Take young biologists back to the beginning of life on Earth with this presentation on bacteria. Examining the different classifications of bacteria, this presentation introduces young scientists to the concepts of autotrophs and...

Students grow bacteria cultures on agar in petri dishes and do a plate count. They participate in a yogurt making lab to see how bacteria produce lactic acid. They prepare a recipe and identify fungi, fermentation and the role of...

Young scientists or chefs culture yeast to produce yogurt. The materials and a general description of how make yogurt are provided, but there is very little detail otherwise. You could use this as an activity when your biology class is...

Scholars use a lab simulation to test contaminated yogurt for bacteria by gram staining. They learn proper lab procedures for handling bacteria and for sterilizing equipment, and then walk through the process on their own to try gram...

Students make yogurt from powdered milk. In this yogurt experiment lesson plan, students combine powdered milk, warm water and plain yogurt. They mix up the ingredients and put it in an insulated cooler for 6-8 hours. 

Sixth graders produce yogurt in the classroom as an example of the use of microbes in food production, and record observations in science journals.

Students discover the role microorganisms play in our lives. In this decomposition lesson, students examine decaying foods and plants in order to analyze the different bacteria that grows. Students discuss the good and bad of...

Sixth graders conduct a variety of experiments that enable them to investigate bacteria. They use microscopes, prepared slides, video, moldy bread and pond water to observe types of bacteria and how bacteria interacts with the...

Some microbes are beneficial for humans. This resource asks learners to identify beverages that contain healthy microbes. There are six beverages shown, and pupils must place a check mark next to the ones they think contain healthy...

Seventh graders study microorganisms in their environments by experimenting with milk products. In this microbes lesson, 7th graders read background information about microorganisms in yogurt and soured milk. Students then follow a...

In this prokaryote worksheet, learners answer ten questions about prokaryote cells and they color a diagram of a simple bacteria cell and its structures.

Students discover that the answers to some of society's waste and clean-up problems may be no further than the soil beneath their feet. They perform a Gram stain on the colonies to determine some of their characteristics.

Fourth graders complete a variety of experiments to meet science goals.  In this life sciences instructional activity, 4th graders make yogurt, discover the attraction of opposite charges in electricity, learn the effects of...

Fifth graders make cheese using two different methods. In this cheese making instructional activity, 5th graders make rennet cultured cheese following the step by step directions. They also make cheese using a genetically engineered...

Practice nutritional cooking with a collection of fun meal preparation lessons. Each lesson includes a focus, objective, collaborative activity, and recipe to culminate what young cooks have learned about healthy eating.

The question posed for the class to consider; What would decay and what would not? They read the short passage on decomposition and microbes, then mark the items that would decay after a two-week period. A scientific investigation idea...

Students explore the process of making butter. In this agriculture instructional activity, students discuss how butter is made today and how it was made in the past. Students make their own butter using baby food jars and some "elbow...

In this prokaryote coloring activity worksheet, 7th graders read an informative passage about prokaryotes. Students answer questions about the passage and color the picture.

Young scholars conduct an experiment where they will change a liquid dairy product into a solid. They review the definitions of liquids and solids. Students are given an example of each. They are divided into groups of four, each group...

Students plan a picnic menu using the food safety rules. They pack a cooler with different types of cold packs and also pack a basket with food that does not have to be kept cold.

Sixth graders explore biology by viewing video clips in class. In this microorganism identification instructional activity, 6th graders identify the types of organisms that can feed small animals such as algae and protozoans. Students...

Learners examine how not all microorganisms are bad and that some can actually be beneficial.  In this yeast lesson students complete an experiment with yeast and answer questions.

Find out in this experiment how good bacteria can turn milk into a treat by investigating the optimal starter cultures for making yogurt from whole milk.

[Free Registration/Login may be required to access all resource tools.] Yogurt is a good source of calcium. Yogurt also contains active cultures of "good" bacteria. Foods that contain these beneficial bacteria are sometimes called...
