Earthquakes and Volcanoes Pre-Assessment
See how much your class knows about earthquakes and volcanic activity and how these events shape geologic features. The first lesson in the series of 20 is a pre-test to find out what pupils already know. It includes 10 vocabulary words...
University of California
Hot! Hot! Hot!
Calories are not tiny creatures that sew your clothes tighter every night, but what are they? A science activity, presented at multiple levels, has learners experiment with heat, heat transfer, and graph the function over time. It also...
University of Colorado
Modeling Sizes of Planets
The density of the huge planet of Saturn is 0.7 g/cm3, which means it could float in water! In the second part of 22, science pupils explore the size and order of the planets. They then calculate weight and/or gravity and density of...

Cosmic Microwave Background
Begin your next class with a BANG! Pupils discuss the formation of our universe and its expansion before proceeding with an activity designed to demonstrate what most likely occurred billions of years ago. They conclude with a discussion...
Curated OER
It's a Gas! Or is it?
Examine the effects of temperature and pressure on solubility and the states of matter of ocean water. Learners make inferences about the unique chemistry of ocean water at different depths. They engage in an activity related to...

Changing Sugar
In this chemical and physical change worksheet, students use a sugar cube and observe its physical properties both when it is whole and after it is crushed. They heat the sugar cube and record 5 properties of the matter while being...
Curated OER
What State Are You?
Students identify three states of matter and recognize plasma as fourth state. They provide examples of matter that are classified in particular state and identify properties of each state of matter.
Purdue University
Yucky Water? No Problem!
Young scholars study the process of water filtration in a three-part STEM lesson. After analyzing samples of dirty water, teams design and build their own filtration systems and measure their efficiency.
Curated OER
Atomic Models
Students explain scientists' ideas about the structure of the atom over the last century. They develop a pictorial history of the changing ideas about the atom and write a caption describing the scientific thinking behind the model.
Curated OER
Evidence of Chemical Change
In this chemical change worksheet, students conduct 4 experiments set up around the room. They follow the instructions at each station for each experiment and list the physical properties and observe any changes at each station. Students...
Curated OER
Solids, Liquids, and Gases
Students investigate and explore the three states of matter. They read and discuss the NASA article "The Engine That Does More," identify examples of each state of matter, and as a class complete a section of two worksheets. They...
Curated OER
Chemical Changes
Fourth graders examine and identify chemical and physical changes in a variety of substances. They observe a vinegar and baking soda demonstration, and a water, laundry detergent, and Epsom salt mixture demonstration. They discuss the...
Curated OER
Hot and Cold Colors
Young scholars examine how temperature effects changes in materials. In this physical science lesson, students use food coloring and cups of water of varying temperatures to observe the effects temperature has on matter. Young scholars...
Curated OER
Density Challenge
Students calculate the densities of several liquids that appear similar. In this physical science lesson, students go beyond understanding the way liquids of different densities behave to researching how this knowledge applies in real...
