In this atomic theory activity, students review the observations that led to the conclusion of the atom having a positively charged nucleus. Students compare atomic number and mass number and explain how the discovery of subatomic...

In this atom worksheet, learners read about the structure of the atom including its subatomic particles and John Dalton's theory of the atom. Students also read about the differences between atoms, molecules and compounds. They answer 30...

Neat! Show your physics class exactly how Ernest Rutherford fired alpha particles at a piece of gold foil and so determined that most of an atom is composed of empty space. Not just a slide show, but almost an animation, this...

An engaging activity enlightens young chemists in this lesson on atomic structure. They play musical chairs through a series of concentric circles that represent electon orbitals. A laundry basket in the middle holds the protons and...

In this biology worksheet, students complete 20 fill in the blank questions about eukaryotic cells. They identify the parts and functions of cell organelles.

In this biology worksheet, students read about the parts of both plant and animal cells and examine cell diagrams. They read about the function of cell parts before answering 11 online fill in the blank questions.

In this elements and compounds worksheet, students solve 27 clues in a crossword based on the atomic structure of elements and bonding of compounds.

Ninth graders explore the molecular structure of matter and how it can affect the physical characteristics of a specific material. They demonstrate that isotopes of an element have different masses. Students demonstrate that the rates of...

Scientists work every day to find solutions to genetic diseases. Scholars learn about the process of gene sequencing, mutations, and the results. They explore genetic diseases and therapies to intervene and help and, through case...

Five pages provide thorough coverage of three protozoans: euglena, amoebae, and paramecia. For each, junior biologists read factual text, label the organism, and write answers to several questions. This neatly organized assignment is...

Students discuss scientific advances brought about by the Mars Surveyor Space Program which impact on daily life, identify laboratory apparatus like microscopes, slides and coverslips, and use the microscopes to view cells and organisms.

Students explore the parts of a cell. They identify the structures of plant and animal cells. Students explain the functions of plant and animal cells. They compare and contrast animal cells to plant cells. Students create a model of the...

Students study the significance of the quantum model and how scientific theories adapt over time.  In this investigative lesson plan students describe the contributions that scientists have helped develop the atomic theory and...

Bring a set of pre-lab, lab, and post-lab lesson plans on volcanoes to your earth science unit. Sixth graders explore the three types of volcanoes found on Earth, plot the specific locations of these volcanoes on a map, and...

Here is an interesting science lesson/activity which has learners working in groups in order to simulate experiments done at the Jefferson Science Lab. In this one, groups use a pie tin, a Hula Hoops, a marble, and a magic marker to...

Students observe their own epithelial cells from the inside linings of their cheeks using DigiScope technology. They prepare a slide with both onion cells and epithelial cells and make an illustrated booklet for a PowerPoint presentation...

Students examine the roles of an animal cell's parts, how each part relates to one another and then demonstrate their knowledge by writing a story about the animal cell structure.

Students study the particles of which atoms are made. They define the electron, proton, and neutron and their attributes.

Students determine the approximate time a cell spends in each phase of mitosis by counting cells in each phase from a prepared slide. They use a few simple calculations to estimate how long cells spend in each cycle in the body.

In this nervous system worksheet, students are given seventeen clues about structures of the nervous system and they put their answers in a crossword puzzle.

An extremely thorough presentation walks new chemists through the basics of matter. There really isn't a unifying theme, however So many topics are covered: forces, elements, atomic structure, chemical properties, compounds, quarks,...

In this biology worksheet, students respond to 13 multiple choice questions related to cell structure and function. They identify which are microfilamets and which have a cell wall. Students also describe what chloroplasts are and their...

Students conduct an experiment comparing human cells to chicken cells. In this cells lesson plan, students conduct an experiment to see how nutrition moves through cells and how to better take care of their bodies.

Young scholars 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.
