Massive Database of 182,000 Leaves Is Helping Predict Plant Family Trees
The story of a plant is etched in its leaves. A tree growing in a cold environment with plenty of water is more likely to have large leaves with many serrated teeth around the edges. But if the same species lives in a warm, dry region, its leaves are likely to be smaller and smoother. Now, an atlas that traces the shapes of 182,000 leaves from 141 plant families and 75 locations around the world shows promise for refining scientists’ ability to read that story.

Plant Architecture and Its Evolutionary Implications — In Defense of Plants
Another interesting finding borne from these models is that there doesn't seem to be strong correlations between architecture and phylogeny. Although species within a specific genus often share similar architecture, there are plenty of exceptions. What's more, the same form can occur in unrelated species. For instance, Aubréville's model occurs in at least 19 different families. Similarly, the family Icacinaceae, which contains somewhere between 300 and 400 species, exhibits at least 7 of the different models. Alternatively, some families are architecturally quite simple.

11 class activities with sensors you didn’t know your phone had
Mobile devices can do more than we imagine! Rebecca and Chrystian Vieyra developed apps for classrooms to tap into their sensors. (Google Hangout screenshot) Smartphones and tablets are powerful devices that people use every day to make their lives easier. They’re even smarter than we give them credit for. Most of them have sensors we never knew they had.

Car and Vehicle Science Experiments
Cars are great subjects for science experiments because they are built to move. Cars need fuel to power their engines. The engine turns the gasoline into mechanical energy that moves the gears.
Making Maths: Clinometer
A clinometer is a tool that is used to measure the angle of elevation, or angle from the ground, in a right - angled triangle. You can use a clinometer to measure the height of tall things that you can't possibly reach to the top of, flag poles, buildings, trees. Follow the directions below to create your own clinometer.
AMKK（東 信、花樹研究所）
Botanical Animation “Story of Flowers” Produced by AMKK Directed by Azuma Makoto Illustration by Katie Scott Animation by James Paulley < ABOUT > This “Botanical Animation” is an independent art project from AMKK, who create various works of art using flowers and plants. The animation was developed for kids to show the life cycle of flowers. Azuma made the original story and requested London-based illustrator and animator Katie and James breathe life into the animation with their beautiful work. < STORY > Many different flowers are growing beautifully and strongly in this world. Taking their roots in the earth, sprouting, blooming, pollination by birds and insects, living on in spite of rain, wind and storms. They pass on the baton of life, rebirth and decay. Everything is so in a continuous, endless cycle.
