Under what conditions will the flame strike back? With too little air, the gas mixture will not burn completely and will form tiny carbon particles that are heated to glowing, making the flame luminous. With too much air, the flame may burn inside the burner tube; that is, it may strike back. How do you […]

What are the 5 science processes?
What are the 5 science processes? SCIENCE BEGINS WITH OBSERVATION We observe objects and events using all our five senses, and this is how we learn about the world around us. The ability to make good observations is also essential to the development of the other science process skills: communicating, classifying, measuring, inferring, and predicting. […]

What if we lived in a star cluster?
What if we lived in a star cluster? Inside a globular cluster, there might not be enough building materials for a rocky planet like Earth to be formed. Even our Sun might have had trouble forming in those conditions. Binary star systems aren’t unusual in the Universe, but they are less likely to host habitable […]
