Science ConnectionThink Likea ScientistBy David CochranHave you ever thought about how you think? Have you ever wondered how wecan look at something that is confusing and make sense out of it? Scientists dothis all the time. Learning how scientists think can help us become betterthinkers. The scientific inquiry process is an important part of discovering andlearning how the world works. When reading Spigot, look for opportunities toThink Like a Scientist.Thinking and Acting SafelyScientists are always thinking of new ways to developtheir ideas, but that’s not the only thing theyare thinking about. As they conduct their investigations,scientists realize that these experiments can bevery dangerous. They are also thinking about safetyprecautions to avoid injury.Safety should also be on the minds of teacherswhen students do science labs. This is especially trueif the labs involve the use of electrical equipment.Electricity can be very dangerous, so we all need totake steps to avoid injury. .Here are some common safety tips related to theuse of electricity. Many of these can apply to ourhomes as well as a science lab:1. We always need to be on guard when usingelectricity. If we touch live wires, we could becomepart of the electrical circuit and suffer a shock.2. We need to watch out for electrical cords.Cords should be placed carefully so people don’t tripon them.3. When handling electricity, we should makesure we have dry hands. Water is a conductor ofelectricity and current can jump from wires to wetsurfaces so we should use electrical equipment in adry area.4. Many labs have rubber mats to stand on whenworking with electricity. Rubber helps to insulate,or ground, us from electric shock.5. We need to avoid touching electrical outletswith our hands or a conducting metal material suchas a knife.6. Plugs, wires, and appliances should be in goodworking condition. If wires are frayed or plugs haveburn marks on them, we should not use them.7. We need to know the type of electricity we arenear. Is it a battery? A wire with high amperage?8. It is a good idea to inspect the electrical equipmenteach time we use it to avoid problems.9. If someone is in contact with a live electricalconductor, we should never touch the person, theequipment, or the cord. It is safer to call for help andfind a way to turn off the electricity.10. Perhaps the most important rule is to alwaysbe aware of the area where electricity is used. Bybeing aware and thinking safety all the time, we canavoid most accidents.Some of these safety measures may seem likecommon sense, but they are all important to scientistsand to us. As we think like a scientist, weshould also think of safety first.Discussion1. Have you seen what can happen when electricityis not used safely? What happened?2. Why is safety so important when workingwith electricity?3. Why is it important to think about safety first?Spigot Science - http://www.spigotscience.com 14 Electricity
