Technology & computer science
Binary Numbers: Counting with Only 0 and 1
Students convert between binary and decimal using a place-value chart, decode a secret word, and add two binary numbers.
Science
Build the Atom: Protons, Neutrons, Electrons and Isotopes
Students use atomic number and mass number to find particle counts for atoms and ions, then calculate an average atomic mass from isotope data.
Study skills & advisory
Catalog Entries and Call Numbers: Find It on the Shelf
Students read made-up library catalog entries, use the general Dewey ranges to predict where books belong, and practice putting call numbers in shelf order.
Mathematics
Complex Numbers: The Cycle of i and Complex Arithmetic
Students discover the repeating pattern of powers of i, then add, subtract, multiply and divide complex numbers.
Science
Energy Forms and Transfers: Follow the Energy
Students read about energy forms and conservation, trace energy transfers in six devices, and calculate wasted energy and efficiency.
Mathematics
Exponent Rules and Scientific Notation Workshop
Students apply exponent rules, convert between standard and scientific notation, multiply in scientific notation and solve a travel-time problem.
Science
Gas Laws by the Numbers: Pressure, Volume and Temperature
Students apply Boyle’s, Charles’s, Gay-Lussac’s and ideal gas relationships to numerical problems and explain which direction each variable moves.
