A WebQuest for 1st or 2nd Grade (Teeth/Dinosaurs)
This WebQuest is designed for children to observe the shape of humans’ and animals’ (including dinosaurs!) teeth in order to conclude whether they are/were herbivores, carnivores, or omnivores.
This WebQuest is geared toward first or second graders. It focuses on science, specifically shapes of teeth. It also involves English because the children learn new words such as “herbivore” and “incisor.”
Prior to completing this lesson, students should have a general understanding of computers: how to scroll down the page, click on links, and use the back button.
As a result of this WebQuest, students will learn how to decipher whether an animal is a herbivore, carnivore, or omnivore based on the shape of their teeth. They will use critical thinking skills, as well as creative problem solving, and observation skills. Students will also develop a better sense of teamwork while working in groups to solve the presented problem.
Standards met by the Ohio Department of Education:
Life Sciences Standard:
B. Explain how organisms function and interact with their physical environments.
· Explore that humans and other animals have body parts that help to seek, find and take in food when they are hungry (e.g. sharp teeth, flat teeth, good nose and sharp vision.) (3)
C. Describe similarities and differences that exist among individuals of the same kind of plants and animals.
Scientific Inquiry Standard:
A. Ask a testable question.
· Ask “how can I/we” questions. (1)
· Ask “how do you know” questions (not “why” questions) in appropriate situations and attempt to give reasonable answers when others ask questions. (2)
C. Gather and communicate information from careful observations and simple investigation though a variety of methods.
· Grade 1: 4, 5, 8, & 9
· Grade 2: 5 & 10
There are also English language arts, vocabulary, reading, and research standards involved with this WebQuest.
This WebQuest is organized into three parts. Depending on how much computer time, you may want to have your students complete each part in one day, spreading the lesson over three days.
Students will use this WebQuest to read the information provided, and click on links in order to obtain more information from outside sources.
Students will be divided into groups of three, each person completing a different task. The three tasks are data recorder, word wonder, and drawing ace. The data recorder is responsible for writing down the group’s ideas. The word wonder is given specific words to find on the web pages and define. The drawing ace is responsible for drawing pictures related to answering the questions provided. I would suggest to put students in groups with others they would get along with as they will need to work as a team, but not necessarily letting them choose their own groups.
Children should be watched to make sure they’re working cooperatively, but the lesson is self-contained and self-explanatory. The only other things the students will need is plenty of paper to write and draw on and drawing/coloring instruments.
Each group of three students needs their own computer. They also need a mirror to use to look at their teeth.
Incorporating this WebQuest into a lesson about animals and what they eat would be recommended.
The web sites the children will be visiting are:
http://www.healthyteeth.org/toothGrowth/toothGrowth.html - explains the where different types of teeth are in the human mouth.
http://www.healthyteeth.org/toothGrowth/different.html - explains the functions of the different types of teeth in the human mouth.
http://www.cedarville.edu/academics/education/resource/subjects /science/mammalcb/teeth.htm - shows the different shapes of teeth that herbivores, carnivores, and omnivores have.
http://www.bbc.co.uk/schools/scienceclips/ages/7_8/teeth_eating.shtml - game incorporating herbivores, carnivores, and omnivores.
Depending on how many students/groups you have to watch, one teacher may be enough. If you have a large class and feel overwhelmed with watching so many children, you may want to request the assistance of a teacher aid or another helpful adult.
When students complete this lesson, they will be able to discover whether animals are carnivores, herbivores, or omnivores based on the shapes of their teeth. This is useful in explaining why animals eat the things they do and how they are equipped to do so.
My WebQuest was influenced by Jane Ochoa-Richardson’s WebQuest, “Dinosaur Snacktime.”

Thank you for enjoying my WebQuest!
