Get down to basics with these worksheets on the structure of atoms. Challenging young chemists to identify information from the periodic table and create Bohr diagrams and Lewis dot structures for different elements, this...

Students practice addition and estimation. They use tens models to solve the problems related to grocery bags and Earth Day. Afterwards, they complete an activity sheet and draw a large grocery bag decorated with Earth Day messages.

Middle schoolers imagine they are a detective who has been asked to solve the theft of cookies from a jar in the student cafeteria. Students practice using the steps of the scientific method to solve the crime. Finally, middle schoolers...

Represent motion with arrows and call them vectors! The lesson is a presentation that models the mathematics involved when determining a resultant vector. It addrssses motions that are parallel, perpendicular, and a combination of...

In this chemical reactions worksheet, students review the oxidation number rules and then assign oxidation numbers to atoms in given compounds. Students identify the reducing agent and the oxidizing agent in reactions. Students practice...

In this 2-day lesson focused on exponents, middle schoolers will cross the curriculum by engaging in science, history and language arts activities. Exponential growth will be explored using grains of rice on a chess board. Exponential...

Food always gets attention! Model atomic structure using fruit loops to represent the subatomic particles. After building models, scholars create ionic bonds using their models. Finally, they use these concepts to create a periodic...

Students play an interactive activity and answer questions about body systems.

Students examine the different systems of the human body and how they work independently and cooperatively. They complete sevral online interactive projects designed to reinforce how the systems work alone and together. Students make...

Young scholars explore the forms of water. In this physics lesson, students use ice cubes and observe what happens when the ice melts. Young scholars freeze the water again and record observations.
