After challenging themselves to correctly choose the form of erosion and length of time required for a given landform to develop, earth science class members model mechanical and chemical weathering with various lab demonstrations over...

When you don't follow the rules, bad things can happen! Kick off your next lab safety lesson using a resource from the K20 Center. Pupils partner up to decipher MSDS for common lab chemicals, brainstorm common safety rules and their...

Young scientists investigate chemical and physical changes to the states of matter—gas, liquid, and solid—as well as solutions and suspensions with a variety of demonstrations, grand conversation, and an interactive quiz to check for...

Students observe the differences between physical and chemical changes in properties. Through the use of an interactive presentation, the students compare and contrast the changes and provide supporting examples of each type of change.

When a candle burns down, what happens to the mass that appears to be shrinking? Lesson begins with a demonstration of the chemical reaction of a candle burning. Then scholars use atom models to observe conservation of mass...

Sugar crystal growth is observed as an example of physical change and cabbage juice pH indicator is used to demonstrate chemical change. The crystal growth is tracked over five days. The cabbage juice experiment is involved and can also...

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...

Students explore physical and chemical changes. In this chemistry lesson plan, students will go outside to observe changes seen in nature. Students will then work in the lab to identify changes at different stations prior to doing a...

Students explore chemical cahnges and the effect of temperature on chemical mixturees, They make observations of the behavior and appearance of certain chemical mixtures and reactions.

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.

Imagine a race to complete a puzzle where each person has the same 50 pieces, knows they are missing other pieces, and must figure out how everything fits together. The winner gets fame, listed in books for years to come, and a financial...

We all know limestone weathers, but what affects the rate of weathering? Young scientists investigate the physical and chemical weathering of limestone (chalk) through experimentation. First, they conduct trials with different-size...

Sixth graders explore, analyze and study the effect and impact that humans have on the environment based on their choices as individuals, businesses and governments. They assess the balance between human activities and aquatic pollution.

Eighth graders observe two types of interactions in a sealed plastic bag. One bag contains baking soda and water, and the other baking soda and vinegar. They determine what evidence indicates that a chemical change is occurring.

Students measure the effect of water temperature on the rate of a chemical reaction, similar to the interaction of a weak acid and carbonate rock, using hot water and effervescent antacid tablets.

Students study the difference between physical and chemical properties. They also discuss changes in matter, known as physical and chemical changes. They observe and discuss several demonstrations of both physical and chemical changes

Students research five types of chemical reactions in order to design a learning center. Students use technology to research and present their material.

Students investigate the art and science of pyrotechnics.  In this chemistry and computer lesson plan, students learn about the chemical basis of fire and structure of fireworks.  Students then apply their knowledge...

Household materials can be used for more than cleaning! In this collaborative experiment, emerging chemists use products such as vinegar and liquid antacid to explore chemical reactions that commonly occur in the human body.

Students investigate matter. In this physical science lesson plan, students will learn about matter, physical states, and reactions. There are a series of four lab activities that will be conducted.

Students explore the field of chemical engineering and identify the contributions of chemical engineers to society. They explore how chemical engineering is like and different from the other engineering professions. They study the...

Students study how to balance chemical equations.  In this investigative instructional activity students work on how to balance chemical equations. 

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...

Energy is just energy, right? Explain various forms of energy to your young scientists by using an interactive experiment that contains common objects to demonstrate complex concepts. Pupils conduct experiments for radiant, thermal,...
