ALTERNATIVE ENERGYPhoton Solar RacerPhoton Solar Racers can be built in one class period and raced in another. Assembly requires only scissors and a small screwdriver. Models demonstrate sensitivity of car speed with slight sunlight variations, and achieving very fast speeds in bright sunlight. After building the initial models, students manip-ulate key solar/mechanical components to design and power other cars with various chassis designs to race against each other.AP6060 I $33.50Solar-Powered Cars—Flinn STEM Design Challenge™After learning how a solar car works, students build solar vehicles using mini solar panels that convert the Sun’s energy to electricity, then investigate variables and their effects on the car’s performance. Based on data and observations, students create an optimal design solution for a faster car. Student enthusiasm and ownership increase as they apply knowledge and reasoning skills in this engineering design process.AP8049 I $149.95Cooking with Solar Energy—Flinn STEM Design Challenge™Learn how use the Sun’s ultraviolet radiation to cook food with no electricity or flames in a solar oven. Students make a basic box-type solar oven and then investigate how high the internal temperature reaches in an amount of time. After collecting and analyzing data, students apply their knowledge of heat transfer, reflection, absorption and the greenhouse effect in design-ing improvements for a more efficient oven.AP8048 I $51.20Alternative Energy—Flinn STEM Design Challenge™ 5-Kit BundleCost-saving bundle includes 5 Flinn STEM Design Challenge™ Alternative Energy kits to help students make connections between renewable energy concepts and engineering design. Kits include Cooking with Solar Energy, Solar-Powered Cars, Build a Water Wheel, Generating Electricity with Wind and Biofuels. See other listings and flinnsci.com for details.AP8085 I $322.80Generating Electricity with Wind—Flinn STEM Design Challenge™Students investigate how the blade design of a wind turbine affects the power it gener-ates by building a rotor and blade assembly from provided materials then testing it with a DC motor connected to a multimeter. A fan provides wind. Students record highest volt and amp readings and calculate the maximum power output. After observating and analyzing preliminary data, students work to enhance their designs and test them for electrical output.AP8051 I $48.95Mini Solar PanelsDesign your own solar energy experiments with these durable, mini solar panels. Encapsulated in plastic cases, they will stand up to repeated student use. Connect to vari-ous devices with 6” lead wires. Each panel measures 3¾” L x 2½” W. Available in 1.5 (200 mA), 3 (100 mA) and 6 V (50 mA).CATALOG NO.DESCRIPTIONPRICE/EACHAP79001.5 V, 200 mA$14.60AP79023 V, 100 mA17.20AP79036 V, 50 mA20.501,000+ PHYSICS & PHYSICAL SCIENCE PRODUCTS @flinnsci.com
