Plants can grow in artificial light, but artificial light isn’t as intense as sunlight and has less red and blue light than sunlight. LED lights used in special indoor growth chambers reduce the difference between artificial light...

Brit looks back on our eleventh month on Nature League, when we explored the theme of rhythms.

This week on Nature League, Brit Garner explores the rhythms of life on Earth by breaking down a recent scientific journal article about circadian rhythms of reindeer in the Arctic.

n this live-action program viewers will learn experiments are a key step in the scientific process and to conduct a successful experiment, the scientist must know how to design, plan, and execute an experiment. Students will come to...

In this live-action program viewers will learn that controls and variables are the basis for applying the scientific method in a lab experiment. Students will come to understand that in an experiment, variables change, while the other...

Expert scientists and researchers from NASA’s Johnson Space Center gather to highlight the scientific breakthroughs aboard the International Space Station during a recent panel discussion celebrating 20 years of continuous human presence...

The soil beneath your feet, the food on your table, the roof over your head... these are luxuries on Mars. Getting there isn’t a problem, it’s surviving once you land. In this episode we’ll sit down with scientists and engineers...

The video discusses a required biology practical activity that involves investigating the effects of light on plant growth. The presenter explains how to develop a hypothesis related to the growth of mustard seedlings based on the...

For the first time, a NASA satellite has quantified in three dimensions how much dust makes the trans-Atlantic journey from the Sahara Desert to the Amazon rainforest. Among this dust is phosphorus, an essential nutrient that acts...

This video lesson explains how to use line plots to solve problems and interpret data. It emphasizes the importance of organizing data and being accurate with spacing when creating line plots. The example used in the video involves a...

The past decade is the warmest on record since instrumental measurements began in the 1880s. Previous research suggested that in the '80s and '90s, warmer global temperatures and higher levels of precipitation -- factors associated...

It describes the need for mineral nutrition in plants, lists the criteria for essentiality of an element and classifies the minerals required by plants as macro and micronutrients.

This clip explains the key role of the plant hormone Auxin in controlling growth in plants.

Plant Physiology and Chemistry Set: 5. This clip explains

In this video we are going to look at a few different ways in which plant hormones can be used.



Plant growth hormones (auxins) can be used as selective weedkillers. The selective weedkillers contain growth hormones,...

Explain the process and phases of plant growth, growth curves and factors controlling growth in plants.

This video provides an introduction to the concept of functions in mathematics. The lecturer compares functions to machines that take an input, apply a specific rule or operation, and give an output. The video also provides examples of...

We've already learned a little bit about plant hormones, but let's dig a little deeper so that we can really examine the different ways that plants can respond to stimuli. These are called tropisms, and they can be positive or negative,...
