Classrooms around the world choose Daffodil and/or Tulip bulbs to plant during the same week in November. Students will be asked to collect temperature data throughout the experiment and report to the group – in addition they will report when the blooms appear etc.

CCSS Alignment for Grades 6-12

  • 6.RP.3: Use ratio and rate reasoning to solve real-world and mathematical problems, e.g., by reasoning about tables of equivalent ratios, tape diagrams, double number line diagrams, or equations. Students calculate ratios based on rate variables (sunlight, water, plant growth) and convert units between standard and imperial metrics (centimeters to inches, etc.).

  • 7.RP.1: Compute unit rates associated with ratios of fractions, including ratios of lengths, areas and other quantities measured in like or different units. Students can graph according to different combinations of variables and calculate rates with different lengths or in different units.

  • 8.EE.5: Graph proportional relationships, interpreting the unit rate as the slope of the graph. Compare two different proportional relationships represented in different ways. Students graph the results of their experiment and compare across group experiments to determine differences in variables.

  • A-CED.2. Create equations in two or more variables to represent relationships between quantities; graph equations on coordinate axes with labels and scales. Students will use different variables (sunlight or water for eample) to solve problems related to the optimal conditions for tulip or daffodil growth.
