Science teachers are often faced with the difficult task of trying to use scientific issues are complex and abstract concepts for students who are often bored or uninterested to teach. Students usually have many other questions in mind during the lesson, love interests, problems with friends, or what kind of fun on the weekend as will bring.
To break through this wall of indifference, the science teacher to take a creative approach to scientific questions that are both instructive and entertaining.
Funny Bone to detect and catch their Minds
The only way to attract the interest of students who are indifferent to science, especially a high school student feels grasp, through the presentation of scientific questions about things related to common objects or events of everyday life. The following questions are so trivial that they are the students in the wall trying to do to find the right answers. Use it to encourage lively discussion of the science questions in class and to generate interest in science among students.
What makes popcorn pop?
Everyone loves to eat popcorn, but few people really appreciate the science involved in the process of popcorn. Although it is known that the kernel of popcorn is a seed, it’s what’s inside that seed is often a mystery. The center of the core is an embryonic planet by a very soft material made from starch and water, surrounded. To this inner core is the hard shell of the seed. Heating of the core at a fire or in the microwave, eventually causes the core temperature to 400 degrees Fahrenheit meet. At this point, the point of vaporization of water is reached, and it turns into steam. The vapor pressure causes the rupture of starch and water mixture through the outer shell – and you tasty popcorn!
Why drop the metal, but boats float?
This question is a great teaching the principles of density. A steel rod will certainly go down in the water because it is much denser than water. Because of the U-shaped design of a boat, the “inside” of the boat is actually mostly air. The air inside the boat makes the whole boat is much less dense than the surrounding water. Any object that floats on a liquid of lower density and higher density. That’s why people increases (or water) into the boat, its density and the boat is sinking further into the water. If the boat in tight (filled with water), will begin to sink it under water.
Why do leaves change color in autumn?
A big question for kids teach about plant biology is to discuss what happens to leaves in autumn. In fact, many adults do not realize that these colors were on the leaves all summer. The green color comes from the process of photosynthesis, trees, their use throughout the spring and autumn to produce food and energy from the sun. The tree produces chlorophyll, a green dye, which allows the photosynthesis. But in the case where this process ends, and the trees begin their “hibernation” phase. Because photosynthesis is no longer current does not produce chlorophyll, and come out the true colors of the leaves.
Ask the students to ask questions
Even better than the students ask these questions is that students’ questions about things that they never really ask before thought. Ask them to try to scientific questions about things in everyday life, the answer to no one else in the class (sometimes even the teachers!) Can generate enough questions for everyone in the class or group will find 2 or 3, and assign the task, the answers via the Internet or your local library.
