1st Grade Activities | Posted in Early Childhood
Hello Kristina. In Texas children learn about clouds in first grade. I saw an activity that used shaving cream in a jar to represent the different types of clouds. I also think you need food coloring. You can find the exact materials on Pinterest. Basically it is a hands on way to provide students with a visual of various clouds. Also shaving cream is usually inexpensive. Another option is to teach moon phases with oreo cookies. Not sure what you are looking for but I hope that helps. I always check pinterest for fun ideas.
Science Trips | Posted in Informal Science
There was a great science field trip that I got to observe in my students teaming called Days of Taste. It was a three day process that followed the process of a well-designed experiment and combined the subject of health and good eating all in one! A nearby farm partnered with the school to come to the school the first day and introduce the topic while giving the students different types of demonstration powders to get their taste buds flowing and practice prediction and data collections. The second day the kids went to the farm to see the process of making milk and cheese and harvesting the crops that they are growing. The third and final day, the farm comes back to the classroom alongside of a local restaurant that benefits and works with the farm to finish the investigation process and confirm or reject hypothesis. Then they get to use the foods that they learned about to create a salad that would be the best fit for your health. The combination of incorporating science, health and arts with they creation and display process works out great for the students learning benefits!
The Drake Equation | Posted in Earth and Space Science
The Drake equation is not directly used by scientists in their research. Rather it is often used when talking about life in the universe to non-scientists, such as in astrobiology courses, as James mentioned. One of the keynote addresses I sometimes deliver is on astrobiology, and I discuss the Drake equation quite a lot, as it relates to many fascinating topics regarding the development of life in the universe, where we would expect to find life, and how common we might expect life to be.
The purpose of the Drake equation is not to give a precise answer to that fundamental question -- How many technological civilizations are in our galaxy? -- but to form the basis of discussions by presenting various types of information that we would need to know, if we wanted to answer that question.
So basically the Drake equation is a statement that "stimulates intellectual curiosity about the universe around us, for helping us to understand that life as we know it is the end product of a natural, cosmic evolution, and for helping us realize how much we are a part of that universe." (https://www.seti.org/drakeequation)
What the equation and the search for life has done is focus science on some of the issues concerning life in the universe, specifically the development of life starting with chemical processes, the development of multi-cellular life, and the development of intelligence.
