Students investigate time. In this investigative instructional activity, students run through an obstacle course using standard timers. They record the time and apply this knowledge to problems in math. Students record their predictions,...

Students make a sundial. In this time instructional activity, students determine the time of the day by creating a sundial. They check the time on the sundial, hourly, for one week. Afterward, they explore what happened to the shadows in...

Students explore the evolution of time measurement, and explain the relationship of sunrise/sunset to length of daylight. They collect data and calculations to determine length of daylight during a given day.

Students construct clocks and then learn how to read a clock face, tell time, and determine how much time has elapsed.

Students calculate elapsed time and look for patterns.

Students gather data, make and share predictions about the time of sunrise ans sunset in their area. Patterns are analyzed and shared with students from other areas.

Students study the laws of reflection using light beams and mirrors. In this reflection lesson, students work in teams to direct light beams to targets around the classroom. Students use mirrors to change the beam's path and compete...

Students investigate the effect of day length on animal migrations. They view a Powerpoint presentation, identify their own personal migrations and cues, answer discussion questions, and test a hypothesis about seasons.

For this sunspots worksheet, students observe two images taken by a solar observatory over a certain amount of time. Students determine the changes in the pictures and then calculate how fast and in what direction the particles are...

Seventh graders investigate scientific methods to solve problems. They demonstrate creating data tables and graphs. They study the role of a scientist and the importance of safety in a science lab. They distinguish between an...
