For this scientific methods worksheet, high schoolers compare independent and dependent variables, hypothesis and theory, homogeneous and heterogeneous, and physical and chemical change. This worksheet has 17 short answer questions.

In this matter worksheet, students read statements about changes happening to matter and classify the change as either a physical or a chemical change. This worksheet is a graphic organizer.

Students identify the functions of packaging food and how the designs work.  In this food packaging lesson students identify the changes that occur in different types of materials. 

In this chemical change worksheet, students review physical changes such as evaporation and condensation before working with chemical change. They conduct an experiment with vinegar and baking soda before recording the chemical changes...

How are chemical reactions affected by gravity? Learners explore the phenomenon of effervescence as part of the Christa's Lost Lessons series. They compare findings in an experiment on effervescence to a video of a similar experiment in...

Climate models mathematically represent the interactions of the atmosphere, oceans, land, sun, surface, and ice. Part two in the series of four lessons looks at the role greenhouse gases play in keeping Earth warm and has participants...

Conclude this chemical change unit by having your class combine two liquids that result in formation of a precipitate. The learners discover that chemical reactions result in new materials. Make sure to consider all of the preceding...

In this chemical and physical change worksheet, students determine if 5 statements are examples of chemical or physical changes. At home they find 1 example of a chemical change and 1 example of a physical change. They explain why each...

For this chemical reactions worksheet, students compare physical changes and chemical reactions. Students learn to balance chemical equations. This worksheet has 10 short answer questions.

If you are willing to sort through this outline and overlook the portions relating to inaccessible videos, you will find a wealth of support for your introductory chemistry unit. Narrative is presented to help you help learners navigate...

Fifth graders evaluate the physical properties of 5 powders. Each powder is subject to different conditions. They describe each observation as with a chemical change or a physical change.

Students explore mechanical and chemical weathering at stations. They articulate some mechanisms of chemical and mechanical weathering through exploration in a lab. Students stations describe how chemical weathering differs from...

Excite classes with a STEM project-based learning lesson covering chemical reactions. Groups study the different types through simulations and hands-on activities. They pick one type (synthesis, decomposition, single displacement, double...

Create a little scientific magic within your classroom! Learners mix powders and liquids and identify chemical reactions. Based on the reactions, individuals determine the identity of various powders.

Learners examines the arctic food web with a short video about polar bears and an article about bears and warming temperatures. They design an arctic food web and discuss the trophic cascade that could come from climate...

What does size have to do with it? Learners analyze different mixtures, both homogeneous and heterogeneous, to discover the properties related to the size of their particles. The activity connects these properties to those of...

Fifth graders examine the differences between chemical and physical changes. As a class, they are read a scenerio and determine whether it was deliberate act or not. In groups, they observe the changes of an alka-seltzer tablet and...

In this chemical reactions worksheet, students answer follow up questions to a lab where they were observing chemical changes in reactions after mixing products such as hydrochloric acid and sodium bicarbonate. They answer six questions...

Students illustrate the molecular nature of matter and show that chemical change involves alteration of molecules.

Students are introduced to two changes, physical and chemicl, in order to prepare them to comprehend what changes take place in a Winogradsky Column. They participate in two activities including completion of a worksheet, balloon...

Can you disprove the law of conservation of mass? Pupils observe the teacher weigh each part of a reaction. Then, the teacher weighs the result of the reaction and everyone sees that the products do not equal the reactants. Then they...

Is your class in the dark about photosynthesis? Shed some sunlight on an important biological process with a thoughtful activity. After answering questions to help determine their level of knowledge, learners work with chemical equations...

From gas to liquid condensation to solid frost, water undergoes phase changes before students' eyes! Using ice, salt, water, and a metal can, they set up an investigation that can be used in a physical science setting, or as part of a...

It's time to break the ice! If you are doing all of the lessons in the unit, children have already seen that increasing heat increases the rate of evaporation, but is the opposite true? Does decreasing temperature cause more condensation...
