For this preparation of triiodomethane learning exercise, students use propanone to prepare triiodomethane. Students use filtration and recrystallization to produce the product. They determine the melting point using a melting point...

Pupils explore linear functions in this lesson when they collect and analyze data as a chemical reaction proceeds. Learners record pressure versus time data and model the data as a linear function. They also examine the concept of slope...

In this polymer worksheet, learners make two types of cross linked polymers and they test their physical properties. These include their response to agitation, stretchability, viscosity, and resilience.

Students use short-chain polymers and borate ions to produce cross-linked polymers in the lab. In this cross-linked polymer lesson plan, students produce polyvinyl acetate slime and polyvinyl alcohol slime and test their physical...

Fourth graders identify the attribute of volume of an object. Units of measurement are reviewed and utilized in this instructional activity.

Second graders analyze the effects of sunlight on a glass of water by using the thermometer to measure its temperature. They predict and measure the difference between water outside in the sun and shade and inside. They role-play a game...

Second graders study how actions in the schoolyard and home can affect water quality. They discuss how rainwater can clean plants and sidewalks on its way to storm sewers. They draw an example of a simple maze that represents the maze...

In this water desalinization worksheet, students will design and construct their own desalinization plant. Then they will describe how they set up their experiment and if it worked or not.

In this classification of matter learning exercise, students answer 15 questions about solids, liquids and gases, types of mixtures and compounds vs. elements. They also answer 2 questions about measurement and 1 question about a biome.

In this density activity, students use the mass of aluminum and copper at different volumes to create a graph in order to calculate the density of these metals. This activity has 1 graph, 2 short answer, and 5 word problems.

In this density worksheet, high schoolers review this property of matter and the mathematical equations for density, mass, and volume. The worksheet has 10 fill in the blank statements and 3 word problems.

In this basics of science instructional activity, students review the metric system, the difference between homogenous and heterogenous mixtures, the scientific method, and science lab first aid. This instructional activity has 15 short...

Students watch video, The Elements, research information about elements using both the Internet and CD-ROM program, and create atoms out of gumdrops and licorice.

Learners are introduced to basic engineering principles, road construction and material science. They explore how material properties and strength can be affected. Students become Civil Engineers by both creating Asphalt cookies and by...

In this chemical reaction instructional activity, students are given the details of an experiment where sodium chloride and silver nitrate are mixed in a chemical reaction. Students answer nine questions about the chemical reaction, they...

Students investigate diffusion using different solutions of chemicals placed in agar dishes. In this diffusion lesson plan, students observe 3 demonstrations of diffusion using perfume, food coloring in water and sugar cubes in water....

Third graders investigate why ice cream does not go through any chemical changes when it is exposed to physical changes. They describe the three states of matter in either written or verbal form. Then students experiment with ice cream...

Fourth graders explore whether the making of homemade ice cream is a physical change or a chemical change in a lab experiment. Students identify states of matter, describe the physical properties of states, and collect temperature data...

Students observe the 'pouring' of a gas. They compare the masses (weights) and densities of two gases. Pupils define the following terms: matter, mass, and density. Students answer questions after watching the demonstration.

Students list reasons why water is important and investigate and graph the freezing points of different solutions.

Students measure the rainfall/snowfall on the playground on a rainy/snowy day with a rain/snow gauge. They draw a bar graph representing the amount of water that fell and observe a satellite image of the clouds and local weather system...

Students discuss and experiment with the phases of water.  In this phases of matter lesson plan, students recognize the different states of matter.  Students measure and record changes and understand when the state changes.

Eighth graders, in groups, explain the difference between physical and chemical changes.

Students observe and describe, both orally and in writing. the different forms of water on the surface of the Earth and measure the approximate size of an iceberg. They also estimate and measure the amount of ice that floats above the...
