Students record hourly reading for water height for 24 hours and determine whether a location experiences diurnal, semi-diurnal or mixed tides. Links are present for the information. Students predict high and low tide, and answer a set...

Students research about how lunar cycles affect living organisms. In this biology lesson, students prepare an oral presentation of their research results and analyses. They explore the forces that affect tides.

Students describe how wedge and lever makes work easier. For this physics lesson, students analyze experimental data by creating a graph to see the trends. They calculate the work done and mechanical advantage of these simple machines.

Young scholars use computer images to explain why the Earth has seasons and examine the phases of the moon. They create 3-D images and present them to the class. They answer a series of questions at the end of the lesson.

Students research the Earth's patterns of rotation and revolution, create a chart and graph of these patterns and use them to explain the causes of night and day and summer and winter.
