Curated OER
Bacterial Transformation
Students explore DNA recombination. In this biology lesson, students observe the growth of microscopic species. They predict the phenotype of the transformed colonies.
Curated OER
Using the Hunter Model and the Holistic Model
Students increase their knowledge of scientific processes in chemistry. They compare and analyze 3 sets of data, they have gathered, for accuracy and precision.
Curated OER
Math Computation
Second graders complete math computation word problems. In this word problems lesson, 2nd graders read the math computation word problems and solve them.
Curated OER
Density Currents
Students experiment with currents caused by temperature variations that simulate the origins and flow of polar bottom currents. They discover water density is affected by temperature and salinity, resulting in deep water currents.
Curated OER
Number Sense Sampler
First graders read a variety of stories containing mathematical word problems. They illustrate the math problems with manipulable counters.
Curated OER
Number Sense Sampler
First graders illustrate a math problem with counters while reading story books, such as Margie Burton's "Add the Animals". They demonstrate a positive learning attitude toward mathematics and communicate clearly in oral, artistic,...
