This lab incorporates observational skills to solve the problem of finding the best rock to build tables for a museum picnic area. Students are called on to observe the properties of the rock samples and then required to apply what they learn to choose the best rock for the job.
This activity directs students to set up a two step classification scheme based on the physical traits of color and shape.
This activity has students sort garbage, graph their results and propose ways of reducing waste.
This lesson plan requires students to make an inference (hypothesis) about two animals based on the tracks they leave behind. Students are asked to write a story explaining their inference.
A lesson plan for guiding students through a simple research experiment focused on transfer of energy is described for teacher administration and student explanation. Also includes a detailed rubric for evaluating student work.
Students use a 10 step dichotomous key to identify three mythical animals of their choice. The pictures of the animals and the key are both provided.
Students test their observation skills as they make predictions about the objects that are in three different boxes.
Straightforward introduction to electrical circuits using minimal materials and time. Students learn about the basics of electrical circuits by experimenting with "mystery cards" -- index cards with hidden aluminum foil used to conduct small amounts of electricity produced by a battery.
A unique approach to determining size and weight of an object through water displacement: students are presented with a scenario along with a variety of balls made of different materials and pitchers of water. Working in small groups, they explore the properties of the materials, then interpret their observations in their own words during the individual portion of the lesson.
Students are given some guidelines to develop experiments to see how slugs or earthworms repsond to stimuli such as vinegar and light. This activity is designed to last 4 class periods.
