It's all about freshwater in this water interactive! Users navigate through freshwater habitats such as lakes, rivers, and wetlands, taking note of the animals that live there. They also look at a desert habitat for comparison....

Dirt is worthless, isn't it? Find out the true value of dirt, and by dirt I mean soil. The class explores what makes soil, the types of soil, and what happens when soil becomes void of its nutrients. There are several great activities,...

How large can a population become? The fifth installment of a nine-part unit teaches young ecologists about limiting factors that determine the carrying capacity of species in the Sonoran Desert. Here is a PowerPoint to help present this...

This review sheet will be very useful to test your pupils' understanding of battery structure and redox reactions.  The questions ask for equations to be balanced and for the traditional equipment setups to be drawn and labeled....

Several slides compare different temperature scales. Thermal expansion, heat transfer, and Maxwell speed distribution are also explored. The last two slides seem unrelated to the topic of heat, but are easily left out of this otherwise...

How can engineers help their communities? Three challenges in the first unit explore why STEM is important to communities and how neighborhoods are engineered to experience those benefits. The second unit prompts groups to plan an...

The house lights dim, the curtain parts, lights slowly come up, revealing the stage. Before the actors appear, before a word is spoken, the audience is drawn in by the lighting, by the colors, by lines of the set, by the props, and...

In this bridge design worksheet, students answer 5 general questions about bridges. Students follow the directions to construct 4 types of bridges with paper and test them for strength.

Students study types, strength and construction of a variety of bridges. They build a model bridge and test the amount of weight it support.

Students analyze bridge designs and functions.  In this reinforced bridge lesson students brainstorm bridge ideas, divide into teams and give an oral presentation to the class to show them their bridge design. 

In this engineering science quiz worksheet, students respond to 10 short answer questions regarding civil, mechanical, electrical, chemical, and aerospace engineering.

Bycatch is the unwanted and discarded marine life caught during commercial fishing. Young marine scientists review bycatch litigation and analyze graphs of bycatch data and answer questions about it. This raises awareness while...

Hold a discussion in your class about the increase in mercury being found in fish that are caught commercially as food for humans. Given a worksheet, learners then calculate how much fish a person can safely eat each month to remain...

The topic is fascinating, but there is not much for learners to do here. Food borne illness has always been a problem for humans to face, and here, data from the Center for Disease Control is analyzed. Learners look at the number of...

Pretend you are exploring a newly discovered species of fish in the Galapagos. Your budding marine biologists access FishBase Database's list of marine/brackish fishes and choose one to research. The link through this website does not...

The first thing to know about this lesson is that the commercial fisheries data for the activity no longer seems to be available. That being said, there are fascinating links to other websites, some about the comparative odds of being...

After listening to your lecture on climate change, young scientists access NOAA's database listing Mauna Loa's carbon dioxide data. They graph the monthly means and then compare their graphs to NOAA's. This is a concise plan that could...

The theory that adding iron to ocean water may increase phytoplankton ability to remove carbon dioxide from the atmosphere is examined. The Monterey Bay Aquarium Research Institute is monitoring conditions off the California coast to...

Fourth graders complete analysis experiments for decomposers and their adaptable traits. In this decomposers lesson, 4th graders test worm behavior to light, sound, warmth, touch, and moisture. Students work in groups to analyze the...
