MATH IN SCIENCE Scientists use MATH each and every day when they are working in SCIENCE! Let’s look at some examples where we use science and math together in your 2nd grade studies. Charts and Graphs Scientists often use graphs to show clearly the results of their experiments. Scientists use bar graphs to help show their results. A bar graph uses bars and numbers to show information. Scientists also use many different charts to easily show the information they have learned and discovered when they do experiments. A column chart has facts in columns or sections which makes the information easy to read. © Copyright NewPath Learning. All Rights Reserved.

Studying Plants Scientists often use graphs when recording the results of the experiments. You use graphs in MATH too! Look at this bar graph. Which plant grew taller plant A or plant B? Plant B grew taller than plant A. Studying Animals Scientists use graphs when studying animals too. Look at this column graph. Which animal lives the longest? You can see on the column chart that the blue whale lives the longest. Let’s check what we have learned so far: Why would a scientist make a graph? © Copyright NewPath Learning. All Rights Reserved.

Studying Water Habitats Scientists use thermometers and graphs to chart the temperature outside and of water. Look at this chart. What was the temperature of the ocean at 8:00 a.m.? The temperature of the ocean was 10°C at 8:00 a.m. Studying How Living Things Grow and Change Scientists use numbers to study how long an animal lives. For example, they use numbers and a calendar to figure out that a Monarch butterfly lives for about 2-6 weeks. Studying How Plants and Animals Live Together Scientists often add and subtract when they are observing things and conducting experiments. For example: Scientists may add how many centimeters a plant grows during the week, how many birds come to a bird feeder, or how many snakes live in a certain habitat. © Copyright NewPath Learning.

Studying Energy Needs Scientists use math and graphs to sort out their findings. For example: How long did it take to move box A without using the pulley? Box Time it took to move using the pulley Time it took to move WITHOUT using the pulley Box A 10 minutes 25 minutes Box B 8 minutes 18 minutes The chart says it took 25 minutes to move Box A without a pulley. Studying Earth’s Weather Scientists may use tools to measure things during experiments too. For example: Scientists may use a rain gauge to measure how many centimeters of rain fell over night. Let’s check what we have learned so far: How do graphs help scientists? © Copyright NewPath Learning. All Rights Reserved.

Studying the Sun and the Earth Scientists use numbers when talking about the Earth and space too! For example: Scientists know that one rotation of Earth equals 24 hours. Studying the Moon, Stars, and Planets Scientists also use numbers to figure out how far the planets are away from the Sun. For example: Earth is 150 million kilometers from the Sun. Let’s check what we have learned so far: How long does it take planet Earth to make one rotation? Studying Earth, Yesterday and Today Scientists sort and group objects when conducting experiments too. We sort and group in Math too! Rocks, Soil, and Water Scientists COUNT too in science! Counting is MATH! Scientists count the layers of the Earth and the layers of soil too! Fossils and Dinosaurs Scientists use numbers when talking about how many years ago different animals lived on Earth. © Copyright NewPath Learning. All Rights Reserved.

Using and Saving Natural Resources When you are helping to save the Earth you can count how many bottles and cans you recycle each week! The more you recycle, the more help you are giving to make the Earth a better place! Studying Forces and Machines Scientists use numbers and charts to see how much time and effort it takes to move objects. They also use numbers and charts to see how much time and effort using simple machines saves! Studying Matter All Around Scientists use numbers and clocks during experiments. If a scientist is testing to see how long it takes an ice cube to melt, he will use a clock to measure the amount of time that goes by while the ice cube is melting. © Copyright NewPath Learning.

Studying Sound and Light What sound was the loudest? Scientists use numbers and different tools to figure this out! Which of the following listed on the chart below produced 100 decibels of sound? a) telephone b) large truck c) train horn d) rock concert The chart tells you that the train horn was 100 decibels loud. Studying Magnets Scientists can use charts and graphs to record what items are attracted by magnets and which are not. Studying Science and Technology in Our World Scientists use numbers and graphs to see how much technology helps our world! Hands-on Lab Skills Scientists use tools to MEASURE! For example: Scientists use a MEASURING CUP to measure how much of a liquid there is. Scientists use a CLOCK to tell the time and to measure how long it takes to do something. Scientists use a THERMOMETER to measure the temperature outside and inside. Scientists use a BALANCE to measure the weight of an object. © Copyright NewPath Learning. All Rights Reserved.
