Earth Science Lab Safety

Materials:

• A picture of an unsafe lab
• markers, colored pencils, or paints
• blank white paper (1 for each student)

Objective:

• Students will demonstrate a good understanding of safety procedures by correctly identifying the dangers of heat, chemicals,electricity, lab equipment, and biological organisms.
• Students will identify dangerous situations while looking at a picture or video of a common lab situation.

Standards: (B2) A student should design and conduct scientific investigations using appropriate instruments; (B6) A student should employ strict adherence to safety procedures in conducting scientific investigations.

Anticipatory Set: Students will be shown a photo with several unsafe lab practices. Students will identify as many unsafe items as they can at least 10. Click here for picture

Teacher Input: The teacher will go through the one page list of safety issues to follow in a biology lab. http://yksd.com/distanceedcourses/YKSDbiology/labs/labsafety.html

Teacher Modeling: The teacher will then use several items in the classroom both safely and unsafely. The students will identify which way is safe and which is not.

Check for Understanding: Students will demonstrate understanding while the teacher is modeling safety procedures.

Guided Practice: Students will take turns explaining things around the school that are safe and unsafe. Students will also recall incidents in the school were someone was hurt because rules or safety procedures were not followed. Students will redevelop the list introduced to them at the beginning of the lesson and add items that were left off.

Closure: Students will take the quiz on Earth Science lab safety This will be the students first grade. They may take the quiz as many times as they want.

(15 minutes before or after the lesson) Independent Practice: Students will use markers, colored pencils, pencils, or paints to sketch a picture of an unsafe biology lab. The picture should have at least five things that are unsafe. Remind the students that the pictures will be hung up and/or passed around. (Best pictures will be posted on the web)

Duration:

45 minutes + 10-15 for picture (longer for homework).
