When your upper elementary or middle school class is learning about chemical changes, these activities help demonstrate the concepts. In Part A, they submerge and place a nail partially underwater, then after a week they make...

Little chemists observe the effects of acid on calcium carbonate as an example of chemical change. As a demonstration you will place a raw egg in vinegar overnight, and as a lab activity, learners drip vinegar onto a piece of chalk....

Students identify the signs that a chemical reaction took place. In this chemistry lesson, students role play the movement of different molecules of matter. They classify matter according to their properties.

The fourth activity in a series of five has classes participate in a jigsaw to learn about global impacts of climate change and then share their new information with a home group. Groups then research impacts of climate change (droughts,...

Scholars become experts on the eight major impacts of climate change through a jigsaw and grand conversation. They then research and present what they learned about effects specific to their region.    

Students see evidence of chemical reaction and follow the scientific method to hypothesize, observe, and reach conclusions. They conduct a series of egg based experiments such as forming crystals and complete journal activities as a...

Students define the words "reversible" and "irreversible." They complete a worksheet that shows a number of changes. Students must decide which are reversible and which are irreversible.

All synthetic materials began as natural materials. An engaging lesson begins with a hands-on activity and an example of the type of research that scholars perform independently. Then pupils receive a topic and begin researching the...

Fifth graders evaluate evidence that indicates a physical change has occurred. In this colonial living lesson, 5th graders explore the science involved in the making of items used in colonial life, such as, bread, butter, soap, candles,...

Students 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.

First graders discover that a chemical reaction is responsible for the effects seen with Crayola Color Wonder markers. They observe that the color changes are the result of a chemical reaction between chemicals in the Color Wonder paper...

Fourth graders observe what is happening when an Alka-Seltzer tablet is placed in a clear cup of water. They observe the release of carbon dioxide gas. Pupils answer the question of how much as is released by observing the experiment...

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

Third graders conduct experiments in matter to create chemical changes resulting in gases. By mixing solids and liquids, they create a chemical reaction and capture the gas in balloons. After observing the balloons fill with carbon...

Students examine the gold-mining industry in Africa. In this geography skills instructional activity, students watch "Africa: Economics and Change," investigate the challenges of working in mines, research attributes and production of...

Third graders explore forms of matter through reading, hands-on science activities, and research using the Internet. Students create a booklet, directions given, that they title and decorate, to later serve as a review visualization...

Learners explore climate changes. In this climate changes lesson, students research what causes changes. Learners search the Internet, summarize reports they find and create a poster with the information.

Fifth graders develop a deeper understanding of chemical and physical changes. They explain how salt is made, used, and the affects it has on the body. They explain that salt in moderation is important to our health.

Students know that participation in sports requires energy. They comprehend that we get energy form the foods that we eat and the air thta we breathe. Converting food and air into usable energy is defined as celluar respiration. Students...

Students test pH of water before and after it travels through different substrates (igneous pebbles and limestone) to detemine how soluble materials can affect groundwater. They answer questions such as: What happended to the pH of the...

Students describe the history of materials. They use the kinetic (particle) theory to explain changes of state in matter and trace the flow of heat during changes of state and chemical changes.

Students engage in a lesson that is concerned with the concepts related to solution chemistry. They calculate the molar mass of various chemical compounds. Then students predict the anion ratio for ionic compounds. Students also write...

Students analyze the relationship between density, buoyancy, and salinity. In this chemical properties lesson, students read a background activity for the lesson and experiments to the topics. Students discuss the questions and complete...

Students review some examples from the website "We Are What We Do" and examine the impact of lots of people making small changes to their lifestyles. They complete a worksheet to introduce them to the variety of challenges. Students...
