Acid in the Water
Ninth graders learn about the effect pollution has on water and how this affects their community. In this environmental awareness lesson, 9th graders expand their vocabulary and create a flowchart that demonstrates the...
Curated OER
Solids and Liquids
Students complete activities to study the properties of solids and liquids. In this states of matter lesson, students investigate the melting and freezing of a range of materials in a virtual experiment. Students melt the substances and...
Curated OER
Threats to Validity
Students review the components of the scientific habits of mind. In groups, they use this information and relate it to scientific investigations. They develop strategies to evaluate information and evidence and how to question sources...
Curated OER
Friction
Students review what force. For this science lesson, students determine which surfaces are rough and which are smooth by observing how an object moves on each surface.
Curated OER
Reading Comprehension
Students review the task sheet and information on SQ3R reading strategy. They choose a text for reading then apply SQ3R to the text to preview and ask questions about the content, organizational structure and author's prupose for writing.
Curated OER
Distance Makes a Difference
Learners create a clay model of the Sun and Earth. In this space science lesson, students explain how distance affects the appearance of objects. They write a poem or riddle about the Sun in their journal.
