Buoyancy in Water
Change where an object floats in water. Pupils experiment with a Cartesian diver by squeezing on the side of a plastic bottle. Learners pay attention to the bulb of the pipette as the bottle is squeezed to determine what is happening...

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...

Scuba Training
How does a scuba diver control whether they sink or float? Scholars observe the relationship between absolute pressure and depth below the surface in an undersea simulation. They control the diver size and depth to center of mass to...

Exploring Density with Salt and Fresh Water: Part 5
This particular lesson was written by the National Earth Science Teachers Association, but density is a concept that you can teach at the beginning of the school year in your life, physical, or earth science classes. It would be fun to...

Float and Sink
In this float or sink worksheet, 8th graders solve 1 science/math puzzle about displacement of water; the answer is available online.
Curated OER
Buoyancy
This is a brief survey of the states and properties of matter directed toward upper elementary physical scientists. Solids and liquids are compared. Density and buoyancy are related. Use this presentation just prior to demonstrating...

Condiment Diver: The World's Simplest Cartesian Diver
Students examine buoyancy. In this density lesson students form a hypothesis, collect data and draw a conclusion using the data.

Density - To Float or Not to Float? That is the Question!
Students investigate how to find the density of fluids and solids using math. Students also learn how to find the density of regular and irregular shaped objects.

Can You Make A Penny Float?
Students explore the concept of density by trying to make a penny and other materials float.

Density Studies of the Earth
Density comes to life as investigators place soda cans into containers of various liquids to find if they sink or float. They layer different density liquids, compare densities of different gases, and more. A total of six different...

Science - "Why does it float?" - Exploring the Concept of Density
In this density worksheet, students read about density, volume and mass. They then use what they learned to answer the 8 questions on the page. The answers are on the last page.

Density
Second graders watch a demonstration and complete an experiment to determine how an objects' density allows it to float or sink. They work in small groups to assimilate the characteristics of items that float as opposed to simply...

What Floats Your Boat?
This open-ended boat building exercise is meant to be part of a three-lesson 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 line...

"Mr. Betts and Mr. Potts"
First graders listen to the book "Mr. Betts and Mr. Potts" and examine the career of being a veterinarian. They categorize animals based on whether they could be house pets or not, develop a class pet graph, and list the various...

Activity # 13 Float or Sink?
Students have seen that solids, which are more dense than a liquid, that sinks in that liquid and solids, which are less dense than a liquid, that floats on that liquid. They use a metal boat to float in water. Pupils comprehend that...
Curated OER
Floating and Sinking
Students conduct experiments in which they investigate which materials float and which sink. They examine what qualities the materials that float have in common. They carry out a scientific investigation, predict, and test their...
Curated OER
Density: Floating, Sinking, and Suspending
Students observe teacher demonstrations that illustrate density. For this density lesson, the teacher demonstrates how air bubbles in a carbonated drink can cause a raisin to float and how an egg sinks in fresh water, but floats in salt...
Curated OER
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...

The Floating Golf Ball
Students explore density by floating golf balls. They explore having their golf balls float halfway in a container of water and discuss density and its realtionship to where the golf balls are floating. After adding food coloring, they...

To Float or Not to Float - A Lesson on Density
Students observe and experiment with the concept of density. This is done using a simple experiment that helps them to apply scientific principles of observation and proving a hypothesis.

Prime and Composite Numbers - Kenwood Academy
Learners investigate prime and composite numbers. They use a number chart and cross out multiples of 2,3,5 etc. up to 100. Pupils fold pieces of masking tape around pennies and label them with composite numbers, then fold masking tape...

Defining Density
Three simple activities kick off a unit investigation of density. Your physical scientists make observations on the volume and mass of wood, water, and rocks, and make comparisons. Though this is written for grades three through eight,...
