In this mixtures pre-lab worksheet, students compare and contrast suspensions and colloids and solutions and colloids. Students describe the Tyndall effect. This worksheet has 10 short answer questions.

Learners recognize both a physical and chemical change in different substances. They determine which particles actually changed into different substances, and explain if it represented a physical or a chemical change.

In this leaf chromatography worksheet, students separate the pigments of a leaf using paper chromatography. They answer 4 questions about their results and draw the colors they observe on their chromatogram from the leaf.

In this solutions worksheet, students read about solutions, solutes, and solvents. Students compare solutions with mixtures that are not solutions. Then students complete 10 fill in the blank, 12 matching questions, and 10 terms into a...

In this solutions learning exercise, learners read about the characteristics that define a solution such as the solvent and the solute and the homogeneous mixture. They are given a chart with the differences between solution, colloids...

In this chemistry review worksheet, students answer a variety of questions about matter, elements, the kinetic theory, chemical and physical properties and the distillation process. They complete a concept map about matter.

Eighth graders analyze physical change in mass. For this chemistry lesson, 8th graders describe, measure and calculate the amount of physical change occurring in mass before and after the change. Students should be familiar with...

Second graders explore weathering and how the water cycle plays a part in weathering. In this weathering lesson plan, 2nd graders put gravel and sugar cubes in a jar and shake, simulating weathering. Students use the scientific...

Learners explore the technique of chromatography to separate compounds in a mixture. In small groups, they separate by paper chromatography and identify the major and accessory photosynthetic pigments.....................................

Students explore the properties of matter.  In this cross curriculum three states of matter science instructional activity, students listen to the poem "Eighteen Flavors" by Shel Silverstein, and predict what will happen if listed...

High schoolers construct their own lava lamp using simple substances. In this physics lesson plan, students explain how difference in density causes convection. They solve for forces and buoyancy using mathematical equations.

Students analyze soil for types of pollen to determine the probably climate conditions. In this earth science lesson, students make conclusions on what a climate is like based on soils samples. Students use a model soil...

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

Learners 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...

Learners conduct an experiment that shows them how salt water allows things to float. In this salt water lesson plan, students mix ingredients together to create salt water and observe how it makes the oceans dense. They then interpret...

A 12-page midterm exam sample can be given to young scientists in preparation for an exam. This particular installment is geared toward a class that delves into both ecology and chemistry concepts. There is no way to separate the 50...

Students construct a water filter. In this engineering lesson, students discover how to construct a water filtration system. Students work in groups to sort tools by their properties. Students analyze and construct a water filtration...

A tremendous presentation on the properties of light. Young scientists are treated to slides which share a lot of fascinating information about light. This impressive PowerPoint is filled with great photos, graphics, and discussion...

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 perform tests on different chemicals to determine their chemical properties. In this forensic science lesson, students identify an unknown sample using its physical and chemical properties. They solve a fictional crime using...

Students develop a pathogen based upon their knowledge of pathogens and after presenting it to the class, they then suggest ways that the pathogen might be combated. Next they identify possible physical or behavioral changes in a...

In this minerals worksheet, students will review the four physical characteristics used to identify a mineral: streak, color, size, and hardness. Students will also understand the Mohs Hardness Scale. This worksheet has thirteen short...

It might be silly to determine the creep rate of putty but groups will enjoy making different formulations of silly putty and playing with them to understand how the different mixtures behave. The second part of the activity has groups...

In this matter worksheet, students compare the different types of matter, including the states of matter. Students review the metric system. This worksheet has 12 matching, 18 fill in the blank, and 4 short answer questions.
