Paper Clip Sailing
Young scholars explore water, molecules, and surface tension. In this floatation lesson, students discover why some objects are able to float on water as they follow the procedures included in this activity.

Exploring the Properties of Matter in the Preschool
Students study the properties of the physical and natural world. In this properties of the physical and natural world lesson, preschool students work at discovery tables to see how simple machines work, what happens when items are put...

Water Exploration Station
Students explore the characteristics of water. In this water exploration lesson, students participate in various learning centers to inquire how water drains and how to increase the flow of water. Students use estimation and measurement...

Buoyancy Boats
What did the sea say to the boat? Nothing, it just waved. An inquiry-based lesson starts with a simple concept on the Archimedes Principle and challenges pupils to make something out of clay that floats. Then, they design an object out...

MEASURING THE DENSITY OF WATER
Students perform an experiment to measure the density of tap water vs. salt water.
Curated OER
Immiscible Liquids and Density
Students will make a lava lamp. In this density lesson, students will combine water and oil and make observations, then add salt to the oil and observe the oil sink, then float again when the salt dissolves in the water.

Grand Designs And Great Failures
Students extend their understanding of floating, sinking, density, and buoyancy and apply it to the design and testing of ships. students discover that most ships are constructed very similarly-whether they are schooners or destroyers.

Ships 3: Grand Designs And Great Failures
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...

Investigating the Effect of Salinity on the Density and Stability of Water
Water with varying amounts of dissolved salt are dyed and then used to compare densities. The objective is to discover the effect of salinity, and therefore density, on ocean water on the stability of the ocean. Many branches of science...

Rock My World
Students conduct a hands-on experiment designed to demonstrate how continents and oceans formed and why the manner of formation is relevant to a study of volcanoes.
Curated OER
Stacking Water
Students experiment with different salinities of water using straws and different colors of water. They collect and interpret data from the experiment.

Teacher's Guide For: Water Temperature and Salinity Experiment
Learners experiment with water density, temperature and salinity. For this water lesson, students observe how the coldest water sinks to the bottom of a test tube, and how saltwater sinks in comparison to freshwater.

Float My Boat
Fourth graders, in groups, experiment with density and the displacement of water by creating and designing their own boats and seeing which boat holds the most centimeter cubes without sinking..
Curated OER
What Floats Your Boat?
Young scholars discover the Archimedes principle through a buoyancy experiment. They measure the water displacement of a lump a clay which is denser than water then reshape the clay into a bowl which floats but displaces more water.

The Floating Golf Ball
Fourth graders discuss density. For this floating golf ball lesson students complete a lab activity on density while working in groups.

Give Me a Tall Ship
Sixth graders develop an understanding of floating, sinking, density, and buoyancy and apply it to the design of testing of ships.

Solve a Problem: Build a Boat
Students build a boat that float and hold as many pennies as possible, then discuss the process of building the boat and relate the experience to experiences they encounter in life.

Marine Debris
Now is the time to educate tomorrow's citizens to care for the planet, and here is a lesson to help facilitate the process. Collect some marine debris and bring it into class. Have your class separate it into types and then test each...
Curated OER
Marine Debris
Pupils perform experiments to examine if debris float, or blow in the wind. The effects of these characteristics on the marine debris are then discussed. They determine how a material can influence what becomes marine debris.

Note Taking And Skills And Lab Reports
Students perform simple and fun experiments to use the scientific method, take careful notes, and write a lab report. They first make and test a hypothesis about how many drops of water they can fit on the face of a penny and then test...
Curated OER
Float Your Boat
Students investigate buoyancy, displacement and density. In this flotation lesson students study the Archimedes' Principle, analyze data and draw conclusions.
Curated OER
Wonderful Water
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...

How Wet Can You Get?
Students visit a swimming pool and brainstorm different water sports and what benefits swimming has over other types of exercise. They then discuss buoyancy and water pressure and when how objects sink or float before playing a game of...

Investigating Density: Heavy Ice
Students end up learning the formula for density and calculate the densities of various materials, and predict if they sink or float.
