NGSS Science and Engineering Practices. 4 – Analyzing and Interpreting Data. 3-5. Represent data in tables and/or various graphical displays (bar graphs, pictographs and/or pie charts) to reveal patterns that indicate relationships.
The shape and width of the tree’s growth rings often differ from year to year because of varying annual growth conditions
NGSS Crosscutting Concepts. 2 – Cause and Effect. 3-5. Cause and effect relationships are routinely identified, tested, and used to explain change.
Ask students to compare how much oxygen an “average” person needs with the amount an “average” tree produces.
Common Core. Math.3.OA.D.8. Solve two-step word problems using the four operations. Represent these problems using equations with a letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and estimation strategies including rounding.
Common Core. Math.4.OA.A.2. Multiply or divide to solve word problems involving multiplicative comparison, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem, distinguishing multiplicative comparison from additive comparison.
make a small “flip-it” book that shows photosynthesis in animation
NGSS Science and Engineering Practices. 2 – Developing and Using Models. 3-5. Develop a model using an analogy, example, or abstract representation to describe a scientific principle or design solution.
have students measure and graph their heights
NGSS Science and Engineering Practices. 5 – Using Mathematics and Computational Thinking. 3-5. Organize simple data sets to reveal patterns that suggest relationships.
digital pictures of their plants at different stages of growth to display with their measurements
NGSS Science and Engineering Practices. 8 – Obtaining, Evaluating, and Communicating Information. 3-5. Communicate scientific and/or technical information orally and/or in written formats, including various forms of media as well as tables, diagrams, and charts.
investigate to learn more about what plants need to grow
NGSS Science and Engineering Practices. 3 – Planning and Carrying Out Investigations. 3-5. Plan and 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.
Ask students what factors they think are necessary for plants to grow
NGSS Disciplinary Core Ideas. LS1.A – Structure and Function. 3-5. Plants and animals have both internal and external structures that serve various functions in growth, survival, behavior and reproduction.
Ask students what they understand about how plants make food energy
NGSS Disciplinary Core Ideas. LS2.A – Interdependent Relationships in Ecosystems. The food of almost any kind of animal can be traced back to plants. Organisms are related in food webs in which some animals eat plants for food and other animals eat the animals that eat plants. Some organisms, such as fungi and bacteria, break down dead organisms (both plants or plants parts and animals) and therefore operate as “decomposers.” Decomposition eventually restores (recycles) some materials back to the soil. Organisms can survive only in environments in which their particular needs are met. A healthy ecosystem is one in which multiple species of different types are each able to meet their needs in a relatively stable web of life. Newly introduced species can damage the balance of an ecosystem.
Ask students how the food web model might illustrate what happens when one of the links in an ecosystem is harmed through natural or human causes
NGSS Science and Engineering Practices. 2 – Developing and Using Models. 3-5. Develop and/or use models to describe and /or predict phenomena.
