Students predict and test different items to see if they sink or float. In this sink and float lesson plan, students predict whether an item is buoyant or not, and learn that size and weight do not matter when it comes to buoyancy.

Want to get your students motivated in science class? Given only a piece of aluminum foil, assign groups the task of designing a "barge" that will support the weight of a bunch of pennies.  The group who is able to put the most...

Middle schoolers engage in this, the third in a three-part series on ships. The overall lesson series is designed to allow students to extend their understanding of floating, sinking, density, and buoyancy and apply it to the design and...

Students explore water properties by conducting a class experiment. In this buoyancy lesson, students make predictions as to whether or not specific objects will sink or float in water. Students conduct the experiment and record their...

This open-ended boat building exercise is meant to be part of a three-lesson plan series on ships. Links to the other two lessons are included. This particular part is mostly a group lab activity in which they build a boat, find its load...

Students discover fluid dynamics related to buoyancy through experimentation and optional photography. Using one set of fluids, they make light fluids rise through denser fluids. Using another set, they make dense fluids sink through a...

Students use the Scientific Method steps to complete an experiment on various brands of soap to determine their floating capabilities. In this scientific method lesson, students write a hypothesis about the ability of various soap bars...

Students analyze density. In this density lesson, students experiment with floating an egg. Students discover that salt added to water changes the density of the water allowing an egg to float.

Students identify the various states of water and its natural flow downward. As a class, students take digital pictures of different forms of water and create a multimedia presentation describing their photographs. Groups of students...

Students explore letter Ww. In this letter recognition lesson, students participate in country, state, food, literature, physical education, colors, careers, music, and game activities that are linked to the main lesson page. Students...

Students investigate how plants grow by analyzing pumpkins. In this agricultural lesson, students read The Biggest Pumpkin Ever by Steven Kroll, and draw pictures of a pumpkin in each of its growing stages. Students measure and dissect...

Students complete several cross-curricular activities to learn the letter Ff. For this letter recognition lesson, students complete activities that include geography, music, physical education, science, seasonal, space science, and...

Students complete a variety of activities using pumpkins. They visit various stations with various pumpkin activities.

First graders write about vehicles that float.

What is the best way to test water quality? Using plastic bottles, scholars create monitoring sensors to test water quality. Creating three different sensors allows individuals to measure water quality at different water levels.
