Science Expeditions lets kids solve real-life scientific mysteries every month through science experiments, hands-on STEM activities and more! Every box includes a 16 page comic with scientific mysteries to solve through fun activities, an 8-page experiment guide, and even achievement badges for your lab notebook! This subscription is intended for children ages 9 and older.

This month, the box explores the principles of HYDROLOGY!

There’s also an info card for some online bonuses for more scientific fun! It features videos, tips, printables, and more,

Everything in my box!

Achievement Badge. Each month, your child can earn a sticker badge by completing the requires tasks. The badge is included inside the box and can be collected in the lab notebook.

Looking forward to filling this page with more badge stickers!

Science Expeditions: Hydrology Comic. Every box includes a 16-page comic book, complete with a glossary of terms and bonus activities.

As usual, they started the book with a letter from Sam and Sofia about their adventure this month. It also has a comic strip introducing the activities, what to expect in each, our goals we for each, and lessons that to be learned.

71% of the Earth’s surface is covered with water, but most of it, like oceans and seas, is undrinkable – and to make it drinkable, it has to go on a process called water treatment. This activity will make kids familiarize themselves with the step-by-step procedure of treating water to make it potable and suitable for agriculture.

Archimedes was a mathematician, astronomer, physicist, and Engineer from ancient Greece. Among his many innovations was a screw pump that would come to be known as the Archimedes Screw. It uses a spinning inclined plane to move water to a higher elevation. In this suggested activity, you create your own Archimedes Screw using simple materials that you can easily find in your household.

The next activity is a Water Audit. To get an accurate estimate of your daily water consumption, it has you track the gallons of water your family consumes to perform various activities each day!

The average person in the U.S. roughly uses 80-100 gallons per day. That means the average family of four might use up to 400 gallons per day.

The booklet has lots of great information about water consumption, including a comparison of the amount of water required to grow various foods. I appreciate the glossary’s use of images, too! It makes it a hundred percent easier to understand, and it is a lot more visually interesting

The activity materials are protectively packed inside a bubble wrap envelope.

Here’s everything we need for this month’s experiments!

Activity Guide. We’re ready to start with the experiments! But first, we need to look through this Activity Guide. The experiments that we’re about to do are constructing a Water Filter Column, making a Spinning Sprinkler, and performing a Rainbow-Colored Acid Test.

The activity sheet is a four-folded glossy brochure containing all the activities, step-by-step procedures for each, safety notes, and notes on potential applications of each activity in real life. .

These are all the items needed for the Water Filter Column activity!

This experiment tackles Earth Science and Environmental Engineering Chemistry and takes 30-60 minutes to complete.

How lovely to see that almost all the materials are already provided. My daughter started preparing them by herself. Her favorite part was creating “dirty” water to filter!

Once all the filter sections were filled with quartz sand, porcelain sand, activated carbon, and crushed granite, we began filtering our contaminated water.

The water slowly made its way down through the filter layers, with each layer removing some of the contamination.

The water we collected at the bottom wasn’t completely clear, but we could see that many contaminants had gotten trapped in our filter system and removed from the end product.

Water has a special property called cohesion, which makes its molecules stick together and pull each other as they move. In this experiment, we made a simple pump that takes advantage of the water’s sticky nature and makes it flow up and out to the ends of two plastic straws!

All you need to perform this activity is 3 feet of string, 3 plastic straws, and a stick. All were included in the box.

Here’s the final output! When you’re done assembling, just put it in a bowl with water and then spin it!

This spinning sprinkler is actually a simple pump. Spinning it exerts a centrifugal force that moves the water outward, up the inclined plane of the straw. The cohesive force of the water makes it function as a siphon, pulling more water into the tube, allowing you to shoot a steady stream of water out of the open ends.

The Rainbow-Colored Acid Test measures the acidity/pH level for a set of liquids. This test is usually used by scientists to check if water is safe for drinking.

The materials included for this experiment are pH strips and a pH scale.

For the pH test, we prepared small samples of several household items. Our lab instructions suggested many safe substances to test, so we didn’t need to use any bleach or other dangerous liquids. To test, we quickly dipped a pH strip into each liquid, waited for its color to change, and matched the result to the pH scale. We tracked the results in our lab notebook.

Learning about various scientific concepts is made more fun by Little Passports! This month’s box is all about water, and my daughter definitely enjoyed it. From making a water sprinkler, to testing out the acidity level of water, the experiments gave her hands-on experiences that really brought the concepts home. On top of the three main experiments, the booklet has a variety of stories and interesting activities, as well. It’s a well-rounded box and we’re always so impressed!
