Science Safety: Plants in the Classroom<br>
02
Key Question What precautions should I take when using plants in the classroom?<br>
03
Purpose of Plants Plants serve both decorative and learning purposes
Useful for observation, measurement, classification, and experimentation<br>
04
Classroom Plants Ensure that students never eat any part of an unknown plant
Including seeds and berries
This includes plants on the school grounds and plants seen during events such as field trips<br>
05
Classroom Plants Help students understand the difference between edible and non-edible plants, vegetables, and fruits<br>
06
Plants to Avoid Plants containing toxins should not be present in classrooms
Plants that contain toxins when eaten
Examples include azaleas, lantana, delphinium, iris, pokeweed, tansy, hemlock, foxglove, jimsonweed, dieffenbachia, philodendron, caladium, buckeye, and belladonna<br>
07
Plants to Avoid Plants that have toxic sap
Examples include oleander, poinsettia, and trumpet vine
Plants that are toxic to touch due to oils
Examples include poison ivy, poison oak, poison sumac<br>
08
Plants to Avoid Plants that have edible parts, but also have inedible, toxic parts
Examples include potato leaves and sprouts as well as rhubarb leaves
Teach students to avoid touching all types of mushrooms found outdoors<br>
09
Plant Poisoning and Allergies Symptoms of plant poisoning may include headache, nausea, dizziness, sweating, tightness in the chest, vomiting, skin itching or dermatitis
Know who on your campus can recognize toxic or poisonous plants which are commonly found on school grounds (ex. Poison Ivy)<br>
10
Fertilizers Must be labeled and locked in cabinets
MSDS sheets must be posted
Goggles and gloves should be worn when handling fertilizers<br>
11
Experimenting with Plants Seed Sprouting
Seeds from a grocery store (those for eating) are safer for sprouting activities
Seeds for field planting often have protective, chemical coating<br>
12
Experimenting with Plants Aquatic Plants
Use caution with aquatic plants especially from ponds or marshes
Avoid direct contact with mud and pond water<br>
13
Experimenting with Plants Soil Studies
Generally safer to study potting soil
Soil dug up from school grounds or home yards often contains mold and fungi
Use proper tools and safety equipment<br>
14
Sign School Safety Roster Be sure to understand each of the previous items
Sign the Roster attesting your understanding<br>
