Knowing how to mix concrete is a big part of having a construction job. Here vocational learners will go through the types, economy, and uses for concrete. Each slide is rich in text but organized in an easy-to-read style. Images and...

Don't let your eyes play tricks on you ... use scale to keep your eyes in check! Young scholars observe images without scale and try to identify the structure. Then, they look at the same image with a scale bar and assess whether their...

Building off young chemists' knowledge of the states of matter, kinetic molecular theory is the focus of the unit. Eight days of lessons including multiple demonstrations, one lab experiment, directed instruction, and worksheets,...

Mother Nature's Gravel Company is open for business! The unit includes four lessons covering weathering and erosion. Experiments are simple to complete and young geologists compare notes to see who makes the biggest ice...

Second graders become familiar with the parts of the microscope and how it works.  In this microscope lesson, 2nd graders experiment with different light and settings.  Students answer questions based on their experiment.

Sixth graders examine mold with a microscope. In this micro-organisms lesson, 6th graders use teacher-prepared mold samples to prepare a wet-mount slide and examine the mold under a microscope then draw and label what they see.

Two sequential parts to this lesson introduce your class to the electromagnetic spectrum, the ability to absorb radiant energy, and the pigments in leaves that are responsible for collecting sunlight to be used in the photosynthetic...

In this forensic science worksheet, high schoolers identify the different parts of the hair. They complete 18 short answer questions on how hair evidence is used in forensics.

Let's get a closer look at DNA and other molecular structures. The first lesson plan in the series of four introduces a variety of imagining techniques that engineers and scientists use to visualize molecular structures. The resource...

Students examine the structure of Velcro and its function then relate it to seeds and seed stock.  In this experimental lesson students test seed activity and what its function is for the plant, examine seeds under a microscope, and...

Introduce your class to one of the ways that technology is benefiting humanity. The Global Precipitation Measurement Mission involves the data collected by nine satellites from different countries with a united focus on studying world...

We know that the type of soil varies by location, but does the seafloor sediment also vary, or is it all the same? Scholars compare photos of the seafloor from two different locations: the Savannah Scarp and the Charleston Bump. Through...

Hands on science is the way to go! Learners conduct a lab experiment to help them explain how plants make food through photosynthesis. They test for the presence of starch in leaves using iodine solution and identify the basic things...

Nothing flows like J-E-L-L-O! In the final portion of a four-part series, pupils create scale models of microfluidic devices out of gelatin and bendable straws. They use their devices to test various flow rates in the delivery of...

Future chemists practice laboratory techniques by creating a monochloramine solution. The objectives are to use of dilution, 9concentration, and measurement skills and to prepare a solution that will be used in a water treatment...

For this cells worksheet, students answer questions about the first person to see a cell as well as the evolution of microscopes. They define the parts of a cell and tell the differences between Prokaryotes and Eukaryotes. There are 20...

Students investigate living creatures that inhabit a pond and explore how various organisms satisfy their needs within their environments. In this life in a drop of pond water lesson, students examine microorganisms under...

Learners explain the concepts of what DNA is and where it is located in a cell, identify the two types of molecules that make up the rungs of a DNA molecule and identify the two types of Purine and Pyrimidine molecules

Students will explore cells to understand that all living things are composed of cells. In this science lesson, students use the scientific process and work in cooperative groups to gain a better...

Students compare cell structure to the structure of a city. For this cell structure lesson, students investigate differences and similarities between cell structure and city structure. Students create a 3-dimensional, edible model of a...

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.

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...

Use salmon eggs as a cell model for demonstrating the movement of water over concentration gradients. Junior scientists examine the same process microscopically with an onion cell. They use a thistle tube and a semipermeable membrane to...

Help your class understand the magnitude of the distance between Earth and Mars with an activity that asks small groups to use balloons to create scale models of the Earth, Moon, and Mars. Class members figure out the distances...
