Product Description
In one way or another, almost every form of energy we use originates as energy from the sun. Solar energy directly powers photovoltaic cells and thermal collectors. Indirectly, we get power from plants grown by the sun, oceans heated by the sun, and Earth’s weather systems sustained by the sun. Even the energy stored in fossil fuels originated as energy from the sun, captured by plants and animals millions of years ago. Physics Solar Workshop explores the topic of solar energy, focusing on photovoltaic cells. By building 12 models and conducting 30 experiments, you will learn how solar cells transform light into electrical energy, and how motors and mechanical devices can optimize the work done by this energy. You will build different types of vehicles and machines to demonstrate how gears can convert and transform power for different needs. There are 320 parts, which are also compatible with the other kits in our Physics line. The 64-page book offers illustrated instructions for the projects. Developed with Greenpeace® in Germany. Ages 8 and up.

| Customer Reviews: A functional science toy December 20, 2009 G. LAMB 11 out of 11 found this review helpful
When I read the sole review here, and then read very positive reviews at another site which also sells it, I was perplexed about whether to buy it or not. I bought it. Today, as a test I built the first solar vehicle in the booklet. It was late afternoon, with high clouds partly obscuring the sun when I took the solar car outside to see if it would work. The car did propel itself with just the solar cell and motor. It was not fast, but it did work. Inside, a flashlight provided more speed and vigor.
I will be interested in building the other experiments in the booklet with our grandson. I will also explain to him that we may have to add another solar cell or two to the solar car and see how much added speed that provides, but that will make it an even better science toy!
5 star product February 28, 2010 SantaBanta 4 out of 4 found this review helpful
we tried several items and the contraptions work flawlessly in sunlight. i need to find a good portable indoor source that can do the same so we can have some fun indoors.
i found this an extremely educational toy for my daughter and we both had a ball reading the instructions together and figuring out what to do.
-------------------
Update 3/14/10: After trying out a few more projects i feel they missed out on one main component that would enhance this kit. They should have included a polarity switch that allows the motor to spin in either direction (without having to manually swap the wires, as is required now). There are many projects that have limited motion in one direction (such as elevator, crane) and it would be nice to reverse the motor direction through a switch.
But still this is an awesome kit that sparks imagination.

Solar Cell and Motor is not powerful enough to run anything created December 7, 2009 Kabir 18 out of 19 found this review helpful
I bought this toy for my son's 10th birthday. He spent couple of hours creating the crane as instructed in the manual. The crane will not run in the sun or with a 100 Watt bulb. He tried to run it with one AA battery instead of the solar cell as written in the manual. It still will not run. If you just run the motor with the solar cell without any load on the motor, the motor runs with a 100 Watt bulb or in the sun. But as soon as you put any load on it, it stops running. I think 1.5 V motor just does not have any power to take any load. My son is extremely frustrated.
This is a very well designed product otherwise, with nice gears and other parts. The projects you can do with it like making cranes and vehicles are quite educational and fun to build. If they had provided a stronger motor and solar cell, this product would have been excellent and I would have given it a five star rating. But it is very frustrating when a product doesn't do what it is advertised to do.
