Summer is just around the corner, and we know that a lot of parents will need ways to keep their kids entertained while still learning and exercising their creativity. But how do you keep your kids entertained without needing too many materials or making too much of a mess? We’ve come u...
Soupy Science: Investigate How Dried Beans Absorb WaterScience Buddies
A book is a great way to introduce a toddler science activity. Go to the library or a bookstore and find a book on plants. Plants absorb water through their roots through a process called transpiration. The water travels up tubes in the stems to all parts of the plants, and is used...
On Earth that usually isn't a problem because plants absorb CO2. Yet gardening space is limited on the ISS, which forced engineers to devise other means of removing excess carbon dioxide. After the electrolysis process kicks in, some of the hydrogen reacts with the accumulating CO2. A byprod...
The roots soak up water, collect nutrients, anchor the plant and, in some species, spread out to grow new plants. A plant can only do these things effectively if the soil is right. The soil needs to be loose enough that the grass roots can spread easily, absorbent enough that it will...
These waves are fairly complex, but you can imagine them as similar to waves on water. They have peaks and troughs, and they travel in a straight line until they encounter an obstacle. Obstacles can absorb or reflect light, and most objects do some of both. Reflections from completely smoo...
Initially, at least, the idea would be to couple such systems with existing or planned infrastructure that already processes seawater, such as desalination plants. “This system is scalable so that we could integrate it potentially into existing processes that are already processing ocean water or ...
3. Plants absorb the nitrates and clean the water: The nutrient-rich water flows through the grow beds where the plants take up the nitrates as food. In the process, they clean the water by removing these nutrients. 4. Clean, oxygented water returns to the fish tank: The filtered water...

Taking carbon dioxide from the ocean could increase its natural ability to remove emissions from the atmosphere, like wringing out a sponge to make it more absorptive.
