Today, Carrie Anne is going to take a look at how those transistors we talked about last episode can be used to perform complex actions. With the just two states, on and off, the flow of electricity can be used to perform a number of logical operations, which are guided by a branch of mathematics called Boolean Algebra. We’re going to focus on three fundamental operations - NOT, AND, and OR - and show how they were created in a series of really useful circuits. And its these simple electrical circuits that lay the groundwork for our much more complex machines.

The lessons in this issue of Smithsonian in Your Classroom introduce the work of botanists and botanical illustrators, specifically their race to make records of endangered plant species around the world. “Very little of the world’s flora has been fully studied,” says one Smithsonian botanist, “and time is running out.” In the first lesson, students gets to know six endangered plants. They examine illustrations, photographs, and dried specimens of the plants as they consider this question: If a scientist can take a picture of a plant, are there advantages in having an illustration? They go on to consider some of the big questions that botanists themselves must ask: Which of these species are most in need of conservation efforts? Are any of these plants more worth saving than others?In the second lesson, the students try their own hands at botanical illustration, following the methods of a Smithsonian staff illustrator. All that is required for the lesson are pencils, markers, tracing paper, and access to a photocopier.

PHYSICAL SCIENCE Have you ever heard of Gak? Take this hands-on activity to the next level and make your own bouncy balls so you can learn a little something about polymers.
ABOUT THE SCIENCE In response to the July 22, 2016 Health Canada advisory, the bouncy ball experiment was recently updated.
Balls have been around for thousands of years and, believe it or not, the earliest balls were made of stone and wood! Not much bounce to those first ones!Bouncing balls were first made with natural rubber, but now, they can also be made of plastics and other polymers. Polymers are molecules made up of repeating chemical units, and they can be either natural or synthetic. Natural polymers are wool, silk, and natural rubber, whereas synthetic polymers can be made of nylon, silicone, or synthetic rubber. Bouncy balls (as a toy), were invented by a chemist who was experimenting with rubber. He found when he compressed rubber together under about 3500 pounds per square inch (psi) the result was a really durable sphere capable of extremely high bounce. Other factors that affect a ball’s ability to bounce are: temperature, outside coverings, different surfaces for bouncing and whether or not the ball is solid or inflated with air

Students examine how different balls react when colliding with different surfaces, giving plenty of opportunity for them to see the difference between elastic and inelastic collisions, learn how to calculate momentum, and understand the principle of conservation of momentum.

Building on lessons learned over several summers, Kristin Raab—Health Impact Assessment and Climate Change Program Director in the Environmental Health Division of Minnesota’s Department of Health—packaged information from diverse communities into a cohesive toolkit that communities of all sizes can use to prepare for heat waves. The Minnesota Extreme Heat Toolkit describes changing weather conditions in Minnesota, the magnitude of potential health consequences from extreme heat, and key steps communities can take to prevent heat-related illnesses and deaths. The toolkit acknowledges that extreme heat response plans will vary with the size of the community and the habits of its residents: examples from the mostly rural Olmsted County and the urban centers of Saint Paul and Minneapolis illustrate a range of community plans that could be useful in Minnesota and beyond.

BrainPOP invites students to discover, play and create, enriching and deepening their understanding of topics across the curriculum. Children are encouraged to make movies out of images, build maps and develop their block-based coding skills. BrianPOP Jr. targets children from 0 to 3 whereas BrainPOP focuses on K-12 grade children.

Students learn about the similarities between the human brain and its engineering counterpart, the computer. Since students work with computers routinely, this comparison strengthens their understanding of both how the brain works and how it parallels that of a computer. Students are also introduced to the "stimulus-sensor-coordinator-effector-response" framework for understanding human and robot actions.

Students learn about and experiment with the concept of surface tension. How can a paper clip "float" on top of water? How can a paper boat be powered by soap in water? How do water striders "walk" on top of water? Why do engineers care about surface tension? Students answer these questions as they investigate surface tension and surfactants.

Students are introduced to the respiratory system, the lungs and air. They learn about how the lungs and diaphragm work, how air pollution affects lungs and respiratory functions, some widespread respiratory problems, and how engineers help us stay healthy by designing machines and medicines that support respiratory health and function.

Students use a simple pH indicator to measure how much CO2 is produced during respiration, at rest and after exercising. They begin by comparing some common household solutions in order to determine the color change of the indicator. They review the concepts of pH and respiration and extend their knowledge to measuring the effectiveness of bioremediation in the environment.
