Ricochet Science: Biology 101 - The Chemical Basis of Life
Introduce young biologists to basic chemistry concepts with a series of eight informative videos covering the structure of an atom, properties of water, acids, bases and pH, electronegativity, polar bonds, and hydrogen bonds, isotopes,...
Lesson Planet: Curated OER
Inquiry in Action: 5th Grade Science Lessons
Looking for remote learning science lessons aligned to NGSS? Check out the resources in this inquiry-in-action packet. Designed for fifth graders, the 16 lessons are divided into four chapters: Matter is Mad of Tiny Particles, Substances...
Lesson Planet: Curated OER
Middle School Chemistry: Chapter 3 - Density
Chapter three in the middle school chemistry unit explores the relationship between volume and density. Young chemists conduct experiments to find volume through displacement, observe how temperature affects water density, and how the...
Lesson Planet: Curated OER
The Physics of Fluid Mechanics
In this collection, Pascal’s law, Archimedes’ Principle, and Bernoulli’s Principle aid young engineers in understanding the physics of fluid mechanics. Armed with the knowledge of how forces are applied to fluids, scholars design...
Lesson Planet: Curated OER
Environmental Engineering and Water Chemistry
Introduce young scientists to the fundamentals of environmental engineering with a nine-resource collection that looks at air, land, and water quality concerns. The unit begins with a PowerPoint presentation that provides background...
Lesson Planet: Curated OER
Ocean and Great Lakes Literacy: Principle 1
Is your current lesson plan for salt and freshwater literacy leaving you high and dry? If so, dive into part one of a seven-part series that explores the physical features of Earth's salt and freshwater sources. Junior hydrologists...
Lesson Planet: Curated OER
Buoyancy
Swimmers know to float by turning their bodies horizontally rather than vertically, but why does that make a difference? In an interesting lesson, scholars explore buoyancy and the properties of air and water. They test cups to see which...
Lesson Planet: Curated OER
Temperature Affects Density
Different substances can have different densities, but can the same substance have different densities? Lesson explores the effect of temperature on the density of water. Extension idea connects the concept of how melting ice in lakes...
Lesson Planet: Curated OER
Density: Sink and Float for Liquids
We don't think of liquids as floating typically, but a quick look at any oil spill tells a different story. Lesson explores various densities of liquids and why this fact is important. After observing the density variation, scholars...
Lesson Planet: Curated OER
Density of Water
We know solids have a density we can measure, but what about liquids? Lesson explores this concept and allows scholars to explore the relationship between volume and density. Graphing and analysis questions round out the activity.
Lesson Planet: Curated OER
MEASURING THE DENSITY OF WATER
Students perform an experiment to measure the density of tap water vs. salt water.
Lesson Planet: Curated OER
Heat Up and Cool Down
Don't be so dense! Using food coloring, pupils conduct two experiments with the difference in densities of hot and cold water. In the first experiment, learners add dyed hot and cold water into room temperature water and observe how the...
Lesson Planet: Curated OER
The Density of Liquids
It's in your destiny to study density! Young scientists conduct an experiment to study the relationship between weight and density. They compare weights of liquid samples of different substances and predict how their densities are related.
Lesson Planet: Curated OER
Design a Submarine
Don't just sink the boat. Using a closed container as a submarine, pupils experiment to see what to add to the container to make it float, sink to the bottom, and hover in the middle. After finding one option, learners see if they can...
Lesson Planet: Curated OER
Temperature, Salinity and Water Density
The difference between sinking and floating may be a little salt. Young experimenters analyze the effect of salt and temperature on the density of water. They use their results to predict the effect of climate change on ocean ecosystems.

Rainbow Water Stacking – Density and Salinity
Create layers of water. Pupils investigate different densities of colored water caused by salinity by trying to stack layers of water. Scholars compare two water samples to determine which is the most dense. As the class members work...
Lesson Planet: Curated OER
Motion in the Ocean
How do temperature changes affect ocean currents? Scholars explore convection currents by demonstrating the flow of water in a baking dish. They use ice, heat, and food coloring to see currents. Then, they draw conclusions about their...
Lesson Planet: Curated OER
Global Ocean Currents
What forces drive the ocean's currents? Science scholars observe global ocean currents at different depths to explore their characteristics and patterns. Part of PBS's Weather and Climate series, the resource includes teaching...
Lesson Planet: Curated OER
Density
Do you know how to change the density of water? Show your class using a video that explains what density is and how to calculate it. Then, it goes into the units we use to measure density and how temperature impacts it. Finally, it...
