Notes for teachers

  • This lesson takes place in a garden or area for an hour each day for seven weeks.
  • Depending on the place and season, you will be growing different plants. Feel free to look at additional references: https://extension.arizona.edu/sites/extension.arizona.edu/files/pubs/az1005-2018.pdf
  • Students may work in small groups of 2 per space.
  • Create an emphasis on utilizing resources around us to solve problems, and what can be repurposed.
  • Creative solutions should be encouraged and discussed.
  • Be aware of the notes section at the end of each day, there are some activities you will need to prepare for in the coming weeks.
  • To make it easier for supplies: Pencil Box-one per four-pencils, crayons, colored pencils, markers, scissors, glue

Science Standards

4.E1U3.9 Construct and support an evidence-based argument about the availability of water and its impact on life.

4.L4U1.11 Analyze and interpret environmental data to demonstrate that species either adapt and survive or go extinct over time. ● When the environment changes in ways that affect a place’s physical characteristics, temperature, or availability of resources, some organisms survive and reproduce, others move to new locations, yet others move into the transformed environment, and some die. ● Fossils provide evidence about the types of organisms that lived long ago and also about the nature of their environments. ● For any particular environment, some kinds of organisms survive well, some survive less well, and some cannot survive at all.

S/L Standards

4.SL.1 Engage effectively in a range of collaborative discussions (one-on-one, in groups, and teacher-led) with diverse partners on grade 4 topics and texts, building on others’ ideas and expressing their own clearly. a. Come to discussions prepared having read or studied required material; explicitly draw on that preparation and other information known about the topic to explore ideas under discussion. b. Follow agreed-upon rules for discussions and carry out assigned roles. c. Pose and respond to specific questions to clarify or follow up on information, and make comments that contribute to the discussion and link to the remarks of others. d. Review the key ideas expressed and explain their own ideas and understanding based on the discussion.

4.L.2 Demonstrate command of the conventions of Standard English capitalization, punctuation, and spelling when writing.

4.RL.3 Use knowledge of language and its conventions when writing, speaking, reading, or listening.

4.RL. 6 Acquire and accurately use grade-appropriate general academic and domain-specific words and phrases, including those that signal precise actions, emotions, or states of being (e.g., quizzed, whined, stammered) and that are basic to a particular topic (e.g., wildlife, conservation, and endangered when discussing animal preservation).

● Obtain, evaluate, and communicate information

Mathematical Practices

4.MP.1-Make sense of problems and persevere in solving them.

4.MP.2-Reason abstractly and quantitatively.

4.MP.3-Construct viable arguments and critique the reasoning of others.

4.MP.4-Model with mathematics.

4.MP.5-Use appropriate tools strategically.

4.MP.6-Attend to precision.

4.MP.7-Look for and make use of structure.

4.MP.8-Look for and express regularity in repeated reasoning.

8 of 59

ELA Standards

4.RI.6. Compare and contrast a firsthand and secondhand account of the same event or topic; describe the differences in focus, and the information provided.

4.RI.7 Interpret information presented visually, orally, or quantitatively (e.g., in charts, graphs, diagrams, time lines, animations, or interactive elements on Web pages) and explain how the information contributes to an understanding of the text in which it appears.

4.W.3 Write narratives to develop real or imagined experiences or events using effective technique, descriptive details, and clear event sequences. a. Orient the reader by establishing a situation and introducing a narrator and/or characters; organize an event sequence that unfolds naturally. b. Use dialogue and description to develop experiences and events or show the responses of characters to situations. c. Use a variety of transitional words and phrases to manage the sequence of events. d. Use concrete words and phrases and sensory details to convey experiences and events precisely. e. Provide a conclusion that follows from the narrated experiences or events.

Math Standards

4.MD.A.1 Know relative sizes of measurement units within one system of units which could include km, m, cm; kg, g; lb, oz.; l, ml; hr, min, sec. Within a single system of measurement, express measurements in a larger unit in terms of a smaller unit and in a smaller unit in terms of a larger unit.

4.MD.A.3 Apply the area and perimeter formulas for rectangles in mathematical problems and problems in real-world contexts including problems with unknown side lengths.

4.G.A.3 Identify line-symmetric figures and draw lines of symmetry.

Notes to Educator

You will need this week to prepare for week three, the root analysis. In one of your greenhouses, fill with soil and spread a handful of seeds. Keep watered and in sunlight. You will want a variety of plants in different stages in order to look at their root construction. I used a package of sweet pea seeds in a 16 oz strawberry container. It is a lot, however, will give you a variety of sprouts (some seeds just sprouting, to actual sprouts with great roots).

Differentiation

You should make a journal as well, this will help with any students who may miss a session, need additional time, or if you would like this for the following years.

Students can pair up with complimentary partners.

Remediation

Extension/Enrichment

Students can find the average growth with this chart, or finding the median and mode of the plants/sprouts.

Have students document findings using fractions and/or decimals

Students can document growth using additional graphs/charts.

Have students notice the animals and insects around.

What plants are beneficial to be around each other?

Get a microscope and look at the cell of a leaf from fall, winter, spring and summer. Ask students to identify the similarities and differences.
