Life science laureates choose a plant or animal cell to construct a model of as an at-home project. This handout provides guidelines, suggested materials, and a grading rubric for their reference. A full-page letter to parents is also...

There are different types of radioactive decay, and alpha decay is when there are too many protons in a nucleus. Here is a simulation that shows alpha particles being emitted from a polonium nucleus. Learners see how radioactive decay...

How much energy is required to break apart an atomic nucleus and does it vary based on the type of atom? Scholars virtually experiment with a linear accelerator in order to answer these questions. They alter the voltage, length of the...

Young scholars examine the functions of mRNA, rRNA and tRNA. They explain the steps in the protein synthesis process. They practice using new vocabulary as well.

Students examine their cheek cells with a compound microscope. They identify different parts of the cell. They compare and contrast animal and plant cells with the microscope as well.

In this making atoms science worksheet, students read about the atomic number of protons, finding the number of neurons, and how electrons function before they complete the atom board graphic organizer and respond to 4 short answer...

In this human cells worksheet, 7th graders complete a science experiment using human cheek cells. Students sketch the cells at high and lower power and label the cell nucleus, cytoplasm, and cell membrane.

In this atom activity, students review the structure of an atom. Students also explore radioactive elements and quarks. This activity has 10 fill in the blank, 6 true or false, 1 short answer, and 3 multiple choice questions.

Students investigate what is wrong with the Rutherford atomic model. In this chemistry instructional activity, students answer questions about the atomic model after watching a video. They draw conclusions from the video and discuss how...

Students research the developments of animal and human cloning. They report their findings to the class. They write journal entries as well.

Students explore neurological disorders. They examine the presence and absence of discernible genes. Students describe neruological diseases and draw faces of affected persons. They play a human neurology disorders learning game.

In this biology worksheet, students identify and describe the three types of RNA, messenger, transfer, and ribosomal RNA. Then they write the key features of molecules of RNA for each form.

Students create paper comet models. They discuss facts about comets and build a model to determine the way the sun affects a comet. They create a comet and label the head and tail portions. They discuss their comet model and share it...

In this euglena worksheet, students read information about these unicellular organisms. Students then color in the different structures of the euglena on a diagram. Students complete 10 short answer questions.

In this stars worksheet, students read about the different stages in the life cycle of a star. Then students complete 3 short answer questions.

For this comet worksheet, learners will read information about the Comet Halley that has been collected by recent space probes. Students will use this information to complete 7 short answer questions.

In this atomic structure worksheet, high schoolers answer eleven short answer questions about the structure of atoms including the number of protons, neutrons and electrons. Students indicate the differences in isotopes of atoms and what...

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

In this elements worksheet, students review the Bohr model and define negative and positive subatomic particles. Students compare molecules and compounds. This worksheet has 11 short answer questions and 4 problems to solve.

Seventh graders describe the basic structure of the DNA molecule. They identify what an inherited trait is and how it can be determined by one or more genes. Finally, 7th graders identify that plant and animal cells contain several...

Physics apprentices analyze the impact of NASA's Impactor as it collided with the comet Tempel 1 in July of 2005. They calculate the mass and speed of the comet, along with the distance it might drift off of its orbit over time. This...

Here is a fantastic, informative, interactive presentation on plant and animal cells. The PowerPoint is produced by an elementary school teacher who has a doctorate in science, and it shows! This would be a splendid presentation to use...

The creator of this collection of chemistry slides is clever! Electron configuration is explained as, click-by-click, orbitals are displayed and then each is subsequently filled with the proper amount of electrons. After the progression,...

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...
