Here is a unique assigment: compare and contrast ionic and covalent compounds in an extensive data table and then analyze Lewis dot structures in antoher. Three columns are to befilled in: "characteristic or feature," "applies to ionic...

Even middle schoolers still enjoy experimenting with bubbles! They execute a series of experiments enabling them to distinguish between convex and concave surfaces, explore the properties of buoyancy, surface tension, and density,...

Young scholars use principles of geometry to measure the circumference of the Earth. In this applied geometry lesson, students use mathematics to determine scientific information. They make measurements, calculate the central angle,...

Fourth graders participate in a variety of activities dealing with animal characteristics and classifications in this multi-task lesson. They use graphic organizers, make booklets, and make models.

Students explore how an archaeologist works and makes discoveries. In this archaeology lesson, students participate in a simulation in which they excavate broken pottery. Students use measurement, geometry, and observation skills during...

Students study parallax and what it is used for.  In this distance lesson students complete an activity that allows students to get experience using a parallax.

Middle-schoolers still enjoy playing with bubbles! In this series of eight laboratory activities, science learners explore convex and concave surfaces, angles, gas laws, buoyancy, density and more! 

Very deep presentation of molecular bonding and orbital theory. Nice graphics and text make it a good presentation of some high end material.
