In this activity, participants learn about the hydrosphere by making observations and taking measurements. They will go outside and use scientific equipment to investigate temperature, pH and transparency of a body of water. They will use this... (View More)

This is a lesson about crystal growth. Leaners will grow a sugar crystal and learn how this relates to growing protein crystals in space. The lack of gravity allows scientists on the space station to grow big, almost perfect crystals, which are used... (View More)

In this lesson, students explore a discrepant event when they design an experiment to measure the rate that ice melts when in pure water versus salt water. It is designed to help students realize that a carefully-designed experiment may yield... (View More)

This is a lesson about density. Learners will relate the concept of density to the density of dust in space. They will use mission data from the Student Dust Counter (SDC) interface to determine the density of dust grains in a volume of space in the... (View More)

In this lesson, students will explore the density of substances as a model for understanding the mass to light ratio as a predictor of dark matter. They will measure and calculate mass and volume to calculate the density of a foam ball. Students... (View More)

This is a set of materials about spectroscopy, including a downloadable PowerPoint presentation and two demonstrations or activities. Learners will read and/or hear about the science of spectroscopy, what a spectrum is, and how spectroscopy is... (View More)

This is a set of materials about spectroscopy, including a downloadable PowerPoint presentation and other related resources. Learners will read and/or hear about the science of spectroscopy, what a spectrum is, and how spectroscopy is important to... (View More)

In this activity, students will discover how mass is distributed in the solar system and a galaxy by using kitty litter. Students compare the distribution of mass in a solar system to the distribution of mass in a galaxy. This is Activity 6a in the... (View More)

This is an activity about the correlation between annual precipitation and plant productivity in different Earth biomes. Learners consider water evaporation, solubility and abundance relative to life on Earth and relative to finding evidence for... (View More)

This lesson plan focuses on the concepts of atomic number, mass number, isotope, and nuclear atom. A student quiz is included as an assessment instrument. This resource is from PUMAS - Practical Uses of Math and Science - a collection of brief... (View More)
