Standard 2/Elementary/Benchmark 4
Benchmark Question: How do living things obtain and use
Focus Question: How do the life requirements for a
plant and animal compare?
Students will plant a seed
in soil (for example, grass, corn, bean, Wisconsin Fast Plant). In a
journal, students will record growth and life requirements (See Key
Concepts) StudentsŐ data should contain what the plant needs to survive
over a short period of time. The class will create a chart to organize and
record data. This chart should include life requirements and energy
sources. Students will then observe either an animal (e.g., mealworms) in
the environment, classroom, or home and record observations for the same
amount of time.
Students will work in small
groups to complete a Venn diagram comparing their plant and animal. Groups
will report their results to the class. The class will generalize that
animals require food from another source while plants use the sunŐs energy
to make their own food. The class should conclude that while habitats and
food sources may differ, the need for air, food, water, minerals, sunlight,
and space are similar.
