Curated OER
Elements, Compounds, and Mixtures
In this elements, compounds, and mixtures worksheet, students answer questions about the properties of elements, mixtures, and compounds. Students identify the physical changes that is made to a substance to determine if it is an element.

Design a Plankton
Young scholars explore animal and plant adaptation. In this ecosystems science lesson, students view websites to gain information about plankton and its interdependence within ecosystems. Young scholars identify ways in which...
Curated OER
It Matters
Young scholars use descriptive vocabulary to discuss the attributes of matter. Then, they sort objects or pictures by the type of matter they are comprised of. Finally, students match objects of matter with similar attributes and...
Curated OER
Wonderful Water
Students identify the various states of water and its natural flow downward. As a class, students take digital pictures of different forms of water and create a multimedia presentation describing their photographs. Groups of students...

Descartes' Diver
Pique interest in water pressure, demonstrate buoyancy, and explore water displacement concepts with a homemade Cartesian diver. You may want to change the name of the toy, however, as is is not documented the Rene Descartes...
Curated OER
Mystery Liquids: Linear Function
High schoolers determine the linear equations of the density of water and oil by collecting data on the mass of various volumes of each liquid. They construct scatter plots from the data and use these to write the linear equations for...
Curated OER
Density Lab Activities
Students participate in several density lab activities in order to clarify the misconceptions that solids sink and liquids float. Students work with triple beam balances to find mass of objects to calculate density.
Curated OER
Making Predictions
First graders write with his or her pencil on a worksheet created by the teacher his or her prediction of whether each part of a pumpkin will sink or float. They drop each of five objects in the water one at a time allowing enough time...
Curated OER
Interactive Writing
First graders write about vehicles that float using the interactive writing procedure.
Curated OER
The Weight of Water
Pupils examine how salt water is more dense than fresh water. They discuss how manatees need to float and sink, conduct a sink or float experiment, and conduct an experiment with eggs and salt and fresh water.
Curated OER
What are Properties of Wood?
Students use hands on scientific observation to determine characteristics of wood. They work directly with the materials and record their observations. Students test if wood absorbs water, if wood floats or sinks, and if all wood...
Curated OER
Regular Coke versus Diet Coke, Which is Denser?
Students investigate the density of liquids. In this geometry lesson, students calculate the volume and differentiate between volume, mass and density. They observe similarity and differences between coke and diet coke.

Buoyancy Bulls-Eye
Why does a seastar sink, but a jellyfish float? Through a fun investigation, learners examine the concept of buoyancy using simple household items. The challenge: create neutral buoyancy for an action figure in water. With ample...
Curated OER
Liquid Rainbow
Learners develop their own techniques for drawing a small sample of solutions into a straw. They hypothesize ways to increase the density of water, and discuss how salt-free rainwater tends to float on top of salty seawater.

Clay Boats
Clay itself sinks, but clay boats float. Why? Young engineers build clay boats to learn about buoyancy. They test the weight the boats can hold using washers and then tweak their designs to make improvements, following the engineering...
Curated OER
Exploring Buoyancy
Students use materials found at a resource table to design simple devices that will house instruments to take water samples from a tub of water. They design 3 instruments, each varying in density so that one will float, one will hover...
Curated OER
WS 1.7 Density /Archimedes Principle
Archimedes' principle is practiced as chemistry learners practice computing the density of different gases, liquids, and solids. Using a chart of standard densities, they also identify unknown materials by similar calculations. Fifteen...
Curated OER
Wipe Out
Learners examine the flow of water. They observe and test the properties of water by using sticks in flowing water. The lesson has streaming video, resource links to access, and a good hands-on activity that is clearly described in the...
Curated OER
WS 1.7 Density
In this density worksheet, learners calculate the density of objects given their mass and volume. They are given a table with the density of a variety of substances and given the mass or volume and must find the unknown.

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...
Curated OER
States of Matter
Properties in measurement, pressure and viscosity of solids, liquids, and gases are the main topics covered in this slideshow. The explanations of Pascal's, Bernoulli's, and the Venturi effects are very clear. Easy to understand diagrams...
Curated OER
Animal Homes
Match animals to their environments with a cute lab activity. Kids draw a line between each animal, such as a fish, a rabbit, and an ant, to the place where it lives. For hands-on practice, a science investigation instructs learners to...
Curated OER
It's A Gas!
Fifth graders complete a worksheet which has them place a list of gases in order from the least to the most dense. The density in grams is given for each. There's a good paragraph which provides background knowledge about the volatility...
