Making Models of Atoms and Isotopes
In this models of atoms and isotopes worksheet, students use marshmallow of different colors to represent the protons, neutrons and electrons in an atom. Students make models of the 3 isotopes of hydrogen. They draw a diagram of each and...

Chapter 7 Practice Problems
In this space science worksheet, students identify ultraviolet beams and what occurs when the frequency is doubled. They identify how long it would take to send a radio message from a space probe of Mars to earth. Students also determine...
Curated OER
Atom and Eve
Students research and define an atom using a concept map. They design and create a model of an atom, labelling all the parts, and write a journal entry.
