Students describe how elements are arranged on the periodic table. They compare metals, nonmetals, and metalloids based on their properties and on their locations in the periodic table. Students describe the differences between a...

In this chemistry worksheet, learners find the words that are related to atoms and molecules. The answers are found by clicking the link at the bottom of the page.

In this space science worksheet, students find the words associated with the basic terms of Astronomy. The answers are located at the bottom of the page.

In this ages of rock learning exercise, students review the processes involved with determining the ages of rocks which includes the radioactive decay of carbon-14. This learning exercise has 5 matching and 5 short answer questions.

For this atoms activity, high schoolers compare sub-atomic particles' position, relative charge, and relative mass. High schoolers define mass numbers and atomic numbers. This activity has two graphic organizers and four short answer...

In this problem solving worksheet, students are given five problems including calculating volume given the dimensions of a pool, determining the number of subatomic particles in an atom, filling in a table with chemical names and...

Learners explore the meaning of density. For this density lesson, students use interactive whiteboards to review definitions regarding density and compare the density of selected objects.

Students read passages and view a slide show on the theory of evolution and provide evidence that this theory is correct. In this evolution lesson plan, students read about fossils, anatomy, organs, fetal development, and more.

Ninth graders perform a series of experiment to investigate heat transfer and phase changes. In this physical science lesson plan, 9th graders identify and calculate the different subatomic particles. They explain the importance of...

In this mineral worksheet, students give the name and/or symbol for elements and they distinguish between elements and compounds. They fill in a chart with subatomic particles for given elements and they determine if given substances are...

Students investigate the atom and how it is formed. They conduct research using a variety of resources and then construct a model of the atom. Then students have class discussion. The lesson includes background information for the...

Middle schoolers read an article about radon and its properties. They examine a periodic table and identify the numbers surrounding an element. They discuss the harmful and helpful effects of radiation.

Students examine what radon is and which isotope it belongs. They discuss the characteristics of isotopes in general and the atomic number. They complete a worksheet to complete the lesson.

Learners practice drawing the atomic structure of several different elements. They complete critical thinking questions about atomic structure and compare the atomic mass units for different ions and isotopes of an element.

Young scholars identify the different periodic trends. For this chemistry lesson, students discuss how elements are arranged in the periodic table. They apply what they have learned in a Jeopardy team game.

Young scholars explain how elements are arranged in the periodic table. In this chemistry instructional activity, students group the eggs according to a certain pattern. They compare this to elements in the periodic...

Fourth graders use circles to "home in" on particular spots, showing the ability of scientists to locate unseen objects in space. This activity shows how scientists know certain objects exist in space due to the forces exerted by...

Sixth graders explore and discuss how several electrical devices work and what energy conversions occur in each device. They connect a zinc strip to a copper strip with alligator clips and wire, immersing each strip in lemon and check...

For this elements worksheet, students review the periodic table and how the elements are organized in the periodic table. This worksheet has 5 short answer and 4 fill in the blank questions.

Young scholars parcticipate in a modeling activity that simulates the cyclical role of experimental and theoretical science. Initially, students measure the mass of popcorn. They also record predictions of the mass of the kernels after...

Students identify how to relate the position of an element in the periodic table to its atomic number and atomic mass. They also identify and interpret how to use the periodic table to identify metals, semimetals, nonmetals, and...

Young scholars experiment to show their knowledge of molecules and atomic structures.  In this chemistry review lesson students participate in an activity and then fill out a worksheet.

An interesting and useful tool to practice recognition/calculation of atomic number, mass, and number of neutrons, electrons, etc. Can be used with all elements.

Find out if you know enough about atoms to build them. The goal of the activity is to build an atom of a particular element by dragging the correct numbers of neutrons, protons and electrons into the atom.
