Nibble, Sip, and Grind

ipm45Download This Lesson: Nibble, Sip, and Grind

Brief Description: Students will learn about different insect mouth parts and how that impacts their diet. They will observe, compare and contrast the three types of mouth parts using new vocabulary from the lesson. Students will also make hypotheses and experiment using variations of the three feeding types.

 

Focus Areas: Animal Lifestyles; Science, Math

Focus Skills: comparing and contrasting, observing, forming a  hypothesis, drawing conclusions

 Objective

To understand that the variety in insect mouthparts are adaptations to their diet

Essential Questions

  • What do insects eat?
  • How do insects eat?

 Essential Understanding

 Insects’ mouths are adapted to eat food within their environment.

 Background

 Insects have a variety of ways to obtain nourishment.  Mosquitoes, adult fleas, lice, and some flies puncture tissue with a slender beak, a PROBOSCIS, and suck the fluids within.  Butterflies, moths, and bees also dine on fluids, but their PROBOSCIS lacks the piercing adaptation and is extended only when their feet touch and “taste “a sweet solution.  A spongy tip, LABELLUM, on the tip of the PROBOSCIS allows most flies to sop up liquids or easily soluble food.  Other insects like ants, grasshoppers, beetles, and caterpillars nibble and grind their food with jaws, MANDIBLES, which move horizontally.

Vocabulary         

labellum – the spongy tip of some insects’ proboscis
mandibles – the chewing mouth parts of some insects
proboscis – the slender feeding tube of some insects

Logistics    

Time: 30 minutes,    Group Size: 5 to 30,   Space: an area large enough for children to move  about comfortably

Maine Learning Results

PreK-2

MA – B. Data

 **B2. Students read, construct, and interpret picture graphs.

(**Extension: Students construct a picture graphs and a bar graph based on tallies.)

SCI – A.  Systems

   A1.  Students recognize that parts work together, and make

          up whole man-made and natural objects.

            a. Explain that most man-made and natural objects are

               made of parts.

            b. Explain that when put together, parts can do things

               they could not do separately.

   A2.  Students identify models and the objects they

           represent to learn about their features.

            b. Use a model as a tool to describe the motion of

                objects or the features of plants and animals.

Grades 3-5

MA – B. Data

 **B2. (Grade 3) Students read, construct, and interpret bar

           graphs.

           (Grade 4) Students collect and represent data in

            tables, line plots, and bar graphs, and read and

            interpret these types of data.

           (Grade 5)  Students read, construct and interpret line

            graphs.

 

 (**Extension: Students in grades 3 & 4 construct bar graphs, In Grade 5, students construct line graphs of tally results.)

 

SCI – A.  Systems

   A1.  Students explain interactions between parts that make

          up whole man-made and natural things.

            a. Give examples that show how individual parts of

               organisms, ecosystems, or man-made structures

               can influence one another.

            b. Explain ways that things including organisms, eco-

               systems, or man-made structures may not work as          

               well (or at all) if a part is missing, broken, worn out,

                mismatched, or misconnected.

   A2.  Students use models to represent objects, processes,

           and events from the physical setting, the living 

           environment, and the technological world.
