Nutrient Deficiency in Plants— Hydroponics Laboratory Kit
Students compare hydroponically grown plants with plants grown in soil. In their exper- imentation, they will also study the effects of missing macro- and micro-nutrients. Pre-mixed nutrient solutions, seeds and growth chamber materials make preparation time minimal. Includes detailed instructions, hydroponics background and anticipated results.

Spontaneous Generation— Demonstration Kit
Prior to Louis Pasteur, it was believed that living microbes could arise from nonliving matter by spontaneous generation. Pasteur’s classic S-tube flasks proved key in dispelling this belief, and now your students can
easily duplicate this classic experiment that exposes media-filled flasks with different openings and treatments to air containing microbes. Only flasks where microbes come in direct contact with the media will become contaminated.

Yeast on the Job— Student Laboratory Kit
Biologists recognize four fundamental processes of cells—homeostasis, cellular respiration, enzyme-controlled reactions and reproduction—basic concepts critical for
an understanding of a modern biochemical model of cellular life. Solidify these abstract concepts for students by experimenting with yeast cells. Viewing the cells, collecting data and designing experiments all contribute to students’ understanding of these concepts.

“Constructing” Mitosis the 5E Way— Student Laboratory Kit
Asexual reproduction, cell division and fission all generally refer to mitosis. Students gain written, verbal and visual understanding of the mitotic process and events in each phase as they draw simple cell diagrams and then identify onion root-tip cells undergoing Interphase or a specific phase of mitosis under a microscope.

Trees contain some of nature’s most accurate records. Students unlock these historical mysteries and uncover environmental trends of the past by studying actual tree round samples. Differences between hardwood and softwood trees, good years of tree growth versus poor years and ages of trees will be determined. Includes five sets of three different types of tree round samples, detailed student and teacher notes and all required materials.
