In nature most elements occur as a mixture of two or more isotopes. Eachisotope of an element has a fixed mass with a natural percent abundance. The mass of theelement needs to reflect the masses of these isotopes in their respective abundances. Giventhe masses and abundances, how is the Average Atomic Mass determined?
In this activity, you will determine the atomic mass of the fictitous element Candium.

In this lesson students use a rule of thumb about the weight of babies to practice doubling and halving numbers. They complete an organized table and compare data using vertical and horizontal double bar graphs. The lesson includes a student activity sheet and extension ideas.

The Balance It App is a Task Card Resource and a simple and easy way to provide students with visual prompts to help them develop Gymnastic skills.  It is well worth the $1.99. There are over 60 balances that progressively build up in difficulty, allowing students to develop their static balance and team work skills. Balances range from Indiviual Balances, to balances of two, three, five, and large group balances.  

Here's a super fun science activity that really gets kids thinking! Children will explore  and center of gravity by creating a balancing robot!

In this lesson plan students conduct a survey of ten students, collect data in a tally chart, and then display and analyze the results in a bar graph. In the analysis students must compare numbers, add, and subtract using the data in the bar graph to generate questions as well as answer them. The lesson plan includes a graph template, a link to an interactive graphing tool, extension questions, and a fact family sheet to show the related facts from their graph analysis.

Can be used as a whole class warm-up. Integrats math. Can be easily modified. 

This resource is an example of modeling the line of best fit by plotting the number of rubber bands that form a bungee cord and how far a Barbie doll can bungee jump with the length of cord. Students calculate the line of best fit by hand and using a graphing calculator. They interpret key parts of the line such as slope and y-intercept.

The consideration of cord length is very important in a bungee jump‰ŰÓtoo short, and the jumper doesn't get much of a thrill; too long, and ouch! In this lesson, students model a bungee jump using a Barbieĺ¨ doll and rubber bands. The distance to which the doll will fall is directly proportional to the number of rubber bands, so this context is used to examine linear functions.

In this online game, students will be building numbers using Base 10 blocks.  Students decide if they want to select ones, tens, or hundreds.  Students also get to choose if they want to read the number, listen to the number, or if they want to count the blocks given and deterine the number being represented.

This interactive activity, in applet form, guides students through the motion of the sun and how they relate to seasons.

In this math activity, learners are challenged to create aluminum foil boats that will hold plastic bears until the boats sink. The lesson serves as a fun, hands-on way to collect data. Data from two attempts is collected and used to make two class box-and-whisker plots with some surprising results. This lesson guide includes questions for learners, assessment options, extensions, and reflection questions.

In this 8-lesson unit students use buttons to explore logical and numerical relationships that form the conceptual basis for understanding addition and subtraction operations. Topics include counting, ordinal numbers (and relative position), classification (attributes), relationships between numbers, addition of sets, commutativity of addition, sums to 10, fact families (including subtraction), three models of subtraction ("take away", comparative, missing addend), and bar graphs. Includes student activity sheets and a link to an online graphing applet.

This is an introductory course in biochemistry, designed for both biology and chemical engineering majors.

A consistent theme in this course is the development of a quantitative understanding of the interactions of biological molecules from a structural, thermodynamic, and molecular dynamic point of view. A molecular simulation environment provides the opportunity for you to explore the effect of molecular interactions on the biochemical properties of systems. Topics covered include: Protein Function, Structure and Function of Carbohydrates, Lipids and Biological Membranes, Metabolism, Nucleic and Acid and Biochemistry.

This is a multi-day activity in which student will learn what biomimicry is, explore current examples of biomimicry that exists in the fields of technology, engineering, humanities, social interactions and many other.  After the initial learning is completed student pair up and create a new invention that uses biomimicry.

Wisconsin's occupied bear range is expanding, which means residents can expect to see black bears in areas outside of the bear's traditional range. An abundant population and suitable bear habitat have facilitated the southerly movement of occupied bear range in Wisconsin. Wisconsin's black bear population is considerably higher than it was 30 years ago.

Wisconsin's bear population was estimated to be about 9,000 bears in 1989. The most recent data indicates the bear population is currently estimated to be a little over 24,000 bears. DNR manages bear population size through regulated hunting. The number of hunting permits have steadily increased following studies showing higher numbers of bears. In the near future, opportunities will be provided to the public to comment on the desired numbers of bears in each of the state's bear management regions as the DNR prepares a new bear management plan.

Wisconsin is not alone in its expanding bear range. The results from a 2008 survey of eastern United States and Canadian Provinces that actively manage black bear populations indicated that 75% of these jurisdictions report an increase in bear range. Only Vermont reported a contracting bear range.

In this Illuminations lesson plan students explore the use of variables as they solve for the weights of objects using information presented in pictures. Learners model situations that involve adding and subtracting whole numbers, using objects, pictures, and symbols. A student activity sheet is available and downloadable (pdf).
