In this chemistry worksheet, students identify and locate various vocabulary terms related to metals found in the periodic table. There are 54 chemistry terms located in the word search.

In this biology worksheet, students locate and identify various vocabulary terms relating to cells and microscopes listed on the right. There are 26 biology terms located in the word search.

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 create atoms with clay by using different colors to represent the protons, neutrons and nucleus. In this creative lesson students use clay to learn about atoms and see how they apply to the periodic table.

Initially, general details about cells and single cell organisms are provided. Next, the concentration becomes cellular processes such as respiration, osmosis, diffusion, fission and mitosis.  This is an attractive PowerPoint which...

A huge slide show provides a review of almost every topic there is to cover in basic chemistry! Your young scientists will be interested to see each illustration and example given. The appearance of the 120 slides varies greatly, most...

Eighth graders discuss and write about what led up to the discovery of the atom. Students label proton, nucleus, electron, and neutron in their notes. Students take notes on electron shells and how different atoms have different...

For this microviewer worksheet, students observe several types of cells. Students draw each type of cell and label the important parts. Students also answer questions relatable to the cell and the purpose for study.

Life science learners investigate live cells. They examine wet mount slides of cyanobacteria and Elodea plants. They peer into the dynamic microscopic world of protists. Afterward, they construct a model of a cell, including rudimentary...

In this building your own cell worksheet, students identify cell vocabulary and facts, and create posters of a labeled plant cell and an animal cell. In this fill-n-the-blank and posters worksheet, students provide twenty-three answers.

In this biology worksheet, students watch a series of videos and complete 10 short answer questions right after. They explain how ART drugs interrupt the life cycle of HIV.

Students encounter concept maps for reviewing evolution. Concept maps provides an alternative method of interacting with the information and a forum for asking questions about vocabulary, concepts and interrelationships. A quiz is...

Students investigate the importance of sexual reproduction in evolution. In this sexual reproduction lesson plan, students simulate species with two traits: eye and skin color. They determine what characteristics are beneficial for the...

In this colliding asteroids instructional activity, students are given the equation to determine the collision time for asteroids. Students use this equation to solve 4 problems including finding the area of a cross-section through the...

Starting with a recap of atomic structure, these slides continue by comparing different isotopes of uranium and explaining which are stable and which have a decay period and emit alpha or beta particles. Gamma decay is just mentioned on...

For years, scientists believed tRNA was junk left over from larger RNA. Three scientists used different approaches to prove tRNA actually exists as the connection between DNA and protein. Learn about their experiments, their lives, and...

In this chemistry worksheet, students describe an atom, its parts, the charges of these parts, and atoms life functions. Then they explain what the octet rule states for the placements of electrons around the nucleus of an atom. Students...

Atomic theory, experiments that contributed to our knowledge of matter, atomic structure, isotopes, and ions are covered in these 33 slides. Quality diagrams and labeled charts will help activate understanding. The presentation concludes...

The billions of cells that make up all living things are the focus of this resource. Understanding the differences between the cells that make up plants and animals is an important distinction; it is covered here quite-well. Some...

A great way to learn about molecular structures is to make a model. Gumdrops and toothpicks are used to construct crystal models. The models are based on theories of crystal shapes that occur because of positive and or negatively charged...

Using a copy of the periodic table, chemistry test takers fill in a chart with element name, chemical symbol, atomic number, atomic mass, and numbers of subatomic particles. They define subatomic particles, draw atom models, explain...

Here is an interactive book instructional activity through which learners explore the facts and stories about comets. The plan is comprehensive, providing background information, standards met, vocabulary, assessment ideas, and more....

Students experience a "hands-on" activity to get visual evidence of the physical nature of DNA and the process of DNA purification. They explore one method of chromosomal DNA isolation and DNA extraction.

A basic presentation to introduce some of the terminology regarding atomic weight, atomic structure, and atomic number awaits your students. An example of the calculations finding average atomic mass for carbon is given, and a way of...
