Atomic Theory
An extremely thorough presentation walks new chemists through the basics of matter. There really isn't a unifying theme, however So many topics are covered: forces, elements, atomic structure, chemical properties, compounds, quarks,...
Exploratorium
Bubble Suspension
Create a cushion of carbon dioxide gas to float some soap bubbles on. Many concepts can be demonstrated through this activity:
Carbon dioxide gas is more dense than air
Bubbles are semipermeable, allowing only carbon dioxide to diffuse...

Investigating the Line
Note that this lesson is best paired with the preceding lesson in the unit. In that lesson, elementary physical scientists observed that the color coating of M&Ms® candies do not mix when dissolved off of the chocolate surface. Now...
Curated OER
Denser Sensor
Fourth graders calculate density, compare densities of solids and liquids, measure liquids using a balance, and investigate the significance of density. They conduct an experiment to determine an order of densities, and complete a...
Curated OER
Diving Raisins
Students hypothesize and observe what occurs when raisins are dropped in a carbonated liquid. They examine buoyancy and how density effects ascent and descent.
Curated OER
Day Six: Floater What Ifs
Students observe earth science by examining results from an experiment. In this buoyancy lesson, students practice floating different items in two different liquids and identify why certain objects will float and others sink. Students...
Curated OER
Day Two: Generating New Questions
Students investigate buoyancy by participating in a lab experiment. In this density lesson, students utilize vinegar and alcohol in beakers and attempt to float different items in them. Students analyze which items float and do not while...
Curated OER
Matter
In this matter worksheet, students are given 10 sentences with italicized terms that are wrong. Students correct the terms to appropriately fit the sentences. Topics are related to matter such as physical and chemical properties, solids,...
Curated OER
Motion in Fluids
Students explore physical science by participating in a science activity. In this liquids lesson, students discuss how fluids can be affected by motion unlike solids. Students define other scientific vocabulary terms and conduct a motion...
Curated OER
Why Could the Hindenburg Float?
Tenth graders experiment with floating and sinking objects and heavy and light liquids, using correct terms, like density, to explain what happens. In this Hindenburg activity, 10th graders watch a demonstration called the...
Curated OER
Heavy Ice: Day Five
Students explore physics by conducting a class experiment. In this density lesson, students examine a list of items and discuss whether they will sink or float and then determine their density. Students examine the objects over five days...
Curated OER
Water Unit
For this water worksheet, learners review the properties of water including the density, boiling point, and evaporation. Students define mixture, solute, and solvent. This worksheet has 22 short answer questions.
Curated OER
Haloalkanes: Physical Properties
In this gases learning exercise, students use data tables comparing the density and boiling points for given haloalkanes to complete 3 short answer questions.
Curated OER
Color Splash
Students investigate density. In this density lesson, students conduct an experiment using food coloring. Students observe the differences in mixing food coloring in water and oil.
Curated OER
State of Matter - Atoms
Learners examine and discuss how atoms change from solid to liquid to gas. They inflate a balloon by melting ice that converts to steam, and discuss the results.
Curated OER
Brain POP - Properties of Matter
In this properties of matter learning exercise, students complete 18 fill in the blank questions about mass, density, volume or weight.
Curated OER
Brain POP- Properties of Matter
For this properties of matter worksheet, students answer 18 questions about mass, density, volume or weight. All of the questions are multiple choice.
Curated OER
Water and Ice
Students investigate the states of matter. In this physics lesson plan, students use water and ice to demonstrate the characteristics of a solid and liquid. Students record their observations as the state of the water changes.
Curated OER
Water and Ice
Students observe what happens to water as it goes from a solid to a liquid. In this exploratory lesson plan students gain an understanding for the water cycle while working in groups observing what happens to water as it changes...
Curated OER
Stacking Water
Young scholars experiment with different salinities of water using straws and different colors of water. They collect and interpret data from the experiment.
Curated OER
Sink It
Introduce your class to the concept of sinking and floating. In groups, they classify objects after making predictions about which materials will sink or float. They record their results and create graphs and charts to share with the class.
Curated OER
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...
Curated OER
Seashore Explorers
There are three separate lessons within this resource that can be used together, or that can each stand alone. In the first, five simple activities allow junior scientists to examine the amazing properties of water. In the second, they...
Curated OER
Describing the Physical World
In this physical world worksheet, students review concepts relating to the chemical and physical properties of matter, density of matter, and if matter is a solid, liquid, or gas. This worksheet has 9 terms in a word puzzle, 4 true or...
