All-in-One Home Drinking Water Test Kit. — — The Watersafe test kit contains everything you need to find out simply and accurately if your water contains unsafe or undesirable levels of 8 common contaminants. It’s easy as (1.) Open Watersafe Box (2.) Sample Water and (3.) Read Results! — The water kit tests for bacteria, lead, pesticides, nitrates/nitrites, chlorine, hardness and pH. Follow instructions carefully for each test and compare results to the Desired Values. Drinking water which tests outside the desired values may be dangerous to your health. — Watersafe is a screening test and cannot be used to certify water as safe or unsafe for drinking. Watersafe provides approximate results only when used in strict accordance with instructions. — Watersafe Water Test: EPA Standards, do-it-yourself, and results at home! — It can’t get any easier than this.
All in One Supplies for Testing a Variety of Water Elements — We worked with experts in environmental testing to create these kits, ideal for outdoor field work and science fair projects. Using your own tap water, well water, local pond or river water samples, you and your child can test for a variety of chemical elements and environmental factors. — Everything you need all in one convenient package, each kit comes with materials to complete ten tests and instructions.
Professional water-testing laboratories use the titration methods on which these test kits are based. — Compact, easy-to-use, reliable and accurate, these kits also provide results more quickly than comparable systems. Safety features include reaction vessels with ported caps to prevent spills and dispenser bottles that increase the accuracy of measuring and counting during experiments. — The components of each kit can be used to perform approximately 110 tests. For easy use, the bottles are clearly labeled and displayed in order of usage. Please note: Ammonia, Chlorine, Phosphate, and Iron Test Kits use colorimetric, instead of titration, methods. — Includes: titration syringes, reaction vessels, compact storage trays, carrying case (except for Ammonia and Iron Test Kits) and Instructions.
Based on standard titration methods used in professional water testing labs, these kits feature safety caps designed to prevent spillage. — In addition, dispenser bottles increase the accuracy of measuring and counting during experiments. Each kit contains enough materials to perform approximately 110 tests. — Includes: NBS Standard reagents, titration syringes, reaction vessels, compact kit storage trays and instructions.
Perform four important water pollution experiments. — Test water samples for dissolved oxygen content, chlorides, phosphates, and water hardness. — All tests provide professional results. Includes all necessary apparatus and materials.
Just add water! — This kit has everything else you need to conduct a wide variety of experiments and amazing water tricks. — Fill up your wash tub or sink and dive in. From building your own submarine to molding boats out of clay, making pepper jump, and creating rain in a sponge, Water Splash provides hours of learning fun.
This plastic model rocket (with a mean ’50’s Sci-Fi/Retro look) can fly up to 100 feet using only water and air pressure as “rocket fuel”. Set comes complete with 8″ rocket, air pump and fuel feeder. Adult supervision is recommended. — Where’s the Science? — A water rocket employs a compressed gas to accelerate water through its nozzle as a means of propulsion. The water inside the motor is essentially stationary and is accelerated to the velocity at the nozzle expressed by Bernoulli’s equation: P = pV2(the two is squared).
Kranius is a two-wheeled robot that you can program to follow a certain path without a computer. It has an 8-bit micro-controller, keypad with 33 tactile buttons and can store up to 60 programmed steps and 30 FOR-NEXT loops. Contains 6 vision sensors (2 infared light sensors to detect obstructions and 4 floor light sensors to detect contrasts of light like the edge of a table). — Dr. OWIKIT says this robot is more than just fun. Assembling, building, and following instructions help develop fine motor skills and hand-eye coordination. The programmable feature rof this robot requires you to plan ahead, think systematically and logically, develop problem-solving skills, and be challenged to think creatively. — Easy to assemble, this robot makes a great entrant for robotic competitions, robotic workshops, after-school programs, special events, gifts, science enrichment camps, and classroom activities. Skill level: II.
