Place each mixture into a separate jar or bottle (these recipes are scaled for 8 oz. For a group of 25 students, that would be 6-8 bottle sets. The more sets you have, the smaller the group students can work in. The number of bottle sets that you make is somewhat discretionary. Because these items are approximately the same size, using dry measurements (volume) is very roughly equivalent to measuring numbers of atoms. Note that these abundances are by volume, not weight. Prepare mixtures of these items according to the recipes below for the sources we are modeling. In this activity, each element is represented by a different food. 1 scoop of pink, purple, red, and yellow beads in roughly equal amounts (to represent 0.01% abundance of magnesium, silicon, iron, and sulfur together).1 scoop of orange beads (to represent 0.01% abundance of neon).1 scoop of green beads (to represent 0.01% abundance of nitrogen).2 scoops of black beads (to represent 0.03% abundance of carbon).3 scoops of dark blue beads (to represent 0.08% abundance of oxygen).5 scoops of light blue beads (to represent 9% abundance of helium).50 scoops of clear beads (to represent 90% abundance of hydrogen in universe).Using the same, or larger, size "measuring cup" for preparation as the students will each have during the activity. Mix the ingredients ahead of the planned activity in a large bowl. In this activity, each element is represented by a different color of bead. Clay (or Sculpey, for a more permanent model) of 5 or more different colors.Funnel for pouring ingredients into bottles.Periodic table handouts for each student.Example(s) of pure elements (sheet of aluminum, copper tubing, elemental density cubes, etc.).Napkins or paper plates to hold the pound cake (enough to serve the group, if allowed).Gloves or wet wipes for safe food handling. ![]() Explore the concept of composition in the context of astronomical objects.Gain knowledge of the processes in the interior of a star.Learn how heavier elements form from fusion.Determine the most abundant elements in the Universe.Familiarize the students with a periodic table and common elements.Audience:Ī group of 20-25 students (grade range 5th-7th) Objectives: Finally, students are introduced to the idea that hydrogen fusion creates heavier elements inside a star. They compare their findings of the Universe's overall composition with the composition of various different objects in the Universe that are represented by mixtures of rice, beans and other dried goods in jars. As an exercise in statistics, the students participate in a counting experiment in which they sample a 'Universe bead mix' (where each bead color represents a different element present in the Universe) to estimate the overall composition of the Universe. The group discusses how all material in the Universe is composed of elements and that the atom is the smallest particle that still has the physical and chemical properties of any given element. Students are introduced to the periodic table and the concept of atomic elements.
