"Tree Cookies!" is a delicious little presentation designed to introduce upper elementary or middle school botanists to the anatomy of a tree trunk. The cambium, phloem, xylem, and other vital structures are identified and defined. Two...

Dry ice is extremely cold — it is -109.3°F or -78.5°C. Scholars observe and explain the molecular motion associated with melting. Then they design their own experiments to speed up the melting process. Finally, a teacher presents a...

There are five types of frost: ground frost, air frost, hoar frost, glaze, and rime. Scholars mix ice and salt in a metal container to observe frost forming on the outside of the can. Animations and videos enhance the learning. 

An excellent, in-depth resource would be an asset to your unit on writing an argument essay. It provides an explanation to each part of the essay as well as examples of transition words to strengthen your kids' writing. Additionally, the...

Trying to plan an engaging elementary science unit on natural resources? Conserve your energy! This five-part series of lessons and hands-on activities has exactly what you need to teach young scholars about the importance of conservation.

Mix it up at a party as Sam and Zoe discuss heterogeneous and homogenous mixtures and solutions. Follow this film by allowing your class to put together individual snack foods to make their own mixture!

In a friendly, casual conversation on the beach, two animated teens discuss the periodic table. Assign this video to be viewed at home by physical science fans. After viewing, they can write definitions for key vocabulary terms and take...

The first STEM lesson in a group of 10 explores composting. After discussing how to make a better tomorrow, classes are challenged to track garbage in their communities, visit a local waste management facility, and conduct a survey...

Plasma is the most common phase of matter in our universe. Scholars explore the change of energy as molecules change phases of matter. They rotate through stations, graphing the changes in energy level.

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...

Second graders identify and describe basic geometric solids. Working as a class, 2nd graders describe geometric solids using the proper vocabulary and counting faces, bases, corners, and edges. In pairs, students use a computer drawing...

Learners complete activities to learn a phenomenological approach to polygons. In this polygons activity, students use the materials in the directions to make demonstration models. Learners use a wooden wagon model and liquid to learn...

Students identify and correctly name three-dimensional solids; cones, spheres, and cubes. In this three-dimensional figures lesson, students  build a cube by matching colored square faces to a correct word. Students then...

First graders categorize matter. They compare how solids and liquids behave.

Second graders discover that everything is made of matter. they determine the properties of liquids and that like solids, liquids can be grouped or classified according to properties or qualities. they assess that solids have a definite...

Students explore the three states of matter. For this physics lesson, students are shown examples of solids, liquids, and gases. Students make cookies and identify the three states of matter during the baking process.

First graders create ice cream in class.  In this matter activity, 1st graders discover solids, liquids and gases and the properties of each.  Students produce a batch of ice cream in class using household items.

Students explore matter by conducting an in class demonstration. In this liquid mixture lesson, students identify the difference between a solution in which a solid dissolves into liquid, and a suspension where the solid doesn't dissolve...

Second graders identify three forms of matter- solids, liquids, and gases with 100% accuracy. They observe water evaporating from an open container and water evaporating and condensing in a closed container. The students assess that a...

Students recognize the importance of solid waste management. In this science lesson plan, students analyze individual solid waste management habits as they enhance their knowledge of solid waste disposal and the recycling process.

Students analyze and evaluate evidence that matter is made of tiny particles. They observe a series of phenomena involving solids, liquids, and gases to make inferences about the spacing, interactions and relative kinetic energies of the...

Students expand their understanding of solid waste management. They examine the effects of packaging decisions. They study engineering advancements in packaging materials and solid waste management.

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...

Students read Bartholomew and the OObleck by Dr. Seuss and experiment with solids and liquids.  In this science and reading instructional activity, students observe and discuss the properties of liquids and solids.  Students...
