Next Generation Science Standards
Next Generation Science Standards
- 4-PS3-2. Make observations to provide evidence that energy can be transferred from place to place by sound, light, heat, and electric currents.
- 4-PS3-4. Apply scientific ideas to design, test and refine a device that converts energy from one form to another.
- 3-5-ETS1-1. Define a simple design problem reflecting a need or a want that includes specified criteria for success and constraints on materials, time, or cost.
- 3-5-ETS1-2. Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem.
Featured Image Description
Circle of arrows the top light red arrow reads “Observation” in green. It points at the orange arrow with the text “Question” in blue. Which points to the bottom right yellow arrow which reads “Hypothesis” in purple. This points to the light green arrow with the dark red text “Experiment”, which points up to the light blue arrow with the dark orange text “Analysis”. This arrow points to the light purple arrow in the upper left of the image which has faded green text reading “conclusion”. This arrow points to the original light red “Observation” arrow completing and continuing the circle.
