If you're finishing up a unit on cells, here's a great project to get kids collaborating and recalling what they've learned in a fun and tangible way. Small groups create plant or animal cells out of materials they have at home. They use...

I don't trust atoms because they make up everything. Budding scientists learn about famous scientists connected to atomic models, chemical, ionic, and hydrogen bonds. The presentation also presents how to count atoms...

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...

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...

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

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...

Young scholars 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.

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...

So often, genetics worksheets focus on alleles and heredity. Here is one that focuses on the steps of the gene expression process. After reading a textbook chapter or listening to your lecture, AP biology buffs write short answers to...

The many slides and images in this PowerPoint are clear and relevant to the detailed content covering the details of DNA structure, replication, cell differentiation, and mutation on an advanced level. The slideshow summarizes all of the...

Even though the presentation is connected to a particular textbook, it could be used in any lower elementary classroom to review plants. There are diagrams and colorful graphics that make it attractive and engaging.

Three steps are needed to extract DNA from learners' inner cheek cells. The procedure and reasons for each step are explained. As enzymes work on the cells, a series of questions are answered regarding the structure of the DNA molecule....

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...

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,...

Multiple representations of the varying theories of atomic structure. With these pictures and some background of the theories and scientific figures surrounding them, your class will develop a better understanding of scientific history...

Organelles, cellular respiration, ATP, and DNA. The passage attached to this life science reading comprehension worksheet is all about cells. After reading about diffusion and osmosis, kids answer a series of questions based on the text.

In a simple activity, physical scientists model nuclear fission using a droplet of oil. This can be used alone in a unit on different types of energy, or as part of the energy conservation unit produced by the Texas State Energy...

Get down to basics with these worksheets on the structure of atoms. Challenging young chemists to identify information from the periodic table and create Bohr diagrams and Lewis dot structures for different elements, this...

Introduce third graders to energy waves with a hands-on geology activity, in which they answer questions and compare seismograms in the San Francisco Bay area. After a demonstration that shows how bigger waves indicate a...

Fifth graders explore volcanoes and the rocks they produce using the Internet. The lab portion of the lesson prompts young scientists to compare and describe igneous rocks. Next, they critique a pair or more of...

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...

Young seismologists learn more about plate tectonics with a set of pre-lab, lab, and post-lab lessons plans on earthquakes. After exploring how waves travel through various materials, sixth graders record their observations and...

Sixteen ounces of honey requires more than 1,000 bees traveling over 100,000 miles and visiting 4.5 million flowers. The presentation includes sexual reproduction in plants, the parts and functions of a flower,...

The difference between atomic mass and atomic number can be confusing for some young chemists. Help your class better understand the concepts by allowing them to sketch an atom on paper and then discuss their experience. Upon completion...
