Through Thick or Thin!!!

Calories are not tiny creatures that sew your clothes tighter every night, but what are they? A science lesson, presented at multiple levels, has learners experiment with heat, heat transfer, and graph the function over time....

In this science worksheet, students examine the graph with elements in order to differentiate atomic mass and categorizing the content.

Sixth in a series of 36, this lesson focuses on gases and their behavior in given situations. Learners review the states of matter and then focus on gases, specifically learning Boyle's, Charles's, Avogadro's Laws, Dalton's, and Graham's...

Students investigate various aspects of the planet Mars. They examine a core sample that is simulated to make observations. Then compare the known sample with one that is unknown and differentiate between the two. Students hypothesize...

Students explore Ultraviolet detecting beads and conduct several investigations with them.  In this investigative lesson students participate in an experiment to see the harmful effects of UV light and discuss their findings. 

Students investigate plastics and learn they are giant molecules made of carbon atoms. In this polymers and plastics lesson, students perform 3 activities which all include making polymers from household items such as milk and vinegar,...

Students will examine the layers of the Earth. In this geology lesson, students create a scale model of the Earth's interior using cash register tape. They will determine the percentage of error in the scale compared to the actual size...

Students examine why humidity changes throughout the day. They study the concept of relative humidity, absolute humidity, and dew point temperature. They interpret phase diagrams and explain why relative humidity typically falls and...

Students examine sunspots. In this sunspot lesson, students use applets to investigate the movement of sunspots. Students research sunspots and evaluate the rotation of the sun. Lesson references outside resources not available in this...

Middle schoolers determine ways to make "observations" about unknowns, such as the land beneath an ice sheet or the interior of the Earth, using tools other than sight. They build "mystery boxes" and exchange them with other groups to...
