Intro This course was meant to help explain phenomena that happen every day, all around us. Typically, we used math and equations in this course. However, there are many ways to explain our world, and one of them is to capture an image of a scientific phenomenon (event, occurrence, etc) related to physics or chemistry.
The Task To capture an image(s) that shows a scientific phenomenon. This can be done by photographing something that shows physics or chemistry in the world, creating an optical illusion, or another form of art approved by me. Then, you will need a 2-page, double spaced, 12pt font write-up in your own words explaining the science behind your phenomenon.

RocketModeler was developed at the NASA Glenn Research Center in an effort to foster hands-on, inquiry-based learning in science and math. RocketModeler is a simulator that models the design and flight of a model rocket. The program works in two modes: Design Mode or Flight Mode. In the Design Mode, you can change design variables including the size of the rocket body, the fins, and the nose cone. You can also select different materials for each component. You can select from a variety of standard solid rocket engines. The program computes the center of gravity and pressure for your rocket and determines the stability. When you have a design that you like, you can switch to the Flight Mode (shown below), where you can launch your rocket and observe its flight trajectory. You can pause at any time to record data and then continue the flight through parachute deploy and recovery. This program has recently (Oct 8, 2004) been upgraded to support stomp rockets, bottle rockets, and ballistic shells in addition to solid model rockets. It also supports both English and metric units.

Add different salts to water, then watch them dissolve and achieve a dynamic equilibrium with solid precipitate. Compare the number of ions in solution for highly soluble NaCl to other slightly soluble salts. Relate the charges on ions to the number of ions in the formula of a salt. Calculate Ksp values.

PHYSICAL SCIENCE, EARTH AND SPACE SCIENCE The world's energy supplies are in crisis, and it's up to you to save the world! This game will teach you all about different power sources, alternative energy, and how we generate electricity to power our lives.
ABOUT THE SCIENCE So far, most of the world’s energy comes from non-renewable resources such as fossil fuels, oil and natural gas, but alternatives that can be replenished are constantly being developed and harnessed. These alternative energies use renewable resources like sunlight, wind, rain, tides and heat from the Earth to produce energy. Developing alternative energy sources is critical for sustaining the world’s energy consumption in the future. Wind, tidal, geothermal and hydropower are used to run turbines converting mechanical energy into electrical energy through a generator. Wind is the bulk air movement created by the variable heating of the Earth’s surface by the Sun. A wind turbine has three very large blades that are shaped like airplane wings to capture the mechanical energy from the movement of the air and convert it into a rotational force. A generator then takes the rotational force and transforms it into electrical energy. Tidal turbines function under the same principles as a wind turbine, but instead of capturing air movement, it captures water currents. Water currents are produced by a number of factors that include tides, variable temperature, winds across the ocean’s surface, and the Earth’s rotational movement. Geothermal energy uses energy in the Earth’s crust to heat water and produce steam that then drives a turbine. With the current consumption of energy the non-renewable resources like coal, oil and natural gas will eventually be depleted and alternative energy is needed in order to take their place and ensure lights can still turn on and houses are still heated. Hydroelectric generators convert the kinetic energy of moving water into electrical energy. Solar energy uses the Sun and material capable of absorbing light to create electricity from light in solar cells (photovoltaic cells), which can be connected in a series to create solar panels. The energy harnessed is then converted directly to electricity

PHYSICAL SCIENCE, EARTH AND SPACE SCIENCE Use what you learn about solar energy to save the school dance from vampires in this super cool solar energy game. Collect energy during the day using solar panels to ward off the vampires at night. Consider sun angle, tilt, shadows and time of year to maximize your energy collection - good luck!
ABOUT THE SCIENCE Did you know only absorbed light can be converted to electricity? What ways can you use the electricity that is converted from solar panels? Using solar energy in your home or business has a lot of benefits: it is free, clean, and infinitely renewable. It also reduces utility costs, increases energy self-reliance, and is extremely reliable. So, how does it work? Solar energy uses the direct conversion of light into electricity at the atomic level (photovoltaic cells) to generate electricity from solar energy and this process is called the photoelectric effect. Materials absorb photons of light and release electrons. When electrons are captured, an electric current results that can be used as electricity in our homes. Before we get the electricity in our homes, there are a variety of factors that need to be considered with solar energy: solar altitude or height of the sun and the angle throughout the day, and keeping solar panels shadow free are just a few.

In this project, students will use knowledge of electricity and electromagnetism to collaboratively design and test a model of a magnetic recycling sorter. They will evaluate the performance of their models and propose further modifications based on the output of their magnetic device measured in mT using a Vernier probe. They will also physically test their magnets on a model of a conveyor belt containing recyclable items. Students will track their data from both tests, with the ultimate goal of creating the strongest and most effective magnet with given materials. Finally, students will present their findings and proposed final design to peers and community partners involved in the recycling industry. The entire process takes about 6 weeks. The unit is a great fit for standards within energy and engineering & design.
