Young scientists learn that seeing isn't necessarily believing when it comes to the states of matter. After performing a fun class demonstration that models the difference between solids, liquids, and gases, children complete a series of...

Learners explore the concept of evaporation rates in this evaporation rates lesson. They will try to identify the chemical that began a fire, perform an experiment where they use the evaporation rates to determine the unknown liquid, and...

Students observe liquids in different containers and then explore the concept that liquids have level surfaces. They identify those who are not at the center to reinforce the concept of liquid levels with a representational puzzle and...

First graders observe examples of the three states of matter and identify matter in each of the three states. They make glitter wands to remind them of the three states of matter: solid, liquid and gas. Pupils brainstorm and record...

Students study the vocabulary of the states of matter. In this states of matter vocabulary lesson, students investigate and study the meaning of the words solid, liquid, and gas. They experience demonstration lessons that give them...

Students investigate what matter is and how it changes states.  In this physical properties instructional activity, students examine the vocabulary database and identify the characteristics of the three phases of matter....

Young scholars explore how sound waves move through liquids, solids and gases in a series of simple sound energy experiments. They describe how sound needs molecules to move and that changing the medium that it travels through changes...

Students analyze earth science by creating a frozen treat in class. In this heat transfer lesson, students discuss how matter is transformed from solid to liquid and liquid to gas when energy is removed from the equation. Students...

Students explore liquids and solids by conducting in class experiments. In this matter lesson, students define the properties of matter and how heat can change those properties. Students experiment with heating objects such as butter and...

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.

Students use standard rulers to measure the length of common classroom items - such as pencils, books, desk tops - in inches and centimeters, and measure weight in pounds. They also answer math questions, such as "How long is the front...

Students use screens of three sizes to separate a mixture of five solid materials. They plan and conduct simple investigations using appropriate tools, measures, and safety rules and record and report observations, explanations, and...

Whether you're using a collection of Dr. Seuss books to teach basic math skills like counting, adding, and subtracting, or exploring the different states of matter by melting a crayon with a hairdryer, a series...

Young scholars explore global warming by conducting a weather experiment. In this greenhouse gas lesson, students define the greenhouse effect and the impact on our ozone layer. Young scholars utilize a soda pop bottle, floodlight bulb,...

Whatever floats your boat. Young engineers learn about density by measuring the masses and volumes of boxes filled with different materials. Using their knowledge of densities, they hypothesize whether objects with given densities will...

Young scholars study the scientific evidence about carbon dioxide emissions. They learn to calculate the amount of energy used by different appliances. They complete a worksheet which analyzes the amount of energy that their home uses.

Third graders review ideas about sound and vibration to make their own stringed instrument. They review what a pictograph and bar graph are. Pupils conduct a survey within the classroom to choose the four favorite string instruments and...

Students follow a recipe to make ice cream. In this ice cream lesson plan, students make their own ice cream by measuring out ingredients and following directions.

Second graders explore how seasonal weather patterns affect temperature and their lives.

Pupils explore linear functions in this instructional activity when they collect and analyze data as a chemical reaction proceeds. Learners record pressure versus time data and model the data as a linear function. They also examine the...

Second graders review the weather through a role-playing game.
