Using a tape measure, set up the catapult and the target 8 ft. apart. Make sure they are at about the same height. Insert the pin with the ring attached through the hole in the catapult base, lined up with a hole in the disk. This sets the launch angle (don't worry, you can always change this angle later).A hypothesis is a tentative, testable answer to a scientific question. Once a scientist has a scientific question she is interested in, the scientist reads up to find out what is already known on the topic. Then she uses that information to form a tentative answer to her scientific question. Sometimes people refer to the tentative answer as "an ...Before you even begin to design your survey questionnaire, you should develop a set of objectives for your research and list out the information that you are trying to capture.

In the mixing bowl, thoroughly mix 1/2 C water, 1/2 C glue, and a few drops of food coloring. Add 1/2 tsp baking soda and mix completely. Add 1 tbsp contact lens solution and stir vigorously until the mixture starts pulling away from the edges of the bowl. Seawater is usually somewhere between 33 and 37 ppt, which means that a 1 liter bottle of seawater would have 33–37 grams of salt inside! In this experiment you will learn a simple way to measure the amount of salt in a sample of water by using evaporation. This lesson is designed to guide your students through the steps of the scientific method (Figure 1) using a fun, hands-on project: paper rockets. You can read about the scientific method, or assign your students to read about it, in much more detail in this guide. Figure 1. Steps of the scientific method. Your students will build small rockets ...You will need to make and quickly measure only one popping boba ball at a time, because the balls can change over time. The tip of the syringe should be around 8–13 cm (3–5 inches) above the surface of the solution. Figure 5. Drop a single drop of the food solution into the calcium chloride solution, as shown here.

Chemically, agar is a polymer made up of subunits of the sugar galactose, and is a component of the cell walls of several species of red algae that are usually harvested in eastern Asia and California. Dissolved in boiling water and cooled, laboratory agar looks gelatinous. Although agar's chief use is as a culture medium for various ...Holding the spoon with the yogurt just above the sodium alginate solution's surface, carefully scoop the yogurt out (using a second spoon) so that it stays together as one whole blob in the solution. Clean out the measuring spoon and repeat steps 4.a.–4.e. two more times to make a total of three samples.Science Buddies mission is to inspire and educate students of all ages with hands-on STEM explorations that reflect their unique personal interests.

Black objects absorb all visible wavelengths about equally, and white objects reflect all visible wavelengths about equally. Light that is absorbed by an object is usually converted into heat energy. The goal of this project is to measure how much heat is produced by the absorption of light by different colors.Science Fair Project Idea.

A coil (or electromagnet) is created by coiling magnetic wire 10½ times neatly around a cylinder. Note 1.6 inches (4 cm) of wire is left free on each end to create the axles. Carefully slide the loops of magnet wire off the pencils or cylinder. Your coil might look circular or square, as shown in Figure 8, below. In this science fair project you will make a saturated solution of sugar and water in order to grow your own rock candy sugar crystals.
