Curated OER
Solid Rocket Boosters
In this rocket activity, students calculate the burn rate for solid rocket boosters depending on exposed fuel area and burn depth. This activity has 2 problems to solve.
Curated OER
Project Geode
Students predict the appearance of a geode's internal structure based on its mass and density. They form a hypothesis based on the data they collect. They also identify common minerals found in Illinois.
Curated OER
Enzyme Grabbers
Learners perform simple experiments to show properties of enzymes through studying how apple sauce can turn into apple juice and experimenting with papaya seeds. Students witness how enzymes speed up reactions through witnessing the...
Curated OER
Ice Cream Blizzards
Fourth graders explore whether the making of homemade ice cream is a physical change or a chemical change in a lab experiment. Students identify states of matter, describe the physical properties of states, and collect temperature data...
Curated OER
Ice Cream Chemical and Physical Changes
Fourth graders identify characteristics of a simple physical and chemical change. They describe objects by the properties of the materials from which they are made and that these properties can be used separate. Students describe the...
Curated OER
What is the Mantle Like?
In these earth science worksheets student complete this project to model activity in the mantle, one Earth's four layers. The project includes liquid and powder materials in addition to several measuring components. Students must then...
Curated OER
Density: Float or Sink
Students discover density. In this density lesson, students discover the properties of objects that allow them to float or sink in water.
Curated OER
Causal Patterns in Density Phenomena
Students realize that density exists. They develop a mental model of density-to realize that something is going on that they cannot see to account for differences between materials.
Curated OER
Icebergs Ahead!
Students experiment with density of ice, and examine how density affects how icebergs float in water.
Curated OER
Measuring: Why Can't We All Just Get Along?
Students examine why having standardized units of measurement is important. They investigate the use of non-standard measure, twigs, while measuring the piece of tape. Next, they experiment with straws, paper clips, and rulers before...

THE TRAVELS OF BABAR: An Adventure in Scale :Building a Model Hot Air Balloon
Students encounter basic facts about helium and hot air. They compare the weight and size of different materials. Students work collaboratively in teams. They create their own model balloon.
