In this activity, students create a model using metric measuring tapes and atmosphere composition data. Students will investigate the major components of the atmosphere (nitrogen and oxygen) as well as the minor components which raise questions about global warming and greenhouse gases.
In this activity, students investigate and demonstrate chemical change by hollowing out the interior of a penny by dissolving the zinc inside with toilet bowl cleaner. This acitvity pairs well with the activity "Physical Change - Pennies."
In this activity, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages. This activity also introduces learners to greenhouse gases, infrared radiation, and global warming.
Students will repeat patterns in two and three dimensions to create tessellations. This activity combines the creativity of an art project with the challenge of solving a puzzle. This lesson features three investigations that are appropriate for varying grades and levels.
This website provides background information, data, historical records, hands-on activities, and graphics/media about earthquakes.
