Students explore seashells through various activities. In this oceanology lesson, students demonstrate knowledge of seashells and their properties by creating a dot-to-dot picture, reading books about seashells and creating seashell prints by using paint. There is also a seashell song included with this lesson.
Students take a trip to Galveston's beaches. They collect empty shells, and visit the internet site to identify the seashells they find. Students visit the linked websites to view pictures of seashells and aid in their identification. Students are first encouraged to divide their shells into two categories, univalves and bivalves.
Practice descriptive language in this lesson, which prompts elementary and middle schoolers to write detailed descriptive sentences describing a seashell. They write a description of a shell, create an illustration, and other students have to guess which shell they are describing. This lesson is a great way to bring descriptive and sensory language into any writing unit.
Plant and animal life of the ocean is the focus of this science lesson. Young scientists sort a variety of seashells and explore why many sea animals have shells. They examine the shells, write journal entries highlighting the characteristics of the shells, and match up pictures of sea animals with the shells that they use.
In a multiple-disciplinary lesson, little ones read the book, Is This a House For Hermit Crab? They create a classroom habitat for a hermit crab, classify various shells by size, and create sand art. What a memorable and educational addition to your kindergarten or preschool curriculum!
A fossil is worth a thousand words! Individuals craft their own amber fossil of an insect in addition to molds and casts of seashells. A third activity takes the instructional activity a notch higher: Learners measure stride lengths between tracks and traveling speed to calculate dimensionless speed. Then, paper dinosaur tracks are laid out for them to perform the same calculations with. In a final activity, take the class outdoors to make casts of actual animal tracks. Use this instructional activity to enrich your earth history curriculum.
There are three separate lessons within this resource that can be used together, or that can each stand alone. In the first, five simple activities allow junior scientists to examine the amazing properties of water. In the second, they compare the strength of potato chips with ridges and without to demonstrate why seashells might have ridges. The third lesson gets learners thinking about what objects might be unsafe to pick up when beach combing. Geared toward younger scientists, these lessons could be used in an ocean unit or prior to a field trip to the shore.
Four lessons introduce elementary ecologists to salt marsh and sandy beach habitats. In the first lesson, they place shells and other materials in vinegar to determine if they contain calcium carbonate. In the second lesson, they read a mystery in which a blue crab has gone missing. The mystery is solved by the habitat clues that you provide. In the third lesson, learners make plankton models from playdough and experiment to see if different shapes float more readily. The final lesson prepares them for a field trip to the salt marsh.
After learning about different sedimentary rocks, have groups of geologists make models of them. Using sand, gravel, chalk, seashells, and plaster, make a rock model that could have formed in a particular environment. Make sure to have real rock specimens for learners to compare their models to. This lesson is a little more materials-heavy and time-consuming than it is worth.
In this Algebra I activity, 9th graders analyze a problem in which basic assumptions must be made about cost and demand for the product or item. Students use a graph to make predictions and determine the best price at which to sell an item. The four page activity contains six questions. Answers are not included.
