I just recently got done completely a lab about physical and chemical, properties and changes. Warning, this lab was a large challenge for my freshmen students; I recommend that this lab be done for a full chemistry class. Student objectives: -Make accurate and detailed observations throughout the lab -Practice lab safety -Write connections between the background information and lab obser...

These last few days in class, I've been going over topics related to matter. Just to get the students into the idea of everything is matter, I use a density demo called "Does it sink or float?". I fill up a large plastic clear bin and fill it up half way with water, then pick up some random "safety" items to put into the water. During class, I ask the students what are all the ways we can describe...

I also tried the survey. The first question made me really think. But realized that the questions asked are questions that are common chemistry questions. They all related to water. It touched on how water has different physical properties compared to other materials. I would totally use the question about bubbles in a boiling container full of water. I predict that most students would say that ai...

4 Periodic Table Flashcards
This sciguide gives the reader a short and informative preview of what the topic is about. It also includes various real world examples that connect the scientific concept. For example talking about the change of property of frying an egg. Which then includes various already made simulations, articles and online activities. I would use the, online activities to have students practice being familiar with the periodic table, recognizing the chemical names, symbols and location of the element on the table. I would link the web resources to my developing class website. I would also use one of the atom websites, which includes a simulation of particle movement in an atom. I would like to see a resource that breaks down a real world example and explains or shows from larger visual size and moves into microscopic or molecules of the example. An average size egg, then (in a flow chart), the molecules that make up a yolk, then the atoms.
