Planning and Carrying Out Investigations
Planning and carrying out investigations to answer questions or test solutions to problems in 3–5 builds on K–2 experiences and progresses to include investigations that control variables and provide evidence to support explanations or design solutions.
Conduct an investigation collaboratively to produce data to serve as the basis for evidence, using fair tests in which variables are controlled and the number of trials considered. (5-PS1-4)
When two or more different substances are mixed, a new substance with different properties may be formed. (5-PS1-4)
Cause and Effect
Cause and effect relationships are routinely identified and used to explain change. (5-PS1-4)

This is a two part review of a 10-day module in which students work on several mini-design challenges that culminate in a multi-day engineering design challenge. In the first 6 modules, students focus on Structure and Properties of Matter t ...
In this engineering design challenge, students use their knowledge of science to help design and build a vehicle that is powered solely by a chemical reaction. First, they figure out the most effective combination of substances and water to create a ...
Students observe the mixture of yeast, dish soap, and hydrogen peroxide, creating a irreversible chemical change known as “elephant toothpaste.” Students then plan and conduct an investigation to determine how changes to the mixture ...
This lesson invites students to plan an investigation and use their collective knowledge to identify individual substances in a “mystery mix.”
The resource includes a story that provides context and relevance for st ...
Students investigate and describe multiple indicators of both physical and chemical changes over a 10 day unit. The learning opportunities students were provided specifically addressed misconceptions about the reversibility of changes and the co ...
In this set of learning experiences arranged in a the linear 5 E lesson format, students will perform a series of investigations to further their understanding of the structures and properties of matter;and more specifically, what happens to matter w ...
