Trophic Relationships, Cycling of Chemicals, Human Impact on Ecosystems and Conservation
Students explore how the energy flow through a system is related to trophic levels. They investigate how organisms affect the cycling of elements and water through the biosphere. Students participate in lab activities to observe ways...
Curated OER
Where in the World is Carbon Dixoide?
Students conduct experiments designed to detect the presence of CO2 by using a BTB that changes color (blue to yellow) in the presence of CO2. First, students experiment with the CO2 from combining vinegar and baking soda. In part two,...
Curated OER
Buoyant Force
Students investigate the scientific concept of why some objects float when put in a liquid solution. They apply the laws of motion and force while conducting classroom activities. Students also take notes and answer target questions to...
Curated OER
Discovering Physical Changes
Fourth graders determine what is meant by a physical change, and they demonstrate how they can make physical changes. They complete activities at stations that entail changes in color, size, texture, hardness, or state of matter. Using...
Curated OER
Habitat Cards
Students discuss the relationship between a habitat and the environment. In groups, they use the internet to research the relationship between the animals and the habitat on their card. They present their information to the class to...

Living During the Little Ice Age
Students brainstorm what living conditions during the period known as the Little Ice Age (1350-1850) might have been like. They research lifestyles, the economy, crop yields, and human and livestock mortality.
Curated OER
Where Have All the Glaciers Gone?
Fourth graders discover that scientists examine evidence from around the world in order to explain global climate change. They see that records of climate change exist, and describe photographs interpreting changes in glaciers over time.
