Attack of the Raging River
Students explore mass and volume. In this mass and volume lesson, students pretend to be on a hike and have lost their way. Students must cross a river get back on track. Students must use mass, volume, surface area, density, property...

Discovering Density
If you have a set of six various metal rods, you can use this lab activity to challenge science students to calculate their densities. They will use a triple beam balance to measure the mass and the micrometer and ruler determine the...
Curated OER
Temperature and the Density of Air
Here is a hands-on activity in which junior scientists put air into a balloon to create a closed system. They measure its circumference, warm it in hot water, and then remeasure its circumference to discover how temperature affects the...

Chemistry Day With Glitter Wands
First graders observe examples of the three states of matter and identify matter in each of the three states. They make glitter wands to remind them of the three states of matter: solid, liquid and gas. Pupils brainstorm and record...

#17 Determining the Accuracy of Selected Laboratory Glassware
Students calculate the volume of a specific mass of water placed in selected pieces of common laboratory glassware, using the density formula. They then determine the accuracy of the volumetric measurement for selected pieces of...

# 15 A Search for Automated Plastics Recycling Separation
High schoolers are challenged to investigate the physical and chemical properties of plastics and use them to design a system that could be used to separate them. 1st year chemistry students use density for separation, high schoolers...

Why Do Some Things Float?
Students recognize that density determines whether objects sink or float. In this sink or float lesson, students experiment with plastic in three liquids. students drop their objects into the liquids and observe and record their results.
Curated OER
Sea Water Mixing and Sinking
Students investigate the role of temperature and salinity in determining seawater density. They use a Temperature-Salinity Diagram to examine the effects of mixing on density.

Insoluble Paintings
Use this art activity to study insolubility and density. Combining water-based paint and mineral oil will cause a fun and interactive painting. This is a great art project to incorporate during a science unit.
Curated OER
Categorizing Matter
Six envelopes with different substances in each prompt students to group, categorize and identify. They are given the properties of each substance including the density and students sort the six substances into at least three different...
Curated OER
Will It Sink Or Float?
Learners develop their understanding of buoyancy and density related to sinking and floating. They investigate which objects sink and float through experimentation. They determine that different substances sink or float depending on...
Curated OER
Physical Science- Sink or Float?
Learners investigate which objects sink and which ones float. Learners engage in an experiment, make predictions, and record results on a graphic organizer. This is a comprehensive and easy to follow resource.
Curated OER
Sink or Float
Using a variety of objects, learners conduct buoyancy experiments. They make predictions on which object will sink or float and test their predictions. They use a graphic organizer to record their findings.

Sound
Since light travels faster than sound, some people may appear bright until you hear them speak. The presentation covers what sound is, how fast it travels in various mediums, properties of sound, hearing, and the parts of the human ear.

Density and Pressure of a Hot Air Balloon
Using a dry cleaner bag and a blow dryer, create a hot air balloon! The materials list suggests obtaining one dry cleaner bag per student, but since this is probably inconvenient, consider doing this as a demonstration during a lesson on...

Introduction to Density
Seventh grade scientists weigh in on the concept of density. In a nutshell, they participate in the following activities:
Measurement of the mass and volume of fruit in order to compare densities
Measurement of the mass of oil and water...

Float a Hot Air Balloon
This activity will lift spirits in your class, but there is little scientific explanation for what makes a hot air balloon rise. As you are teaching middle school scientists about density and convection, you can incorporate this...
Curated OER
An Intuitive Introduction to Density
Students complete experiments discovering the relationship between density and mass. They use the internet to gather information before the experiment. They discuss the activity once it is completed.
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...
