If you have a set of six various metal rods, you can use this lab activity to challenge science students to calculate their densities. They will use a triple beam balance to measure the mass and the micrometer and ruler determine the...

Assist your middle school class with one of the most inclusive weathering and erosion labs available. Individuals use sugar cubes and alka-seltzer to demonstrate the process of physical and chemical weathering. They sketch results...

Mass and density — aren't they the same thing? This activity has groups use balance beams and water displacement to measure several objects. The pupils use the measurements to calculate the density of the objects. 

Groups suspend objects within layers of liquids to determine the densities of different liquids and compare them to the densities of objects calculated in Part 1. The groups then carefully test their calculations by layering the...

In this observing and identifying matter worksheet, middle schoolers use a cookie in a bag and list 10 different descriptions of the cookie. They draw and label their cookie and given the cookie in the bag to their teacher who mixes all...

In this Earth worksheet, students read about Earth's gravity, the reason the Earth has seasons, and time zones. Then students complete 21 multiple choice, 2 true or false, and 1 short answer question.
