Young scholars experiment with solids and liquids. For this mixtures of matter lesson, students combine matter to form solutions. Young scholars hypothesize, test, and analyze the data to draw conclusions. The lesson can be extended by...

Fifth graders examine both physical and chemical changes, and how to identify the difference between the two. They observe the changes that occur in butter when it is exposed to heat and cold, heat energy. In their notebooks, they write...

Fourth graders explore physical changes and the true life story of Wilson Bentley. They observe the changes that take place with snowflakes. Students discuss what happens when snow flakes melt. They create their own snowflakes using...

Students investigate water in its solid and liquid form. In this states of matter lesson, students experiment to see what happens as water goes from a solid, ice, to a liquid, water, and back again. They write about and illustrate the...

Students study the flow of water in the environment.  In this water cycle lesson students evaluate the consequences of changes in the water cycle using data. 

Students look for examples of chemical and physical changes in the world around them and complete "What's Happening in My World" worksheet.

Fifth graders investigate chemical reactions. In this physical science lesson, 5th graders make dry ice root beer and identify the type of change that occurs to the root beer mixture.

Learners study the amount of potable water on the Earth. In this water instructional activity, students examine the amount of potable water as compared to all the water on the Earth. They discuss why many parts of the world do not have...

Fifth graders compare physical and chemical changes. They perform a simulation experiment/activity that replicates what happens in the stomach as food is digested by stomach acids.

Students enclose water in an airtight bag and leave it in a warm area to view the water cycle. For this water cycle lesson plan, students observe evaporation, condensation, and precipitation. They then discuss what they learned about the...

Fourth graders study and identify the basic needs of a variety of organisms. Terrariums and aquariums are used to demonstrate what plants, animals, and fish need to stay alive. These two classic models are used to effectively convey what...

Learners explore physical science by participating in a water properties experiment. In this surface tension lesson, students utilize pennies, water, a dropper and soapy water to test the different surface tensions with numerous objects....

An interesting way of teaching about basic needs of different organisms awaits your fourth graders. Pupils take part in class discussions and demonstrations which should lead to a greater understanding of how to determine basic needs. As...

In this Newton's 3 laws of motion worksheet, students view examples of each law and draw 1 example of each law on their own. Students draw 3 pictures.

How much does the sun heat up a lake or ocean? Scholars use a cup and a strong lamp to investigate the heat transfer and thermal layers in the ocean to come up with the answer. They collect data and graph it in order to better understand...

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...

At a depth of 3,000 m in the ocean, the pressure is 300 times that at sea level! In the activity, individuals predict what will happen to Styrofoam cups submerged 3,000 meters into the ocean. They then convert these units to soccer...

There's a container for every matter—liquid, solid, and gas. Pupils design three different containers, each with the capability to hold one of the states of matter, and share their design with the class.     

There are so many topics touched upon in this Jeopardy-style science game, that it is difficult to classify! The categories include electricity, matter, ecology, earth and space, and scientific investigation. This would best be used at...

Students discuss the definitions of physical and chemical properties and changes. They vaporize a solution of salt and water, observing the sodium chloride that is left behind.

Students explore the states of water. In this water states lesson, students observe ice over time and the changes that take place. Students read a related text and draw their observations in a journal entry. Students discuss the...

Playing with balloons, water, oil, and bottles help put this instructional activity over the top! Participants use air-filled balloons in water tanks to experience gas compression. They also use oil-filled bottles to experiment with...

Young scholars find the density of diet soda and regular soda. In this density lesson plan, students measure the mass of a graduated cylinder with 10 different volumes of each soda. They find the mass of the liquid alone and use the...

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.
