Free printable worksheets using a ruler3/19/2024 Part 2 (students set up their mold terrariums) takes 15 to 20 minutes. Part 1 (students brainstorm ideas for their mold terrarium) takes 10 to 15 minutes. You may want to divide this activity into two sessions. Homeschool students can work on their own. We suggest students work in groups of four. Opening the bag would release mold spores, which can exacerbate asthma and cause respiratory illness. When your observation period is over, you will throw the entire experiment away. Students will observe mold through the clear plastic, but will not open the bags. The space you have available may limit how many terrariums you make.Įach mold terrarium will be sealed in a Ziploc bag that is then sealed with duct tape. In addition to the supplies listed above, you will need a well-ventilated area to store your mold terrariums. You will need access to water for this activity. In addition to the supplies used to make the Balance Scale and Balloon Corral, each pair of students will need the following materials. Directions on how to make a balloon corral are found on the Teacher Instructions printout. To make one, you need a coat hanger, a heavy book, and a few more jumbo paper clips. We use a balloon corral to keep our balloons from roaming. Having balloons loose in the classroom can distract students. Follow the directions on the Teacher Instructions to make your balance scale. You also need a yardstick, 5 medium binder clips, 2 jumbo paper clips, a wooden ruler, a pencil, and a heavy book. You need a cleared off desk or table to set up your balance scale. Once you have the circumference, cut that length of string for each pair of students. Find the circumference by multiplying the diameter by pi (3.14) or by checking the table below. The size is the diameter of the inflated balloon. To figure out that length, check your balloon package for the size of your balloons. In order to do this, students need a piece of string (or ribbon) that’s cut to the length of the balloon’s circumference. This activity will only work if the balloons are fully inflated - which to most people looks like they are about to pop! After inflating a balloon, students will measure the circumference of their balloon to make sure it is fully inflated. You and your students can run the experiment multiple times. If that gives you more than 8 balloons, that’s fine. The supplies calculated above will provide one balloon per pair of students. Homeschool students can work on their own, but you will need a minimum of eight balloons for this activity to work. We suggest students work in pairs for the first part of the activity.
