In this Dalton worksheet, students read about John Dalton and his contributions to understanding the atom. Students are given sample data for Dalton's experiments and they answer questions about the data in his experiments.

I don't trust atoms because they make up everything. Budding scientists learn about famous scientists connected to atomic models, chemical, ionic, and hydrogen bonds. The presentation also presents how to count atoms...

In this review for chemistry worksheet, students decide if given statements are true or false. Students relate information learned about introductory knowledge gained in chemistry to accurately answer the given questions.

In this atoms worksheet, students answer four different sets of questions related to atoms (fill in the blank, multiple choice, word puzzle and true and false).

Because of the work of John Dalton, we are able to write formulas for compounds. The hands-on experiment has scholars prepare a compound from its elements. Using mass data, individuals write the empirical formula for the compound.

In this static electricity worksheet, students complete nine questions about electron charges, coulombs, potential energy, voltage and the Van de Graaf generator.

In this electronics worksheet, students explore the properties of semiconductors to complete 17 short answer and problem solving questions.
