Super scientists visit ten stations to predict, observe, and draw conclusions about the physical and chemical changes that occur when different states of matter—liquid, solid, and gas—are placed under a variety of conditions. To...

Whoa! What just happened? That's right, change is everywhere. But what exactly is changing? Middle school science sleuths get to the bottom of the changes matter can experience. Through simple demonstrations, engaging videos, and an...

Fourth graders investigate chemical changes in everyday life settings, such as cooking. They investigate leavening which is one of the classic chemical changes that people experience. Pupils observe leavening in biscuits with the...

Alia-Seltzer tablets cause a very obvious chemical change, but do they also cause a temperature change? Each class member explores hot/cold packs, discussing how these temperature changes occur. Groups then design and carry out their own...

Third graders investigate how temperature and motion (energy) create a chemical change that turns cream ( a liquid) into butter (a solid). They create a class pictograph of their favorite mils choices (white, chocolate, or strawberry)...

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.

If you discover an unknown powder, how do you determine if it is safe? Lesson uses four different tests to identify the properties of various powders that appear the same. Then scholars get an unknown powder and have to determine which...

Students distinguish between physical changes and chemical changes. They comprehend that chemical reactions produce new substances with compositions and properites which are different than those of the starting materials. Pupils also...

The more things change, the more they stay the same. This unit includes seven lessons starting with physical change and moving through to chemical change. Conservation of matter is explained clearly with multiple hands-on activities and...

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 analyze the causes of corrosion. For this chemistry lesson, students investigate what is necessary to cause chemical changes in matter. Students discover the causes of rust and tooth decay.

Ready to take your chemistry class on its first big lab adventure? Dive in to differentiation between chemical and physical changes with a thoughtfully designed set of experiments! Partners conduct a series of reactions, describe their...

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...

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...

Construction leads to habitat loss and local wildlife suffers. Scholars must build a reptile egg incubation device that meets many constraints. Various experiments help them discover the chemical reaction needed to reach...

My room isn't messy — it's a scientific experiment in entropy! Scholars investigate entropy, enthalpy, and spontaneity through a guided procedure and set of questions. The lesson connects the Second Law of Thermodynamics, energy...

Bring A Charlie Brown Christmas to social studies, language arts, math, science, and art class! Learners ponder the meaning of Christmas trees, write about Christmas during the original release of the television special,...

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.    

According to the Mauna Loa observatory, carbon dioxide levels increased by 3 ppm in our atmosphere between 2015–2016. Individuals analyze carbon dioxide data from around the world and then share this with a home group in lesson...

Fourth graders expand their knowledge about how the physical properties of a substances can be changed. They are given multiple opportunities, using first-hand experiences and familiar objects in different contexts, to identify...

Sixth graders complete several experiments about chemical and physical changes. In this physical and chemical science lesson, 6th graders complete 6 experiments about chemical and physical changes. Students examine the processes of...

Young scholars 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...

Only 10 percent of an incandescent bulb's energy is used to create light; the remaining 90 percent is heat. In the unit of activities, young chemists examine energy through hands-on activities, videos, discussions, and...

How long do fresh foods last in space at the International Space Station? Which foods perish quicker than others? How can astronauts preserve their foods to make them last longer in space? Young scientists test the rates at which...
