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
Young scholars 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
Students 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, students gathered...

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...

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 lesson plan 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.

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...

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...

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...

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...

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...

Volume and Density Worksheet
All 20 of the problems on the worksheet involve the computation of cubic volume or density. As long as your young scientists can apply the appropriate mathematical formulas, they will succeed in solving these problems. They are not...

Density of a Paper Clip Lab Review
Even though this assignment is brought to you by Physics Lab Online, it is best used as a math practice. Middle schoolers calculate the range, mean, mode, and median for a list of eight different paper clip densities. They analyze...

Buoyant Behavior
Combine science and literature with this lesson on buoyancy. Read There's an Ant in Anthony by Bernard Most to examine words containing the letters a, n, and t. Then introduce your class to the word "buoyant." Demonstrate how an egg...

Stacking Water
Students experiment with different salinities of water using straws and different colors of water. They collect and interpret data from the experiment.

Iceberg Ahead: How Does Temperature Affect the Density of Water?
Demonstrate how ice floats on water and get the class thinking about why icebergs are so deceiving. Investigators then experiment with mixing water of the same temperature and water of different temperatures. Make sure to explain the...

Galileo's Thermometer: Measuring the Density of Various Unknown Liquids
Sprouting scientists explore the concept of density by making mass and volume measurements for five different liquids. From these measurements, they calculate densities. They apply their learning to explain Galileo's thermometer works...
