Students answer questions about how microorganisms can affect our food supply and how they can be controlled. The first set of inquiry activities are directed by the teacher. Subsequent activities are based on students generating their...

Students describe what each detection method uses and rank the wavelengths of each if appropriate. They answer questions about absorption, importance of materials and explain differences. Students make sure they describe diagnostic uses...

Fourth graders discuss density.  In this floating golf ball lesson students complete a lab activity on density while working in groups. 

Young scholars examine why diffusion and osmosis happen in an egg cell.  In this diffusion lesson plan students demonstrate a semi permeable membrane.

Is buying in bulk always better? In this real-world scenario, learners must decide which weed killer is the best bargain. Students work with units and percentages to calculate cost per fluid ounce.

A fill-in-the-blank worksheet regarding transport, this handout would make a great study guide or quick homework assignment to help learners ensure they know the key vocabulary for this topic. There is no answer key, but these are...

Even though they were written for upper-level high schoolers or college pupils, the labs herein are possible to use even in middle school. In the activity, kids observe osmosis in both potatoes and elodea plants, then record and graph...

Mixing substances together causes their properties to change. This resource illustrates that concept for fifth graders by having them consider four questions that have to do with buoyancy and boiling point. Learners begin to understand...

If you have elodea and snails in your classroom aquarium, or if you have access to a pond with these organisms, your young biologists can set up a controlled experiment to determine how certain ecosystems respond in light and dark...

Students improve their skills and comprehend the particular application for which serial dilutions are a tool. Serial dilutions are often used in microbiology, biotechnology, and in chemistry classes, to name just a few.

For this halogen chemistry learning exercise, students complete a practical to gain experience observing inorganic halogens and their salts. They observe changes in each chemical reaction and write the chemical equation for each experiment.

In this variables worksheet, students are given seven experiments that they read and identify the independent variable, dependent variable, control group and standardizing variable.

In this salts and buffers worksheet, students answer five questions about the acids and bases that form salts as well as the equations for a buffer system.

In this equilibrium and water chemistry worksheet, students solve twenty problems related to acids and bases, equilibrium and water.

Want my name and number? It's 6.0221415 times 10 to the 23rd, and my name is Avogadro. Providing nine different activities, experiments, and labs, this lesson keeps Avogadro relevant to your class all year long. 

In this bias in graphs instructional activity, learners examine graphs and explain the data. They determine why the graph is or is not biased. This four-page instructional activity contains approximately 6 problems. Explanations and...
