Notes for Teachers
This lesson ties in with a field trip to a local wildlife area (could be as simple as a nature trail or a nature preserve.) For those local to the Parker / Lake Havasu area, I am using Bill Williams National Wildlife Refuge. You can modify this to work in your area. This also ties in with any picture books you choose that discuss animal camouflage. The one on the title page of this slide deck is just an example.
List of Materials
Standards
Math
2.MD.D.10
Draw a picture graph and a bar graph (with single-unit scale) to represent a data set with up to four categories. Solve simple put-together, take-apart, and compare problems using information presented in the graph.
Science
Develop and use models to explain that plants and animals (including humans) have internal and external structures that serve various functions that aid in growth, survival, behavior, and reproduction.
Technology
K-2.3.a. Students, with guidance, use provided digital tools and resources to find information on topics of interest.
ELA
2.RI.1
Ask and answer such questions as who, what, where, when, why, and how to demonstrate understanding of key details in a text.
2.RI.6
Identify the main purpose of a text, including what the author wants to answer, explain, or describe.
2.W.7
Participate in shared research and writing projects (e.g., read a number of books on a single topic to produce a report; record science observations).
2.W.8
Recall information from experiences or gather information from provided sources to answer a question.
Objectives:
Today we will learn about plants and animals that are native to our area.
We will use what we know to analyze and investigate how and why animals use camouflage in nature.
We will then create our own unique animal designed to camouflage best in our environment.
Agenda
30-45 minutes - Learn about how animals camouflage and share information
30-45 minutes - Analyze / Investigate how and why animals camouflage by playing a fun game and making a graph of what you learned.
30 minutes - Create. Use what you know about camouflage to create an animal or insect that will blend in to your environment best. It needs to be 1- 3 inches tall and wide. You will take your creature to a natural habitat and take a picture to see how well it can camouflage.
1-2 hours - Field trip. Take your animal to the natural habitat and take a picture for the slide show. While you are there, see if you can find any real life hidden creatures.
Intro/Driving Question/Opening
How and why do animals camouflage in their environment?
Do certain camouflage techniques work better than others?
Hands-on Activity Instructions
Assessment
ELA - ask and answer comprehension questions based on the information provided.
Math - bar graph. Is the information represented accurate? Are there labels and is the graph easy to read? Students should ask and answer at least 3 questions based on the graph.
STEM -Students will self evaluate based on photograph slide show how well their “camo critter” was camouflaged into their environment.
Differentiation
Students can work in pairs with a peer buddy to help out if they are struggling. I would also offer read aloud books for students if the text is too difficult. More time can be added if a student is struggling to get their project done on time.
Remediation
Extension/Enrichment
Use an application such as Tinkercad to create a 3D version of your camo critter
Create a brochure to explain how your animal camouflages in its environment. Can include natural predators and prey that would be found in your location.
