Henri Rousseau, a French Post-Impressionist painter who worked in the so-called “Primitive” manner, was a self-taught artist who may be best known for his depiction of scenes of jungles. He famously claimed that he has “no teacher other than nature.” Batty, Michael (4 April 1985). "Fractals – Geometry Between Dimensions". New Scientist. 105 (1450): 31.

Vortex streets are zigzagging patterns of whirling vortices created by the unsteady separation of flow of a fluid, most often air or water, over obstructing objects. [64] Smooth ( laminar) flow starts to break up when the size of the obstruction or the velocity of the flow become large enough compared to the viscosity of the fluid.

His photographed works in nature depict deliberate placement of natural materials. While he started out as a painter, he was moved by the beauty of nature and the necessity to comply with the laws of nature. Lorenz, Edward N. (March 1963). "Deterministic Nonperiodic Flow".

From landscapes, animals, gardens, rivers, seascapes and more, artists have a wide variety of natural subjects to depict in their works. His work could inspire printing with tree stumps or even going outside and finding natural areas that could be printed. A conversation on the beauty of the rings of a tree is also another idea to use after viewing his work. Walter Mason has a beautiful perspective of the natural world visible in his photographs. Many pieces involve the arranging and rearranging of natural elements into unique designs. He often uses leaves, stones, ice, and flowers.

In this introduction, there are many aspects of flower biology that we have left untouched. The relationships between flowers and pollinators are fascinating, as are the stories about what actually attracts the pollinators to their flower partners (see, for example, the post Lanterns of the Western Woods). Some plants self-fertilize, while others have developed elaborate mechanisms to avoid self-fertilization. Even the anatomy of flowers is far more diverse than we have touched on here—consider, for example, the flowers and seeds of grasses, including the cereal grains that we depend on for so much of our sustenance. If you have ever been fortunate enough to cycle through the small, picturesque countryside of Nuenen, Holland, you will immediately understand where Vincent Van Gogh drew his inspirations from.

Looking for something different

Barry Van Dusen creates paintings of landscapes, botanicals, birds, and other animals. Many of his works are done en plein air, and some are done within his studio using sketches he has done from life. von Kármán, Theodore (1963). Aerodynamics. McGraw-Hill. ISBN 978-0070676022. . Dover (1994): ISBN 978-0486434858. Frequently I get students who opt for art as they really enjoy detailed, observational drawing. Sarah Simblet is a great artist to have up your sleeve for this sort of student. Simblet is known for her anatomical and botanical drawings. She has three botanical books published. She draws every sort of plant often detailing the roots, stems, leaves, flowers, and fruits.

His works are made from wood but I can imagine successful paper or card versions being created in the art room. Calceolate flowers are very distinctive, and it’s an uncommon shape. The term translates from the latin as shoe-like, or slipper-like. The only examples of calceolate flowers I can think of are the slipper orchids, none of which I’ve illustrated. Calceolate flowers are bilaterally symmetrical, so they are zygomorphic. Saccate flowers are zygomorphic, or bilaterally symmetrical. Unfortunately, the only example I could find was the Nemathus. Alas, it;s another plant I haven’t yet illustrated. Stellate flowers are interesting. They’re star shaped, and radially symmetrical. But the most interesting thing about these actinomorphic blooms is that they consist of tepals, not petals. “What”, I hear you cry “is a tepal!?” Some flowers have sepals and petals which are so similar as to be almost identical. In many flowers, the sepals are very different from the flowers, and mostly green.The artists on this list were chosen because of their popularity and high level of artistic achievement. It also includes a beautifully illustrated PowerPoint presentation to help add structure to your 'Tone and Natural Forms' art lesson, as well as a teaching plan that outlines success criteria for the lesson, helping you to assess your class's development. Why is it important to teach Natural Forms in Art Classes? The first thing to consider is the axis of symmetry. Does the flower have bilateral symmetry? Does it have a clear top and bottom, with two similar sides? If you cut it in half would both sides be mirror images? This is known as Zygomorphic symmetry. Violets show this form.

I was a professor of biology at the University of Washington in Seattle from 1969 to 2002. My specialty for all of my academic life was neuroscience, but the very first love of my scientific life was the world of plants. It was peering through a microscope at the brightly colored petals and stamens of an Emperor tulip during my first college course in biology that got me hooked, that literally kept me up at night trying to learn as much about living things as I could. Not only that, it played quite a role in my courtship of Yvonne, whom I married a few months after graduation and with whom I continue to share life, love, and interests 55 years later.

How to use tone when drawing natural forms in art classes?

I will guide you through some simple techniques to understandhow to really look at the natural forms and translate these into beautiful sketches. In this course we will:
