In this math and geography real world investigation, 6th graders plan a driving trip to a city that is located several states away from their home while recording the elevations of three cities that are included in the trip. They use...

Don't melt away! Pairs investigate different insulation materials to determine which one is better than the others. Using a low-temp heat plate, the teams insulate an ice cube from the heat source with a variety of substances. They...

Wave goodbye to the same old demonstrations for alternative energy sources, and wave hello to this one investigating ocean waves! Using a water bottle to create an oscillating water column, learners see and possibly hear how the...

In this geology worksheet, students investigate a sample piece of granite and describe the properties of granite in a 15 question chart.

In this investigations activity, students complete a hypothesis, variable manipulation, and more for sleeping habits, rolling wheels on a skate board, sports practice, and more.

Milk does a body good ... unless, of course, someone is lactose intolerant. Pupils play the role of pharmaceutical scientists in a guided inquiry lab about lactase. Lab groups collaborate to learn more about lactose intolerance, how...

In this math activity, students participate in an investigation of Smarties candy. For example, students estimate how many candies they have in each color, count the actual number, and record the information in a tally chart.

Rise and shine! Class members collaborate to construct a photovoltaic solar cell with two semiconductor layers, as guided by this fabulous lab sheet. They test its output with an ammeter or galvanometer. 

Take a look at acceleration within the context of automotive technology. They vary the mass on a toy car and run it down a ramp, exploring Newton's second law of motion. Though this is a classic lab activity, you will appreciate the...

In this Earth worksheet, middle schoolers investigate the interactions between the four major parts of the earth-the atmosphere, the geosphere, the biosphere and the hydrosphere. Students discuss their findings as a class.

What do plate tectonics and ocean currents have to do with global climate? This fourth installment in a six-part series focuses on how plate tectonics and ocean currents affect global climate, both now and in the past, outlines an...

Using helium as an example of propane, physical science middle schoolers experiment with and graph the relationship between temperature and volume in gases. In a whole-class demonstration, they show how molecules behave under different...
