Invasive cattail leaf rockets

 Invasive cattails, especially Narrow-leaved Cattail (Typha angustifolia)

 grow rapidly and crowd other plants species, and also provide poor habitat.  But they can make great leaf rockets.  Click on the image (right) or on this link:

Guest Blogger Amelia Keng: How can technology-research reduce droughts in California?

How can technology-research reduce droughts in California?

For many years, California has not had an abundance of water. Climate change is only making conditions worse for farmers, city dwellers, and nature as they continue to have a lack of water. According to drought.gov, as of 2022, the state of California is experiencing 99.77% of moderate to exceptional drought. This means that around 37,243,577 of Californians are in drought, due to the significant lack of precipitation and groundwater. Although in the past years, California has seen a

Sealed Terrariums

In 1960, David Latimer planted a spiderwort sprout inside of a large glass jar, added a quarter pint of water, and then sealed it shut. He opened the bottle for the first time only 12 years later, in 1972, to add some water and then sealed it for good. 

The self-contained ecosystem flourished for more than 60 years as a perfectly balanced garden and self-sufficient ecosystem. 

The bacteria in the compost ate the dead plants and broke down the oxygen released, turning it into carbon dioxide, essentially forming a microcosm of Earth. 

For teachers:  This is a great project at the end of the year. It doesn't have to be this big, and it can even be a sealed aquarium (terrarium).  Next Fall you can invite your former students to stop in to see it.  To add a little more excitement, many types of insects, spiders, worms, snails and even flies can survive in a closed terrarium. Springtails, earthworms and woodlice are found in most closed terrariums.

April 13 high water exceeds forecast

 For all those times the prediction forecasts seem exaggerated.

Students Using Wikipedia for Research

Teaching Students How to Use Wikipedia as a Tool for Research

Wikipedia has moved far beyond its initial limitations, and is a helpful—and reputable—source for conducting research.

By Mike Caulfield, Sam Wineburg
January 24, 2024

Your middle school teacher threatened to give you an F if you cited it. A reminder hung menacingly in the computer lab: a thick black line slashing the word in two. Even now, you can find blanket dismissals bellowing from college websites: Wikipedia “isn’t a credible resource because anyone is allowed to be a contributor.”

In its early days, Wikipedia had no shortage of problems. Errors propagated like fruit flies. People used the site to spoof their friends and exact revenge on their enemies. The site’s flaws were legendary, sometimes scandalous. A 2006 article accused John Seigenthaler, an assistant to Robert Kennedy in the 1960s, of having a hand in Kennedy’s assassination. The false charge stayed on the site for 132 days before it was finally removed. But not before

Plant Hardiness Map

 Starting to think about spring planting season? Remember that USDA plant hardiness zones changed last year. The South Branch Valley in Hampshire County is now in Zone 7a, where it was previously in 6b (-5 to 0°F/ -20 to -17°C). The average lowest temperature has changed by 3 to 4 °F, even those places in Hardy County and that stayed in 6a or 6b.

Literature review as a research methodology

Our educator friends at Charles H. Flowers High School used literature reviews instead of science fair projects during Covid, and we realized this may be more valuable than the science fair.
