Students share hypotheses about the variables needed to produce a collision between two moving objects. They simulate the impact of a moving object on an object that creates a spray of debris, and simulate a NASA Deep Impact study.

Students explore two-step linear equations.  In this middle school Pre-algebra lesson, students create and solve equations that describe how a person got to an end postion on a ruler by jumping.  After physically creating the...

Students examine Iraqi polls concerning the quality of life in their country. After exploring methodologies of taking polls and surveys, the compare and contrast the findings of two surveys. Students develop research questions,...

In this mixture worksheet, students fill two test tubes with water and add starch to one and salt to the other. They stir the solutions and observe their appearance. They answer four questions about their mixtures and determine if they...

Students participate in a two-week real-life math unit. In pairs, they calculate salaries, taxes, and a budget, plan a vacation, buy insurance, make a will, and design a room. They conduct Internet research to plan the vacation, and...

Students observe that plants need air, food, light, and water to survive.  In this plant biology lesson, students observe the growth and development of two plants, one is the control plant and the other is denied either air, water,...

Students analyze and record data. In this lesson about graphing and gathering data, students learn about the step of an experiment. Students learn new vocabulary, sort beans, record the data, and graph the data. Students add a variable...
