Cohesion and Adhesion

I took these photos at the Missouri Botanical Garden after a summer storm. Notice how the water appears on each item below. What do you wonder? Scroll under the photos to learn two properties of water.

I captured this photo one foggy morning last fall. Use small spray bottles to mist water onto webs to replicate what happened.

Cohesion and adhesion are properties of water. Cohesion occurs when water molecules are attracted to each other and clump (bond) together in drops. Adhesion occurs when water molecules are attracted to other materials.

Millipedes and Centipedes

Centipedes are often found in basements and gardens. What do you observe? Are they insects?

I had millipedes (Milly and Jilly) in my science lab. How are arthropods, millipedes and centipedes, alike and how do they differ?

To learn the difference between the two, watch the video below. Click here for additional information.

The Latin root word ped means foot, milli means thousand, and centi hundred. Do these creatures really have that many legs?

Pincushion Garden

I discovered pincushion gardens at the Missouri Botanical Garden. Thinking it would be fun to plant a garden like this!

Pincushion gardens were first introduced in the 1850s in England. In the 1900s, circular pincushion beds, made of succulents and cacti in intricate symmetrical designs, were planted in the Missouri Botanical Garden. Click here to learn more.

Climatron and Corpse Plant

While I was in St. Louis, I visited the Missouri Botanical Garden. “Founded in 1859, the Missouri Botanical Garden is the nation’s oldest botanical garden in continuous operation and a National Historic Landmark.

The Garden is a center for botanical research and science education, as well as an oasis in the city of St. Louis. The Garden offers 79 acres of beautiful horticultural display, including a 14-acre Japanese strolling garden, historic architecture, and one of the world’s largest collections of rare and endangered flora.”

One of the highlights of my visit was the Climatron which has a tropical rainforest theme. “In 1976 it was named one of the 100 most significant architectural achievements in United States history. The term “Climatron” was coined to emphasize the climate-control technology of the greenhouse dome.”


In the Climatron, was the rare corpse plant. It is scheduled to bloom in the next couple of weeks.

Fireworks

I watched fireworks at my sister’s home in Kirkwood, MO. As I watched this impressive display, I wondered about the history of fireworks and how the colors and shapes are created. Check out the links below to find out more.
