We know that water is essential for living. Here’s the other thing about H20: it can teach us some interesting things about science, too!
We have found a few at-home experiments from steampoweredfamily.com to help you and your children learn about water and foster curiosity, inquisitiveness and resilience during times when we are all spending more time at home together. This is the first of three blogs to provide you and the favorite children in your life with fun and educational experiments centered around water.
Water Lab: A STEM Experiment Exploring Safe Drinking Water
Objective: Examine the chemical makeup of different water sources.
Step 1: Collect a few water samples from a few different sources to examine the chemical makeup of each. Make sure you put them into clean, sterilized containers so that you don’t contaminate the sample and ruin the experiment. A few examples of water sources could be a nearby creek, collected rainwater, tap and bottled water.
As with all science, it’s important to document your findings.
Step 2: Line up the samples to examine them visually, recording what you see, color, anything in the water needs to be noted. Sometimes you’ll have organisms in the water if you collect it from outdoor sources like a lake or creek.
If you want to compare the samples easily and orderly, there are affordable options for test tubes with racks on Amazon.
From here, test the water samples for pH, hardness, alkaline and bromine levels. Water test strips can be found in many stores and online, for example, Amazon has a set of 50 for $15.
You’ll be able to see the differences in water depending on the source, and have a conversation about how water protection and treatment is important.
CSWR tests water for various contaminants and chemicals to keep the water you drink safe and clean. Also we ensure that any water we put back into the environment won’t harm the surrounding plants and animals in our communities.
