Did you know the word energy comes from energeia, a Greek word? Introduce learners to the four types of potential energy, five types of kinetic energy, and energy transformation with a presentation about where we get our energy and...

What does the past have to do with today? Young scientists find that answer as they learn more about past chemists and their significant contributions to the field. Pupils use the Internet to research historical figures...

Electrons flow from negative to positive, but the general consensus is that current flows from positive to negative. Scholars explore current through construction of circuits in both series and parallel. The focus is on voltage,...

There is more about the Milky Way that scientists don't know than what they do know—that leaves a lot to discover! A thorough lesson presentation explores the components of the Milky Way Galaxy and their behaviors. 

Watson and Crick built the first model of DNA in the 1950s, and our understanding of DNA since then continues to grow exponentially. Scholars learn about protein synthesis by observing a presentation and completing a worksheet. Both walk...

Humans eat around 93,205 miles of DNA in an average meal. Scholars learn how to extract DNA from a strawberry using a presentation. It walks through each step and explains why the process works. Comprehension questions encourage...

Here is a good lesson which aptly describes how to do the classic "Oobleck" lab with your young scientists. Unfortunately, the "Oobleck Investigation Sheet" in the plan doesn't open. However, this is a very clear description about how to...

Without water there would be no life on this planet. Biology learners find out why by reading this handout. Create a worksheet of questions to answer after the reading. Follow it up with quick demonstrations or laboratory activities that...

Students discover the processes that occur during mitosis and what makes each phase different and distinct from the others as well as how each contribute to the overall process of mitosis by looking at onion root tips under a microscope.

Students determine what plasma is and why the sun is made up of plasma. They recognize situations where plasmas are found in nature and made by man. They discuss why the sun is a huge ball of plasma and if there are different levels of...

Here is a way for beginning chemists to review the skill of multiplying fractions! A segment of the periodic table of elements is presented at the top of the page, from which learners obtain the atomic number to use in six calcualtions....

Super detailed, this lesson will educate physical science learners about the flow of electrons. Begin by reviewing potential and kinetic energy with a moving pendulum, and then get them online to observe interactive websites about...

High schoolers plot particle sizes of common airborne materials on a log scale. They read an article on particle size and its relationship to the ability to pass through the lungs, into the bloodstream, and eventually into the cells...

Compare and contrast eukaryotes, prokaryotes, and viruses with a chart and a Venn diagram. Beginning microbiologists consider motility, reproductive ability, DNA content, and the presence of organelles. They write short answers to...

Future geneticists use base pairing rules to build DNA and RNA polypeptide strands, and then explain both transcription and translation. Although the chains themselves are a little blurry, there is plenty of room in them for learners to...

Students examine how traits are passed to offspring.  In this genetic reproduction lesson students develop a model of dna and learn about its structure, replication and function.

Introduce students to cells, and their many parts in this biology presentation. Students see that plant and animal cells have many of the same type of structures, but also have many differences as well. They will be challenged to state...

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...

Help your students understand cell division. Explore the topics of mitosis by examining the details of chromosomes at interphase, metaphase, anaphase, prophase, and telophase. Wonderful slides will keep your students' attention...

Wow! Colorful and simple, these 160 slides introduce the various forms of energy, along with a relevant image. Some of the images are animations, which help beginning physical scientists to visualize the flow of electrons or energy! This...

The first nine slides visit the history of our understanding of atoms. The next several outline the structure of atoms. Subatomic particles, electron configuration, and diagramming methods are introduced. This is a neatly organized...

This is a basic presentation that can be used to introduce your budding chemists to the structure of an atom. It gives step-by-step examples of a few atoms, showing their particles as well as their chemical formulas and the associated...

The ten slides in this presentation make a consice introduction to the halogen group of the periodic table of elements. The location of the group is displayed, and then the characteristics of the different halogen group members are...

Although there are vocabulary terms in this PowerPoint that use British spelling, the presentation is attractive and educational. The content flows from the general composition of blood, into the different types of blood cells and their...
