A gardener is concerned that her greenhouse is getting too hot from too much light, and seeks to shade her plants with colored translucent plastic sheets. What color should she use to reduce overall light energy, but still maximize plant growth?

A) green
B) blue
C) yellow
D) orange
E) any color will work equally well

A. Green

Explanation:

A green green house shade will be best to suit this purpose because green shades are best for nursery stock, pot plants, caladiums, lettuce and plants that require partial shade.

b) Blue

Explanation:

The color of light reflecting on plants tend to to affect photosynthesis (how the plants produce their food). Plants needs all visible colors of light except green. Plants react in different ways to different colours of light they are exposed to. The red light helps plants but only helps then to grow flowers, the yellow colour is not ideal because it will do little to protect from heat due to too much light. But the blue colour helps in good vegitative growth of the leaves and it also does a good job in absorbing heat.

Since the gardner wants to shade her plants with coloured transluscent plastic sheets, the ideal plastic sheet colour will be blue, because blue is a good absorber of heat and it also does tremendously well in the vegetation of plants.

explanation:

picture a world where computers are building made-to-order personalized robotic arms and synthetic organs, drones are circulating above mars! due to the rapid growth of technology, the future has never been more unpredictable, and it presents a huge challenge in education: we are teaching students how to work in a future that we have never been unsure of. it is widely predicted that in eight years’ time, there will be more jobs in the fields of science, mathematics, technology and engineering than in any other discipline. and, as the technology continues to develop, it will soon become clear that addressing social problems will involve more innovative thinking, and analytical and technical knowledge than ever before. undeniably, there are no subjects that encourage innovative and creative thinking, deep thought, problem solving and independence more than the stem subjects. while it is widely commented on that there is a need to reimagine the ways stem subjects are taught in schools by embracing a more interactive and innovative approach to appeal to more students, it should come as no surprise that some of the most reputable educational organizations in the world are already implementing changes to embrace stem. harvard, for example, announced in 2014 that they were increasing their computer science faculty by over 50% and has since introduced computer science as a core subject for all freshmen. the urgency of supporting stem subjects at a young age is becoming more relevant than ever, as adopting a keen interest in the curricula needs to happen early. however, beyond the age issue is one of gender.
