Students will create mixtures using objects they find in the garden. Also, they need to be able to write a conclusion based on observations.
In 4th grade, students will compare and contrast a variety of mixtures including solutions that they can make indoors. In 5th grade students will create mixtures and note the physical properties of each of the ingredients within.
STUDENT ACTIVITY - 4th - TXThis is a distance-learning lesson students can complete at home. The student will compare and contrast a variety of mixtures, including solutions, that they can make outdoors. This activity was created by Out Teach (out-teach.org), a nonprofit providing outdoor experiential learning to transform Science education for students in under-served communities.
Students conduct an experiment to determine how varying the composition of a construction material affects its strength. They make several adobe bricks with differing percentages of sand, soil, fibrous material and water. They test the bricks for strength by dropping them onto a concrete surface from progressively greater heights. Students graph the experiment results and use what they learn to design their own special mix that maximizes the bricks' strength. During the course of the experiment, students learn about variables (independent, dependent, control) and the steps of the engineering design process.
In this lesson the students will create mixtures and note the physical properties of each of the ingredients within.
Students will recognize that mixtures are made when two or more materials from the garden are mixed together and the physical properties do not change.
