Second graders discuss why some objects float while others sink. They examine various objects and predict whether or not they will sink or float. Students discover the properties needed for objects to float.

Students identify the various states of water. They use hypothesizing and hands-on experimenting on changing the states of water, the properties of water, and the role of heating and cooling in the changes of state.

Students experience problem-based learning as they use prior knowledge of the states of matter to keep a frozen juice bar from melting.

Students observe the diffusion of air molecules through a balloon. In this chemistry and molecules lesson, students fill balloons with air and a scented substance and observe whether the scented air is able to permeate the balloon.

Students examine how a hot air balloon works. In this hot air balloon lesson, students do an experiment to test the effects of heat on density. Students make their own hot air balloon and act out how nitrogen moves when turned to a liquid.

Students experiment with objects of different densities. In this density lesson, students examine same-sized objects with different weights, then look at a teacher explanation of density. Students make wave bottles and a density jar to...

Students observe the 'pouring' of a gas. They compare the masses (weights) and densities of two gases. Pupils define the following terms: matter, mass, and density. Students answer questions after watching the demonstration.

Students use funnels to put the five solid materials into clear bottles with caps. They observe how the particulate materials look, sound, and move when they shake and roll the bottle. Finally, students write "sound and touch" poetry.

In this heat transfer and phase change worksheet, learners experiment with ice, salt, and milk to show the relationship between the temperature of a solution and its phase. Students turn milk from a liquid to a solid and graph the...

Students study how matter changes from solids to liquids or liquids to solids. In this physical science lesson, students discuss heat energy and experiment with heat by changing a candle into a liquid using a hot plate.

Learners explore the properties of matter.  In this cross curriculum three states of matter science lesson, students listen to the poem "Eighteen Flavors" by Shel Silverstein, and predict what will happen if listed ingredients are...

In this thermochemistry instructional activity, learners indicate whether the given processes are endothermic or exothermic reactions. Students complete the phase change diagram as well as define a given set of vocabulary words. Learners...

First graders understand that gases take up space even though you can't see or smell it. This is done through many experiments like trapping air in different sized bags, using balloons and plastic bottles, and blowing bubbles. They...

Students identify the different states of matter. In this chemistry lesson, students differentiate the physical properties of the three states. They apply what they learned by playing a team game at the end of the lesson.

Second graders discover how matter changes from one state to another by observing melting ice cubes. They decide on means to warm the ice and predict what will happen. Students record how long it takes for the cubes to melt.

Calories are not tiny creatures that sew your clothes tighter every night, but what are they? A science lesson, presented at multiple levels, has learners experiment with heat, heat transfer, and graph the function over time....

Entropy, it isn't what it used to be. Presentation includes kinetic-molecular theory, heat and internal energy, thermal equilibrium, temperature scales, laws of thermodynamics, entropy, latent heat of fusion, specific heat, calorimetry,...

In this physics worksheet, students determine the density of irregular solids using water displacement method to complete 7 problems and short answer questions.

Students complete a unit to learn about sound; students include multiplication and division problems along with rate problems. In this sound lesson, students complete 7 separate lessons with multiple activities to learn about sound.

First graders break into groups of five students and are given 15 different objects and 3 posters. They group the objects into 3 different families with all the objects in each category placed on one of the posters. They choose whatever...

In this matter worksheet, students watch a movie and then compare the differences between compounds and mixtures. This worksheet has 16 fill in the blank questions.

Third graders rotate between three property stations, the solid station, the gas station, and the liquid station. They experiment with each activity until the teacher gives the signal to change.

Second graders listen to a teacher read aloud introducing a unit about how water changes state. They investigate the state of water as it changes from a solid, to a liquid to a gas.

In this heating and cooling curve instructional activity, students use a given graph of a substance being heated from a solid to a liquid and then a gas over time. They use the graph to answer eleven questions about the phases of the...
