Background for Educators
ABCDE

Most of us, adults and children, associate sketching with making a pretty picture. This association can limit us, especially if we feel we are not good at drawing. A scientist sketches to record and communicate information, not to make art. Along with a drawing, a scientific sketch often includes labels and diagrams, questions and explanations. You don’t have to be an artist to create a successful scientific sketch. You simply have to take time, observe closely, and record what you see.

Recording what you see is different from drawing the picture you have in your head. Many of us have cartoon-like images in our head of trees, flowers, houses, apples, rabbits, etc. When you set out to sketch a real thing, it’s important to focus on the individual specimen in front of you, rather than the generalized image you carry in your head. You can help students understand this by focusing on particularities of an example object – like a leaf with holes in it, or an irregular rock. These particularities are often very important for scientists to record.

One way to help students feel successful is to give them a few practical suggestions for how to sketch a given object. At the very least, give them a first step (this will vary depending upon the object), so that they know how to get started. [See the for an example of a step-by-step process for drawing a redwood leaf.] If you provide enough scaffolding, even those students who feel they are “bad at drawing” will have an entry point. It’s very likely those students will come away surprised at their own abilities.

The pneumonic ABCDE [i] gives students a clear idea of what makes a good scientific sketch. It also enables you, as a teacher, to give meaningful feedback to students. Rather than praising a drawing as “pretty,” you can say, “Great job making your sketch big; it really helps me see the details,” or “I’m glad you included explanations in your sketch; they will help another scientist understand what’s important.” For constructive feedback, try: “What could you do to make this sketch more accurate?” or “I bet adding color would help another scientist understand what the object really looks like.” This kind of feedback is concrete enough for students to understand why they’ve done a good job, and what steps they can take to improve their work.

Teacher Prep (15 minutes)
leaf sketch
  • Gather sketching materials.
  • Gather leaves or other simple, natural objects for students to sketch. For activity to work, all students must have the same type of item, but many items could work. They should be simple to draw and have variation from one item to the next. Consider using: leaves, shells, rocks, fruit, seeds, or flowers.
  • Set up or print .
Introduction (15 minutes)
Leaf sketch

1. Have students retrieve their notebooks, open up to a new page, title it “Scientific sketch” and add this page to the table of contents.

2. [] Introduce students to the purpose of a scientific sketch. If possible, do Science Notebooks Across Time as a prep lesson before this one, so that students have already discovered why scientists sketch. If you haven’t done that lesson, you can explain that scientists use sketches to capture information for themselves, and communicate information to others. They often sketch when they are doing field research, observing a plant or animal they cannot take back to the lab. Sketches are sometimes more valuable than photographs because they can include specific data the scientist wants to highlight, as well as the scientists’ observations and questions.

3. [] Put nervous students at ease by emphasizing that a scientific sketch is not about making a pretty picture. It’s about communicating information.

  • Explain the difference between “drawing what you see” and “drawing the idea in your head.” (See more on this distinction in the above Background for Educators)

4. bet36体育在线真的吗[] Introduce the criteria for a successful scientific sketch. Explain the meaning behind each word in the pneumonic: ABCDE

  • An accurate sketch describes the true nature of an object – size, shape, texture, etc.
  • The sketch should be big so that we can see details, rather than squished in one corner of the page, and hard to make out
  • When possible, communicate more information by making your sketch colorful
  • Use words and drawing to make your sketch as detailed as possible. All the little details are what make the specimen you are studying distinguishable from others like it.
  • Add labels, questions, and conjectures about what you see. These words make your sketch explained.
Sketch a Leaf Instructions (10 minutes)

5.bet36体育在线真的吗 [] Explain that students will be practicing scientific sketches with leaves (or whatever object you have chosen). Their task is to make a sketch that is specific enough that another student will be able to pick their leaf from a pile, based on the sketch alone. Depending on the age of your students, you may want to front-load all the directions, or give them a few steps at a time. [ii]

  • [] Start by placing your leaf on the page. Rather than tracing the shape of the leaf, place little dots at the ends of each needle, to get a general outline of the leaf’s shape. Then remove the leaf from the page
  • [] Next, draw the centerline and connect it to the dots you drew. You don’t have to complete all the needles to get a sense of the shape.
  • [] When you’re ready to add more details, choose an area where something unusual is happening on your leaf. Blow it up in a zoom bubble.
  • [] Remember to include words in your sketch. Labels can indicate size, color, texture, etc.
  • [] You should also include your scientific questions about this leaf. Those questions can start with the words, “I wonder..."
  • [] Add color to show what your leaf really looks like.

Students Sketch (25 minutes)

6. [] bet36体育在线真的吗Give students ample time to sketch their leaves, 15-30 minutes.

  • Give occasional reminders to include labels, questions, and colors in their sketch.
  • If students claim to be finished quickly, prompt them to deepen their sketch by attending to one of the ABCDE criteria. Remind them that another student will need to be able to identify their leaf, based on the sketch alone.
  • Periodically give them a sense of how much time they have left, or add time if it seems like they need it.
Leaf Matching Game (10 minutes)

7. Explain that students will break into smaller groups of about 10 people, to play a Leaf Matching game. If you’d rather do this activity as a whole class, that will work too. It will just take longer. Each group needs to stand in a circle. Once you have arranged the group into small circles or one big circle, give the following instructions [ii] :

  • Place your leaves in the middle (on table or ground).
  • Place your notebooks, with your sketches showing, in a ring around the leaves. Don’t put your notebook right next to your leaf
  • Take turns making a match by picking up a leaf and placing it on top of the sketch you think it matches. The scientist who made that sketch can tell you whether you are right or wrong.
  • Once all sketches are matched with leaves, discuss: what helped you make a match? What do you notice about the different sketches?

Wrap Up (10 minutes)
Wrap up

8. bet36体育在线真的吗Ask students to share out what they noticed about the different sketches.

  • How did different scientists in our group choose to record information about their leaves?
  • What helped you make a match? What details were important for identifying each leaf?
  • How is sketching as a scientist different from or similar to sketching as an artist?
