the Guadalupe River Park & Gardens to learn the best way to find crystals in nature. Concepts covered: Lab safety, Saturated solution, Crystal formation, Mineralogy

Colorful Science Lab

September 19th/September 22nd/September 23rd

What would our world be like without colors? Colors make our world more exciting and vibrant. They accompany us everyday and influence us more than we imagine. In the Colorful Science lab, students will learn how carbon can wash away colors and how chocolate candy coatings can reveal what colors they’re made of. The class will then embark on a guided nature walk in the gardens in search of natural materials to create natural paints and pigments. Concepts covered: Chromatography, Primary, Secondary & Complementary colors

Fizzy Bubbly Science

September 26th/ September 29th/September 30th

Some gases have an odor, while others don’t. Most gases are also colorless, completely transparent, and invisible. During the Fizzy Bubbly Science lab, students will learn what the air that you breathe is made of, and what it has in common with candle fumes. We’ll conclude our mad science series by chemically inflating a balloon and creating an awesome and safe science “explosion” using our volcano model, vinegar and baking soda. Concepts covered: Gas and Pressure.

A unique setting…
The Guadalupe River Park & Gardens is an education destination like no other. A natural oasis located in the heart of downtown San Jose, the Guadalupe River Park & Gardens features 254 acres of park that include the Heritage Rose Garden, the Historic Orchard, a community garden, and 2.6 miles of trail that runs adjacent to the Guadalupe River. The GRPG provides a natural outdoor laboratory for science experiments and offers a creative and dynamic atmosphere for learning.A customizable education…
The Outdoor Environmental Science Program’s core curriculum covers a wide variety of current environmental science topics. Each class covers a unique theme within the environmental sciences, but your child can sign up for an individual class depending on his or her interests, come to several classes to cover a unit, or attend all the classes to build an interdisciplinary understanding of nature and science.A learning adventure…
The Guadalupe River Park Conservancy’s classes are unique, interactive adventures – children won’t learn science by listening to lectures, but will learn through activity-oriented lessons, science experiments, and scientific observations out in the park. Your child will be challenged, but will move, talk, think and play to learn. 

A healthier community…
More and more studies are indicating that spending time outdoors is vital to children’s academic development and health. Spending time in nature allows children to develop a connection with their surrounding community and become early stewards of the environment.


An ongoing interest…
When outdoors, children can see science playing out before their very eyes, develop powerful observational skills, and are exposed to the environmental sciences, an up-and-coming field worldwide. If your child’s interest is kindled by any or all of the OESP class topics, you can find more educational resources about that topic by clicking on the links that follow each class description, so you can be an active partner as your child explores their new favorite environmental science subject.
