Hydropower has been used for hundreds of years in watermills and is now commonly used to generate electricity in applications such as hydroelectric dreams and Tidal power plants. Explore the power of water by building models and conducting experiments with them. Learn about how different devices are used to extract useful energy from moving water — from a waterwheel in a small stream to a giant turbine in a Tidal power station. Build a waterwheel, a sawmill, and a hammer mill to harness the energy of moving water to do different types of physical work. Investigate the intriguing properties of water by performing experiments involving surface tension, adhesion, and cohesion. Learn about water pressure by building a water tower, communicating vessels, and a water fountain. Construct a hydroelectric power station to generate electricity and light an LED. Learn about where the energy in ocean waves, tides, and rivers comes from, and discover how we can generate electricity from them.

BACKGROUND INFORMATION: LB stands for Luria Broth, a nutritionally rich medium, which is one of the most common media used in the laboratories worldwide. LB medium is recommended safe for student use, whereas Tryptic Soy Agar medium is NOT suitable for student use due to its ability to amplify blood-borne pathogenic bacteria.
1) 10x Pre-poured sterile LB-agar plates (100 x 15 mm Petri Dish) 2) 10x 6-inch sterile cotton swabs (2 per pouch) 3) Detailed Instruction 4) Free Science Fair Project E-Book LB agar plates should be placed in a refrigerator upon arrival. LB-agar plates stored under such conditions have a minimum shelf life of 3 months.
BRIEF INSTRUCTION: 1) Take out one sterile cotton swab. Gently wipe a test area with the cotton swab to pick up bacteria. Here are some of the popular samples of the test objects: human or pet teeth, hands, phone, TV remote, restaurant menu, sink, floor, fruit, vegetable etc. 2) Take out one of the agar plates (No warm-up is needed). Open the agar plate and gently streak the agar plate with the cotton swab to transfer the bacteria onto the surface of the agar plate. 3) Cover the agar plate and place it in an upside-down position in an incubator with a temperature between 85 and 100 oF. A desk lamp or a portable heater can be used as a heat source. 4) Watch appearance of small bacterial colonies on the surface of the agar plates after 12-48 hr of incubation.
LIVE TECHNICAL SUPPORT: EZ Prepoured LB agar plates are backed by our 100% money back guarantee. If more technical assistance is needed, we not only provide you with an email address but also a telephone number to talk to our friendly laboratory tech support.
THE #1 BEST SELLING BACTERIA SCIENCE KIT ON AMAZON: Professional quality products and services at unbeatable prices! Lots of science fair competition awards! We offer 100% money back guarantee.
THE SAFEST AGAR PLATES ON AMAZON: Luria Broth(LB) agar plates are used to grow environmental bacteria. By contrast, Tryptic Soy(TS) agar plates are used to grow pathogenic bacteria from clinic patients. TS agar plates will grow blood-borne bacteria which are very dangerous in unprotected environments such as home and school. The amplified blood-borne bacteria could infect other family members, students and teachers. Be aware of the hidden health risk when using TS agar plates!
BIOTECH QUALITY, FRESH AND READY-TO-USE: Factory-direct fresh 10 100-mm Pre-poured sterile LB-agar plates and 10 sterile 6-inch long swabs (in 5 pouches). Our plates are manufactured using the biotech GMP standards. Each plate has a fresh and thick layer of agar. Fresh plates promote faster and more bacterial growth as compared to aged stored plates. Re-sealable packaging convenient for re-use.
FREE SCIENCE FAIR PROJECT E-BOOK: Packed with easy-to-do experiments with clear step-by-step instruction to help you winning science fair competition. Experiments range from testing simple 5 second rule to evaluating the effectiveness of inhibition agents. Tips and advices are provided to avoid common mistakes.
